Description

[Technical Field]

[0001] The present invention relates to a pest trapping device and a method for trapping pests using the device. [Background technology]

[0002] Mosquitoes are a type of harmful insect that sucks the blood of humans and animals. Mosquitoes are attracted to the body heat of humans and animals, as well as the carbon dioxide exhaled through respiration. Taking advantage of this property, various devices have been proposed to attract, capture, or exterminate mosquitoes.

[0003] Regarding devices for capturing mosquitoes and other pests, known methods include those that use a black-colored object and a combination of heat or carbon dioxide to attract insects, and those that use a light source to attract insects. All of these technologies utilize the behavioral habits related to blood-sucking and foraging, and because they require heat or carbon dioxide generators or attractants, the devices tend to be complex, large, heavy, or expensive.

[Figure 7A-C] This is a perspective view from three directions showing a pest trapping device according to a second embodiment of the present invention. [Figure 8A-F] This figure shows an example of a tabletop according to the present invention. Each tabletop is configured so that the color gradually becomes lighter (brighter) from the edge of the opening toward the edge of the tabletop, through patterns or gradient effects using colors, lines, or designs. [Figure 9A-B] Figure 9A is a perspective view showing a modified insect trapping device according to the present invention, where the gray to black semicircular portion indicates an opening. Figure 9B shows an example of the installation of the device (installed on the underside of a table) in the insect trapping method of the present invention. [Modes for carrying out the invention]

[0010] The insect trapping device according to the present invention comprises a trapping container having a top plate with an opening formed therein that allows insects to enter, and a light-shielding plate erected on the top plate.

[0011] This configuration blocks light from entering the top panel by the light-shielding plate. As a result, a dark area is created on the top panel, meaning that the area around the opening is darker than the surrounding area, attracting pests that prefer dark places to the top panel. Furthermore, since the top panel of the capture container has an opening through which pests can enter, the pests can be attracted into the capture container and then captured inside.

[0012] Furthermore, the insect trapping device according to the present invention may be equipped with a means for suppressing the movement of insects, positioned substantially vertically inside the trapping container.

[0013] Pests (especially mosquitoes) have a habit of resting on vertical surfaces such as walls. Therefore, with this configuration, pests that enter through the opening will try to rest in contact with the restraining means, following their natural instinct. As a result, the movement of the pests is suppressed by the restraining means, keeping them inside the capture container and providing a highly effective pest capture device.

[0014] Furthermore, in the insect trapping device according to the present invention, the light-shielding plate may be erected at an angle of approximately 15 degrees to approximately 90 degrees relative to the top plate.

[0015] This configuration ensures that the light-shielding plate does not block the opening, and that it covers the top plate and the opening from the inside of the container outwards. As a result, light attempting to enter the top plate and the opening is blocked by the light-shielding plate, making part of the top plate, the opening, and the inside of the capture container dark. Since pests have a tendency to gather in dark places rather than bright places, this configuration utilizes this mosquito behavior to attract mosquitoes into the container, thus providing a more effective pest capture device.

[0016] Furthermore, the opening in the insect trapping device according to the present invention may be provided so as to be in contact with at least a part of the edge of the top plate, and the light-shielding plate connecting portion that supports the light-shielding plate may also be provided so as to be in contact with the said edge.

[0017] This configuration creates a light-shielding plate connection section that supports the opening and the light-shielding plate so as to be in contact with the edge of the top plate, thus allowing the opening and the light-shielding plate to be placed in close proximity. As a result, the light-shielding plate can more effectively block light from entering the top plate, opening, and inside the capture container, attracting more mosquitoes into the container and thus capturing more pests.

[0018] Furthermore, the insect trapping device according to the present invention can have a top plate that is black or red in color.

[0019] This configuration attracts more pests into the trapping container, allowing for the capture of a larger number of pests.

[0020] Furthermore, the top plate of the insect trapping device according to the present invention may be colored to have a gradient, that is, a gradient of light and dark. In this case, the gradient may be applied so that it gradually becomes lighter from the edge of the opening toward the edge of the top plate, or in the opposite direction.

[0021] This configuration creates a gradient of colors, gradually darkening from the edge of the top panel towards the edge of the opening and the inside of the capture container. As a result, it is possible to attract pests that prefer dark places towards the inside of the capture container, thus capturing more pests.

[0022] Furthermore, the insect trapping device according to the present invention has an opening area of ​​approximately 4 cm². 2 Approximately 144cm 2 The following applies, and the shape of the opening can be approximately circular or approximately rectangular.

[0023] This configuration prevents objects other than the target pests from entering the capture container through the opening, and also allows the pest capture device to be installed in confined spaces.

[0024] Furthermore, the targets of the insect trapping device according to the present invention can be insects or flying insects, particularly flying insects such as mosquitoes, flies, and moths.

[0025] The present invention relates to a pest capture method in which a pest capture device is placed in a location where pests may be present, comprising a capture container having a top plate with an opening formed therein that allows pests to enter, and a light-shielding plate erected on the top plate, allowing pests to enter through the opening and capture inside the capture container.

[0026] The first embodiment of the present invention will be described in detail below with reference to the attached drawings. In the following description, the vertical direction is defined based on the state in which the insect trapping device 10 according to the embodiment of the present invention is installed on a flat surface (the state shown in Figure 4). The front-to-back direction is defined with the left side of the paper in Figure 4 as the front side of the insect trapping device 10. The left-to-right direction is defined when viewing the insect trapping device 10 in Figure 2 from the front.

[0027] Figure 1 is a perspective view of the insect trapping device 10. Figure 2 is a front view of the insect trapping device 10. As shown in these figures, the insect trapping device 10 has a trapping container 12 and a light-shielding plate 14 provided on top of it.

[0028] (Capture container) First, let's describe the capture container 12. As shown in Figure 1, the capture container 12 consists of a total of six surfaces: one top plate 16, four side walls 18, and one bottom wall 20, each surface being rectangular in shape. The shape of the capture container 12 is not limited, as long as it can capture pests inside the container 12. For example, it may be a cylindrical or nearly cylindrical shape formed by a circular top plate, bottom wall, and side walls, or a polyhedron other than a hexahedron formed by a polygonal top plate and bottom wall, and side walls with the same number of sides as the polygon, or it may be a hemispherical shape with the top plate, side walls, and bottom wall integrated into one. The material of the capture container 12 is not particularly limited, but can be selected from various materials such as paper, cardboard, nonwoven fabric, cloth, plastic, metal, and wood.

[0029] The size of the capture container 12 is not particularly limited and can be adjusted as appropriate depending on the size of the pest to be captured and the location where the pest capture device 10 is installed. For example, when intended for indoor use, it can be a box with dimensions of approximately 8 to 35 cm in the left-right direction (width), approximately 8 to 20 cm in the front-back direction (width), and approximately 5 to 20 cm in the up-down direction (height). When intended for outdoor use, for example, it is desirable that the left-right direction (width), front-back direction (width), and up-down direction (height) are all 30 cm or more. The size can be adjusted as appropriate depending on the size of the pest to be captured and the location where the pest capture device is installed.

[0030] (Top plate) The top plate 16 of the capture container 12 will be described. As shown in FIG. 1, the top plate 16 is provided on one surface of the capture container 12. Further, a light shielding plate connection portion 30 for installing a light shielding plate 14 described later is formed at an edge portion 22 of the top plate 16. In the present specification, the “edge portion” means a ridge line formed by contact between surfaces.

[0031] The top plate 16 has a rectangular opening 24 through which pests can enter. The shape of the opening 24 is not particularly limited as long as pests can enter the inside of the capture container 12. For example, it can be rectangular, polygonal, substantially arc-shaped, or star-shaped. Note that the top plate can be made larger than the area of the top surface of the capture container (the surface formed by the sides in the front-rear direction and the left-right direction of the capture container), as shown in FIG. 5A for example.

[0032] The area of the opening 24 can be, for example, about 4 cm 2 or more. The diameter when a mosquito spreads its wings is about 1.5 cm. Therefore, if the minimum width of the opening 24 is about 1.5 cm and the area is about 4 cm 2 or more, small pests such as mosquitoes can enter the inside of the capture container 12 through the opening 24. Also, the area of the opening 24 can be about 144 cm 2 or less. By setting the area of the opening 24 to about 144 cm 2 or less, the size of the capture container 12 can be reduced, and the pest capture device 10 can be installed in a narrow space. Note that the size of the opening 24 can be about 4 cm 2 or more, about 16 cm 2 or more, or about 36 cm 2 or more, and about 144 cm 2 or less, about 100 cm 2 or less, about 81 cm 2 or less, or about 64 cm 2 or less. Among these, about 4 cm 2 ~about 81 cm 2The following are considered preferable sizes. Furthermore, if the opening is roughly rectangular, the length and width can be approximately 2 x 2 cm, 4 x 4 cm, 9 x 2 cm, 9 x 9 cm, or 9 x 15 cm.

[0033] The opening 24 in the tabletop 16 is positioned approximately in the center in the left-right direction, and is formed such that a portion of the edge 22 forming one of the rear edges of the tabletop touches the edge 26 forming one of the rear edges of the opening 24. However, the position of the opening 24 is not limited to this. For example, it may be formed approximately in the center of the tabletop 16 in both the left-right and front-to-back directions (near the center of the tabletop), or in a part of the tabletop closer to the center than the edge. The number of openings is not limited to one or more.

[0034] The top plate 16 may have color applied to at least a portion of it. Here, "color" refers to any color other than transparent, including white and black, and includes colors applied in the form of lines or patterns. The color may be applied to the entire top plate. The color may also be applied in a single shade or in a gradient. The color can be one or more selected from black, red, blue, and green, or one or more selected from black and red. Among these, black or red are preferred because they allow for the capture of more pests.

[0035] The color of the top panel 16 may form a pattern. Patterns formed by the color include patterns and designs made of lines of black or other colors, patterns and designs made of color alone, patterns and designs made of color and lines, and patterns composed of color, lines, and designs. The pattern may also be applied in a way that creates a gradient effect using lines and designs.

[0036] Here, "gradation" means that the shade and / or brightness of a color changes gradually. For example, the color may be applied so that it gradually becomes lighter from the edge of the opening 24 towards the edge of the top plate 16, or so that the brightness of the color increases continuously. "Applied in a way that gradually fades" means, for example, that the color is applied so that the hue changes continuously, or that the density of a pattern such as dots or stripes is gradually reduced from near the edge of the opening 24 towards the edge of the top plate 16, thereby forming a color and pattern that appears to increase in brightness continuously.

[0037] (side wall) The side wall 18 will now be described. As shown in Figure 1, the side wall 18 is formed by connecting along the edge 22 of the top plate 16 all the way around. Also in Figure 1, the side wall 18 is composed of four surfaces, the first to the fourth side portions, corresponding to each side of the top plate 16. Note that, as shown in Figure 5A, the side wall 18 does not need to be formed along the edge 22 of each side of the top plate 16, and may be formed from the part of the top plate 16 closer to the center (near the edge) from the edge. That is, as shown in Figure 5A, the top plate 16 may be formed to protrude from the side wall 18 in the front-rear direction and / or left-right direction.

[0038] The inner side surface of the side wall 18 of the capture container 12 is provided with a means to suppress the movement of pests, although this is not shown in the diagram. Flying pests such as mosquitoes, which will be described later, have a habit of resting on vertical walls and other surfaces. Therefore, if the suppression means is provided on the inner side surface of the side wall 18 of the capture container 12 so as to be approximately vertical when the pest capture device is installed, pests that enter the capture container 12 will try to use the suppression means to rest due to their habit. As a result, the movement of the pests is suppressed by the suppression means, and the pests can be captured while remaining on the suppression means. The suppression means may also be provided inside the capture container 12 other than on the inner side surface of the side wall 18 of the capture container 12. Such a suppression means is not particularly limited as long as it is a means capable of capturing pests, but for example, a substrate coated with an adhesive substance such as an adhesive agent, or an adhesive sheet can be used. When using an adhesive agent or adhesive sheet, it is possible to use one that has adhesive properties that can capture the target pests. For example, in the inclined ball tack test method specified in JIS Z 0237, it is desirable that the material has sufficient adhesiveness to stop balls with a ball number of 12 (3 / 8 inch) or larger.

[0039] Alternatively, insecticides that kill or injure pests can be used as a means of suppression other than adhesives or sticky sheets. The insecticide can be appropriately selected depending on the type of pest to be captured. Furthermore, although the present invention is characterized by capturing pests without using attractants, attractants may be used to attract and capture pests if necessary. In addition, sugar water or the like can be placed inside the capture container to serve as food or water for the target pests, or the humidity inside can be increased to further enhance the attractiveness.

[0040] (Bottom wall) Let's describe the bottom wall 20. As shown in Figure 1, the bottom wall 20 is formed by connecting along the lower edges of each of the four side walls 18.

[0041] A restraining means (not shown) may be erected inside the capture container 12 so as to be substantially perpendicular to the bottom wall 20, that is, substantially perpendicular within the capture container 12. This allows the restraining means to be installed inside the capture container 12 in addition to the side wall 18 on the side facing the capture container 12, thereby providing a pest capture device 10 that can capture more pests. Furthermore, if it is difficult for the restraining means to maintain its position independently inside the capture container 12, a support portion for the restraining means can be provided on the inside of the bottom wall 20, and the restraining means can be installed via this support portion.

[0042] (Light-blocking plate) The light-shielding plate 14 will now be described. The shape of the light-shielding plate 14 may be rectangular, roughly rectangular, circular, roughly circular, triangular, polygonal, or other shapes. Alternatively, as shown in Figures 1 to 4, it can be made into a rectangle with notches at the four corners, and the edges of the light-shielding plate can be folded using the notches to cover the opening. As shown in Figures 3 and 4, the light-shielding plate 14 is formed on the top plate 16 at the light-shielding plate connection part 30. In Figure 1, a part of the edge 26 of the opening is provided so as to coincide with a part of the edge 22 of the top plate and the light-shielding plate connection part 30. As another configuration of the opening and the light-shielding plate connection part, for example, if the opening is provided closer to the center of the top plate and not in contact with the edge of the top plate, the light-shielding plate connection part can be provided on a part of the edge of the opening, or the light-shielding plate connection part can be provided on the edge of the top plate, and the light-shielding plate can be formed so that the light-shielding plate covers the opening from the light-shielding plate connection part. The light-shielding plate connection point may be located on the edge of the top plate, or on a portion of the top plate closer to the center than the edge, or on the edge of the opening, or closer to the edge of the top plate than the edge of the opening. Regardless of the position of the light-shielding plate connection point and the opening, by arranging the light-shielding plate to cover the opening, the light-shielding plate 14 can block light from the surface side of the light-shielding plate 14 into the top plate, the opening, and the inside of the capture container. This has the effect of attracting mosquitoes and other pests into the capture container 12, allowing for the capture of more pests.

[0043] In Figures 2 and 3, the light-shielding plate 14 is erected so that its length in the left-right direction is approximately the same as the length in the left-right direction of the capture container 12. The length of the light-shielding plate 14 in the left-right direction is not limited to this; it may be approximately the same as the length in the left-right direction of the opening 24, or it may be longer than the length in the left-right direction of the capture container 12. That is, the light-shielding plate 14 may be erected so as to cover the top of both the top plate 16 and the opening 24, or it may be erected so as to cover the top of the opening 24.

[0044] The material of the light-shielding plate 14 is not particularly limited, but can be selected from a variety of materials such as paper, cardboard, nonwoven fabric, cloth, plastic, metal, and wood.

[0045] As shown in Figure 4, the light-shielding plate 14 is erected on the light-shielding plate connection part 30 so as to form an angle (θ) 40 with respect to the top plate 16. The angle (θ) 40 can be approximately 15 degrees or more, approximately 30 degrees or more, or approximately 45 degrees or more, and approximately 90 degrees or less, approximately 80 degrees or less, or approximately 60 degrees or less. Among these, approximately 45 degrees is a preferred angle.

[0046] The shape of the light-shielding plate 14 is not limited to a rectangle; it may also be a polygon, and its sides may be approximately circular arcs. Alternatively, for example, a cutout in the top plate 16 may be made, leaving some of its sides intact (e.g., a U-shape), and a portion of the top plate 16 may be cut upwards to form an opening 24, while the cut portion of the top plate 16 is formed to become the light-shielding plate 14. With this configuration, the opening 24 is not yet formed when transporting the insect trapping device 10, and the opening 24 can be formed when using the insect trapping device 10, thus providing an insect trapping device 10 that is easy to transport.

[0047] In addition, similar to how the top plate 16 is colored, one or more colors selected from black, red, blue, and green may be applied to the inner or outer surface of the light-shielding plate 14 of the capture container 12, or patterns or designs may be applied to the top plate 16 in the same way that patterns or designs are drawn on the top plate 16, or colors may be applied to the top plate 16 in a gradient manner, gradually fading from the edge of the opening 24 towards the edge of the top plate 16, similar to how colors are applied to the top plate 16 in the same way that from the edge of the opening 24 towards the edge of the top plate 16.

[0048] Furthermore, the insect trapping device of this embodiment targets insects or flying insects. "Flying insects" refers to mosquitoes, flies, moths, etc. Specifically, this includes mosquitoes such as Culex pipiens, Culex tritaeniorhynchus, and Culex atropurosa, as well as Anopheles mosquitoes such as Anopheles sinensis and Anopheles japonica, Aedes albopictus and Aedes aegypti, houseflies and drain flies, moths such as Pyralidae, midges, or booklice (winged and wingless). Among these, the preferred target is mosquitoes.

[0049] A second embodiment of the present invention, a pest trapping device 70, will be described with reference to Figures 7A to 7C. The pest trapping device 70 comprises a trapping container 72 having an opening 74 into which pests can enter, and a structure capable of forming a space S where the area around the opening is darker than the surroundings. The opening 74 is provided in the top plate 76, and the side walls 78 are provided on three sides so as to surround the top plate 76. That is, the trapping container 72 is formed by the top plate 76, three side walls 78, and a bottom wall 80, and in this case the top plate 76 and the bottom wall 80 are in contact at the edge 82 of the top plate. As shown in Figure 7B or Figure 7C, when the pest trapping device 70 is installed on the floor or the like with the bottom wall 80 facing upwards, the two opposing side walls 78 and the top plate 76 can form a space S that is darker than the surroundings, even without the light-shielding plate of the first embodiment. Furthermore, if the shape of the capture container is a polyhedron such as a star-shaped polyhedron, a darker space than the surroundings can be created even without a top plate; therefore, in the second embodiment, a top plate is not essential.

[0050] (How to capture pests) Furthermore, the pest capture method according to the embodiment of the present invention is a method of capturing pests using the pest capture device described above. Specifically, the pest capture device can be installed in areas where pests are likely to be present, such as rooms, in places where pests are likely to enter, by hanging it on a wall, or outdoors on a balcony, etc., in any place where pests are likely to be present, whether indoors or outdoors. Alternatively, as shown in Figure 9B, the side wall of the capture container can be attached to the underside of a desk or table using double-sided tape, magnets, etc. When installing the pest capture device, the light-shielding plate should be positioned on the side where light enters the installation location. By installing it in this way, the effect of the light-shielding plate can be efficiently exerted. [Examples]

[0051] The present invention will be described in detail below with reference to examples, but the present invention is not limited in any way by these examples.

[0052] (Example 1) As Example 1, a pest trapping device 50 having a trapping container 52 and a light-shielding plate 54 as shown in Figure 5A was created. Figure 6A shows a top view of the pest trapping device 50 of Example 1 with the top plate 56 removed. The trapping container is made of paper and measures 18 cm in the front-to-back direction, 33 cm in the left-to-right direction, and 10 cm in the up-to-down direction. The light-shielding plate 54 is also made of paper and is a rectangular plate measuring 33 cm (flat portion) in the left-to-right direction and 10 cm in the front-to-back direction, formed to stand upright from the rear edge of the top plate 56 at a 45-degree angle to the top plate 56. The opening 64 is located approximately in the left-to-right center of the top plate, and the top plate is cut out from the rear edge 62 of the opening to measure 9 cm in the front-to-back direction and 9 cm in the left-to-right direction. The top plate 56 was made of colored paper with a black edge 66 at the opening, a white area near the edge 62 of the top plate, and a gradient of colors that gradually lightened from black to gray from the edge 66 of the opening towards the edge 62 of the top plate. As a means of suppression, two 8cm x 16cm adhesive sheets (manufactured by Hozu Shoji Co., Ltd., the same applies hereafter) were attached to the two side walls facing each other in the front-to-back direction inside the capture container 52 using double-sided tape, and two 8cm x 10cm adhesive sheets were attached to the two side walls facing each other in the left-to-right direction.

[0053] (Example 2) The insect trapping device 50 was constructed in the same manner as in Example 1, except that the top plate 56 was cut out to create an opening 64 with dimensions of 9 cm in the front-to-back direction and 2 cm in the left-to-right direction.

[0054] (Example 3) Aside from cutting out the top plate 56 to create an opening 64 with dimensions of 9 cm in the front-to-back direction and 15 cm in the left-to-right direction, the insect trapping device 50 was constructed in the same manner as in Example 1.
