Description

[Technical field]

[0001] The present invention relates to a trapping device for trapping flying pests, and more specifically, to a thread for trapping flying pests, a net made from the thread, and a method for installing the net. [Background technology]

[0002] Farmers and livestock farmers take various measures to prevent damage to crops and livestock caused by flying pests (flies, mosquitoes, moths, planthoppers, stink bugs, aphids, etc.) The main measures against flying pests include spraying pesticides, preventing their entry with insect nets, and capturing them with sticky sheets. For example, Patent Documents 1 and 2 disclose nets for capturing flying insects, the nets being treated with an adhesive. The flying pest sticky capture sheet described in Patent Document 1 is characterized in that a mesh sheet coated with an adhesive on one or both sides is pulled to expand the mesh, and the size of the mesh is preferably about 5mm to 30mm, expressed as the distance between intersections (fusion points of threads).The mesh of the mesh sheet can be expanded to break the adhesive film of the mesh and open in a thread-drawn state, and the thread-drawn state is made like a spider's web, making it possible to efficiently capture flying pests that try to pass through the mesh. However, the flying pest sticky capture sheet described in Patent Document 1 is originally intended to detect the occurrence of flying pests within a cultivation greenhouse, and is small in size, and there is no mention or suggestion of placing a capture sheet over a wide range of flying pest entry routes to capture them, as in the present invention. In addition, the sticky flying insect trap sheet described in Patent Document 1 is such that flying insects cannot pass through the mesh of the sticky flying insect trap sheet and are trapped in the sticky part, and if the trap sheet described in Patent Document 1 is installed in the same manner as the present invention, the mesh is small, from 5 mm to 30 mm, so it is prone to clogging with dust and poor ventilation. The reduced breathability of the sticky flying insect trap sheet leads to poor ventilation inside greenhouses and livestock houses, which causes stress to agricultural crops and livestock.

[0003] The adhesive trapping device described in Patent Document 2 is for trapping flying pests with a net treated with an adhesive, and describes an adhesive trapping device made of polyethylene net with a mesh size of 5 mm, length 50 cm, and width 50 cm immersed in an adhesive, and an adhesive trapping device made of coated paper with cuts, 11 mm incisions made at 3 mm intervals in the vertical direction and 2 mm intervals in the horizontal direction, and treated with an adhesive. The adhesive trapping device is endowed with a trapping performance that covers the source of pest infestation, allowing flying pests to attach immediately after their infestation, and even if there is a gap between the covered area and the source, before the pests find it. The essence of the technology described in Patent Document 2 is to cover the sources of flying pests, but the sources of flying pests are not limited to within the greenhouse but can also be found outside the greenhouse, and usually these sources extend to multiple locations. Meanwhile, depending on the type of flying pest, the source may be located several kilometers away from the greenhouse that is the subject of damage, so it is impossible to cover each and every one of the numerous sources that exist over a wide area. Furthermore, flying pests that emerge from a source outside the greenhouse grow into adults and invade the greenhouse, so the technology disclosed in Patent Document 2 above cannot efficiently eliminate damage caused by flying pests.

[0004] Among flying pests, stable flies are a particular issue for livestock farmers. Stable flies are small flies with needle-shaped mouths that gather on cattle, horses, pigs, etc. and suck their blood. Adult stable flies are about 3mm to 8mm in size. Unlike flies, stable flies cause great stress to livestock due to their blood-sucking nature. Livestock bitten by stable flies become abnormally nervous due to the pain and itching caused by the bite, reduce feed intake, and spend the whole day standing up. Furthermore, livestock are seen to become unruly in livestock sheds, which may lead to accidents, and stable flies are flying pests that cannot be ignored in terms of livestock efficiency. In this regard, neither Patent Document 1 nor Patent Document 2 provides technology that has been devised with a focus on measures against stable flies, which cause serious damage to livestock. Rather, the emphasis is placed on measures to prevent flying insects that are harmful to greenhouse cultivation of vegetables, etc. and to cultivation workers, and the provision of technology to control stable flies has been awaited.

[0005] Meanwhile, Patent Document 3 discloses a simple capture technology that uses an adhesive sheet to capture flying pests, unlike the capture nets disclosed in Patent Documents 1 and 2. Patent Document 3 also addresses the technical issues of Patent Documents 1 and 2 in terms of capturing flying pests or providing devices for capturing flying pests, but it also includes points that differ from these issues, and discloses a technical idea that includes a solution to serious issues that affect the livestock industry, particularly with flying pests such as stable flies (Stomoxys calcitrans) that have a biting ability and suck blood from cattle. However, according to Patent Document 3, although the objective is to provide a flying insect capture device that is excellent in the working environment, whose capture performance is not easily impaired by rain, etc., is low cost, and is easy to replace or dispose of, it is limited to the stable capture achieved by conventional adhesive sheets and does not fully take into account the movement habits and peculiarities of stable flies (such as the applicant's research results described below), and is therefore insufficient in terms of capture selectivity and capture efficiency for stable flies. As described in Non-Patent Document 1, measures to combat stable flies include cleaning up infested areas, spraying pesticides, installing insect nets, and eliminating resting places. However, these measures are not sufficient in various respects. For example, in the case of pesticides, wettable powders and aerosols are effective against flies and mosquitoes to a certain extent, but stable flies retreat temporarily and then return quickly. Molting inhibitors must be sprayed over a wide area outside the barn, and the amount sprayed is an issue, which can lead to soil contamination. As for eliminating resting places, there are naturally limitations, as it is often difficult to eliminate grass patches depending on the environment around the barn. In particular, for insect-proof nets, the mesh size should preferably be 2mm or less, because this mesh size will result in poor ventilation inside the livestock barn, and there are concerns that the temperature inside the barn will rise from May to late autumn, when stable flies are likely to appear. As mentioned above, rising temperatures inside the barn will cause excessive stress to the livestock. Furthermore, Non-Patent Document 1 states that there is no difference in temperature inside livestock barns with and without insect netting, but this is because the livestock barns in question are ones in which heat protection measures have been taken; this does not apply to livestock barns in which heat protection measures have not been taken. In addition, although it is said that the mesh size of the net is preferably 2 mm or less, this is not appropriate, since dust that adheres to the net clogs the mesh, and therefore dust must be removed periodically, regardless of whether this is a preventative measure or not. In addition, when insect nets are installed, stable flies are placed in an environment that is "difficult to enter and difficult to exit." This means that once a stable fly enters the insect net, it cannot get out and will survive inside the net. Even if a stable fly is found inside the insect net and an insecticide is sprayed on it, it will fly away from the net before the lethal dose is sprayed, so the insecticide will not be killed. In addition, if the insecticide is sprayed throughout the livestock barn, the barn will be almost sealed due to the reduced breathability caused by the insect net, so spraying a lethal dose will have a concern about the impact on the livestock inside the barn. In this way, stable flies that have entered the insect net cannot get out and are difficult to kill, which leads to them surviving and breeding inside the barn. In view of the above-mentioned conventional techniques, the inventors of the present application attempted to grasp the migratory habits and peculiarities of stable flies and to take drastic measures.

[0006] (Discovering the habits of stable flies) The stable flies' resting places are the grasslands around the livestock barns. When we looked closely at the resting places, we found that they often rest on linear grass or uneven trees. This is a habit that stable flies are born with. Support for this can be seen in the behavior of stable flies when sucking blood from livestock. When a stable fly pierces a target, it needs to fix itself to the target to resist the repulsive force of its own piercing force. In addition, as its own weight increases during the blood-sucking process, it must be prevented from being shaken off from the target. For this reason, the stable fly needs to firmly grasp (hold on to) the target. It was found that the stable flies often rest on linear or uneven vegetation, etc., as a survival habit of the stable flies. The discovery of this habit led to the basic configuration of the present invention.

[0007] (Irregular special behavior discovered) Stable flies generally invade from sunny places on the south side, southeast or southwest side. They usually invade up to 1m above ground level, and can invade from one end of the barn to the other. It was found that stable flies behave erratically around the barn before invading the barn. Although it is not possible to say for sure, it is thought that this is a scouting or mating behavior. It was found that the stable flies repeatedly flew in a zigzag pattern within a 2m radius around the barn. The discovery of this behavior provided a hint for the location of the installation of the present invention.

[0008] (The invention described herein allows stable flies to pass through safely) Due to the above behavior, stable flies do not like to land on flat, planar objects. This can also be inferred from the fact that when they invade livestock sheds from the outside, they rarely land on the exterior walls of the sheds. For stable flies, planar objects are obstacles that block their entry path, so it seems inevitable that they will avoid them and enter through open spaces. A planar object is, for example, a wall, and is a surface with an area larger than the body length of the stable fly. From this, the inventor came up with the idea of ​​creating a place (a linear area where stable flies can cling) that stable flies can pass through and rest in the space where stable flies invade (within a range of 1m from the ground and 2m inside and outside the livestock barn perimeter) and achieved the present invention. When the present invention was installed in the space where stable flies invade, it led to great results in terms of the number of stable flies caught.

[0009] In addition, the present invention can be installed in all locations where stable flies are likely to enter, which leads to a further increase in the number of stable flies captured. The insect repellent net described in the above-mentioned Non-Patent Document 1 preferably has a mesh size of 2 mm or less, and other insect repellent nets with mesh sizes of 2 mm x 4 mm and 6 mm x 6 mm are also sold as nets to prevent the intrusion of stable flies. However, the mesh of any net is too small to allow wind to pass through, and the installed insect-proof net is easily affected by the wind. Therefore, if there are many places where stable flies can enter the livestock house, installing insect-proof nets at all of the entry points will reduce the airflow inside the livestock house and increase the temperature, which will cause stress to the livestock. In this regard, the present invention is a net with thread or mesh spacing of at least 5cm to 15cm, so it does not impair air circulation within the livestock barn and is not affected by wind, and can be installed in all locations where stable flies may enter. Therefore, by installing the present invention over a wider area, a greater number of stable flies can be captured. [Prior art documents] [Patent documents]

[0016] Preferred embodiments of the flying insect capture thread and flying insect capture net of the present invention will be described in detail below with reference to Figures 1 to 6 and 12. However, as long as the object and effect of the present invention are not impaired, the present invention is not limited to the following examples. (1) Overview of the embodiment A thread with a wire diameter of 1.5mm to 3mm coated or impregnated with an adhesive, and a net made of said thread, are set up to capture flying pests. When multiple threads are set up, there is a gap of 3cm to 5cm between each thread in at least a part of the thread, and when a net is constructed, there is a gap of 5cm to 15cm between each thread that constitutes the mesh of the net in at least a part of the thread.

[0017] (2) Details of the embodiment The flying insect trapping thread 1 comprises a thread 11 and an adhesive part 12 formed by coating or impregnating the thread 11 with an adhesive. The yarn 11 may be a single yarn or a twisted yarn. A single yarn is made up of a single thread, whereas a twisted yarn is made up of multiple single yarns twisted together. The material of the single yarn may be, for example, nylon, polyester, polyethylene, polypropylene, etc., and the yarn diameter may be in the range of 1.5 mm to 3 mm. In the case of twisted yarn, as in the case of single yarn, the material may be, for example, nylon, polyester, polyethylene, polypropylene, etc., and the composition may be, for example, 10 twisted strands of 400 denier, with the wire diameter of the entire twisted yarn being in the range of 1.5 mm to 3 mm.

[0018] The thread 11 constituting the flying insect trapping thread 1, whether single thread or twisted thread, preferably has a wire diameter of 1.5 mm to 3 mm, in consideration of the thickness considered to be suitable for embracing the stable fly with its legs when landing, based on the body length of the stable fly. If the wire diameter of the flying insect trapping thread 1 is too thin for the body length of the stable fly, even if the stable fly lands on the flying insect trapping thread 1, the contact area between the adhesive part 12 of the flying insect trapping thread 1 and the stable fly will be small, increasing the possibility that the stable fly will fly away from the flying insect trapping thread 1. On the other hand, if the flying insect trapping thread 1 is too thick, the stable fly will not be able to embracing the flying insect trapping thread 1, and the possibility that the stable fly will land on the flying insect trapping thread 1 will be low.

[0019] The color of the flying insect trapping thread 1 may be yellow, green, brown, black, or the like. No change in the number of captured stable flies was observed depending on the color of the flying insect trapping thread 1. However, when capturing flying pests other than stable flies, if the number of captured insects increases depending on the color of the flying insect trapping thread 1 depending on the nature of the flying pest, the color of the flying insect trapping thread 1 can be appropriately selected depending on the nature of the flying pest to be captured. For example, in a greenhouse for cultivating fruits and vegetables, moths, planthoppers, stink bugs, and other pests fly and need to be exterminated, and the pests can be captured by installing the flying insect trapping thread 1. By making the color of the thread 11 of the flying insect trapping thread 1 yellow, further pest capture can be expected.

[0020] The adhesive portion 12 is formed by applying or impregnating a liquid adhesive to the thread 11 constituting the flying insect trapping thread 1. If the material of the thread 11 constituting the flying insect trapping thread 1 allows liquid to be absorbed, the adhesive portion 12 can be formed by impregnating the thread 11 constituting the flying insect trapping thread 1 with an adhesive. If the material of the thread 11 constituting the flying insect trapping thread 1 does not allow liquid to be absorbed, or if the adhesive does not seep onto the surface of the thread 11 constituting the flying insect trapping thread 1 over time, the adhesive can be applied to the thread 11 constituting the flying insect trapping thread 1. For example, if the yarn 11 is a single yarn made of polyester, the adhesive portion 12 is formed by applying an adhesive to the yarn 11, and if the yarn 11 is a twisted yarn made of polyester, the adhesive portion 12 is formed by impregnating the yarn 11 with an adhesive so that the adhesive is also contained between each of the yarns that make up the twisted yarn.

[0021] The adhesive constituting the adhesive portion 12 can be selected from various known adhesives according to the weather and season. The adhesive may be any of silicone adhesives made of polymers with siloxane bonds as the main skeleton, acrylic adhesives made of acrylic polymers, urethane adhesives made of polyurethane obtained by condensing compounds having isocyanate groups and hydroxyl groups, and natural rubber adhesives, and may be used in combination as desired. Of these, it is preferable to use polybutene or the like as the component. The adhesive may be applied in the form of either a liquid coating type or a spray type, and as described above, an appropriate type may be selected and used depending on the material of the thread. The adhesive portion 12 must be strong enough to prevent stable flies that land on the flying insect trapping thread 1 from flying away easily.

[0022] Next, the operation of the embodiment configured as above will be described. In the present invention, cows are assumed to be representative of livestock raised in barns, but the same applies to pigs, horses, etc. The flying insect catching line 1 is set outside or inside the livestock house. Since stable flies prefer sunlight, they are more likely to invade livestock sheds from the south side than from the north side. For this reason, it is expected that many stable flies will be caught by placing the flying insect trapping thread 1 mainly on the south side of the livestock shed. In addition, stable flies often invade from resting areas and places where people come and go, so stable flies can be prevented from invading the livestock shed by setting up the flying insect trapping thread 1 near resting areas and entrances where people come and go, depending on the environment around the livestock shed.

[0023] When setting up the flying insect trapping line 1 outside the livestock shed, the flying insect trapping line 1 is set parallel to the livestock shed at a distance of approximately 1 to 2 m from the livestock shed, based on the width of 2 m on each side of the zigzag flight of a stable fly, which is roughly a Z shape when viewed from above. In a livestock shed where the feed trough is provided on the outside of the livestock shed, the flying insect trapping thread 1 is placed at a position 1 to 2 m away from the feed trough, on the outside of the aisle. In the case of a livestock barn in which the feed trough is provided inside the barn, the flying insect catching thread 1 is set at a position about 1 to 2 m from the outer fence of the cow pen. When the flying insect trapping thread 1 is set up inside a livestock shed, the location for setting it up can be appropriately selected depending on the structure of the livestock shed.

[0024] In addition, in cases where livestock can move directly from one barn to the outside, that is, where the barn has an attached pasture, setting up the flying insect trapping line 1 around the barn is not enough to catch stable flies, so it is necessary to set up the flying insect trapping line 1 around the pasture. In this case, the flying insect trapping line 1 is set on the outside of the fence that separates the pasture from other areas, in a position that cannot be reached by the heads of livestock, specifically their horns and mouths. This is to prevent the livestock from accidentally ingesting the flying insect trapping line 1.

[0025] As mentioned above, most stable flies fly at a height of about 1 m above the ground. For this reason, it is preferable to set the flying insect trapping thread 1 at a position 1 m above the ground from a position where the flying insect trapping thread 1 does not touch the ground. However, when the target of capture is a flying insect other than stable flies or depending on the occurrence of stable flies, the flying insect trapping thread 1 can be set at a position more than 1 m above the ground.

[0026] FIG. 1 is a diagram showing an example of how to set up (stretch) a flying insect trapping thread 1. The flying insect trapping thread 1 is set vertically (hereinafter referred to as "vertical laying"), horizontally (hereinafter referred to as "horizontal laying"), or at an angle (hereinafter referred to as "diagonal laying") to the ground, either individually or in multiples. When setting up, a support pole may be provided to fix both ends of the flying insect trapping thread 1, or the ends of the flying insect trapping thread 1 may be fixed to an existing pole, such as a pole supporting a livestock shed. When a plurality of flying insect trapping threads 1 are installed, a space of 3 cm to 5 cm is provided at least partially between each pair of flying insect trapping threads 1 in the X or Y direction.

[0027] As shown in Fig. 1(a), when multiple flying insect threads 1 are installed in the same direction, they are installed 3 to 5 cm apart. Also, as shown in Fig. 1(b), the flying insect threads 1 do not necessarily need to be arranged in a straight line, but may be installed in a zigzag pattern (hereinafter sometimes simply referred to as an approximate Z shape) when viewed from above, so that the flying insect threads 1 move back and forth in the Z direction, that is, when viewed from the front. As shown in Fig. 1(c), the flying insect trapping threads 1 may be installed in a combination of vertical and horizontal laying. In this case, when installing three or more flying insect trapping threads 1, if the vertically laid flying insect trapping threads 1 and the horizontally laid flying insect trapping threads 1 come into contact with and intersect with each other to form a grid, the flying insect trapping threads 1 may be installed so that the distance between at least a part of the grid formed, for example, on the diagonal line, is 10 cm to 15 cm.

[0028] 1(d), when two flying insect trapping threads 1 are stretched diagonally, there is no designation for the angle at which each flying insect trapping thread 1 is set, and it is sufficient that the two flying insect trapping threads 1 are spaced apart by at least 3 to 5 cm at any position. When multiple flying insect trapping threads 1 are stretched diagonally and the two flying insect trapping threads 1 come into contact with each other and cross, a grid is formed, but even in this case, it is sufficient that the flying insect trapping threads 1 are set so that at least some of the grids are spaced apart by 5 to 15 cm. Regardless of the above-mentioned way of stretching the flying insect trapping thread 1, when multiple flying insect trapping threads 1 are set with a staggered arrangement in the Z direction, it is preferable to arrange them so that they do not overlap in the X and Y directions. This is because, based on the habit of stable flies swinging left and right in their flight direction, it is presumed that the probability of stable flies landing is higher when the flying insect trapping threads 1 are set at staggered heights than when multiple flying insect trapping threads 1 are set at the same height. In addition, although there is no specification for the distance between each flying insect trapping thread 1 in the Z direction, it is preferable to set the flying insect trapping threads 1 at a distance that does not contact other flying insect trapping threads 1.

[0029] Whether the flying insect trapping thread 1 is set vertically or horizontally, there is no significant difference in the number of stable flies caught. When stable flies attach to livestock, they attach by embracing the livestock's fur, and most stable flies will attach with their heads up if they are attaching to the livestock's legs, and will embracing the fur from below if they are attaching to the livestock's underbelly. Similarly, most stable flies that land on the flying insect trapping thread 1 will embracing the thread 11 with their heads up if the flying insect trapping thread 1 is set vertically, and most stable flies will embracing the thread 11 from below if the flying insect trapping thread 1 is set horizontally, i.e., they will hang from the thread 11. Given the habits of stable flies, it is presumed that whether the flying insect trapping line 1 is laid vertically or horizontally does not have a significant effect on the number of stable flies captured, and in order to increase the number of stable flies captured with the flying insect trapping line 1, it is important that there is empty space around the flying insect trapping line 1.

[0030] As described above, according to the preferred flying insect trapping thread 1 of this embodiment, the thread 11 having an adhesive portion 12 and a wire diameter of 1.5 mm to 3 mm is set up so that at least a part of it has a blank portion in the range of 3 cm to 5 cm, or 5 cm to 15 cm, where there are no other flying insect trapping threads 1, thereby making it possible to efficiently trap flying pests including stable flies.

[0031] Next, a second preferred embodiment will be described. In the first embodiment, the flying insect trapping thread 1 of the first embodiment is configured as a "thread," whereas in this second embodiment, the flying insect trapping thread 1 of the first embodiment is configured as a "net." FIG. 2 shows an example of the configuration of the flying insect trap net 2 in the second embodiment.

[0032] Each thread constituting the flying insect trapping net 2 can use the flying insect trapping thread 1. The shape of the mesh of the net may be a square, diamond, etc., as shown in Fig. 2. The mesh may have various shapes, but as described in the first embodiment, each mesh is configured such that the distance between each flying insect capturing thread 1 constituting the flying insect capturing net 2 is 5 cm to 15 cm at least in a part of the mesh. As will be seen from the test results described later, the shape of the mesh does not significantly affect the capture rate of stable flies, and it is essential that the flying insect capture net 2 is configured so that at least a portion of the mesh is spaced 5 cm to 15 cm apart.

[0033] The height of the flying insect capture net 2 is preferably about 1 m. As described above, this is because most stable flies fly within a range of about 1 m above the ground. The width of the flying insect trapping net 2 is preferably about 6 m from the viewpoint of ease of tensioning when installing the flying insect trapping net 2. The width of the flying insect trapping net 2 can also be appropriately selected depending on the material of the flying insect trapping thread 1 constituting the flying insect trapping net 2. For example, if the flying insect trapping thread 1 is made of a material that is prone to tangling, the flying insect trapping net 2 will also be more prone to tangling, so it is easier to handle when installing the flying insect trapping net 2 if the width of the flying insect trapping net 2 is not too long.

[0034] Next, the installation (stretching) of the flying insect capture net 2 will be described. When installing the flying insect trapping net 2, supports may be provided to fix both ends of the flying insect trapping net 2, or the ends of the flying insect trapping net 2 may be fixed to existing pillars, such as pillars supporting a livestock shed. The location of the flying insect trap net 2 is as described in the first embodiment. Similarly to the first embodiment, the installation position of the flying insect trapping net 2 is preferably set at a position about 1 m above the ground so that the flying insect trapping net 2 does not come into contact with the ground.

[0035] The flying insect trapping net 2 may also be installed in the Z direction, that is, so that the flying insect trapping net 2 is substantially Z-shaped, as shown in the first embodiment. In this case, the flying insect trapping net 2 can be stretched substantially Z-shaped by using multiple supports, as shown in FIG. 1(b). In Fig. 3, instead of providing multiple supports to arrange the flying insect trapping net 2 in a substantially Z-shape, the flying insect trapping net 2 is laid between two parent threads in a zigzag pattern, allowing the flying insect trapping net 2 to be installed in a substantially Z-shape. As shown in Fig. 3, the flying insect trapping net 2 is fixed to the parent threads between the two parent threads so that the flying insect trapping net 2 is in a substantially Z-shape. The position at which the flying insect trapping net 2 is fixed to the parent threads can be selected as appropriate, but it is preferable that the flying insect trapping net 2 be fixed at a position where the distance between the two parent threads is 30 cm to 50 cm when installing the flying insect trapping net 2. In the Y direction, parent threads are also provided at the upper and lower ends of the flying insect capture net 2, but if the parent threads at the upper and lower ends alone are not able to maintain the approximate Z shape of the flying insect capture net 2, parent threads can be added as appropriate according to the height of the flying insect capture net 2. For example, a parent thread can be added at the midpoint in the Y direction.

[0036] In addition, when there is a large amount of stable flies, two rows of flying insect capture nets 2 may be installed in parallel. In this case, it is optional to alternately shift the mesh frame units of the front and back rows of nets. In addition, when capturing other flying pests including stable flies, such as mosquitoes and flies, a flying insect capture net 2 may be installed about 1 m above the ground, and a flying insect capture net 2 may be installed above the flying insect capture net 2.

[0037] Next, a third preferred embodiment will be described. In the third embodiment, an insect catching member 3 is provided on the flying insect catching thread 1 of the first embodiment and the flying insect catching net 2 of the second embodiment. FIG. 4 shows an example of the configuration of the insect trapping member 3 in the third embodiment.

[0038] The insect catching member 3 is provided on the flying insect catching thread 1 or the flying insect catching net 2 for the purpose of improving the rate of catching stable flies. As mentioned above, stable flies prefer to land on linear objects, and the flying insect capture thread 1 and the flying insect capture net 2 are constructed based on this habit. Moreover, since stable flies fly in a zigzag pattern, they will pass through the meshes of, for example, the flying insect capture net 2. Furthermore, the present invention does not expect stable flies to fly around the flying insect trapping thread 1 or through the mesh of the flying insect trapping net 2, and accidentally come into contact with the flying insect trapping thread 1 or the flying insect trapping net 2, and be captured by the sticky parts of the flying insect trapping thread 1 or the flying insect trapping net 2. That is, the present invention is configured in consideration of the flying habits of stable flies and their habits regarding preferred landing places, so that flying stable flies will land on the flying insect capture thread 1 or the flying insect capture net 2 of their own accord. The insect trapping member 3 is intended to increase the capture rate of stable flies by increasing the number of areas on which stable flies passing around or through the mesh of the flying insect trapping thread 1 or the flying insect trapping net 2 can land.

[0039] Specifically, the insect trapping member 3 is made up of a trapping short thread 31 that is made up of the flying insect trapping thread 1 with a length of 5 cm to 15 cm. The insect trapping member 3 is made up of one to a plurality of trapping short threads 31. Since space is necessary for stable flies to fly, when the insect trapping member 3 is made up of a plurality of trapping short threads 31, at least a portion of the space between each pair of the trapping short threads 31 is set to be 5 cm to 15 cm. FIG. 4(a) shows an example in which an insect catching member 3 is attached to a flying insect catching thread 1. The insect catching members 3 are attached so as to protrude from the flying insect trapping thread 1. There are no particular limitations on the angle at which the insect catching members 3 protrude from the flying insect trapping thread 1 to which they are attached, and it is sufficient that there is a distance of 10 cm to 15 cm between the insect catching members 3 and the flying insect trapping thread 1 to which they are attached, at least in part. Similarly, when multiple insect catching members 3 are attached, it is sufficient that there is a distance of 10 cm to 15 cm between each of the insect catching members 3 and between the insect catching members 3 and the flying insect trapping thread 1 to which they are attached, at least in part. Fig. 4(b) shows an example of an insect catching member 3 attached to a flying insect catching net 2. When attaching the insect catching member 3 to the flying insect catching net 2, the insect catching member 3 is attached so as to protrude from the flying insect catching net 2, similar to the case of attaching it to the flying insect catching thread 1. In Fig. 4(b), the insect catching member 3 is attached to the so-called node portions of the mesh of the flying insect catching net 2.

[0040] The insect catching member 3 can be attached to the flying insect catching thread 1 or the flying insect catching net 2 by tying together the trapping short threads 31 constituting the insect catching member 3. For example, the length of the trapping short thread 31 can be set to 10 cm to 30 cm, and the center of the trapping short thread 31 can be tied to the flying insect catching thread 1 or the flying insect catching net 2 to form two trapping short threads 31 of 5 cm to 15 cm. Alternatively, the insect trapping member 3 may have an attachment portion 32 and a trapping short thread holding portion 33. The attachment portion 32 has a recess that engages with the wire diameter of the flying insect trapping thread 1 constituting the flying insect trapping thread 1 or the flying insect trapping net 2, and the insect trapping member 3 is attached by engaging the recess of the attachment portion 32 with the flying insect trapping thread 1 or the flying insect trapping net 2. The trapping short thread holding portion 33 is provided at a position opposite the attachment portion 32 and holds the trapping short thread 31. If the trapping short thread 31 cannot stay at a desired position due to its own weight and hangs down along the flying insect trapping thread 1 or the flying insect trapping net 2, the trapping short thread holding portion 33 may have a trapping short thread support portion 34 that supports the trapping short thread 31 to hold the trapping short thread 31 at a desired position. The catch short yarn support part 34 is, for example, a wire or the like having a smaller diameter than the catch short yarn 31 and is inserted into the catch short yarn 31 from the other end thereof to support the catch short yarn 31 .

[0041] The insect catching member 3 does not need to be made of the same material as the flying insect trapping thread 1 or the flying insect trapping net 2 to which the insect catching member 3 is attached. For example, if the trapping short thread 31 is made of twisted yarn, depending on the twisted yarn used, the trapping short thread 31 may sag along the flying insect trapping thread 1 or the flying insect trapping net 2 to which the insect catching member 3 is attached due to the weight of the twisted yarn or the like. The insect catching member 3 is attached so as to protrude from the flying insect trapping thread 1 or the flying insect trapping net 2, making it easier for stable flies to land on it. In such a case, even if the flying insect trapping thread 1 or the flying insect trapping net 2 is made of twisted yarn, it is preferable to form the trapping short thread 31 from a single yarn that is tauter than the twisted yarn.

[0042] FIG. 5 shows an example of the configuration of the support frame 5. As shown in FIG. The support frame 5 is a frame for stretching the flying insect catching thread 1 and the flying insect catching net 2. In any of the first to third preferred embodiments, the flying insect trapping thread 1 and the flying insect trapping net 2 are installed using existing pillars or the like at the installation site, or a support is prepared and fixed to the pillar. Therefore, to move the installed flying insect trapping thread 1 and the flying insect trapping net 2, the flying insect trapping thread 1 and the flying insect trapping net 2 are basically removed together with the support, and then reinstalled in the desired position. When movable supports are used to install the flying insect trapping thread 1 and the flying insect trapping net 2, the flying insect trapping thread 1 and the flying insect trapping net 2 can be moved together with the support without removing the flying insect trapping thread 1 and the flying insect trapping net 2 from the support.

[0043] The adhesive strength of the adhesive portion 2 of the flying insect trapping thread 1 and the flying insect trapping net 2 may decrease when they get wet from rain. For this reason, by stretching the flying insect trapping thread 1 and the flying insect trapping net 2 on the support frame 5, the support frame 5 can be moved to under the eaves or the like during rainy weather, making it easy to prevent the flying insect trapping thread 1 and the flying insect trapping net 2 from getting wet from rain and preventing a decrease in adhesive strength. Furthermore, when reinstalling, it is only necessary to set the support frame 5 in the desired position. The support frame 5 shown in Fig. 5 is a frame surrounding all four sides and is composed of top, bottom, left and right poles. The receiving members 51 have recesses into which the poles of the support frame 5 are hung. The locking members 52 lock the flying insect trapping net 2 to the poles of the support frame 5. The fixing members 53 are provided on both ends of the top and bottom poles and lock both ends of the flying insect trapping net 2.

[0044] As shown in FIG. 5, the receiving member 51 is attached to an existing pillar or the like of the livestock house. As mentioned above, most stable flies fly at a height of about 1 m above the ground. In order to utilize this behavior of stable flies to improve the trapping effect of stable flies in this embodiment, it is preferable that the lower ends of the flying insect trapping thread 1 and the flying insect trapping net 2 stretched over the support frame 5 are as close to the ground as possible. The attachment positions of the receiving members 51 for hanging the upper and lower poles are determined by the height of the flying insect net 2 used on the support frame 5. More specifically, the attachment position of the receiving member 51 for hanging the lower pole is a position where the lower pole rubs against the floor, and the attachment position of the receiving member 51 for hanging the upper pole is a position where the flying insect net 2, which is engaged with the engaging members 52 of the upper and lower poles, is engaged with the support frame 5 without bending in the height direction when the upper and lower poles are respectively hung on the receiving parts 51. The same applies to the case where the flying insect thread 1 is fastened to the support frame 5.

[0045] The locking members 52 are ring-shaped, and a plurality of them are inserted into the upper and lower poles, respectively, and the flying insect trapping net 2 is locked to each of the locking members 52. The fixing members 53 are fixed to both ends of the upper and lower poles and engage both ends of the flying insect trapping net 2 to prevent the flying insect trapping net 2 from sagging within the support frame 5. The diameter of the locking member 52 is larger than the diameter of the pole, and there is a play between the locking member 52 and the pole, so that the locking member 52 can move on the pole with the pole inserted. This allows one end of the flying insect trapping net 2 to be removed from the fixing member 53 at one end of the upper and lower poles, and the flying insect trapping net 2 to be moved to the other end side. In rainy weather, the flying insect trapping net 2 can be moved to one end of the support frame 5 without moving the support frame 5 itself to avoid being hit by rain, and covered with a rainproof sheet such as vinyl, thereby preventing the flying insect trapping net 2 from getting wet with rain. In this case, since the support frame 5 itself does not move, the support frame 5 can be made to have only upper and lower poles without the left and right poles. A bag for inserting the flying insect trapping net 2 may be provided in the position of the removed pole.

[0046] Next, a fourth preferred embodiment will be described. 6, 11 and 12 show an example or a modified example of the configuration of the flying insect trap 4 in the fourth embodiment. The flying insect trap 4 is made up of one or more frame parts 41, support parts 42 that support the frame parts 41, and a base part 43 that supports the support parts 42. The frame parts 41 and the support parts 42 can be made of any suitable material such as metal or PVC, with a lightweight material that is resistant to rain and corrosion being preferred. Considering the flight habits of stable flies, the height of the flying insect trap 4 is preferably about 1 m.

[0047] The frame 41 is a frame for stretching the flying insect catching thread 1 and the flying insect catching net 2. As shown in Fig. 6, the frame 41(a) is open only at the top and bottom and has open sides. It can be used when the flying insect catching thread 1 is stretched vertically or the flying insect catching net 2 is used. The frame 41(b) has closed sides and can be used when the flying insect catching thread 1 is stretched horizontally. The method of attaching the flying insect trapping thread 1 and the flying insect trapping net 2 to the frame 41 can be selected as appropriate. The flying insect trapping thread 1 may be directly tied to the frame 41, or a fixing member such as a hook for fixing each flying insect trapping thread 1 or each flying insect trapping net 2 may be provided on the frame 41, and the flying insect trapping thread 1 or each flying insect trapping net 2 may be attached to the fixing member. When multiple flying insect trapping threads 1 are stretched on the frame 41, they are attached with an interval of at least 3 cm to 5 cm between each other, as described above.

[0048] The width of the frame 41 can be appropriately determined depending on the installation location of the flying insect trap 4. For example, when the flying insect trap 4 is installed in a passageway with a width of 1 m, and multiple frames 41 are arranged diagonally around the support posts 42 as shown in Fig. 6, it is desirable that the width of the frames 41 is 50 cm or less. This is because the width of the entire flying insect trap 4 would exceed 1 m, making it impossible to pass through the installation location. Alternatively, the frame 41 may be made detachable from the support posts 42, and any frame 41 that becomes an obstacle, such as obstructing passage, at the installation location may be removed as appropriate for use. The frame portion 41 is attached so as to be rotatable around a support post 42 . Since stable flies fly by rubbing against the ground, it is preferable that the lower end of frame 41 be close to the ground on which flying insect trap 4 is installed. In the flying insect trap 4 shown in Fig. 6, the frame 41 is configured to be positioned such that the lower end of the frame 41 does not come into contact with the base 43. However, if the shape of the base 43, for example, exceeds 20 cm in height, causes the distance between the lower end of the frame 41 and the ground on which the flying insect trap 4 is installed to be large, which is thought to affect the capture rate of stable flies, the frame 41 may be configured such that the lower end of the frame 41 avoids the base 43 and extends to the vicinity of the ground on which the flying insect trap 4 is installed. In this case, the frame 41 has a shape such that the extended portion does not come into contact with the base 43 when rotating around the support 42.

[0049] The support portion 42 supports one or more frame portions 41. In this embodiment, as shown in Fig. 6, the flying insect trap 4 has four frame portions 41. Each frame portion 41 attached to the support portion 42 is designed to ensure a distance of 5 cm to 15 cm or more between adjacent frame portions 41 at least in part, and multiple frame portions 41 can be attached to the support portion 42 within a range that ensures such distance.

[0050] The base 43 supports the support posts 42 and the frame 41, and also prevents the flying insect trap 4 from easily tipping over. The base 43 needs to have a weight that will prevent the flying insect trap 4 from tipping over when the flying insect trap 4 is installed, and this weight may be provided by the base 43 itself, or may be added to the base 43 when the flying insect trap 4 is installed. When adding weight to the base 43 when installing the flying insect trap 4, for example, the base 43 may consist of three legs that spread apart, and weight blocks or the like may be placed on the legs to support the flying insect trap 4. Furthermore, when the base 43 is heavy, the base 43 may be configured to have wheels to facilitate the movement of the flying insect trap 4. The wheels for moving the flying insect trap 4 may be provided directly on the bottom of the base 43, or the wheels may be provided on a platform for loading the base 43, and the base 43 may be loaded on the platform. Here, Fig. 12 is disclosed as a specific modified example of these. Fig. 12 shows a telescopic arm type mobile trap, which is configured with a telescopic function on the frame so that not only can it be easily moved, but also the net itself can be telescopic. This telescopic arm type mobile trap is installed on the outside of a livestock barn, and if it rains the arms can be folded up and moved inside. Inside, the arms can also be extended or retracted depending on the nature of the work. The actual usage is briefly explained below. Inside the frame, a cylinder with the adhesive net rolled up before use is attached to the center of the support. The cylinder is preferably made of plastic and has a double structure consisting of an inner cylinder and an outer cylinder. Before installation, the net is wrapped around the inner tube, the outer tube is capped, and then adhesive is poured in to soak into the net. Then, set it in the trap. If you are using an adhesive net, remove the outer tube, pull it to the tip of the arm, and fasten it to the ring. Cover the remaining sticky net to prevent it from drying out. In addition, a reservoir for residual adhesive is provided at the bottom of the tube. After use, the net is removed from the ring and disposed of as combustible waste.

[0051] The material of the base 43 mentioned above differs depending on whether the weight of the base 43 is provided by the base 43 itself or whether weight is added to the base 43 when the flying insect trap 4 is in use, and can be selected appropriately from materials such as metal and concrete. The shape of the base 43 can be appropriately selected from shapes such as a rectangular parallelepiped, a truncated pyramid such as a square or triangular pyramid, a cylindrical shape, and also shapes such as legs that can be spread apart as described above. Although this depends on the material and shape of the base 43, in general, for example, if the height of the base 43 is lowered, the bottom area of ​​the base portion 43 that comes into contact with the ground on which the flying insect trap 4 is installed will be larger, and if the height of the base 43 is increased, the bottom area of ​​the base 43 will be smaller. When the frame 41 is configured so that the lower end of the frame 41 does not come into contact with the base 43, it is preferable to configure the height of the base 43 low so that the distance between the lower end of the frame 41 and the ground is short. Since stable flies have the habit of flying close to the ground, it is possible to capture stable flies by setting the distance from the ground to the bottom of the frame 41 to about 10 cm. The material for the base 43 may be a heavy iron plate that is not tall.

[0052] A capture test was carried out on the flying insect trapping thread 1, the flying insect trapping net 2, the flying insect trap 4, and the flying insect trapping thread 1, the flying insect trapping net 2, and the flying insect trap 4 with the insect trapping member 3 attached thereto, obtained in the above-mentioned embodiments 1 to 4. (Capture Test 1) 1. Purpose Tests were conducted to examine the difference in flying insect capturing performance between a commercially available insect-trapping sheet and the present invention, and to examine the flying insect capturing performance of the present embodiment. 2. Method (1) Date and time: September 8, 2020 to September 28, 2020 (Suspended due to typhoon passing: September 16, 2022 to September 20, 2022) (2) Location: Livestock shed, Higashitaku, Taku City, Saga Prefecture (3) Capture method: (Test A) Sticky part of the insect trap sheet: 33cm x 30cm = approx. 0.1 square meters (Tests 1 to 9) The installation area of ​​the flying insect capture thread 1 and the flying insect capture net 2 is 0.1 square meters.

[0053] 3.Results At the start of the test, stable flies could not be seen entering the barn from the surrounding area. Normally, this would be the time of year when stable flies can be seen, but due to the effects of the typhoon, temperatures remained at around 35 degrees until September 15, 2022, which was presumably too high for stable flies to breed. After the typhoon passed on September 20, 2022, the temperature was about 30 degrees, which is a little high for stable fly occurrence, but the number of stable flies occurring is higher than before the typhoon passed. Nevertheless, the number of stable flies occurring during the survey period was lower than in previous years. The survey site and the surrounding area had been hit by flooding the year before the survey, so it is presumed that the stable fly breeding grounds were flooded, and the stable fly eggs and pupae were submerged and died.

[0054] Another factor that may affect the number of flying insects captured in the embodiment of the present application is a decrease in the adhesive strength of the adhesive part 2 due to the adhesion of sawdust to the adhesive part 2. The barn where the survey was conducted had sawdust spread on the floor as bedding for the livestock. Due to the high temperature during the test period, a large electric fan was rotating at high speed on the ceiling inside the barn, causing fine powder of sawdust to flow out from inside the barn to the outside. It is presumed that the fine powder of sawdust adhered to the adhesive part 2 of the installed flying insect capture thread 1, etc., causing the adhesive strength of the adhesive part 2 to decrease. During the survey period, the installed flying insect trapping thread 1, flying insect trapping net 2, and flying insect trap 4 were removed due to the passage of a typhoon. Most of the stable flies captured by the removed flying insect trapping thread 1, flying insect trapping net 2, and flying insect trap 4 had detached from the adhesive part 2 when removed, because the captured stable flies had dried after death. For this reason, it was not possible to know the number of captured stable flies at the time of removal, and the number of captured stable flies could not be counted when the traps were reinstalled after the typhoon had passed. Regarding the insect trapping sheet, since the entire body of the flying insect adheres to the adhesive part of the sheet, the captured flying insects did not detach when removed or reinstalled.

[0055] Table 1 shows data showing the number of stable flies captured. [Table 1]

[0056] Test A was a commercially available insect trapping sheet. Figures 9 and 10 show the adhesive sheets collected after this test. As shown in Figures 9 and 10, a wide variety of organisms were caught on the insect trapping sheet. Most of them were flies that were significantly larger than stable flies, including house flies, flesh flies, blow flies, blowflies, parasite flies, and crane flies. A total of 325 organisms were caught on the insect trapping sheet, of which about 20%, or just under 70, were stable flies. In all of Tests 1 to 9, the number of stable flies captured was greater than that captured by the insect trapping sheet, confirming the effectiveness of the present invention. Furthermore, in the test results, only stable flies whose entire bodies remained in the adhesive part 2 were counted, but when the adhesive part 2 was observed, countless legs were found to remain there. Figure 8 is an enlarged view of a part of the flying insect trapping net 2 that was collected after the investigation. It can be seen that only the legs of the stable flies are attached, without their heads or bodies. Unlike the insect trapping sheet to which the entire body of the stable fly adheres, the stable flies that adhere to the adhesive part 2 grab the flying insect trapping thread 1, the flying insect trapping net 2, and the thread 11 of the flying insect trap 4 with only their legs, so that the heads and bodies that dry out 4 to 5 days after death are blown off by the wind from the adhesive part 2, and only the legs remain on the adhesive part 2. In other words, the captured stable flies dry out after death and their heads and bodies peel off from the adhesive part 2, and more stable flies were actually caught than the number captured in the test results.

[0057] FIG. 7 shows the flying insect capture net 2 retrieved after test 5. As Tests 1 to 9 show, the number of stable flies caught exceeded that of the insect trapping sheet in all shapes, proving that stable flies are more likely to land on linear shapes than on surfaces. As shown in the capture situation of flying insect trapping net 2 in Figure 7, horseflies, black flies and other flies made up about 20% of the total, while 80% were stable flies, proving that stable flies prefer linear shapes. The test results are described in more detail below. In tests 1 and 2, five rows of flying insect trapping thread 1 were set up at intervals of 5 cm. In Tests 1 and 2, the flying insect trapping thread 1 was used as a single thread, and this was laid vertically and horizontally to compare the effect of laying it vertically and horizontally. Looking at the number of insects caught, the vertical laying (103 catches) was slightly less than the horizontal laying (151 catches), but this does not mean that the horizontal laying is generally more effective than the vertical laying. This is because the number of insects caught with the net in Tests 4 to 9 was almost the same for the vertical and horizontal laying.

[0058] In test 3, the thread 11 of the flying insect trapping thread 1 was twisted and stretched vertically, and the insect trapping members 3 were attached. The number of insects caught when the insect trapping members 3 were attached to the flying insect trapping thread 1 was tested. Multiple insect trapping members 3 were attached to the flying insect trapping thread 1 at intervals of 3 cm, and the short trapping threads 31 were 10 cm long. Test 3 (121 captures) had a somewhat higher capture number than Test 2. Also, many stable flies were observed to have detached from the adhesive part 2 of the capture part 3. Stable flies were more likely to adhere to the insect trapping member 3 in which the trapping thread 31 protrudes in a straight line from the flying insect trapping thread 1, compared to the insect trapping member 3 in which the trapping thread 31 hangs down along the flying insect trapping thread 1. This shows that it is desirable to configure the insect trapping member 3 so that the trapping thread 31 protrudes in a straight line from the flying insect trapping thread 1.

[0059] In tests 4 to 9, a flying insect trap net 2 with 10 cm square mesh was placed. Test 4 (180 catches), Test 5 (159 catches), Test 6 (195 catches), and Test 7 (165 catches) were conducted using black and yellow nets, and black and brown nets, respectively, to test the effect of different net colors on the number of catches. The test results showed that there was no significant difference in the number of stable flies caught depending on the net color, but if one had to specify a net color, black would be the best. Tests 4 and 6 compare the cases where the thread 11 is a single thread and a twisted thread. Tests 4 and 6 show that there is no difference in the number of insects caught, whether the thread 11 constituting the flying insect capture net 2 is a single thread or a twisted thread. If there is a difference in the number of insects caught, it is believed that this is due to a decrease in the adhesive strength of the adhesive part 2.

[0060] In Test 8 (160 captured insects) and Test 9 (162 captured insects), the insect catching members 3 were attached to the flying insect catching net 2. The insect catching members 3 were attached to the nodes of the flying insect catching net 2, and the short catching threads 31 were 10 cm long and made of twisted yarn. Because the trapping single yarns 31 are twisted yarns, many of the trapping short yarns 31 hang down along the flying insect trapping net 2, and as in the case of test 3, few stable flies adhered to the sticky parts of the insect trapping members 3. The reason why stable flies did not land on the insect trapping members 3 is thought to be that many of the trapping short yarns 31 hang down along the flying insect trapping net 2, which hinders the flight of the stable flies. Therefore, it cannot be concluded from the results of tests 8 and 9 that the insect trapping members 3 have no effect on trapping.

[0061] (Capture Test 2) 1. Purpose The flying insect trap 4 described in the fourth embodiment of the present invention will be tested for its flying insect trapping performance. 2. Method (1) Date and time: September 10, 2020 to September 15, 2020 (2) Location: Livestock shed, Higashitaku, Taku City, Saga Prefecture (3) Capture method: (Test 11, Test 12, Test 15) Installation area of ​​flying insect capture thread 1: 0.36 square meters (Test 13, Test 14) Installation area of ​​flying insect capture thread 1: 0.18 square meters

[0062] 3.Results Table 2 shows data showing the number of stable flies caught. [Table 2]

[0063] In this capture test 2, the flying insect trap 4 was placed inside the livestock barn. As mentioned above, the temperature was very high during the first half of the test period, and the large electric fan installed on the ceiling of the livestock barn was operating at high speed, so the fine powder of sawdust spread on the floor of the livestock barn was floating in the air, and when the flying insect trap 4 was removed on September 16, 2022, the adhesive parts of the flying insect capture thread 1 and the flying insect capture net 2 arranged on each frame part had fine sawdust powder attached to them, and the adhesive parts had lost their adhesiveness. For this reason, the number of stable flies captured by the flying insect trap 4 was not large. However, if the flying insect trap 4 is installed in a position where it is less affected by the fine sawdust powder or the adhesive strength of the adhesive parts is restored, it is expected that more stable flies will be captured.

[0064] In test 11, a flying insect capture net 2 was stretched twice (hereafter referred to as net A and net B) with single thread 11 and square mesh of 10 cm. When stretching the flying insect capture net 2 twice, the mesh positions of net A and net B were shifted by 5 cm vertically and horizontally, and a distance of 10 cm to 15 cm was set between net A and net B. Looking at the number of captured insects, there was no significant difference between net A (69 captured) and net B (63 captured). Test 12 (68 captures) and Test 13 (19 captures) were conducted to compare the effectiveness of vertical and horizontal installations, and the spacing between each flying insect capture line 1. In test 12, the thread 11 of the flying insect trapping thread 1 was used as a single thread or a twisted thread, and four threads were vertically strung at intervals of 3 cm, and five threads were vertically strung at intervals of 5 cm. In test 13, the thread 11 of the flying insect trap thread 1 was used as a single thread and a twisted thread, and seven threads were laid horizontally at intervals of 3 cm and four threads were laid horizontally at intervals of 5 cm. The number of flies caught in the horizontal installation in Test 13 was lower than that in the vertical installation in Test 12, but this is thought to be because the installation area in Test 13 was half that of Test 12 and the spacing of the flying insect capture lines 1 was 3 cm, which was too narrow for stable flies to pass through.

[0065] Test 14 (19 catches) and Test 15 (108 catches) were conducted to compare the effect of vertically and horizontally laying the flying insect trapping thread 1 equipped with the insect trapping members 3. In test 14, the thread 11 of the flying insect trapping thread 1 was made into a single thread, which was laid horizontally and had the insect trapping members 3 attached to it. A plurality of the insect trapping members 3 were attached to the flying insect trapping thread 1 at intervals of 3 cm, and the length of the short trapping thread 31 was 10 cm. In test 15, the thread 11 of the flying insect trapping thread 1 was laid horizontally as a single thread, and an insect trapping member 3 was attached to it. The number of insects caught when the insect trapping member 3 was attached to the flying insect trapping thread 1 was investigated. Multiple insect trapping members 3 were attached to the flying insect trapping thread 1 at 3 cm intervals, and the short trapping thread 31 was 10 cm long. The number of captured stable flies in Test 14 was lower than in Test 15, because the installation area in Test 14 was half that of Test 15. If we assume that the number of captured stable flies would also be half if the installation area in Test 15 was half, the number of captured stable flies in Test 15 was 54, which is half of 108, so there is no significant difference in the number of captured stable flies between the vertical and horizontal installation of the flying insect trapping thread 1 equipped with the insect trapping members 3.

[0066] Although the survey period for Tests 11 to 15 in Capture Test 2 was shorter than that of Capture Test 1, the number of captured stable flies exceeded that of Test A during the same period of Tests 1 to 9 (as of September 15, 2022), and the results were comparable to the number of captured flies in Tests 1 to 9. Therefore, the effect of the present invention can also be confirmed with the flying insect trap 4.

[0067] The above describes embodiments of the present invention's thread for capturing flying insects and net made from said thread. However, the present invention is not limited to the described embodiments, and various modifications can be made within the scope of the claims as long as they do not impair the object and effect of the present invention. In addition, although the invention described in this application uses an adhesive as a method for capturing flying insects, thread containing an insecticidal component in the adhesive may be used instead of the adhesive or in place of the adhesive.
