Description

[Technical Field]

[0001] The present invention relates to an insect trap for capturing harmful insects that infest agricultural crops, and more particularly to a box-shaped insect trap made of paper or the like that can be easily assembled. [Background technology]

[0002] In agricultural greenhouses, fields, orchards, floriculture farms, and other farms, measures are taken to protect crops from tiny pests such as whiteflies and thrips, as well as relatively large pests such as flies and aphids, by suspending sticky insect trapping sheets around the vegetation. These insect trapping sheets are also used to survey the habitat of pests on farms.

[0003] However, hanging insect traps look unsanitary when they are filled with a large number of pests. Furthermore, because the adhesive surface of the insect trap is exposed to the outside, any crops that come into direct contact with the adhesive surface will be damaged and lose their market value. Therefore, insect traps cannot be placed in close proximity to crops, such as between the leaves or in the gaps between crops, where more pests live than in the surrounding vegetation. Furthermore, agricultural production requires the application of fertilizer and pesticides and watering (except for hydroponics). If fertilizer or water (liquid fertilizer, pesticides, water) gets on the exposed adhesive surface of the insect trap, its adhesive strength will decrease, and the insect trap must be replaced.

[0004] Instead of such hanging insect trapping sheets, various box-shaped insect traps that can be installed on farms have also been considered. Examples of such insect traps include a flying pest trapping device that is installed in livestock fields such as cow sheds, and is configured so that a cylindrical adhesive trap is supported on the entire outer surface of a cylindrical support body assembled from plastic, cardboard, construction paper, etc. (see Patent Document 1), a pest trap that has an attractant specific to pests placed inside a container made from water-resistant paper, etc., and is provided with an attractant means for guiding the attractant to the outside, and has an opening formed inside to allow pests to enter, and pests attach to a replaceable adhesive sheet arranged inside (see Patent Document 2), and a pest trap configured so that a box-shaped structure is formed by assembling plate-shaped materials such as cardboard or plastic film by folding or curving them, and the inside of the bottom wall is coated with an adhesive layer for trapping insects (see Patent Document 3). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2017-6125 [Patent Document 2] Patent Publication No. 2006-25709 [Patent Document 3] Patent Publication No. 2021-114922 Summary of the Invention [Problem to be solved by the invention]

[0006] First, insect traps such as the flying pest capture device disclosed in Patent Document 1 are designed to be installed away from livestock to prevent them from being stepped on, so there is no problem if the sticky trap is exposed on the outer surface of the cylindrical support.However, when applying this to farms where crops are grown, it is necessary to install it around vegetation to avoid contact with the crops, just like conventional insect trapping sheets.

[0007] Insect traps such as the one disclosed in Patent Document 2 have an adhesive sheet inside the container, so they do not come into contact with the adhesive sheet even when placed in the gaps between crops or between leaves, allowing them to capture pests without reducing the commercial value of the crops. However, they require the use of an attractant to attract the pests, which requires the replenishment and replacement of the attractant, and the laborious task of replacing the adhesive sheet, resulting in high production and purchase prices, making the cost of installing multiple traps on a farm prohibitive. Furthermore, the container in this document is an assembly kit consisting of an upper lid, a lower lid, and side walls, and the upper and lower lids are simply inserted into the open top and bottom sections after the side walls are folded into a rectangular cylindrical shape. This makes it easy for moisture to seep in, especially through the gaps between the side walls and the upper lid, when spraying liquid fertilizer or pesticides or watering, potentially causing deterioration of the adhesive sheet and loss of the attractant.

[0008] Insect traps like the one disclosed in Patent Document 1 are designed to be placed on the ground or floor of an agricultural greenhouse, so both sides of the adhesive layer coated inside the bottom wall are always open, and the walls that are folded or curved together are connected and engaged in a male-female relationship, resulting in a structure that is open to the outside and has many gaps. Therefore, as with Patent Document 2, moisture is likely to enter when spraying or watering liquid fertilizer or pesticides, and the adhesive layer is likely to deteriorate. Therefore, this type of insect trap is not suitable for use in the gaps between crops or between leaves, where pests are most likely to gather.

[0009] In view of the above problems, the present invention has been made with the main object of providing an insect trap that is installed on farms where agricultural crops are grown to capture pests, and that is box-shaped and made of inexpensive paper or the like so that it can be easily assembled by the user, the farmer, himself, and that can be installed not only around the planting of agricultural crops but also in places close to the crops where pests are most likely to gather, such as in the gaps between the crops or between the leaves, and that is structured to prevent water from seeping inside when fertilizer or pesticides are sprayed or watered. [Means for solving the problem]

[0010] The present invention is an assembly-type box-type insect trap capable of capturing pests using an adhesive insect trapping sheet disposed inside, and is made by folding each part of a single, water-resistant, yellow- or blue-colored raw sheet into mountain folds or valley folds. After assembly, it has a front wall, a back wall, a left wall, a right wall, and a top wall, but does not have a bottom wall. It is configured to be assembled into a box shape with a lid and no bottom, and is characterized in that one side wall and an upper wall, which are formed by bringing the open ends of the raw sheets together during the assembly process, are configured by overlapping at least a portion of the raw sheets in two or more layers from different directions.

[0011] The specific configuration of the assembled box-type insect trap of the present invention is such that, after assembly, it corresponds to a box-shaped configuration having a front wall, a back wall, a left side wall, a right side wall and an upper wall, and when the original sheet is viewed from the inside, the right outer wall is arranged adjacent to the left of the front wall, the left side wall between the front wall and the back wall, the right inner wall is arranged adjacent to the right of the back wall, the upper outer wall is arranged above the front wall, and the upper inner walls are arranged above the right outer wall and the left side wall, respectively, and by making a valley fold at the boundary between each of these walls, the right side wall is formed by the adjacent right outer wall and right inner wall, and the upper wall is formed by the upper outer wall and each upper inner wall.

[0012] This type of insect trap can be used simply by folding the base sheet with the insect trapping sheet and assembling it into a box shape, making it relatively inexpensive and easy for users to assemble and use themselves. When assembling the base sheet into a box shape, one side wall and the top wall, which are formed by bringing the open ends together, are partially overlapped in two or more layers from different directions. This, combined with the waterproof properties of the base sheet, means that areas prone to gaps after assembly are overlapped in two or more layers from different directions, making it difficult for water to penetrate the interior when spraying fertilizer or pesticides or watering, thereby preventing deterioration of the adhesive surface of the insect trapping sheet for a relatively long period of time and resulting in an insect trap that can be used for a long time. Furthermore, because the adhesive insect trapping sheet is inside the insect trap, it can be placed not only around vegetation in agricultural greenhouses and fields, but also between crops, between leaves, or between tree branches and leaves without damaging the crops, allowing for more efficient capture of pests. This means that the present invention solves the problems of conventional adhesive sheets, which could only be placed around vegetation or which could cause internal water damage if placed too close to crops. The yellow or blue colors of the original sheet are considered to be attractive to pests, and since different colors attract different insects, appropriate colors such as yellow, yellow-green, green, light blue, and blue can be used to match the target pests. By capturing pests attracted to the trap with the internal insect trap sheet, the trap can be used as an insect control measure in agricultural greenhouses and fields, or for pest habitat surveys. When a large number of pests are captured by the insect trap sheet, new traps can be assembled and placed where needed. The original sheet can be made from cardboard, cardboard, resin sheets, fiber sheets, synthetic paper (including resin-based sheets and paper coated or kneaded with resin), etc., which easily maintain their box-like shape after assembly, but cardboard is preferred from a cost perspective. Considering that water is sprayed from above when fertilizer or pesticides are applied or watered, waterproofing can be ensured by making the top wall and side wall (in this case the right wall) double-layered or more.The other side wall (in this case the left wall) is located in a section that continues between the front and back walls of the original sheet, so waterproofing is ensured without the need for a double structure. Note that various configurations of the original sheet that correspond to the unfolded, box-shaped diagram after assembly can be envisioned, and it is easy to reverse the front and back walls of such configurations, or to reverse the left and right side walls, etc.

[0013] In an assembled box-type insect trap of this specific configuration, a slit is formed at the boundary between the right inner wall and the back wall, and an engaging piece is provided adjacent to the right outer wall.The engaging piece is inserted into the slit and assembled to overlap the right outer wall and right inner wall to form the right side wall.This allows the double structure of the right outer wall formed by folding the right side wall from the front and the right inner wall formed by folding the right side wall from the rear and folding it in to be fixed by the insertion relationship of the slit and the engaging piece, thereby improving the waterproof performance of the right side wall.

[0014] In addition, by providing the rear and front portions of the upper protruding piece in the original sheet so that they are continuous with the upper part of the back wall, and folding the rear and front portions of the upper protruding piece at the boundary, an upper protruding piece having a double structure that is longer above the front wall is formed at the top of the assembled back wall, thereby improving the waterproof performance at the upper end of the back wall.

[0015] Furthermore, in this case, the base sheet may have an upper protrusion intermediate portion continuous with the upper portion of the upper outer wall, and an openable locking piece extending from the boundary between the upper outer wall and the intermediate portion of the upper protrusion. During assembly, the upper protrusion intermediate portion is inserted from below between the front and rear portions of the upper protrusion, and the lower end of the front portion is inserted between the locking piece and the upper protrusion intermediate portion to lock it in place. With this configuration, the upper protrusion intermediate portion, which is continuous with the upper outer wall, is inserted between the front and rear portions of the upper protrusion, giving the upper protrusion a triple structure, sealing the gap between the upper outer wall and the upper protrusion, thereby further improving waterproofing performance. Furthermore, because the lower end of the front portion of the upper protrusion is hooked onto the locking piece extending from the boundary between the upper outer wall and the intermediate portion of the upper protrusion, the entire upper protrusion does not expand forward or backward, maintaining waterproofing performance.

[0016] In particular, if a hanging hole that penetrates in the front-to-back direction is formed in the upper protruding piece, the assembled box-type insect trap can be hung between crops by passing a string, cable tie, hook, etc. through this hanging hole.

[0017] Furthermore, in the assembled box-type insect trap of the present invention, it is sufficient to provide an insect trapping sheet inside, but if the insect trapping sheet is attached to the inner surface of either or both of the front wall or back wall, even if the insect trap has a thin box-like shape at the front and back, it is possible to adjust the insect trapping sheet to either or both of the front wall or back wall, which have a relatively large area, and capture as many pests as possible in one placement.

[0018] In this case, by forming a window portion that can be opened outward below the insect trapping sheet on either or both of the front wall or back wall on which the insect trapping sheet is provided, a structure can be realized that makes it easy for pests to enter the inside of the insect trap while preventing the insect trapping sheet from getting wet.

[0019] In particular, since tiny pests have a habit of preferring to enter through small gaps, forming one or more small windows in the window section will help to capture insects more efficiently. [Effects of the Invention]

[0020] The box-type insect trap of the present invention has a simple structure that requires only folding the original sheet and assembling it into a box shape, making it possible to provide an insect trap that users can easily assemble and use themselves at a relatively low cost. To achieve a structure that prevents water from seeping into the trap when applying fertilizer or pesticides or when watering, the original sheet is assembled into a box shape by overlapping portions of the original sheet two or more times from different directions on one side wall and the top wall, which are formed by bringing the open ends together. This not only provides the waterproofing properties of the original sheet, but also provides high waterproofing by overlapping two or more times from different directions in areas where gaps are likely to occur when assembled into a box shape. This prevents water from seeping into the trap when applying fertilizer or pesticides, which are essential for growing crops, or when watering, and can suppress deterioration of the adhesive surface of the internal insect trapping sheet for a relatively long period of time. Furthermore, by providing an adhesive insect trapping sheet inside the insect trap, it can be placed not only around vegetation such as agricultural greenhouses, fields, and trees, as conventional insect trapping tapes are placed, but also in the gaps between crops or between leaves and branches, where pests are more likely to be attracted, without damaging the crops, and it can capture pests more efficiently without reducing the commercial value of the crops.

[0022] Hereinafter, an assembly box-type insect trap 1 as one embodiment of the present invention will be described with reference to the drawings.

[0023] The knockdown box-type insect trap 1 (hereinafter referred to as "insect trap 1") shown in Figures 1 to 4 is made by folding various parts of an original sheet 10 shown in the developed views of Figures 5 and 6 in mountain folds (indicated by two-dot chain lines in Figures 5 and 6) or valley folds (indicated by one-dot chain lines in Figures 5 and 6) to form a thin box-like shape in the front-to-back direction, and then attaching an adhesive insect-trapping sheet 8 to the inside of the assembled original sheet. As shown in Figures 1, 2, 3, and 4, the assembled insect trap 1 has a box-like shape with a lid and no bottom, including a front wall 2, a back wall 3, a left side wall 4, a right side wall 5, and a top wall 6. The upper end of the back wall 3 forms an upward protruding piece 7 that is longer than the front wall 2. The knockdown box-type insect trap 1 can be hung and used by hooking a hanging device such as a string, a cable tie, or a hook into a hanging hole 7h formed in the upper protruding piece 7. In addition, an adhesive insect trapping sheet 8 is attached to the inner surface of the front wall 2 and the back wall 3.

[0024] The raw sheet 10 is made of cardboard with a yellowish color on both sides, which is believed to attract pests. Waterproofing is provided to both sides of the raw sheet by using a yellowish paint or a waterproof paint that is separate from the paint used for coloring.

[0025] The original sheet 10 has a structure in which the components constituting the walls of the insect trap 1 are integrally and continuously arranged. Specifically, as shown in Figures 5 and 6, when viewed from the inside of the original sheet 10, a pair of vertically long rectangular walls, a front wall 2 and a back wall 3, are sandwiched between a narrower left wall 4. A right outer wall 5a, which forms the outer element of the right wall 5, is connected to the left of the front wall 2, and a right inner wall 5b, which forms the inner element of the right wall 5, is connected to the right of the back wall 3. The right outer wall 5a has the same rectangular shape as the left wall 4, while the right inner wall 5b is slightly narrower than the right outer wall 5a and has a trapezoidal shape tapering outward to the right. A slit 5c is formed by cutting in the vertical center of the boundary between the back wall 3 and the right inner wall 5b, while an engagement piece 5d, insertable into the slit 5c, is connected to the vertical center of the left edge of the right outer wall 5a. The engaging piece 5d is roughly trapezoidal and narrower than the right inner wall 5b, but has a wedge-shaped notch at the boundary with the right outer wall 5a to prevent it from slipping out when inserted into the slit 5c.

[0026] In the original sheet 10, an upper outer wall 6a, which serves as the upper element of the upper wall 6, is connected to the upper edge of the front wall 2, and upper inner walls 6b, 6c, which serve as the lower elements of the upper wall 6, are connected to the upper edges of the right inner wall 5b and the left wall 4, respectively. The width of the upper outer wall 6a is equal to the width of the front wall 2, and its height is equal to the widths of the right inner wall 5b and the left wall 4. The widths of the upper inner walls 6b, 6c are equal to the widths of the right inner wall 5b and the left wall 4, and their heights are approximately equal to half the widths of the front wall 2 and the back wall 3.

[0027] In order to form the upward protruding piece 7 along the spine wall 3, the raw sheet 10 has a continuous upper portion of the spine wall 3, the upper portion of the spine wall 3, and the rear portion of the upward protruding piece 7b and the front portion of the upward protruding piece 7a. The rear portion of the upward protruding piece 7b and the front portion of the upward protruding piece 7a are rectangular regions of approximately the same size, and their width is equal to the width of the spine wall 3. Furthermore, the heights of the rear portion of the upward protruding piece 7b and the front portion of the upward protruding piece 7a on the raw sheet 10 are determined so that when the front portion of the upward protruding piece 7a is folded forward at the boundary between the rear portion of the upward protruding piece 7b and the front portion of the upward protruding piece 7a, as viewed from the inside of the raw sheet 10, the lower edge of the front portion of the upward protruding piece 7a (the upper edge before folding) is positioned at approximately the same height as the upper edges of the front wall 2 and the spine wall 3.

[0028] In the base sheet 10, an upper protruding piece intermediate portion 7c, which constitutes part of the upper protruding piece 7, is continuously provided along the upper edge of the upper outer wall 6a. The width of the upper protruding piece 7c is equal to the width of the upper outer wall 6a, and its height is approximately equal to the heights of the upper protruding piece rear portion 7b and the upper protruding piece front portion 7a. Furthermore, in the region of the upper protruding piece intermediate portion 7c, at the center of the width direction at the boundary with the upper outer wall 6a, a substantially rectangular locking piece 7d is formed by cutting out the upper protruding piece intermediate portion 7c while remaining connected to the upper outer wall 6a. This upper protruding piece intermediate portion 7c is assembled by being inserted between the folded upper protruding piece rear portion 7b and the upper protruding piece front portion 7a, and the lower end of the upper protruding piece front portion 7a is inserted and locked onto the back side of the locking piece 7d. Furthermore, the hanging hole portion 7h formed in the upper protruding piece 7 is composed of a single hole that penetrates from front to back, as the round holes 7bh, 7ah, and 7ch formed in the rear portion 7b, front portion 7a, and middle portion 7c of the upper protruding piece, respectively, are connected together after assembly.

[0029] On the inner surface of the raw sheet 10, substantially rectangular insect-trapping sheets 8A, 8B are attached to the area from the upper end to the center of both the front wall 2 and the rear wall 3. The insect-trapping sheets 8A, 8B have their double-sided tape-like backings attached to the inner surface of the front wall 2 and the rear wall 3, and their surfaces are strong adhesive surfaces 8Aa, 8Ba that prevent pests from escaping once they have landed and stuck to them. At the time of sale and before use, release sheets 8Ab, 8Bb are attached to the adhesive surfaces 8Aa, 8Ba, and the release sheets 8Ab, 8Bb are peeled off before use, as shown in Figure 6.

[0030] Rectangular window sections 21, 31 are formed below the insect trapping sheets 8A, 8B on the front wall 2 and rear wall 3. The upper edges of the window sections 21, 31 are connected to the front wall 2 and rear wall 3, respectively, and both side edges and the lower edge are separated from the front wall 2 and rear wall 3. Smaller rectangular windows 21a, 21b, 31a, 31b are cut out and formed in the window sections 21, 31. These window sections 21, 31 can be opened by bending them outward along the upper edges.

[0031] The raw sheet 10 having such a configuration can be assembled into the insect trap 1 as follows. That is, as shown in Figures 5 and 6, when viewed from the inside, the boundaries between the front wall 2 and the right outer wall 5a, the boundary between the front wall 2 and the left side wall 4, the boundary between the left side wall 4 and the back wall 3, and the boundary between the back wall 3 and the right inner wall 5b are each folded in a valley shape (indicated by a dashed line in the figures; the same applies below), the right outer wall 5a is placed on the outside of the right inner wall 5b, and the engagement piece 5d, which has a slight valley fold at the boundary with the right outer wall 5a, is inserted into the slit 5c to form a rectangular tube shape. At this time, the right inner wall 5b is positioned from the rear, and the right outer wall 5a is positioned from the front, forming a double-layered right side wall 5. Next, the upper inner wall 6b is valley-folded at a right angle at the boundary with the right outer wall 5a, and the upper inner wall 6c is valley-folded at a right angle at the boundary with the left wall 4, and the upper outer wall 6a is valley-folded at the boundary with the front wall 2 so as to cover these, thereby forming an upper wall 6 with a double structure, with the upper inner walls 6b and 6c leaning against each other from the left and right, and the upper outer wall 6a leaning against each other from the front.

[0032] Furthermore, the upper protruding piece middle portion 7c is bent at a right angle (indicated by a two-dot chain line in the figure; the same applies below) at the boundary with the upper outer wall 6a to make a mountain fold (shown by a two-dot chain line in the figure) so that it is in close contact with the upper protruding piece rear portion 7b. In this state, the upper protruding piece front portion 7a is folded back at the boundary with the upper protruding piece rear portion 7b to make it in close contact with the upper protruding piece middle portion 7c. At this time, the lower end of the folded upper protruding piece front portion 7a is inserted into the gap between the upper protruding piece 7d, which opens slightly upward and forward, and the upper protruding piece 7c. In this way, the upper protruding piece 7 has a triple structure in which the upper edges of the upper protruding piece rear portion 7b and the upper protruding piece front portion 7a, which are continuous with each other, are folded back and overlapped, and the upper protruding piece middle portion 7c is inserted between them from below. The continuous upper outer wall 6a and upper protruding piece middle portion 7c also seal the gap between the upper wall 6 and the upper protruding piece 7. The insect trap 1 assembled in this manner has the configuration shown in FIG.

[0033] When using the insect trap 1, the upper edges of the windows 21 and 31 are folded in a mountain fold (valley fold when viewed from the outside) toward the front wall 2 and back wall 3, respectively, to open them outward and downward. Furthermore, the release sheets 8Ab and 8Bb of the insect trapping sheet 8 are peeled off to expose the adhesive surfaces 8Aa and 8Ba. This step can be performed either before or after assembling the insect trap 1, but performing it before assembly makes the process of starting use smoother. As described above, the insect trap 1 of this embodiment can be easily assembled from the original sheet 10, so the user can assemble it themselves in a short amount of time and start using it when necessary.

[0034] Since the insect trap 1 assembled in this manner has insect trapping sheets 8A and 8B provided inside, adhesive surfaces 8Aa and 8Ba do not come into direct contact with the leaves or fruits of agricultural crops, and therefore can be placed and used not only around plantings in agricultural greenhouses or fields, but also in narrow spaces such as between crops, between the gaps and leaves of crops, or between the leaves and branches of trees. Furthermore, by hooking a string, cable tie, hook, or the like to the hanging hole 7h of the upward protruding piece 7, the trap can be hung around plantings, between the gaps and leaves of crops, or the like (Fig. 9).

[0035] When insect trap 1 is used near agricultural crops in this manner, even when pesticides, fertilizer, or water is applied, the double-layered structure of upper wall 6 and right side wall 5, which are constructed by joining portions of raw sheet 10 together from different directions when assembled, minimizes gaps and prevents water from entering the interior, thereby preventing water from getting onto adhesive surfaces 8Aa and 8Ba of insect trapping sheet 8. This structure, combined with the inherent waterproofness of raw sheet 10 that constitutes insect trap 1, allows insect trap 1 of this embodiment to be used for a long period of time. After a large number of pests have entered the dark interior of insect trap 1 through the openings on the lower edge of insect trap 1, the gaps on the side and lower edges of window portions 21 and 31, and the smaller openings of small windows 21a, 21b, 31a, and 31b, they are captured on adhesive surfaces 8Aa and 8Ba of insect trapping sheet 8, and the insect trap 1 can be replaced with a new one. This insect trap 1 itself is mainly made up of a paper box with a simple structure, so it can be manufactured and provided to users at a relatively low cost.

[0036] The knockdown box-type insect trap of the present invention is not limited to the configuration of the insect trap 1 described above. The size and shape of the insect trap are not limited to the rectangular box shape of the insect trap 1 described above, but can be variously modified to suit the location of use and the target pests, such as by making the thickness thicker or thinner, increasing or decreasing the length and width dimensions, and by making the trap not only rectangular but also triangular, cylindrical, or elliptical. The window portions 21 and 31 can also be provided on either the front wall 2 or the rear wall 3, and the size, shape, and number of the window portions and small windows can also be modified as appropriate. The color of the insect trap 1 and the base sheet 10 is not limited to the yellow of the above-described embodiment, but can also be selected and changed as appropriate to include yellow, yellow-green, green, light blue, blue, or other yellow- or blue-based colors depending on the type of pest insect to be trapped.

[0037] In the above-described embodiment, one insect trapping sheet 8A, 8B is provided on each of the front wall 2 and the rear wall 3. However, two or more sets of adhesive surface and release sheet may be stacked in layers, and instead of immediately replacing the insect trap 1 after capturing a large number of pest insects on the adhesive surface in use, the adhesive surface with the pests attached and the release sheet underneath may be peeled off to expose the next adhesive surface, allowing continued use until the last (lowest) adhesive surface is used. The insect trapping sheets may be attached to or painted on both or either of the front wall 2 and the rear wall 3. Furthermore, they may be provided not only on the front wall 2 and the rear wall 3, which have relatively large areas, but also on the inner surfaces of the side walls 4, 5 and the top wall 6 of the insect trap 1.

[0038] Various shapes can be realized in the unfolded state before assembly, and the shapes shown in Figures 5 and 6 are just examples. Any other shape in the unfolded state will do as long as it can be assembled into a box-like shape with a lid and no bottom, and the box-type insect trap of the present invention can be constructed by making the top wall and side walls, which are particularly prone to water penetration, at least double-layered.

[0039] Furthermore, the configuration of each part of the assembly box-type insect trap is not limited to the above-described embodiment, and can be modified as appropriate within the scope of the invention. [Industrial Applicability]

[0040] The present invention is extremely useful as an insect trap that can be used efficiently and stably for a long period of time to catch pests that gather around agricultural crops, particularly in agricultural greenhouses, fields, orchards, floriculture gardens, and other farms, and can be provided inexpensively without imposing a large economic burden on users.
