By the way, in order to efficiently capture the flying pests, first, trap the flying pests in the catcher, let the flying pests caught in the catcher enter the catcher, and make it difficult for the flying pests that entered the catcher to escape There is a need. Flying pests such as fly flies have a habit of staying at a high position, and it is desirable that the center of the container is higher than the surroundings.
However, the flying insect capturing device 550 shown in FIG. 12 has a concave area at the center of the lid portion 549, so that flying insects are less likely to stop. For this reason, it has been difficult for the conventional flying pest traps to sufficiently increase the capture efficiency.

  The present invention has been made in view of the above situation, and the purpose of the present invention is to provide a flying insect trap that can improve the trapping efficiency by making flying insects easily stop and invade and escape easily. It is to provide.

The above object of the present invention is achieved by the following configuration.
(1) A capture container comprising a container body having an upper opening, a lid having an attracting opening and attached to cover the upper opening, and containing at least a pest attracting component and housed in the capture container And the attraction opening has a combination structure formed by combining a plurality of cylindrical portions extending in the vertical direction, and the upper surface of the combination structure is centered from the outer periphery of the lid A flying pest trap that has a convex outer shape that becomes higher toward the part, and that attracts and captures pests in the capture container through the attraction opening.

  According to the flying pest trap of the above configuration (1), since the upper surface of the combination structure portion has a convex outer shape that becomes higher from the outer peripheral portion of the lid toward the central portion, the flying pest is in the center. It becomes easy to stay in the part. The attracting opening has a combined structure formed by combining a plurality of cylindrical parts extending in the vertical direction, and has a shape with many intrusions and edges. Easy to enter inside. It takes time for the flying pests that have settled in the center of the attracting opening to reach the outside of the lid. Since there are many intrusions before reaching the outside of the lid, the flying insects are easily guided to the intrusions and are difficult to escape.

(2) The above (1) has at least a part of the cylindrical portion extending downward from the vicinity of the outer peripheral portion of the lid at the center of the bottom surface of the combination structure portion. ) Flying pest trap with the configuration.

  According to the flying pest trap having the configuration (2) above, the flying pest caught in the center of the attracting opening passes through the tunnel-shaped cylindrical entrance and reaches the lowest surface of the lid. . Flying pests that have reached the lowest surface have no direct guide path to the inner wall of the container body, so they are trapped on the lowest surface. Flying pests will jump to nearby drugs while wandering on the bottom.

(3) The flying insect trap of the above configuration (1) or (2), wherein at least a part of the inner surface of the tubular portion is provided with a linear protrusion extending in the vertical direction.

  According to the flying pest trap of the above configuration (3), the linear protrusion extends toward the lowest surface of the lid at the entrance of the cylindrical portion. Since the flying pest that has entered the entrance has a behavioral habit of walking while passing through the linear protrusions, the flying pest can be effectively attracted to the medicine.

  According to the flying insect trap according to the present invention, the flying insect can easily stop and invade, and moreover, it is difficult to escape, thereby improving the capture efficiency.

Embodiments according to the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 and 2, the flying pest trap 11 according to one embodiment of the present invention includes a capture container 13 and a drug 15.
The capture container 13 includes a container body 17 and a lid body 19.
The container body 17 has an upper opening 21. The container main body 17 is formed in a flat rectangular parallelepiped shape, and is placed upright with a pair of maximum area surfaces that are substantially parallel to each other along the vertical direction. In the mounted state, the upper part becomes the upper opening 21 and is opened. The container body 17 is fitted with a lid 19 inside the upper opening 21.

  The lid 19 has an attracting opening 23. The attraction opening 23 has a combination structure portion 27 formed by combining a plurality of cylindrical portions 25 extending in the vertical direction. In the combination structure portion 27, the entrance 29 of the cylindrical portion 25 is formed in, for example, a square (diamond shape). In addition, the entrance 29 may be a polygon such as a triangle, a pentagon, a hexagon, and an octagon, a circle, an oval, or an ellipse. Each tubular portion 25 has an opening edge surrounding the entry port 29 as an edge.

  The attraction opening 23 has a convex outer shape in which the upper surface of the combination structure portion 27 becomes higher as it goes from the outer peripheral portion of the lid body 19 to the central portion. As shown to (a)-(d) of FIG. 5, in this embodiment, the cover body 19 becomes a substantially rectangular shape by planar view. The attracting opening 23 is disposed on the inner side of the outer peripheral frame portion (outer peripheral portion) 31 of the lid body 19. A horizontal upper surface 33 is formed annularly on the outer peripheral frame portion 31 of the lid body 19 along the outer periphery. That is, the attracting opening 23 is disposed so as to be surrounded by the horizontal upper surface 33 of the outer peripheral frame portion 31. The outer peripheral frame 31 is attached to the container body 17 so that the lid 19 covers the upper opening 21 of the container body 17. The flying pest trap 11 assembled by attaching the lid 19 to the container body 17 attracts and captures the pests in the capture container via the attracting opening 23.

  The lid body 19 of the present embodiment is a convex portion formed at the center of the bottom surface of the combination structure portion 27 such that at least a part of the cylindrical portion 25 extends downward from the vicinity of the outer periphery of the lid body 19. 35. As shown in FIG. 3, the convex portion 35 is formed on the inner side (center portion) of the outer peripheral frame portion 31 of the lid body 19. Thereby, the convex part 35 is comprised so that the inner wall surface of the container main body 17 may not be contacted, when the cover body 19 is attached to the container main body 17 (refer FIG. 7). That is, the inner wall surface of the container body 17 and the convex portion 35 are separated from each other. This separation distance is preferably set such that the flying pest does not easily jump from the inner wall surface to the convex portion 35.

  Further, the lid body 19 of the present embodiment is provided with a linear protrusion 37 extending in the vertical direction on the inner surface of a part of the cylindrical portion 25. The linear protrusion 37 is formed in parallel with the axis of the cylindrical portion 25 and continuously from the entry port 29 to the bottom surface of the convex portion 35 with the same height. The linear protrusion 37 has a function of making it easier for the flying pests that have entered the entrance 29 of the attracting opening 23 to travel.

  The flying pest that has entered the intrusion port 29 has a behavioral habit of walking while traveling along the linear protrusion 37 protruding on the inner surface of the cylindrical portion 25. Therefore, the flying pest is attracted to the medicine 15 containing the pest attracting component, and by contacting the medicine 15, for example, by the action of the insecticidal component contained in the medicine 15, or the medicine 15 is liquid or wet. When it is in a shape (jelly, gel, etc.), the wings etc. get wet, and it becomes impossible to act, resulting in death.

  The protruding height of the linear protrusion 37 with respect to the inner surface of the tubular portion 25 is preferably such that the flying pest can get over. Thereby, the flying pest approaching from the inner surfaces on both sides sandwiching the linear protrusion 37 can prevent the linear protrusion 37 from being regarded as a wall surface. In consideration of the behavioral habits of flying pests such as flies and fly 39 (see FIG. 7), the linear protrusions 37 are preferably about 0.5 to 5 mm in height and about 0.5 to 2 mm in width.

  Further, a plurality of linear protrusions 38 may be formed in parallel on the inner wall surface of the container body 17 along the vertical direction. In this case, the flying pest that jumps from the convex portion 35 of the lid body 19 to the inner wall surface of the container body 17 is likely to be guided to the medicine 15 through the linear protrusion portion 38.

Furthermore, the flying insect trap 11 according to the present embodiment has a container shape in which the fly fly 39, which is a flying insect, is easy to stop, easily enter, and escape.
The flying insect trap 11 was shaped like a mountain so that the central part of the lid 19 was higher than the surroundings as “a shape that would easily stop”. The fly fly 39 has a habit of staying at a high position. For this reason, when the center part of the cover body 19 is higher than the circumference | surroundings, it can make it easy to make the fly 39 stop in the center part of the cover body 19 (refer (a) of FIG. 6). After landing, the fly 39 crawls on the lid body 19, but the case where it stops at the center of the lid body 19 is closer to the center of the lid body 19 than the case where it stays near the outside of the lid body 19 as shown in FIG. As shown, since there are many intrusion ports 29 around the fly 39, it is easy to enter the container.
Further, in the flying insect trap 11, the color boundary line between the container body 17 and the lid 19 having different colors is installed on the upper surface, not the container side surface. That is, the boundary line 14 (see FIG. 1) is a boundary between the horizontal upper surface 33 of the outer peripheral frame portion 31 of the lid body 19 and the opening edge of the container body 17 in which the upper opening 21 is formed. The fly fly 39 is considered to have good visibility for a portion having a strong color contrast. The fly fly 39 often stays near the color boundary surface. For this reason, the container color boundary line 14 is configured to be the upper surface so that the lid body 19 having the intrusion port 29 can be held more.

  In the flying insect trap 11, the lid 19 has a shape with a lot of edges and an intrusion opening 29 as an “intrusive shape”, and the intrusion opening 29 is provided on a slope. The shape with many intrusions 29 and edges is realized by a combination structure portion 27 formed by combining a plurality of cylindrical shapes. In other words, in the flying pest trap 11, the intrusion port 29 is provided on the inclined surface, so that the linear distance of the edge becomes longer than in the case where the intrusion port 29 is provided on the horizontal plane, and the intrusion occurs while the fly 39 follows the edge. It becomes easy to enter the mouth 29.

  The flying pest trap 11 has a “shape that is difficult to escape”, and a convex portion 35 provided at the center of the bottom surface of the combination structure portion 27 in the lid 19 is extended to a position closer to the medicine 15, and is formed on the inner wall of the container body 17. The shape does not contact. As a result, the fly 39 that stops at the center of the lid 19 passes through the tunnel-shaped cylindrical portion 25 and reaches the lowest surface of the lid 19, but there is no direct guide path to the inner wall of the container body 17. . For this reason, the fly 39 crawls the lowest surface and jumps to the nearby medicine 15 while wrinkling the lowest surface. Further, the fly 39 that wrinkles the lowest surface of the convex portion 35 wrinkles a position closer to the medicine 15, and thus is easily affected by the volatile insecticidal component and the pest-attracting component contained in the medicine 15. be able to. As a result, the fly 39 is difficult to escape from the flying insect trap 11.

  The medicine 15 contains at least a pest attracting component and is accommodated in the capture container 13, and can be used in various shapes such as liquid, granular, gel, jelly, and solid.

Examples of the carrier for holding the drug 15 include those obtained by pulverizing gel solids prepared with agar, carrageenan, gellan gum, etc. (crush gel, etc.) and those having liquid absorbency such as sponges, sponges, pulp, polymers, etc. Illustrated.
Here, the liquid-absorbing polymer may be either water-absorbing or oil-absorbing. For example, a starch-acrylonitrile graft polymer hydrolyzate, a starch-sodium acrylate graft polymer cross-linked product, and a polyacrylic acid copolymer. Cross-linked product of poly (sodium acrylate), cross-linked product of isobutylene-maleic acid copolymer and its salt, cross-linked product of polyvinyl alcohol acrylate graft polymer, cross-linked poly (vinyl acetate-ethylenically unsaturated carboxylic acid) copolymer Salt, long-chain alkyl acrylate cross-linked polymer, polysorbene, alkylstyrene-divinylbenzene copolymer, methacrylate cross-linked polymer, acrylic acid polymer partial sodium salt cross-linked product, polyacrylic acid copolymer, modified alkylene oxide, etc. Is mentioned.

  And as pest attracting ingredients, for example, Shaoxing liquor, beer, wine, acetoin, black vinegar, red vinegar, vinegar, various fruit extracts, fermented vegetables and fruits, miso, yeast, honey, liquid sugar, brown sugar, sugar, Various vegetable or animal diets can be mentioned.

Furthermore, in order to enhance the control effect of flying pests, for example, pesticide chrysanthemum extract, natural pyrethrin, praretrin, imiprothrin, phthalthrin, allethrin, transfluthrin, resmethrin, phenothrin, ciphenothrin, permethrin, cypermethrin, etofenprox, cyfluthrin, deltamethrin Pyrethroid compounds such as bifenthrin, fenvalerate, fenpropraslin, empensulin, silafluophene, metfurflurin, profluthrin, fenitrothion, diazinon, marathon, pyridafenthion, prothiophos, oxime, chlorpyrifos, dichlorvos, organophosphorus compounds, carbaryl, propoxyl, meso , Carbamate compounds such as thiodicarb, oxadi such as methoxadiazone Sol compounds, phenylpyrazole compounds such as fipronil, sulfonamide compounds such as amidoflumet, neonicotinoid compounds such as dinotefuran and imidacloprid, insect growth control compounds such as metoprene, hydroprene, pyriproxyfen, and orange oil Insecticidal essential oils such as peppermint oil and benzyl alcohol can also be used as insecticidal components.
The content of the insecticidal component is preferably 0.01 to 0.5% by mass in the holding carrier.

  In addition, in order to inhibit the behavior of flying pests (wet the wings and make them immobile), and to capture and die, for example, polybden, natural rubber, guar gum, xanthan, starch, sugars, etc. Thus, high adhesiveness may be imparted to the surface of the medicine 15. Thereby, capture property can further be improved.

Furthermore, in addition to the components described above, other components can be added as appropriate as long as the attractiveness is not hindered.
Examples of the other components include various auxiliary components such as an anti-corrosion inhibitor, a preservative, a pH adjuster, a stabilizer, a pigment, and a fragrance. For example, anti-corrosion agents such as denatonium benzoate (trade name Vitrex) and red pepper extract, quaternary ammonium salts such as cetylpyridinium chloride, preservatives such as potassium sorbate and paraben, citric acid and phosphoric acid salts, etc. PH adjusters, stabilizers such as BHT, BHA, various pigments showing red, blue, yellow, green, black, brown, fragrances such as melon, vanilla, strawberry, mango, apple, pear, banana, durian Perfumes, etc.

Further, examples of the flying pests that are the subject of the present invention include fly species such as Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, and the like.
Furthermore, the present invention is not limited to the above flying pests, but can be applied to flying pests such as mosquitoes and bees.

Next, the operation of the configuration of the flying pest trap 11 according to the above-described embodiment will be described.
In the flying pest trap 11 according to the present embodiment, the upper surface of the combination structure portion 27 has a convex outer shape that becomes higher from the outer peripheral portion of the lid body 19 toward the central portion. ), (B), the fly 39 is likely to stay in the center. The attraction opening 23 has a combined structure portion 27 formed by combining a plurality of cylindrical portions 25 extending in the vertical direction, and has a shape with many intrusions 29 and edges. It is easy to enter the capture container from the entry port 29. The fly 39 that has settled in the center of the attracting opening 23 has a long distance to reach the outside of the lid 19, and must pass through many intrusions 29 before reaching the outside of the lid 19. The fly 39 is easily guided to the entrance 29, and the capture efficiency is improved.

  On the other hand, like the flying insect trap 111 of Comparative Example 1 shown in FIG. 10A, the upper surface of the combination structure 127 formed by combining a plurality of cylindrical portions 125 is the outer peripheral portion of the lid 119. 10, the fly 39 is formed on the top of the wall 141, which is the end of the lid 119, as shown in FIG. 10 (b). Easy to stop. Then, the fly fly 39 caught on the top of the wall 141 may be trapped in the direction opposite to the entrance 129, so that it is not guided to the entrance 129 and travels along the outer surface of the wall 141 to fly a pest. The escaper 111 may escape.

  Further, in the flying pest trap 11 according to the present embodiment, the fly 39 that stops at the center of the attracting opening 23 passes through the entrance 29 of the tubular portion 25 that has a tunnel shape, and is the lowest surface of the lid 19. To reach. The fly 39 that has reached the lowest surface has no direct guide path to the inner wall of the container body 17, so that the lowest surface of the convex portion 35 is trapped. The fly 39 that wrinkles the lowest surface of the convex portion 35 wrinkles a position closer to the medicine 15, and can be easily affected by the volatile insecticidal component and the attracting component contained in the medicine 15. . As a result, the fly 39 is difficult to escape from the flying insect trap 11. Then, the fly 39 reaches the end of the lowest surface of the convex portion 35 while wrinkling, and jumps to the nearby medicine 15.

  On the other hand, when there is no convex portion 35 on the bottom surface of the combination structure portion 27A in the lid 219, like the capture container 213 in the flying pest trap of Comparative Example 2 shown in FIG. 11, the flatness of the combination structure portion 27A is flat. The fly 39 that has reached the bottom surface takes a longer time to wrinkle the bottom surface of the combined structure portion 27A that is wider than the lowest surface of the convex portion 35 (it becomes slower to reach the end of the bottom surface of the combined structure portion 27A). It takes time to jump to.

  Further, in the flying pest trap 11 according to the present embodiment, the linear protrusion 37 extends toward the entry surface 29 of the cylindrical portion 25 toward the lowest surface of the lid body 19. Since the fly 39 that has entered the entrance 29 has a behavioral habit of walking along the linear protrusion 37, the fly 39 can be effectively attracted to the medicine 15.

Next, a modification of the above flying pest trap 11 will be described.
8 and 9 are external perspective views showing modifications of the flying pest trap 11.
The flying pest trap 11 having the above-described configuration has been described with the attracting opening 23 having a convex outer shape that increases from the outer peripheral portion toward the central portion on the lid body 19 that is substantially rectangular in plan view. In addition, the following can be considered as an attracting opening part higher than an outer peripheral part.
That is, as shown in FIG. 8A, the lid 19A having a circular shape in plan view has an attracting opening in which the upper surface of the combined structure portion 27A formed by combining a plurality of cylindrical portions 25A is formed in a hemispherical shape. 43 may be included.
In addition, as shown in FIG. 8 (b), the polygonal lid body 19B in plan view has an attracting opening in which the upper surface of the combination structure portion 27B formed by combining a plurality of cylindrical portions 25B is formed in a pyramid shape. The part 45 may be included.
In addition, as shown in FIG. 8C, the lid body 19C having a circular shape in plan view has an attractive opening in which the upper surface of the combined structure portion 27C formed by combining a plurality of cylindrical portions 25C is formed in a step shape. 47 may be included.
In addition, as shown in FIG. 9A, the lid body 19D having an oblong shape in plan view is an attraction in which the upper surface of the combination structure portion 27D formed by combining a plurality of cylindrical portions 25D is formed in a two-sided shape. An opening 49 may be provided.
In addition, as shown in FIG. 9B, the lid body 19E having a rectangular shape in plan view has an attractive opening in which the upper surface of the combined structure portion 27E formed by combining a plurality of cylindrical portions 25E is formed in a two-stage shape. The part 51 may be included.

  Therefore, according to the flying insect trap 11 according to the present embodiment, the fly fly 39 is easy to stop and invade, and it is difficult to escape, thereby improving the capture efficiency.

Here, the features of the embodiment of the flying pest trap according to the present invention described above will be briefly summarized below.

  Next, the Example performed in order to test the effectiveness of the flying insect trap 11 concerning this invention is demonstrated.

[Test Method 1]
Two kinds of flying insect traps, which are specimens, were installed in a test space of 1.8 m × 1.8 m × 1.8 m.
About 250 heads of Drosophila melanogaster were released as flying pests in the test space.
The number of flying heads to each specimen for 10 minutes after releasing Drosophila melanogaster and the number of heads captured in each specimen after 3 hours were counted. Table 2 and Table 3 below show the results of performing the same test twice and calculating the average value.
Each specimen was prepared by filling 30 g of the medicine 15 in a plastic container body 17 having a length of 6 cm, a width of 2 cm, and a height of 6 cm, and covering the lids 19 and 119 having different shapes. The filling depth of the drug 15 as gel particles was 3.5 cm.
Each of the lids 19 and 119 has a height of 2 cm at the highest portion from the upper part of the container body 17 and has an opening 29 for the cylindrical portion 25 from which the Drosophila melanogaster can enter the container. It was.

[Sample]
As shown in FIG. 1, the sample of Example 1 was a lid 19 having a convex outer shape that becomes higher from the outer periphery toward the center.
The specimen of Comparative Example 1 was a bowl-shaped lid 119 as shown in FIG.

The prescription of the medicine 15 was as shown in Table 1 below.

[Efficacy test results]

  As is clear from Tables 2 and 3 above, a comparative example of the sample of Example 1 having the outer shape with the highest center portion of the lid 19 and the bowl-shaped lid 119 shown in FIG. When compared with one specimen, the number of flying heads was improved by adopting the shape of Example 1. Furthermore, the number of captured heads of Example 1 was about twice that of Comparative Example 1, and the capture efficiency was improved more than the improvement ratio of the number of flying heads. Thereby, it was shown that the shape of Example 1 improves the capture efficiency by making it easy for the flying pests to stop and invade and to escape easily.

[Test Method 2]
Two kinds of flying insect traps, which are specimens, were installed in a test space of 1.8 m × 1.8 m × 1.8 m.
Approximately 200 Drosophila melanogaster were released as flying pests in the test space.
The time from the time when Drosophila flying to each specimen entered the container and reached the bottom of the lid until it jumped to the drug was measured. Table 4 below shows the results of measuring the time from the time when three Drosophila invading each specimen reached the bottom of the lid until they jumped to the drug, and the average value was calculated.
Each specimen was prepared by filling 15 g of the medicine 15 in a plastic container body 17 having a length of 6 cm, a width of 2 cm, and a height of 6 cm, and covering the lids 19 and 219 having different shapes.
Each of the lids 19 and 219 has a height of 2 cm at the highest part from the upper part of the container body 17, and an intrusion port 29 of the cylindrical part 25 is open from which the Drosophila melanogaster can enter the container. It was.

[Sample]
As shown in FIG. 4, the sample of Example 2 was a lid 19 having a convex portion 35 at the center of the bottom surface of the combination structure portion 27.
As shown in FIG. 11, the specimen of Comparative Example 2 was a lid 219 having no convex portion 35 on the bottom surface of the combination structure portion 27A.

[Drug]
The prescription of the medicine 15 was as shown in Table 1 above.

[Efficacy test results]

  As is clear from Table 4 above, the sample of Example 2 having the convex portion 35 on the bottom surface of the combination structure portion 27 is compared with the sample of Comparative Example 2 having no convex portion 35 on the bottom surface of the combination structure portion 27A. Then, the time from reaching the bottom surface of the lid to jumping to the medicine 15 was reduced to about 1/10 by adopting the shape of Example 2. Thereby, it was shown that the shape of Example 2 can be easily attracted to the medicine 15 because the flying pest easily jumps to the medicine 15.
