Description

flying pest trap

[0001] The present invention relates to a flying pest trap that attracts and captures flying pests.

[0002] Various types of flying pest traps equipped with attractants inside are commercially available for the purpose of controlling flying pests such as small flies. In order to efficiently attract flying pests to the flying pest trap, it is necessary to devise the structure of the flying pest trap and the attractant used.

[0003] Conventionally, there has been a trap that has a rectangular protrusion that protrudes upward from the container to provide a perch for flying pests (see, for example, Patent Document 1). The trap in Patent Document 1 has an opening on the side of the protrusion through which flying pests can enter, and is said to be able to attract flying pests that have gathered and landed on the protrusion into the container through the opening.

[0004] The applicant also created a trap in which an attracting opening for attracting flying pests into the lid, which covers the tray containing the medicine, is formed, and an annular edge is formed to surround the attracting opening (see, for example, Patent Document 2). In the trap of Patent Document 2, when a flying pest that has landed on the outer surface of the lid reaches a certain position on the annular edge, it becomes easier for the flying pest to enter the trap through the attracting opening by following the annular edge, and as a result, the flying pest falls into the tray and is captured.

[0005] JP 2010-57502 A JP 2018-102262 A

[0006] The trap in Patent Document 1 is provided with a protrusion for trapping flying pests. This protrusion is formed by bulging a portion of the lid upward to expose a rectangular shape. Even if a flying pest lands on this rectangular protrusion, it is easily alarmed because it is widely exposed to the surroundings, and there is a risk that the flying pest may sense a human presence and escape from the protrusion. Furthermore, in this trap, the protrusion and the opening on its side are not properly positioned, and the distance between them is relatively large, making it difficult for the flying pest to move from the protrusion to the opening.

[0007] The trap in Patent Document 2 has an annular edge formed to surround the lure opening. This annular edge does not bulge out too much and is exposed, so it does not arouse caution, and because it is located close to the lure opening, flying pests can easily move along the annular edge, pass through the lure opening, and into the trap.

[0008] However, it is desirable to guide and capture not only flying pests that land on the trap, but also flying pests that are wandering around the trap, into the trap, but the trap in Patent Document 1 makes flying pests wary of the insects due to its large, exposed protrusions, making it difficult to capture flying pests that are wandering around the trap, and even the trap in Patent Document 2, which improves on this point, still has room for further improvement. The present invention has been made in consideration of the above problems, and aims to provide a flying pest trap that is effective in capturing flying pests that are wandering around the trap.

[0009] Flying pests, such as small flies such as fruit flies, flea flies, sciarid gnats, fungus gnats, and moth flies, have the habit of climbing against gravity (so-called negative geotaxis). We focused on this habit and wondered whether it could be applied to a flying pest trap, which led to the conception of this invention.

[0010] The characteristic configuration of the flying pest trap of the present invention for solving the above problems is a flying pest trap that attracts and captures flying pests, and comprises: a cover portion formed with an attraction opening that attracts the flying pests inside; a tray portion that collects the flying pests that have entered the interior through the attraction opening; and a chemical portion stored in the tray portion, wherein the cover portion has a lid portion and a side portion, and the lid portion has an annular ridge portion that follows the outline of the attraction opening to guide the flying pests to the attraction opening, and further, the side portion extends to the position of the bottom of the tray portion or near there so that the cover portion covers the tray portion.

[0011] With this flying pest trap, when flying pests wandering around the trap reach the side of the cover, which extends to the bottom of the tray or its vicinity, they climb up the side against gravity. Then, when the flying pests reach the annular raised portion on the lid of the cover, they can easily enter the trap through the attraction opening by climbing along it. As a result, the flying pests fall into the tray and are captured. Therefore, the trap can effectively capture flying pests wandering around the trap.

[0012] In the flying pest trap according to the present invention, it is preferable that a linear ridge on the cover surface connected to the annular ridge is provided on the cover.

[0013] In this flying pest trap, the lid has a linear ridge on the lid surface that connects to the annular ridge, so that even if a flying pest lands a little distance from the attraction opening, the flying pest is guided along the linear ridge on the lid surface to the annular ridge. As a result, the flying pest is more likely to enter the trap through the attraction opening and fall into the tray, where it is captured.

[0014] In the flying pest trap according to the present invention, it is preferable that the side portion is provided with a side linear ridge portion extending upward from the bottom surface of the tray portion or its vicinity.

[0015] With this configuration of flying pest trap, a lateral linear ridge is provided on the side portion, extending upward from the bottom of the tray portion or its vicinity, which, combined with the habit of moving along the lateral linear ridge, further enhances negative geotaxis.

[0016] Next, the characteristic configuration of the flying pest trap of the present invention for solving the above problems is a flying pest trap that attracts and captures flying pests, comprising: a cover portion formed with an attraction opening that attracts the flying pests inside; a tray portion that collects the flying pests that have entered the interior through the attraction opening; and a medicinal portion stored in the tray portion, wherein the cover portion has an annular raised portion that follows the contour of the attraction opening to guide the flying pests to the attraction opening, and further, the lower end of the cover portion and the upper end of the tray portion are joined so that no step is created between the cover portion and the tray portion.

[0017] Flying pests wandering around the trap naturally climb the outer surface of the tray section against gravity, passing between the tray section and the cover section and climbing up to the cover section. With this flying pest trap, the lower end of the cover section and the upper end of the tray section are joined so that there is no step between the cover section and the tray section, allowing flying pests to smoothly pass between the tray section and the cover section and climb up to the cover section. When flying pests reach a position where there is a ring-shaped raised section on the cover section, they can easily enter the trap through the attraction opening by climbing down the raised section. As a result, the flying pests fall into the tray section and are captured. Therefore, the trap can effectively capture flying pests wandering around the trap.

[0018] In the flying pest trap according to the present invention, it is preferable that a linear ridge on the cover surface connected to the annular ridge is provided on the cover.

[0019] In this flying pest trap, the cover has a linear ridge on the cover surface that connects to the annular ridge, so that even if a flying pest lands a little distance from the attraction opening, the flying pest is guided along the linear ridge on the cover surface to the annular ridge. As a result, the flying pest is more likely to enter the trap through the attraction opening and fall into the tray, where it is captured.

[0020] In the flying pest trap according to the present invention, it is preferable that the tray portion is provided with a tray surface linear ridge portion extending upward from the bottom surface of the tray portion or its vicinity.

[0021] With this configuration of flying pest trap, a linear raised portion on the tray surface is provided on the tray portion, extending upward from the bottom surface or its vicinity, which, combined with the habit of moving along the linear raised portion on the tray surface, can further enhance negative geotaxis.

[0022] In the flying pest trap according to the present invention, the chemical component preferably contains a sweet flavoring as an attractant component and a neonicotinoid insecticide as an insecticidal component.

[0023] The attractant component of the flying pest trap of this configuration is a sweet flavoring, which improves the quality and tone of the fragrance, making it easier to use in the kitchen, for example. Furthermore, the insecticidal component of the trap is a neonicotinoid insecticide that is low-volatile and therefore has little repellent effect on flying pests, and does not inhibit the attractant effect of the sweet flavoring, resulting in excellent insect capture and killing effects.

[0025] The present invention will be described below with reference to the drawings. However, the present invention is not intended to be limited to the embodiments described below or the configurations shown in the drawings.

[0026] [First embodiment] <Overall configuration> Fig. 1 is an external perspective view of a flying pest trap 1A of the first embodiment. Fig. 2 is an exploded perspective view of the flying pest trap 1A of the first embodiment. The flying pest trap 1A shown in Fig. 1 is used to attract, capture, and control flying pests such as gnats in various environments such as ordinary homes, restaurants, factories, schools, and offices. As shown in Fig. 2, the flying pest trap 1A includes a tray portion 2, a cover portion 3, and a chemical portion 4.

[0027] 2 is formed into a cup shape by injection molding, vacuum molding, expansion molding, blow molding, etc. using a thermoplastic resin. The tray 2 has a tray body 5 and an outward flange 6.

[0028] The tray body 5 is a cup-shaped container that collects flying pests (corpses) that have entered through the attraction ports 21 and 22 described below. The tray body 5 has a chemical container 7 that accommodates the chemical container 4 in a retractable manner, and the chemical container 4 is installed at or near the bottom of the inside of the container, so that the attractant components contained in the chemical container 4 attract flying pests and the insecticidal components kill the flying pests. The horizontal cross section of the tray body 5 is rectangular, circular, or the like to make it easy to install in living spaces such as kitchens and living rooms, but it may also be an irregular shape.

[0029] Positioning members 8 are provided in medication container 7 to position medication portion 4 approximately in the center. In this embodiment, four positioning members 8 restrict the sides of medication portion 4, thereby positioning medication portion 4 approximately in the center of medication container 7. After medication portion 4 is set between the four positioning members 8, medication portion 4 is fixed by attaching a fixing part (not shown) to the positioning member 8. Note that, instead of the positioning members 8 and the fixing part, a rod-shaped member that passes through the center of medication portion 4, a clamp that clamps medication portion 4, or the like can also be used to fix medication portion 4.

[0030] The outward flange 6 is integrally formed on the tray body 5 to allow the cover 3 to be attached and detached. The outward flange 6 is formed to project outward horizontally from the upper edge of the tray body 5 and extend around the entire periphery of the tray body 5. In a new condition, a barrier film (not shown) made of, for example, a laminate of an aluminum film and a resin film is attached to the outward flange 6 to seal the medicine container 7 and prevent the medicine contained in the medicine portion 4 from drying out. When in use, the barrier film is peeled off from the outward flange 6 to expose the interior of the medicine container 7, and the cover 3 is attached to the tray 2.

[0031] The inner side of the tray body 5 is provided with four equally spaced band-shaped protrusions 9 for guiding flying pests to the chemical treatment section 4. In this embodiment, the band-shaped protrusions 9 are provided at four equal intervals on the inner side of the tray body 5. Each band-shaped protrusion 9 is approximately 3-10 mm wide, 0.5-3 mm thick, and 10-30 mm long. Each band-shaped protrusion 9 extends from the outward flange 6 to near the base of the placement member 8. The chemical treatment section 4 is installed so as to contact at least a portion of each band-shaped protrusion 9. Flying pests that enter the flying pest trap 1A move along the band-shaped protrusions 9 downward toward the chemical treatment section 4. The flying pests are then killed by the insecticidal component contained in the chemical treatment. By providing the band-shaped protrusions 9 on the inner side of the tray body 2, captured flying pests can be reliably guided to the chemical treatment section 4.

[0032] <Cover portion> Figure 3 shows the flying pest trap 1A of the first embodiment, with (a) being a plan view and (b) being a side view. As shown in Figures 3(a) and 3(b), the cover portion 3 is formed into an external shape simulating a merry-go-round by injection molding, vacuum molding, expansion molding, blow molding, or the like using a thermoplastic resin. The cover portion 3 has a lid portion 11 that covers the top surface of the tray portion 2 and side portions 12 that cover the side surfaces of the tray portion 2.

[0033] <Lid> The lid 11 is configured as a hollow structure that bulges upward in a hemispherical dome shape so as to cover the entire upper surface side of the tray 2. The lid 11 introduces outside air into the interior of the flying pest trap 1A through attractant openings 21 and 22 (described later), diffusing the attractant component contained in the chemical component 4 (see FIG. 2) to the outside. The lid 11 also prevents the chemical component 4 contained in the chemical component container 7 (see FIG. 2) of the tray 2 from being exposed to the air while ensuring the necessary ventilation performance.

[0034] <Side Portion> The side portion 12 is formed in a tubular (cylindrical) shape that can surround the periphery of the tray portion 2 to cover the entire side surface of the tray portion 2. The side portion 12 is vertically attached integrally to the lid portion 11 so that, when the cover portion 3 is attached to the tray portion 2 in a state that allows it to be used as the flying pest trap 1A, the lower end of the side portion 12 contacts (abuts) or is close to the placement surface S on which the tray portion 2 (flying pest trap 1A) is placed. In this way, the side portion 12 of the cover portion 3 extends to the position of or near the bottom surface of the tray portion 2 so that the cover portion 3 covers the tray portion 2. Note that Figure 3(b) illustrates an example in which the lower end of the side portion 12 is in contact with the mounting surface S, i.e., the side portion 12 extends to the position of the bottom surface of the tray portion 2. However, in the case in which the lower end of the side portion 12 is brought close to the mounting surface S, i.e., the side portion 12 extends to the vicinity of the position of the bottom surface of the tray portion 2, it goes without saying that the gap between the lower end of the side portion 12 and the mounting surface S is set to a size that allows flying pests wandering around on the mounting surface S to move smoothly to the side (outer surface) of the side portion 12.

[0035] The cover 3 has a locking portion 15 near the boundary between the lid 11 and the side surface 12 that can engage with the outward flange 6 of the tray 2. In this example, the locking portion 15 has a claw that elastically engages with the outer periphery of the outward flange 6. This allows the cover 3 to be attached to the tray 2 in an assembled state by placing the cover 3 over the tray 2 and elastically engaging the locking portion 15 of the cover 3 with the outward flange 6 of the tray 2. On the other hand, when a pulling force greater than a certain level is applied between the tray 2 and the cover 3, the elastic engagement of the locking portion 15 is released, allowing the cover 3 to be removed from the tray 2. In this way, the cover 3 can be easily attached to and detached from the tray 2. The method for detachably attaching the cover 3 to the tray 2 is not limited to the above. For example, the engagement portion of the cover 3 can be screwed onto the outward flange 6 of the tray 2.

[0036] <Attraction opening> As shown in Figures 3(a) and (b) , the hemispherical dome-shaped lid portion 11 is provided with a first attraction opening 21 and a second attraction opening 22 for attracting flying pests inside.

[0037] 3(a), the first induction port 21 is formed as a rocking-horse-shaped opening at a position midway between the apex P of the lid portion 11 and the outer periphery at the position where the diameter of the horizontal cross section of the lid portion 11 is greatest. A plurality of first induction ports 21 (four in this example) are arranged around the periphery of the lid portion 11 at a predetermined angular pitch (90° pitch in this example) with the apex P of the lid portion 11 as the center.

[0038] The second induction port 22 is formed as a rounded triangular opening near the outer periphery of the lid portion 11 at the position where the diameter of the horizontal cross section is greatest. A plurality of second induction ports 22 (four in this example) are arranged around the apex P of the lid portion 11 at a predetermined angular pitch (90° pitch in this example) in the circumferential direction of the lid portion 11, and are shifted in phase by a predetermined angle (45° in this example) relative to the first induction port 21 in the circumferential direction of the lid portion 11.

[0039] The shape of the attracting ports 21, 22 is not limited to a rocking horse shape or a triangle shape, but can be any shape, such as a flower shape, a circle shape, a square shape, a star shape, etc. The number and arrangement of the attracting ports 21, 22 are also not particularly limited, and the number and arrangement can be set appropriately so that the attracting component contained in the chemical section 4 is evenly dispersed around the flying pest trap 1A.

[0040] 3( a) and 3(b), the outer surface of the lid portion 11 is provided with a first annular raised portion 31 formed as a protrusion (protrusion) that protrudes (protrudes) outward from the outer surface of the lid portion 11 so as to surround the first attraction port 21. The outer surface of the lid portion 11 is also provided with a second annular raised portion 32 formed as a protrusion (protrusion) that protrudes (protrudes) outward from the outer surface of the lid portion 11 so as to surround the second attraction port 22. The outer surface of the lid portion 11 is also provided with a top annular raised portion 33 formed as a protrusion (protrusion) that protrudes (protrudes) outward in an annular shape around the apex P of the lid portion 11.

[0041] <Linear Ridges> A plurality of linear ridges 41 , 42 , 43 , 44 , and 45 are provided on the outer surface of the cover portion 3 .

[0042] The linear ridges 41, 42 are formed on the lid portion 11 so as to extend radially from the top annular ridge 33 toward the outer periphery of the position (lower end position) where the diameter of the horizontal cross section of the lid portion 11 is greatest.

[0043] The linear ridge portion 41 (hereinafter referred to as the "first lid surface linear ridge portion 41") is formed as a protrusion (protrusion) that protrudes (raise) outward from the outer surface of the lid portion 11 in a form that connects the first annular ridge portion 31 so as to be interposed in the middle.

[0044] The linear ridge portion 42 (hereinafter referred to as the "second lid surface linear ridge portion 42") is formed as a protrusion (protrusion) that protrudes (raise) outward from the outer surface of the lid portion 11 in a form that connects the second annular ridge portion 32 so that it is interposed in the middle.

[0045] The linear ridge 43 (hereinafter referred to as the "third lid surface linear ridge 43") is disposed so as to connect the second annular ridge 32 and the first lid surface linear ridge 41. The third lid surface linear ridge 43 is formed as a protrusion (protrusion) that protrudes (protrudes) outward from the outer surface of the lid portion 11 so as to extend in the circumferential direction of the lid portion 11 in a downwardly convex curved state.

[0046] The linear ridge 44 (hereinafter referred to as the "first side surface linear ridge 44") is provided on the outer surface of the side surface portion 12 so as to extend upward (straight up or diagonally upward) from the position of or near the bottom surface of the tray portion 2. In this example, the first side surface linear ridge 44 is formed as a protrusion (protrusion) that protrudes (protrudes) from the outer surface (outer peripheral surface) of the side surface portion 12 and extends in the vertical direction (up and down direction) toward the lower end of the first lid surface linear ridge 41.

[0047] The linear ridge 45 (hereinafter referred to as the "second side surface linear ridge 45") is provided on the outer surface of the side surface portion 12 so as to extend upward (straight up or diagonally upward) from the position of or near the bottom surface of the tray portion 2. In this example, the second side surface linear ridge 45 is formed as a protrusion (protrusion) that protrudes (raise) from the outer surface of the side surface portion 12 and extends in the vertical direction (up and down direction) so as to be continuous with the lower end of the second cover surface linear ridge 42.

[0048] The protrusion height of the annular ridges 31, 32 and the linear ridges 41-45 from the outer surface of the cover portion 3 is preferably 0.1 to 5 mm, and more preferably 1 to 3 mm. If the protrusion height of the annular ridges 31, 32 and the linear ridges 41-45 from the outer surface of the cover portion 3 is less than 0.1 mm, the amount of protrusion is insufficient, and flying pests may fall off the annular ridges 31, 32 and the linear ridges 41-45 while moving, and may not be guided to the attraction openings 21, 22. If the protrusion height of the annular ridges 31, 32 and the linear ridges 41-45 from the outer surface of the cover portion 3 exceeds 5 mm, the distance from the protruding end of the annular ridges 31, 32 to the inside of the attraction openings 21, 22 becomes too large, and flying pests may not be able to move into the flying pest trap 1A even if they approach the periphery of the attraction openings 21, 22. The width of the annular ridges 31, 32 and the linear ridges 41-45 is preferably 0.5 to 5 mm, and more preferably 1 to 3 mm. If the width of the annular ridges 31, 32 and the linear ridges 41-45 is less than 0.5 mm, the width is insufficient, making it difficult for flying pests to land on the annular ridges 31, 32 and the linear ridges 41-45, and there is a risk that they will not be able to be guided to the attraction openings 21, 22. If the width of the annular ridges 31, 32 and the linear ridges 41-45 exceeds 5 mm, flying pests that land on the annular ridges 31, 32 and the linear ridges 41-45 will tend to remain in place, and there is a risk that they will not be able to be guided to the attraction openings 21, 22. The corners of the annular ridges 31, 32 and the linear ridges 41-45 may be chamfered or rounded. In this case, flying pests that have landed on the outer surface of the lid portion 11 can easily cross the steps created by the annular raised portions 31, 32 or the linear raised portions 41 to 45, and therefore, flying pests that have been lured around the attraction openings 21, 22 can easily fall into the attraction openings 21, 22, thereby increasing the capture effect.

[0049] <Medicine Section> The medicine section 4 installed in the tray section 2 attracts flying pests into the flying pest trap 1A by volatilizing the attractant component contained in the medicine to the outside, and then kills the attracted flying pests by having them come into contact with or ingest the insecticidal component contained in the medicine. The medicine section 4 can be configured, for example, by impregnating an absorbent carrier with the medicine. In this case, for example, pulp nonwoven fabric or felt can be used as the carrier. To increase the thickness of the carrier, multiple thin sheets of pulp nonwoven fabric or felt can be laminated. To efficiently absorb the medicine while maintaining its shape, pulp nonwoven fabric or felt can be spunlaced or embossed to form a web on its surface. Instead of pulp nonwoven fabric or felt, the carrier for the medicine section 4 can be made of a liquid-absorbent sponge, paper, fiber aggregate, or the like. Alternatively, the medicine section 4 can be made of a mixture of liquid attractant and insecticidal components solidified into a gel.

[0050] The chemicals contain an attractant for attracting flying pests into the tray section 2 and an insecticide for killing the flying pests.

[0051] In the present invention, it is preferable to use an attractant containing a sweet flavoring. Examples of sweet flavorings include those containing vanillin-based flavorings. Examples of vanillin-based flavorings include vanillin, ethyl vanillin, acetaldehyde ethyl vanillin acetal, vanillin acetate, ethyl vanillin isobutyrate, acetovanillone, ethyl vanillate, ethyl vanillin propylene glycol acetal, methyl vanillate, vanillic acid, vanillin isobutyrate, butyl vanillate, vanillin 2,3-butanediol acetal, and vanillin lactate, which can be used alone or in combination of two or more. Among these, vanillin and ethyl vanillin are preferred.

[0052] Furthermore, attractants containing fragrant components derived from plants that attract flying pests can also be used. Examples of plants that attract flying pests include carnivorous plants such as the pitcher plant and the pitcher plant, insect-pollinated plants of the Arisaema genus, plants of the Tulipa genus such as tulips, and plants of the Jasminum genus such as jasmine. Among these plants that attract flying pests, Arisaema genus is preferred. Note that Arisaema genus plants are sometimes classified to include Arum genus plants. Therefore, in this specification, Arisaema genus plants and Arum genus plants are collectively referred to as Arisaema genus plants. Using fragrant components derived from Arisaema genus plants as attractants allows flying pests to be reliably attracted to and captured inside the flying pest trap 1A without alarming the flying pests.

[0053] It is also possible to use other attractants in combination. Examples of other attractants that can be used in combination include vinegars such as balsamic vinegar, apple vinegar, rice vinegar, brown rice vinegar, lees vinegar, soybean vinegar, black vinegar, wine vinegar, sudachi vinegar, red vinegar, persimmon vinegar, malt vinegar, purple sweet potato vinegar, and sugarcane vinegar; sugars such as sugar, brown sugar, honey, liquid sugar, glucose, sucrose, maltose, brown sugar, oligosaccharides, polysaccharides, beet sugar, maple syrup, and trehalose; alcoholic beverages, sake lees, fruit, processed fruit products, lactic acid products, seafood, processed seafood products, seafood extracts, meat, processed meat products, meat extracts, and flavorings. Among these attractants, balsamic vinegar and brown sugar are particularly effective in attracting flying pests, and therefore, when used in combination with fragrance components derived from plants that attract flying pests, they can exert a significant attracting effect.

[0054] Examples of insecticides include pyrethroid compounds such as allethrin, prallethrin, imiprothrin, phthalthrin, transfluthrin, resmethrin, fenothrin, cyphenothrin, permethrin, cypermethrin, etofenprox, cyfluthrin, deltamethrin, bifenthrin, fenvalerate, fenpropathrin, empenthrin, silafluofen, metofluthrin, profluthrin, momfluorothrin, natural pyrethrins, and pyrethrum extract; carbaryl, propoxur, methomyl, thiodicarb; Examples of suitable insecticides include organophosphate compounds such as benzophenone, fenitrothion, diazinon, malathion, pyridaphenthion, prothiofos, phoxim, chlorpyrifos, and dichlorvos, oxadiazole compounds such as metoxadiazon, phenylpyrazole compounds such as fipronil, sulfonamide compounds such as amidoflumet, neonicotinoid compounds such as dinotefuran and imidacloprid, and insect growth regulators such as methoprene, hydroprene, and pyriproxyfen, which can be used alone or in combination. Among these insecticides, the neonicotinoid compound dinotefuran is particularly preferred because it has low volatility and therefore little repellency against flying pests, and does not inhibit the attractant action of attractants.

[0055] In addition to the attractant and insecticide, the agent may further contain moisturizing ingredients such as aliphatic polyhydric alcohols such as glycerin, sugar alcohols such as sorbitol, and thickening polysaccharides such as xanthan gum. In this case, the efficacy of the agent can be maintained for a long period of time. The agent is preferably used after adjusting to an appropriate concentration with purified water.

[0056] In the flying pest trap 1A shown in Figure 1 configured as described above, when a flying pest that has landed on the outer surface of the lid portion 11 reaches a position where the annular raised portions 31, 32 are located, it moves along the annular raised portions 31, 32 due to its habit. Furthermore, when a flying pest that has landed on the outer surface of the lid portion 11 reaches the linear raised portions 41, 42, 43, it moves along the linear raised portions 41, 42, 43 due to its habit, is guided to the annular raised portions 31, 32, and when it reaches a position where the annular raised portions 31, 32 are located, it moves along the annular raised portions 31, 32. Flying pests moving along the annular raised portions 31, 32 can easily enter the interior of the flying pest trap 1A through the attraction openings 21, 22 by following the annular raised portions 31, 32. Flying pests that enter the inside of the flying pest trap 1A through the attraction openings 21, 22 fall into the tray section 2 (see Figure 2) and are captured by the flying pest trap 1A.

[0057] On the other hand, when a flying pest wandering around the flying pest trap 1A reaches a position where the first side linear ridge 44 is located, it may, due to its habit, climb up the first side linear ridge 44, cross over to the first lid surface linear ridge 41, and then climb the first lid surface linear ridge 41 and be led directly to the first annular ridge 31, or it may cross from the first lid surface linear ridge 41 to the third lid surface linear ridge 43, move along the third lid surface linear ridge 43 and be led to the second annular ridge 32.

[0058] Furthermore, when a flying pest wandering around the flying pest trap 1A reaches a position where the second side linear ridge 45 is located, it will, due to its habit, climb up the second side linear ridge 45 and be led directly to the second annular ridge 32.

[0059] Furthermore, when a flying pest wandering around flying pest trap 1A reaches the outer surface (outer peripheral surface) of side portion 12 between first side linear ridge 44 and second side linear ridge 45, it will, by its natural tendency, climb up the outer surface of side portion 12 against gravity. When it reaches a position on third lid surface linear ridge 43, it may move along third lid surface linear ridge 43 and be led directly to second annular ridge 32, or it may move from third lid surface linear ridge 43 to first lid surface linear ridge 41, climb up first lid surface linear ridge 41, and be led to first annular ridge 31.

[0060] If flying pests are guided to the first annular raised portion 31, they will move along the first annular raised portion 31 when they reach a position on the first annular raised portion 31. In this case, they will move along the first annular raised portion 31 and easily enter the interior of the flying pest trap 1A through the first attraction opening 21. If flying pests are guided to the second annular raised portion 32, they will move along the second annular raised portion 32 when they reach a position on the second annular raised portion 32. In this case, they will move along the second annular raised portion 32 and easily enter the interior of the flying pest trap 1A through the second attraction opening 22. Flying pests that have entered the interior of the flying pest trap 1A through the attraction openings 21, 22 fall into the tray portion 2 and are captured by the flying pest trap 1A.

[0061] In this way, the flying pests are guided along the linear ridges 41 to 45 to the annular ridges 31, 32. As a result, the flying pests are more likely to enter the inside of the flying pest trap 1A through the attractant openings 21, 22 and fall onto the tray section 2. The flying pests that have fallen onto the tray section 2 and are caught on the upper surface of the chemical section 4 are killed by the insecticidal component contained in the chemical section 4.

[0062] The flying pest trap 1A of the first embodiment can effectively capture flying pests not only that have landed on the cover portion 3, but also those wandering around the cover portion 3. In particular, negative geotaxis can be enhanced, coupled with the tendency of flying pests to move along the side linear ridges 44, 45, further enhancing the trapping effect. Furthermore, the captured and killed flying pests can be easily seen through the attraction ports 21, 22 provided in the cover portion 3 (lid portion 11), allowing the user to experience the insect trapping and killing effect.

[0063] [Second embodiment] Figure 4 is an external perspective view of flying pest trap 1B of the second embodiment. Figure 5 is an exploded perspective view of flying pest trap 1B of the second embodiment. In the second embodiment, parts that are the same as or similar to those in the first embodiment are simply given the same reference numerals in the drawings, and detailed descriptions thereof will be omitted. The following description will focus on parts unique to the second embodiment (the same applies to the third to sixth embodiments described below).

[0064] <Tray section> As shown in Figure 5, the tray section 2 of the flying pest trap 1B of the second embodiment has an inward flange section 55 instead of the outward flange section 6 (see Figure 2) of the tray section 2 of the first embodiment. The inward flange section 55 is formed at a required portion of the circumferential direction of the tray section main body 5 so as to protrude horizontally inward from the upper edge of the tray section main body 5, excluding the portion where the strip-shaped protrusion section 9 is provided, and so as not to interfere with the positioning member 8. Other than that, it is basically the same as the tray section 2 of the first embodiment.

[0065] <Cover section> The cover section 3 is configured as a hollow structure that bulges upward in a hemispherical dome shape so as to cover the entire upper surface side of the tray section 2. That is, in the second embodiment, the cover section 3 is configured mainly with the lid section 11 of the cover section 3 in the first embodiment, and does not have the side section 12.

[0066] In the tray section 2 and the cover section 3, the shape and dimensions of the butting portions of the cover section 3 and the tray section 2 are set so that when the lower end of the cover section 3 and the upper end of the tray section 2 are abutted against each other, the outer peripheral surface of the lower end of the cover section 3 and the outer peripheral surface of the upper end of the tray section 2 are flush with each other.

[0067] The cover unit 3 has a locking portion 56 on its inner periphery that can engage with the inward flange portion 55 of the tray unit 2. In this embodiment, the locking portion 56 has a claw that elastically engages with the outer periphery of the inward flange portion 55. This allows the cover unit 3 to be attached to the tray unit 2 in an assembled state by placing the cover unit 3 over the tray unit 2 and elastically engaging the locking portion 56 of the cover unit 3 with the inward flange portion 55 of the tray unit 2. On the other hand, when a pulling force greater than a certain level is applied between the tray unit 2 and the cover unit 3, the elastic engagement of the locking portion 56 is released, allowing the cover unit 3 to be removed from the tray unit 2. In this way, the cover unit 3 can be easily attached to and detached from the tray unit 2. As in the first embodiment, the engagement portion of the cover unit 3 can also be screwed onto the inward flange portion 55 of the tray unit 2.

[0068] Thus, in the flying pest trap 1B of the second embodiment, the lower end of the cover part 3 and the upper end of the tray part 2 are joined together so that no step is created between the cover part 3 and the tray part 2. The step need only be large enough to make it difficult for flying pests to climb over it, and can be, for example, 0.1 to 3 mm.

[0069] 6 is a plan view of the flying pest trap 1B according to the second embodiment. The hemispherical dome-shaped cover 3 is provided with a first attraction opening 61 and a second attraction opening 62 for attracting flying pests therein.

[0070] The first attraction opening 61 is formed as a flower-shaped opening at a position midway between the apex P of the cover part 3 and the outer periphery at the position where the diameter of the horizontal cross section of the cover part 3 is greatest. A plurality of first attraction openings 61 (three in this example) are arranged around the periphery of the cover part 3 at a predetermined angular pitch (120° pitch in this example) with the apex P of the cover part as the center.

[0071] The second induction openings 62 are formed as leaf-shaped openings near the outer periphery of the cover portion 3 at the position where the diameter of the horizontal cross section is greatest. A plurality of second induction openings 62 (three in this example) are arranged at a predetermined angular pitch (120° pitch in this example) around the apex P of the cover portion 3, and are offset in phase by a predetermined angle (60° in this example) from the first induction openings 61 in the circumferential direction of the cover portion 3.

[0072] The shape of the attracting ports 61, 62 is not limited to a flower shape or a leaf shape, and can be any shape, such as a rocking horse shape, a circle shape, a triangle shape, a square shape, a star shape, etc. The number and arrangement of the attracting ports 61, 62 are also not particularly limited, and the number and arrangement can be set appropriately so that the attracting component contained in the chemical section 4 is evenly dispersed around the flying pest trap 1B.

[0073] <Annular raised portion> A first annular raised portion 71 is provided on the outer surface of the cover portion 3 as a protrusion (protrusion) that protrudes (raise) outward from the outer surface of the cover portion 3 so as to surround the first induction port 61. In addition, a second annular raised portion 72 is provided on the outer surface of the cover portion 3 as a protrusion (raise) that protrudes (raise) outward from the outer surface of the cover portion 3 so as to surround the second induction port 62.

[0074] 4, linear ridges 81, 82, and 83 are provided on the outer surface of the cover portion 3. Furthermore, linear ridges 84 and 85 are provided on the outer surface of the tray portion 2.

[0075] The linear ridge 81 (hereinafter referred to as the "first cover surface linear ridge 81") is formed to extend in a serpentine pattern from the position of the first annular ridge 71 toward the outer periphery of the position (lower end position) where the diameter of the horizontal cross section of the cover part 3 is maximum. The first cover surface linear ridge 81 is formed as a protrusion (protrusion) that protrudes (protrudes) outward from the outer surface of the cover part 3 in a form that connects to the first annular ridge 71.

[0076] The linear ridge 82 (hereinafter referred to as the "second cover surface linear ridge 82") is formed to extend in a serpentine pattern from the position of the second annular ridge 72 toward the outer periphery of the position (lower end position) where the diameter of the horizontal cross section of the cover part 3 is maximum. The second cover surface linear ridge 82 is formed as a protrusion (protrusion) that protrudes (protrudes) outward from the outer surface of the cover part 3 in a form that is connected to the second annular ridge 72.

[0077] The linear ridge portion 83 (hereinafter referred to as the "third cover surface linear ridge portion 83") is formed as a protrusion (protrusion) that protrudes (raises) outward from the outer surface of the cover portion 3 so as to connect the second annular ridge portion 72 and the first cover surface linear ridge portion 81.

[0078] The linear ridge 84 (hereinafter referred to as the "first tray surface linear ridge 84") is provided on the outer surface of the tray part 2 so as to extend upward (straight up or diagonally upward) from the position of or near the bottom surface of the tray part 2. In this example, the first tray surface linear ridge 84 extends upward from the position of the bottom surface of the tray part 2 so as to be continuous with the lower end of the first cover surface linear ridge 81, and is formed as a protrusion (protrusion) that protrudes (raise) from the outer surface (outer peripheral surface) of the tray part 2.

[0079] The linear ridge 85 (hereinafter referred to as the "second tray surface linear ridge 85") is provided on the outer surface of the tray part 2 so as to extend upward (straight up or diagonally upward) from the position of or near the bottom surface of the tray part 2. In this example, the second tray surface linear ridge 85 extends upward from the position of the bottom surface of the tray part 2 so as to be continuous with the lower end of the second cover surface linear ridge 82, and is formed as a protrusion (protrusion) that protrudes (raise) from the outer surface (outer peripheral surface) of the tray part 2.

[0080] In the flying pest trap 1B shown in Figure 4 configured as described above, when a flying pest that has landed on the outer surface of the cover portion 3 reaches a position where the annular raised portions 71, 72 are located, it moves along the annular raised portions 71, 72 due to its habit. Furthermore, when a flying pest that has landed on the outer surface of the cover portion 3 reaches the linear raised portions 81, 82, 83, it moves along the linear raised portions 81, 82, 83 due to its habit, is guided to the annular raised portions 71, 72, and when it reaches a position where the annular raised portions 71, 72 are located, it moves along the annular raised portions 71, 72. Flying pests moving along the annular raised portions 71, 72 are more likely to enter the interior of the flying pest trap 1B through the attraction openings 61, 62 by following the annular raised portions 71, 72. Flying pests that have entered the inside of the flying pest trap 1B through the attraction openings 61, 62 fall onto the tray section 2 and are captured by the flying pest trap 1B.

[0081] On the other hand, when a flying pest wandering around the flying pest trap 1B reaches a position where the first tray surface linear ridge 84 is located, depending on its habit, it may climb up the first tray surface linear ridge 84, cross over to the first cover surface linear ridge 81, and then climb the first cover surface linear ridge 81 and be led directly to the first annular ridge 71, or it may cross over to the third cover surface linear ridge 83 which is provided in a form branching off from the first cover surface linear ridge 81, move along the third cover surface linear ridge 83 and be led to the second annular ridge 72.

[0082] Furthermore, when a flying pest wandering around the flying pest trap 1B reaches a position on the linear raised portion 85 on the second tray surface, it will, due to its habit, climb up the linear raised portion 85 on the second tray surface and be led directly to the second annular raised portion 72.

[0083] Furthermore, when a flying pest wandering around flying pest trap 1B reaches the outer surface (peripheral surface) of tray section 2 between first tray surface linear ridge portion 84 and second tray surface linear ridge portion 85, it naturally climbs against gravity up the outer surface of tray section 2. Then, when it reaches a position at first cover surface linear ridge portion 81 or second cover surface linear ridge portion 82, it moves along first cover surface linear ridge portion 81, second cover surface linear ridge portion 82, or third cover surface linear ridge portion 83, and is led to first annular ridge portion 71 or second annular ridge portion 72.

[0084] If flying pests are guided to the first annular raised portion 71, they will move along the first annular raised portion 71 when they reach a position on the first annular raised portion 71. In this case, they will move along the first annular raised portion 71 and easily enter the interior of flying pest trap 1B through the first attraction opening 61. If flying pests are guided to the second annular raised portion 72, they will move along the second annular raised portion 72 when they reach a position on the second annular raised portion 72. In this case, they will move along the second annular raised portion 72 and easily enter the interior of flying pest trap 1B through the second attraction opening 62. Flying pests that have entered the interior of flying pest trap 1B through the attraction openings 61, 62 fall into the tray portion 2 and are captured by flying pest trap 1B.

[0085] In this way, flying pests are guided along linear ridges 81-85 to annular ridges 71, 72. As a result, the flying pests are more likely to enter the inside of flying pest trap 1B through attractant openings 61, 62 and fall onto tray section 2. The flying pests that fall onto tray section 2 and are caught on the upper surface of chemical section 4 are killed by the insecticidal component contained in chemical section 4.

[0086] Like the flying pest trap 1A of the first embodiment, the flying pest trap 1B of the second embodiment can effectively capture flying pests not only resting on the cover portion 3 but also wandering around the tray portion 2. In particular, this, combined with the tendency of flying pests to move along the linear raised portions 84, 85 on the tray surface, can further enhance negative geotaxis, further improving the capture effect. Furthermore, the captured and killed flying pests can be easily seen through the attraction ports 61, 62 provided in the cover portion 3, allowing the user to experience the insect capture and killing effect.

[0087] [Third embodiment] Figure 7 is an external perspective view of a flying pest trap 1C of a third embodiment. As shown in Figure 7, the flying pest trap 1C of the third embodiment does not have the first side linear ridge portion 44 and the second side linear ridge portion 45 of the flying pest trap 1A of the first embodiment (see Figure 1). In this flying pest trap 1C, when a flying pest wandering around the flying pest trap 1C reaches the outer surface (outer peripheral surface) of the side portion 12, the flying pest will naturally climb up the outer surface of the side portion 12 against gravity. When the flying insect reaches a position where the second annular ridge 32 is located, it is guided directly to the second annular ridge 32, and when it reaches a position where the third lid surface linear ridge 43 is located, it moves along the third lid surface linear ridge 43 and is guided to the second annular ridge 32, or it moves from the third lid surface linear ridge 43 to the first lid surface linear ridge 41, climbs up the first lid surface linear ridge 41, and is guided to the first annular ridge 31. As shown in Figures 7 and 1, linear ridges (41-43; 41-45) connected to the annular ridges 31, 32 are provided on the outer surface of the lid 11 or the outer surfaces of the lid 11 and side surface 12, so that even if the flying insect lands at a position slightly away from the attraction openings 21, 22, the flying insect is guided along the linear ridges (41-43; 41-45) to the annular ridges 31, 32. As a result, the flying pests are more likely to enter the inside of the flying pest traps 1A, 1C through the attraction openings 21, 22, and fall onto the tray section 2 where they are captured.

[0088] [Fourth Embodiment] Figure 8 is an external perspective view of a flying pest trap 1D of the fourth embodiment. As shown in Figure 8, the flying pest trap 1D of the fourth embodiment does not include the first tray surface linear ridges 84 and the second tray surface linear ridges 85 of the flying pest trap 1B of the second embodiment (see Figure 4). When flying pests loitering around this flying pest trap 1D reach the outer surface (peripheral surface) of the tray portion 2, they naturally climb up the outer surface of the tray portion against gravity. Then, when they reach a position corresponding to the first cover surface linear ridges 81, the second cover surface linear ridges 82, or the third cover surface linear ridges 83, they move along the first cover surface linear ridges 81, the second cover surface linear ridges 82, or the third cover surface linear ridges 83 and are guided to the first annular ridges 71 or the second annular ridges 72.

[0089] Fifth Embodiment Figure 9 is an external perspective view of a flying pest trap 1E of a fifth embodiment. As shown in Figure 9, the flying pest trap 1E of the fifth embodiment has attracting openings 61, 62, annular raised portions 71, 72, and linear raised portions 81-83 instead of the attracting openings 21, 22, annular raised portions 31, 32, and linear raised portions 41-43 of the flying pest trap 1C of the third embodiment (see Figure 7). Otherwise, the fifth embodiment is basically the same as the flying pest trap 1C of the third embodiment. The same effects as those of the third embodiment can be achieved with the fifth embodiment.

[0090] Sixth Embodiment Figure 10 is an external perspective view of a flying pest trap 1F of a sixth embodiment. As shown in Figure 10, the flying pest trap 1F of the sixth embodiment differs from the flying pest trap 1E of the fifth embodiment (see Figure 9) in that a linear ridge 86 is formed on the side surface 12 as a protrusion (raised portion) that protrudes (raised) from the outer surface (outer peripheral surface) of the side surface 12. The linear ridge 86 includes a first linear ridge piece 86a, a second linear ridge piece 86b, and a third linear ridge piece 86c. The first linear ridge piece 86a is provided so as to extend in a direction intersecting the vertical direction, in a shape that combines a substantially linear portion and a curved portion, from the lower end position of the side surface 12 to the lower end of the first cover surface linear ridge 81. The second linear ridge piece 86b branches off from the boundary between the substantially straight portion and the curved portion of the first linear ridge piece 86a, and extends in a downward curved manner toward the lower end of the side surface portion 12. The third linear ridge piece 86c branches off from the middle of the substantially straight portion of the first linear ridge piece 86a, and extends in an upward curved manner so as to be continuous with the lower end of the second cover surface linear ridge portion 82. According to the sixth embodiment, it is possible to obtain the same effects as the first and second embodiments, which have the same basic configuration.

[0091] The flying pest trap of the present invention has been described above based on several embodiments, but the present invention is not limited to the configurations described in the above embodiments, and the configuration can be changed as appropriate within the scope of the invention.

[0092] Hereinafter, examples of the flying pest trap of the present invention will be described, but the present invention is not limited to these examples.

[0093] (Capture test: Confirmation of capture effect due to structural differences) Typical flying pests, such as fruit flies, fruit flies, and phorid flies, were used as test insects. Example 1 used the flying pest trap 1E of the fifth embodiment shown in FIG. 9 . Example 2 used the flying pest trap 1F of the sixth embodiment shown in FIG. 10 . Comparative Example 1 used the conventional flying pest trap 200 disclosed in JP 2018-102262 A (see FIG. 11 ). Using the same chemical agent 4, the number of captured insects over a certain period of time was counted, and the relative ratio was calculated. In FIG. 11 , the same parts as those in the above-described embodiments are denoted by the same reference numerals. In the conventional flying pest trap 200 shown in FIG. 11 , the cover portion 3 is formed with a connecting portion 201 that engages with the outward flange portion 6 (see FIG. 2 ) of the tray portion 2. Therefore, in the flying pest trap 200, a step 202 occurs at the engagement portion between the outward flange portion 6 and the connecting portion 201. The results of the trapping test carried out under the above conditions are shown in Table 1 below.

[0094]

[0095] As shown in Table 1, Example 1 achieved a better capture effect than Comparative Example 1. This is thought to be because, in Flying Pest Trap 1E of Example 1, side portion 12 is attached vertically to lid portion 11 in cover portion 3, so no step occurs between lid portion 11 and side portion 12, and test insects can smoothly climb from side portion 12 to lid portion 11, whereas, in Flying Pest Trap 200 of Comparative Example 1, step 202 occurs between cover portion 3 and tray portion 2, and test insects that climb up tray portion 2 stop at the part with step 202 and cannot climb any further.

[0096] In Example 2, when the test insects wandering around the flying pest trap 1F reached the linear ridge 86, they climbed up the linear ridge 86, moved along the linear ridges 81, 82, and 83, and were smoothly guided to the annular ridges 71 and 72. Therefore, as shown in Table 1, in Example 2, compared to Example 1, the negative geotaxis was enhanced, which increased the likelihood that the test insects would enter the trap through the attraction openings 61 and 62, and it is believed that an even better capture effect was achieved for the test insects as a whole.

[0097] Although the data is not presented, when a test similar to the above capture test 1 was conducted using the flying pest trap 1A of the first embodiment shown in Figure 1 and the flying pest trap 1C of the third embodiment shown in Figure 7, it was confirmed that the flying pest trap 1A shown in Figure 1 had a higher capture effect due to the effect of increasing negative geotaxis by the linear ridges 44, 45.

[0098] The flying pest trap of the present invention is particularly suitable for use against small flies such as fruit flies, flea flies, black fungus gnats, mushroom gnats, and house flies, but can also be used against flies such as house flies, blow flies, blow flies, and flesh flies.
