Summary of the Invention

Problems to be Solved by the Invention

[0004] <s In the insect trap described in Patent Document 1, when continuously capturing insects for a long time, in addition to the adhesive sheet, the attractant also needs to be replaced regularly. Therefore, when using a plurality of insect traps in a farm or the like, maintenance such as replacing the attractant for all the insect traps becomes a great deal of trouble. For this reason, in many farms, a primitive method of simply hanging the adhesive sheet around the crops is used.

[0005] In such a primitive method, although the maintenance work is simple, there is a problem that the adhesive sheet sticks to the crops as the crops grow. On the other hand, if the adhesive sheet is placed at a position away from the crops so as not to stick to the crops, there is a problem that the insect-catching effect of the insects gathering on the crops is reduced.

[0006] This invention has been made in view of these circumstances, and aims to provide a technology that can prevent sheet-like insect trapping members from sticking to crops. [Means for solving the problem]

[Brief explanation of the drawing]

[0030] [Figure 1] This is a perspective view of an insect trap according to one embodiment. [Figure 2] This figure shows how an insect trap according to one embodiment works in use. [Figure 3] This is a perspective view of an insect trap according to one embodiment. [Figure 4] This is a perspective view of an insect trap according to one embodiment. [Figure 5] This is a cross-sectional view of an insect trap according to one embodiment. [Figure 6] This figure shows an example of the arrangement of an insect trap according to one embodiment. [Modes for carrying out the invention]

[0031] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0032] <1. First Embodiment> Figure 1 is a perspective view of an insect trap 1 according to one embodiment. Figure 2 shows the insect trap 1 in use. Figures 3 and 4 are perspective views of the insect trap 1 in the open state. Figure 5 is a cross-sectional view of the insect trap 1.

[0033] The insect trap 1 is a device for capturing flying insects (hereinafter simply referred to as "insects") using a sheet-like adhesive material 9. As shown in Figure 1, the insect trap 1 has a main body 10 and a retaining tape 20. The main body 10 is attached to the retaining tape 20. The adhesive material 9 is held inside the main body 10.

[0034] As shown in Figure 2, the insect trap 1 can have multiple main body parts 10 attached to a single holding tape 20. In Figure 2, the insect trap 1 is positioned above multiple crops 82 planted in a furrow 81. When the main body parts 10 of the insect trap 1 are positioned above the crops 82 in this way, the crops 82 grow upward as they grow. At this time, if the adhesive member 9 is exposed, a problem arises in which the crops 82 will stick to the adhesive member 9. In this insect trap 1, the cover 30 covers the adhesive member 9, thereby preventing the crops 82 from sticking to the adhesive member 9.

[0035] In the following, the vertical direction is defined with respect to the connecting portion 40 of the main body 10, with the cover 30 and fixing portion 50 being on the lower side. The direction perpendicular to the vertical direction is referred to as the horizontal direction. Within the horizontal direction, the direction in which the cover 30 extends is referred to as the front-to-back direction, and the direction perpendicular to the front-to-back direction is referred to as the left-to-right direction. This definition of direction does not limit the posture in which the insect trap is used.

[0036] The main body 10 includes a cover 30, two connecting parts 40, and a fixing part 50. The main body 10 consists of a first member 11 and a second member 12 formed symmetrically in the left-right direction. The first member 11 constitutes the right half of the main body 10. The second member 12 constitutes the left half of the main body 10. Therefore, the first member 11 and the second member 12 each include half of the cover 30, half of each connecting part 40, and half of the fixing part 50. In this embodiment, the main body 10 is integrally molded from resin. The lower end of the first member 11 and the lower end of the second member 12 are connected.

[0037] Thus, because the main body 10 has a symmetrical shape, it can be handled in the same way from either the left or the right. Therefore, when attaching multiple main body units 10 in a field, or when replacing the adhesive members 9 on multiple main body units 10, the work can be done without considering the left or right orientation.

[0038] When the insect trap 1 is in use, the main body 10 is used in a closed state, as shown in Figure 1, with the first member 11 and the second member 12 closed so that they are symmetrical. Also, when the insect trap is in use, the adhesive member 9 is attached to the fixing part 50 in a position that is aligned with a plane extending in the vertical and front-to-back directions. When attaching the adhesive member 9 inside the main body 10 or when replacing the adhesive member 9, the first member 11 and the second member 12 of the main body 10 can be opened, as shown in Figures 3 and 4.

[0039] The cover 30 is a housing with an internal space. Inside the cover 30, there is a fixing part 50 for securing the adhesive member 9. When the adhesive member 9 is attached to the fixing part 50, the cover 30 covers the adhesive member 9. Hereafter, the state in which the adhesive member 9 is attached to the fixing part 50 and the cover 30 is closed will be referred to as the "usage state".

[0040] As shown in Figures 1 and 3 to 5, the cover 30 has an upper cover portion 31, a pair of left and right side cover portions 32 and 33, and a pair of front and rear end cover portions 34 and 35. The cover 30 has through holes 300 in most of its area. The through holes 300 are large enough for the insects to be captured to pass through.

[0041] The upper cover portion 31 is positioned above the fixing portion 50 and covers the upper part of the fixing portion 50. In other words, in the state of use, the upper cover portion 31 is positioned above the adhesive member 9 and covers the upper part of the adhesive member 9.

[0042] The upper cover portion 31 has a light-shielding portion 311 near the center in the left-right direction. The light-shielding portion 311 does not have a through hole 300. As a result, the light-shielding portion 311 can block a portion of the light that goes from above the upper cover portion 31 toward the fixing portion 50. In other words, the light-shielding portion 311 can block a portion of the light that goes from above the cover 30 toward the adhesive member 9 fixed to the fixing portion 50. By creating a contrast between light and shadow on the adhesive member 9, the insect-catching effect can be improved.

[0043] The pair of side cover portions 32 and 33 extend downward from the left and right ends of the upper cover portion 31, respectively. Here, the right side cover portion 32 is referred to as the right side cover portion 32, and the left side cover portion 33 is referred to as the left side cover portion 33. In this embodiment, the lower ends of the left and right side cover portions 32 and 33 are connected.

[0044] The right-side cover portion 32 is positioned to the right of the fixing portion 50. In use, the right-side cover portion 32 covers the right-side surface of the adhesive member 9. The right-side cover portion 32 has a first right-side cover portion 321 and a second right-side cover portion 322. The left-side cover portion 33 is positioned to the left of the fixing portion 50. In use, the left-side cover portion 33 covers the left-side surface of the adhesive member 9. The left-side cover portion 33 has a first left-side cover portion 331 and a second left-side cover portion 332.

[0045] The first right-side cover portion 321 extends downward from the right end of the upper cover portion 31. The first left-side cover portion 331 extends downward from the left end of the upper cover portion 31. The first right-side cover portion 321 and the first left-side cover portion 331 are arranged approximately parallel to each other with a gap between them in the left-right direction.

[0046] The second right cover portion 322 extends downward and to the left from the lower end of the first right cover portion 321. The second left cover portion 332 extends downward and to the right from the lower end of the first left cover portion 331. The second right cover portion 322 and the second left cover portion 332 are connected at their lower ends. As a result, as shown in Figures 1 and 5, the second right cover portion 322 and the second left cover portion 332 constitute a lower cover portion 36 that extends in the front-rear direction below the fixing portion 50. The lower cover portion 36 tapers downward when viewed in the front-rear direction.

[0047] The pair of end cover portions 34 and 35 are positioned at the front-rear ends of the cover 30, respectively. Here, the front end cover portion 34 is referred to as the front end cover portion 34, and the rear end cover portion 35 is referred to as the rear end cover portion 35. In use, the front end cover portion 34 covers the front of the adhesive member 9. The rear end cover portion 35 covers the rear of the adhesive member 9 in use.

[0048] The connecting portion 40 is a part that can be attached to a tape or string. In this embodiment, the connecting portion 40 is attached to the retaining tape 20. The connecting portion 40 is positioned above the cover 30 and the fixing portion 50. The connecting portion 40 extends upward from the upper end of the cover 30. This allows the main body 10 to be suspended from the retaining tape 20.

[0049] The two connecting parts 40 are positioned with a gap between them in the front-to-back direction. Having two connecting parts 40 makes it difficult for the main body 10 to tilt relative to the retaining tape 20.

[0050] Specifically, as shown in Figure 5, the connecting portion 40 has a first neck portion 41 and a first C-shaped portion 42 belonging to the first member 11, and a second neck portion 43 and a second C-shaped portion 44 belonging to the second member 12. The first neck portion 41 and the second neck portion 43 extend upward from the upper surface of the upper cover portion 31. The first C-shaped portion 42 is positioned above the first neck portion 41. The second C-shaped portion 44 is positioned above the second neck portion 43. The first C-shaped portion 42 is C-shaped with a recess to the left when viewed in the front-to-back direction. The second C-shaped portion 44 is C-shaped with a recess to the right when viewed in the front-to-back direction.

[0051] When the cover 30 is closed, the first C-shaped portion 42 and the second C-shaped portion 44 come into contact, forming a cylindrical shape that extends forward and backward. When closing the cover 30 from the open position before use, the connecting portion 40 can be connected to the retaining tape 20 by inserting the retaining tape 20 between the first C-shaped portion 42 and the second C-shaped portion 44.

[0052] The fixing portion 50 is a part to which the adhesive member 9 can be attached. In this embodiment, the fixing portion 50 has two first protrusions 51 included in the first member 11 and two second protrusions 52 included in the second member 12.

[0053] The first projection 51 extends from the right cover portion 32 to the left. The second projection 52 extends from the left cover portion 33 to the right. The left end of the first projection 51 and the right end of the second projection 52 face each other in the left-right direction with a gap in between.

[0054] The first projection 51 and the second projection 52 are both plate-shaped and perpendicular to the front-to-back direction. That is, the first projection 51 and the second projection 52 are plate-shaped and extend in the left-to-right direction. As a result, the area of ​​the left end of the first projection 51 and the right end of the second projection 52 facing the adhesive member 9 is small. This reduces the contact surface between the fixing part 50 and the adhesive member 9. Therefore, the adhesive surface of the adhesive member 9 that has an insect-catching effect can be made larger. Note that the first projection 51 and the second projection 52 are not limited to plate-shaped, but may also be pin-shaped (thin columnar) extending in the left-to-right direction. Even in that case, the contact surface between the fixing part 50 and the adhesive member 9 can be reduced.

[0055] When using the insect trap 1, the adhesive member 9 is attached to the left end of the two first protrusions 51, as shown in Figure 3. Then, by closing the cover 30, the second protrusion 52 is positioned along the right side surface of the adhesive member 9. In this way, the adhesive member 9 is sandwiched from both sides by the first protrusions 51 and the second protrusions 52, which prevents the adhesive member 9 from shifting in the left-right direction.

[0056] In this embodiment, both of the two first protrusions 51 face the second protrusions 52 in the left-right direction, but the present invention is not limited to this. When the cover 30 has multiple first protrusions 51 and multiple second protrusions 52, not all of the first protrusions 51 face the second protrusions 52, and only some of the first protrusions 51 face the second protrusions 52.

[0057] Thus, the main body 10 has a lower cover portion 36 that covers the area below the adhesive member 9. This prevents the crop 82 from sticking to the adhesive member 9 even if the crop 82 grows upward when the adhesive member 9 is placed above the crop 82.

[0058] In particular, the lower cover portion 36 is V-shaped when viewed in the front-to-back direction. That is, the lower cover portion 36 is shaped to narrow downwards when viewed in the front-to-back direction. This makes it easier for the crop 82 to grow along both sides of the lower cover portion 36 as it grows and comes into contact with the lower cover portion 36 before continuing to grow upwards. The lower cover portion 36 may also be U-shaped when viewed in the front-to-back direction. In that case as well, the crop 82 will still easily grow along both sides of the lower cover portion 36 after coming into contact with it.

[0059] In this embodiment, the cover 30 has a first right-side cover portion 321 and a second left-side cover portion 332 above the lower cover portion 36. In this way, the right-side cover portion 32 and the left-side cover portion 33 cover both sides of the adhesive member 9, so that even if the crop 82 grows above the lower cover portion 36, it is possible to prevent the crop 82 from sticking to the adhesive member 9.

[0060] The retaining tape 20 is a tape-shaped portion for holding the main body 10. Although the retaining tape 20 is a tape-shaped member, the main body 10 may also be held by a string-shaped member. As shown in Figure 5, the retaining tape 20 has a tape body 21 and a plurality of light sources 22. The tape body 21 is a tape-shaped member formed of cloth, resin, or the like. Each of the plurality of light sources 22 is attached to the lower surface of the tape body 21. That is, the plurality of light sources 22 are arranged on the lower surface of the retaining tape 20.

[0061] The multiple light sources 22 are LED light sources. The light sources 22 are positioned on the retaining tape 20 where the main body 10 is attached. One light source 22 may be placed for each main body 10, or multiple light sources 22 may be placed for each main body 10. For example, five light sources 22 may be placed between two connecting parts 40 with gaps in between.

[0062] In this way, the light emitted from the light source 22 spreads around the main body 10. As a result, insects attracted by the light emitted from the light source 22 gather around the cover 30. At this time, insects that enter the inside of the cover 30 through the through-hole 300 are captured by the adhesive material 9. This makes it possible to exterminate insects.

[0063] Figure 6 shows an example of the arrangement of the insect trap 1. Figure 6 shows an example of the arrangement of the furrows 81 and the insect trap 1 inside the greenhouse 80. In the example in Figure 6, a power supply 100, a retaining tape 20, and six main body units 10 are arranged for each of the four furrows 81.

[0064] The retaining tape 20 has one or more light sources 22 at each position where the main body portion 10 is attached. That is, in the example of Figure 6, one retaining tape 20 has one or more light sources 22 at the eight locations where the eight main body portions 10 are each positioned.

[0065] In the example shown in Figure 6, the multiple light sources 22 include multiple first light sources with a first wavelength as the central wavelength, and multiple second light sources with a second wavelength as the central wavelength. The second wavelength is different from the first wavelength. By using light of two or more wavelength bands in this way, the variety of insects that can be attracted increases. This allows for efficient insect attraction.

[0066] In the example shown in Figure 6, the retaining tape 20 has three first positions P1 and three second positions P2 where the main body 10 is positioned. The first positions P1 and the second positions P2 are arranged alternately. A first light source is positioned at the first positions P1 of the retaining tape 20. A second light source is positioned at the second positions P2 of the retaining tape 20. As a result, insects that are easily attracted by the first wavelength gather at the main body 10 positioned at the first positions P1. In addition, insects that are easily attracted by the second wavelength gather at the main body 10 positioned at the second positions P2.

[0067] In this embodiment, the first wavelength is a wavelength in the green wavelength band between 495 nm and 570 nm. This first wavelength of light can efficiently attract insects such as the southern flower thrips, tea yellow thrips, onion thrips, tobacco whiteflies, long-toothed fungus gnats, and brown marmorated stink bugs.

[0068] Furthermore, the second wavelength is in the near-ultraviolet UV-A wavelength band, ranging from 315 nm to 380 nm. This second wavelength of light can efficiently attract insects such as the citrus thrips, tea thrips, onion thrips, tobacco whiteflies, fungus gnats, black-legged leafminers, fruit flies, and brown marmorated stink bugs.

[0069] In the example shown in Figure 6, one type of light source is arranged around one main body 10, but the present invention is not limited to this. Multiple types of light sources may be arranged around each main body 10.

[0070] <2. Variant> Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment.

[0071] In the above embodiment, the main body 10 is attached to a holding tape 20 having a light source 22. However, the main body 10 may be attached to a tape or string that does not have a light source.

[0072] In the above embodiment, the connecting portion 40 had a structure in which the tape or string was surrounded by a cylindrical portion composed of two members. However, the connecting portion 40 may have other structures as long as it can be connected to the tape or string. The connecting portion 40 may be, for example, hook-shaped.

[0073] In the above embodiment, as shown in Figure 1, the through holes 300 provided in the upper cover portion 31 and the side cover portions 32 and 33 of the cover 30 were rectangular in shape. However, the through holes 300 may be any shape, such as triangular, square, or hexagonal.

[0074] Furthermore, the detailed configuration of the insect trap may differ from the shapes shown in the figures of this application. In addition, the elements that appear in the above embodiments and modifications may be combined as appropriate, to the extent that no inconsistencies arise. [Explanation of Symbols]
