Description

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

Various flying pest traps with an attractant inside are commercially available for the purpose of controlling flying pests such as 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 to be used.

Conventionally, in order to allow flying pests attracted by an attractant to invade the inside of the trap, there has been a trap provided with a ventilation port having a height difference with respect to the entry port where the flying pests invade (for example, Patent Document 1). reference). The trap of Patent Document 1 has a dome shape whose upper portion is composed of a flat curved surface, and an entrance is provided on the curved surface of the dome portion. As a result, it is said that the pests attracted near the entrance can be attracted to the inside of the container without stopping on the surface of the dome portion and can be captured.

Further, there is also known a trap that provides a perch to flying pests by providing a square-shaped protrusion that protrudes upward of the container (see, for example, Patent Document 2). Patent Document 2 states that an opening for invading flying pests is provided on the side of the protruding portion, and flying pests that have gathered and stopped at the protruding portion can be attracted to the inside of the container from the opening. ..

Japanese Unexamined Patent Publication No. 2002-171889 JP-A-2010-570502

However, in reality, flying pests do not always smoothly invade the inside of the container through the entry port (opening), and may continue to fly in an irregular trajectory. In addition, since flying pests do not always stay near the trap, it is difficult for the attracting component that volatilizes from the entrance to act effectively. Therefore, when capturing a flying pest, it is easier to control the behavior of the flying pest if it is not allowed to fly freely but rather is actively stopped by some object. By doing so, it is considered that the attracting component volatilized from the inside of the container to the outside can surely act on the flying pests and be attracted to the inside of the container.

In this respect, since the trap of Patent Document 1 is formed of a curved surface having a flat outer surface as described above, it is difficult for flying pests to stop on the outer surface of the trap. Therefore, the flying pests that have approached the trap due to the attracting component cannot be captured unless they smoothly invade the inside of the container. Further, since the trap of Patent Document 1 has a simple structure in which an entry port is provided on the dome structure, flying pests easily move in and out of the container with the entry port in between. Therefore, even if the flying pests can be attracted to the inside of the container, if the insecticidal component does not act, the flying pests may escape to the outside.

On the other hand, the trap of Patent Document 2 is provided with a protruding portion for stopping flying pests. This protruding portion is formed by bulging a part of the lid upward to expose it in a square shape. Even if the flying pests stop, the protruding part having such a square shape is easily warned because it is greatly exposed to the surroundings, and there is a risk that the flying pests may escape from the protruding part by feeling the sign of a person or the like. is there. Moreover, in this trap, the protrusion and the openings provided on its sides are not properly arranged and the distance between them is relatively large, so that flying pests move from the protrusion to the opening. It's not easy to move.

As described above, in the current trap, there is a lot of room for improvement in that the flying pests are not wary of flying pests and are surely captured inside the container. The present invention has been made in view of the above problems, and has an excellent attraction effect on flying pests, particularly flying pests typified by fly pests such as Drosophila, flies, Sciaridae, mushroom flies, and butterfly flies. It is an object of the present invention to provide a flying pest trap that exerts a catching effect.

The characteristic configuration of the flying pest trap according to the present invention for solving the above problems is
A flying pest trap that attracts and captures flying pests,
A lid with an attraction port that attracts the flying pests inside,
A tray part that collects flying pests that have invaded the inside from the attraction port,
With
The lid is provided with a carnivorous plant imitation structure for guiding flying pests that have stopped on the outer surface of the lid to the attraction port.

According to the flying pest trap of this configuration, the carnivorous plant imitation structure provided on the lid guides the flying pests that have stopped on the outer surface of the lid to the attraction port, just like a carnivorous plant. Function. Therefore, the flying pests easily invade the inside of the flying pest trap through the attraction port through the carnivorous plant imitation structure. Then, the flying pests that have invaded the inside of the flying pest trap fall into the tray and are captured.

In the flying pest trap according to the present invention
The carnivorous plant mimicry structure is preferably an annular edge portion formed so as to surround the attraction port.

According to the flying pest trap of this configuration, the annular edge portion, which is a carnivorous plant imitation structure, is formed so as to surround the attraction port, so that the flying pests stopped on the outer surface of the lid portion are the annular edge portion. When it reaches a certain position, it becomes easy to invade the inside of the flying pest trap through the attraction port. As a result, the flying pests fall on the tray and are captured.

In the flying pest trap according to the present invention
The carnivorous plant mimicry structure preferably further includes a linear edge portion connected to the annular edge portion.

According to the flying pest trap of this configuration, by further including a linear edge portion connected to the annular edge portion as a carnivorous plant imitation structure, even if the flying pest stops at a position slightly away from the attraction port, the said Flying pests are guided along the linear edge to the annular edge. As a result, the flying pests are more likely to invade the inside of the flying pest trap from the attraction port, fall into the tray, and are caught.

In the flying pest trap according to the present invention
The carnivorous plant mimicry structure is preferably a linear edge portion formed so as to be directly connected to the attraction port.

According to the flying pest trap of this configuration, the linear edge portion, which is a carnivorous plant imitation structure, is formed so as to be directly connected to the attraction port, so that the flying pests stopped on the outer surface of the lid portion can be removed. When it reaches a certain position of the linear edge part, it becomes easy to invade the inside of the flying pest trap through the attraction port. As a result, the flying pests fall on the tray and are captured.

In the flying pest trap according to the present invention
It is preferable that the drug portion containing a scent component derived from a flying pest-attracting plant is housed in the tray portion.

According to the flying pest trap of this configuration, a carnivorous plant imitation structure formed on the lid part by storing the drug part containing the fragrance component (attracting agent) derived from the flying pest attracting plant in the tray part. Combined with this, the imitation of carnivorous plants is further enhanced. As a result, the flying pests are surely attracted to the inside of the flying pest trap, fall to the tray part, and are captured without giving caution to the flying pests.

In the flying pest trap according to the present invention
The flying pest-attracting plant is preferably a plant of the subfamily Taro.

According to the flying pest trap of this configuration, since the attractant contains a scent component derived from a plant of the subfamily Entomophily, which is an entomophily attracting plant, the flying pest is combined with a carnivorous plant mimicry structure. It has a very high attraction effect to, and can provide an excellent flying pest trap.

FIG. 1 is a perspective view of a flying pest trap. FIG. 2 is a perspective view of the tray portion. FIG. 3 is a side view of the flying pest trap. FIG. 4 is a side sectional view of the flying pest trap. FIG. 5 is a plan view of the flying pest trap.

The flying pest trap that catches flying pests represented by flies realizes a state in which the flying pests to be captured are interested (for example, the shape of the container where the flying pests are easy to stop, the volatilization of the attracting component preferred by the flying pests, etc.). By doing so, the flying pests are attracted to the flying pest trap and captured inside. Such a mechanism also exists in the natural world. For example, a carnivorous plant that captures insects and uses them as a nutrient source. A carnivorous plant is a plant in which a part of its leaves and stems has developed as an insect-catching organ, and attracts insects by the shape of the insect-catching organ and the odor emitted from the organ, and catches them for its own nutrition. Carnivorous plant catching methods include pit type, adhesive type, pinch trap type, bag trap type and the like. Among these, for example, Nepenthes and Cephalotus follicle are known as pit-type carnivorous plants. Nepenthes are equipped with a bag-shaped insect-catching organ containing digestive juices, and on the front side of the bag, streaky linear protrusions called wings (often) are formed so as to extend downward from the opening of the bag. Has been done. When an insect stops on a linear process, it has a habit of moving along it. Therefore, when an insect stops on the surface of the Nepenthes bag, it moves along the wings to the opening of the bag, and falls from the opening to the inside of the bag to be captured. In addition, the cephalotus follicle is also equipped with a bag for catching insects, which has streaky linear protrusions called keels similar to Nepenthes, and insects that have stopped on the keel can be dropped into the bag and caught.

On the other hand, although it is not a member of the carnivorous plant, there is a plant (sometimes referred to as "entomophily" or "insect-catching plant") that propagates by attaching pollen to the captured insect. For example, Arisaema serratum is a type of plant belonging to the genus Jack-in-the-Pin of the subfamily Taro, which emits the odor preferred by insects and attracts insects. At this time, since the pollen of Arisaema serratum adheres to the insects, when the insects to which the pollen adheres take off from the Arisaema serratum, they can propagate in a wide range.

Insect capture systems such as carnivorous plants found in the natural world have been devised in various ways for the plants to reproduce, and they function by a rational mechanism. The present inventors have focused on an excellent mechanism for catching insects such as carnivorous plants found in the natural world, wondered if this could be applied to a flying pest trap, and came up with the idea of the present invention. That is, the present invention is a biomimetics-type flying pest trap that imitates a carnivorous plant, and is a completely new type of insect repellent product that has never existed in the past.

Hereinafter, embodiments of the flying pest trap of the present invention will be described with reference to FIGS. 1 to 5. However, the present invention is not intended to be limited to the configurations described in the embodiments and drawings described below.

<Structure of flying pest trap>
FIG. 1 is a perspective view of the flying pest trap 100 of the present invention. The flying pest trap 100 is used to catch and control flying pests such as flies in various environments such as general houses, restaurants, factories, schools and offices. In order to achieve such an object, the flying pest trap 100 includes a tray portion 10 and a lid portion 20. Hereinafter, the tray portion 10 and the lid portion 20 will be described in detail.

[Tray part]
FIG. 2 is a perspective view of the tray portion 10 constituting the lower part of the flying pest trap 100. The tray portion 10 is a cup-shaped container for storing dead flying pests. As shown in FIG. 2, in the tray portion 10, the drug portion 30 is installed at or near the inner bottom portion thereof, and the flying pests are attracted by the attracting component contained in the drug held in the drug section 30, and further by the insecticidal component. It is configured to kill flying pests. The tray portion 10 is provided with an arrangement member 11 for positioning the drug portion 30 substantially in the center. In the present embodiment, the drug portion 30 is arranged substantially in the center of the tray portion 10 by restricting the side surface of the drug portion 30 with the four arrangement members 11. After setting the drug unit 30 between the four arrangement members 11, a fixing part (not shown) is mounted on the arrangement member 11 to fix the drug unit 30. In addition, for fixing the drug portion 30, instead of the arrangement member 11 and the fixing parts, a rod-shaped member penetrating the center of the drug section 30, a clamp for sandwiching the drug section 30, or the like can be adopted.

The tray portion 10 is provided with a flange portion 12 for attaching and detaching the lid portion 20, which will be described later. In the new state, for example, a barrier film (not shown) formed by laminating an aluminum film and a resin film is attached to the flange portion 12 to seal the inside, and the chemical contained in the pharmaceutical portion 30 is dried. Is being prevented. At the time of use, the barrier film is peeled off from the flange portion 12 and fitted with the lid portion 20 with the inside exposed.

A band-shaped protrusion 13 for guiding flying pests to the drug portion 30 is provided on the inner side surface of the tray portion 10. In the present embodiment, the strip-shaped protrusions 13 are provided at four locations on the inner side surface of the tray portion 10 at equal intervals. The size of one strip-shaped protrusion 13 is set to a width of 3 to 10 mm, a thickness of 0.5 to 3 mm, and a length of about 10 to 30 mm. Each band-shaped protrusion 13 is provided over a range from the flange portion 12 to the vicinity of the root of the arrangement member 11. The drug portion 30 is installed so as to be in contact with at least a part of each band-shaped protrusion 13. The flying pests that have invaded the inside of the flying pest trap 100 move toward the lower drug section 30 while traveling along the band-shaped protrusions 13. Then, when the band-shaped protrusion 13 and the drug portion 30 reach the contact position or the vicinity thereof, the flying pest is killed by the action of the insecticidal component contained in the drug. By providing the band-shaped protrusions 13 on the inner side surface of the tray portion 10 in this way, the captured flying pests can be reliably guided to the deep position of the tray portion 10 in which the drug portion 30 is installed, and the drug portion 30 can be reliably guided. The flying pests that have reached and died can be stored in the tray section 10.

As described above, the chemical unit 30 installed in the tray unit 10 volatilizes the attracting component contained in the impregnated chemical to the outside to attract the flying pests to the inside of the flying pest trap 100, and also attracts the flying pests. Flying pests are killed by contacting or ingesting the insecticidal component contained in the drug to the pests. The drug unit 30 can be configured as, for example, an absorbent carrier impregnated with the drug. In this case, for example, pulp non-woven fabric or felt can be used as the carrier. In order to make the carrier thicker, a plurality of thin pulp non-woven fabrics or felts may be laminated. Pulp non-woven fabrics and felts can be web-formed or embossed on the surface by a spunlace method in order to efficiently absorb chemicals while maintaining their shape. Instead of the pulp non-woven fabric or felt, the carrier of the pharmaceutical part 30 may be composed of a sponge, paper, a fiber aggregate or the like capable of absorbing a liquid. Alternatively, a mixture of a liquid attracting component and an insecticidal component and solidified into a gel may be used as the drug portion 30.

The drug includes an attractant for invading the flying pest into the inside of the tray portion 10 and an insecticide for killing the flying pest. In the present invention, as an attractant, one containing a scent component derived from a flying pest attracting plant is used. Examples of flying pest-attracting plants include carnivorous plants such as Nepenthes and Cephalotus, insect-borne flowers of the subfamily Cephalotus, tulips such as tulips, and jasmine and other plants of the genus Sokei. Can be mentioned. Among these flying pest-attracting plants, plants of the genus Jack-in-the-Pest are preferable. In addition, the plants of the genus Tennansho may be classified including the plants of the genus Arum. Therefore, in the present specification, the plants of the genus Tennansho and the plants of the genus Arum are collectively treated as a plant of the genus Tennansho. When a scent component derived from a plant of the genus Jack-in-the-Mole is used as an attractant, the carnivorous plant imitation property of the flying pest trap 100 is further enhanced in combination with the carnivorous plant imitation structure described later. As a result, the flying pests can be reliably attracted and captured inside the flying pest trap without giving caution to the flying pests.

The scent components derived from plants of the genus Jack-in-the-Pine include phenylethyl alcohol, methyl butyrate, α-pinene, ocimene and the like. Of these, phenylethyl alcohol can be suitably used as an attractant for insect repellent products because it exhibits an attracting effect on flying pests if the concentration is less than a certain level, but when the concentration exceeds a certain level, it can be preferably used. May show repellent action against flying pests. Therefore, when phenylethyl alcohol is used as an attractant, the characteristics of the insect repellent product can be controlled by appropriately adjusting the concentration thereof.

The scent component derived from a flying pest attractant plant can also be used in combination with other attractants. Other attractants that can be used together include, for example, 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, and purple potato. Vinegar such as vinegar and sugar cane vinegar, sugar, brown sugar, honey, liquid sugar, glucose, sucrose, malt sugar, tri-warm sugar, oligosaccharide, polysaccharide, citrus sugar, maple syrup, trehalose and other sugars, alcoholic beverages, Examples thereof include vinegar, fruits, processed fruit products, lactic acid products, seafood, processed seafood products, seafood extracts, meat, processed meat products, meat extracts, fragrances and the like. Among these attractants, balsamic vinegar and sanon tou are particularly excellent in attracting flying pests, and therefore, when used in combination with a scent component derived from a flying pest attracting plant, a remarkable attracting effect can be exhibited.

Pesticides include, for example, aresulin, pyrethrin, imiprothrin, phthalthrin, transfluthrin, resmethrin, phenotrin, ciphenotrin, permethrin, cipermethrin, etofemprox, sifluthrin, deltamesrin, bifentrin, fenvalerate, phenpropasrin, empenthrin, Pyrethroid compounds such as silafluofen, metoflutrin, profluthrin, monfluorotrin, natural pyrethrin, insecticide chrysanthemum extract, carbamate compounds such as carbalyl, propoxul, mesomil, thiodicalve, fenitrothione, diazinone, marathon, pyridafenthion, prothiophos, hoxim, chlorpyriphos Organic phosphorus compounds, oxaziazole compounds such as metoxadiazone, phenylpyrazole compounds such as fipronil, sulfonamide compounds such as amide flumeth, neonicotinoid compounds such as dinotefuran and imidacloprid, metoprene, hydroprene, pyriproxyfen. Insect growth control compounds and the like can be mentioned, and these can be used alone or in combination. Among these insecticides, dinotefuran, which is a neonicotinoid compound, is a particularly preferable insecticide because it has low repellent resistance to flying pests and does not inhibit the attracting action of the attractant.

The agent may further contain a moisturizing component such as an aliphatic polyhydric alcohol such as glycerin, a sugar alcohol such as sorbitol, and a thickening polysaccharide such as xanthan gum, in addition to the above-mentioned attractant and pesticide. In this case, the efficacy of the drug can be sustained for a long period of time. The drug is preferably used after adjusting to an appropriate concentration with purified water.

Since the tray portion 10 and the lid portion 20 are detachably configured, the lid portion 20 can be removed to replace the drug portion 30 inside the tray portion 10 or attracted to the inside of the tray portion 10 as necessary. You can take out the dead flying pests that have been killed. The horizontal cross section of the tray portion 10 is formed in a rectangular shape, a circular shape, or the like so that it can be easily installed in a living space such as a kitchen or a living room, but it may be irregular. The bottom area of the tray portion 10 is set to about ^{10 to 100 cm 2} so that the flying pest trap 100 can be installed inconspicuously. Further, if the depth of the tray portion 10 is set to about 1 to 10 cm, the stability is improved while the chemical portion 30 is surely installed. The tray portion 10 is formed in a cup shape by injection molding, vacuum forming, swelling molding, blow molding or the like using a thermoplastic resin.

On the outer surface of the tray portion 10, a recess 14 with which the band-shaped protrusion 13 of another tray portion 10 engages is formed. The recess 14 is provided to improve the loading efficiency of the tray portion 10. When a large number of cup-shaped tray portions 10 are manufactured and stacked in the height direction, the upper end of the strip-shaped protrusions 13 provided on the inner side surface of the tray portion 10 becomes the outer surface of the tray portion 10 stacked on the strip-shaped protrusions 13. Engage with the formed recess 14. Therefore, a plurality of tray portions 10 can be compactly loaded, and the loading efficiency during storage and transportation of the product is improved.

The tray portion 10 is preferably configured to be transparent or translucent. In this case, since the inside of the tray portion 10 in which the flying pests are collected can be reliably visually recognized from the outside, for example, the flying pest trap 100 is easy to handle because it is easy to confirm the attraction effect and grasp the replacement time. be able to. In order to make the tray portion 10 transparent or translucent, for example, a colorless material such as polypropylene resin, PET resin, acrylic resin, polyethylene resin, and polystyrene resin is used as the material of the tray portion 10. Alternatively, the thickness of the tray portion 10 may be formed to be thin so that the inside can be seen through.

[Lid]
FIG. 3 is a side view of the flying pest trap 100 in which the lid portion 20 is attached to the tray portion 10. FIG. 4 is a side sectional view of the flying pest trap 100. FIG. 5 is a plan view of the flying pest trap 100 as seen from the lid 20 side. The lid portion 20 is formed by injection molding, vacuum forming, swelling molding, blow molding or the like using a thermoplastic resin, and is configured as a hollow structure as shown in FIG. The lid portion 20 introduces the outside air into the flying pest trap 100 and diffuses the attracting component contained in the drug portion 30 to the outside. Further, the lid portion 20 prevents the drug portion 30 housed in the tray portion 10 from being exposed. The lid portion 20 includes a connecting portion 21 that engages with the flange portion 12 of the tray portion 10. The connecting portion 21 is configured to accept the flange portion 12 of the tray portion 10 so that it can be connected to the tray portion 10. It is preferable that the connecting portion 21 can be easily attached to and detached from the flange portion 12 by engaging a protrusion or the like, but for example, the connecting portion 21 can be screwed into the flange portion 12. When the connecting portion 21 on the lid portion 20 side and the flange portion 12 on the tray portion 10 side are engaged, the flying pest trap 100 is in use.

As shown in FIGS. 3 to 5, the lid 20 is formed with an attraction port 22 for attracting flying pests to the inside. As shown in FIG. 5, the number and arrangement of the attracting ports 22 are centered on the apex P of the lid portion 20 so that the attracting components contained in the drug portion 30 can be evenly diffused around the flying pest trap 100. It is preferable to provide a plurality of points at the target positions. The shape of the attraction port 22 is not limited to the flower shape shown in FIGS. 3 and 5, and can be configured into any shape such as a round shape, a square shape, and a star shape.

As shown in FIGS. 3 and 5, an annular edge portion 23 formed so as to surround the attraction port 22 is provided on the outer surface of the lid portion 20. Further, a linear edge portion 24 connected to the annular edge portion 23 can be provided on the outer surface of the lid portion 20. The annular edge portion 23 is a protrusion that projects the outer surface of the lid portion 20 outward along the contour of the attraction port 22. The linear edge portion 24 is a protrusion similar to the annular edge portion 23 provided on the outer surface of the lid portion 20. The annular edge portion 23 and the linear edge portion 24 function to guide the flying pests that have stopped on the outer surface of the lid portion 20 to the attraction port 22. That is, when the flying pests stop at the annular edge portion 23 and the linear edge portion 24, the flying pests move along the annular edge portion 23 and the linear edge portion 24 due to the habit. This imitates pit-type carnivorous plants such as Nepenthes and Cephalotus follicularis. With such a carnivorous plant imitation structure, the flying pest trap 100 of the present invention has a ring shape of flying pests stopped on the outer surface of the lid 20 along the linear edge 24, as if it were a carnivorous plant. It can be guided to the edge portion 23, and as a result, the flying pests can easily invade the inside of the flying pest trap 100 from the attraction port 22 beyond the annular edge portion 23. The flying pests that have invaded the attraction port 22 fall into the tray portion 10 and are captured by the flying pest catcher 100.

The protruding height of the annular edge portion 23 and the linear edge portion 24 from the outer surface of the lid portion 20 is preferably 0.1 to 5 mm, more preferably 1 to 3 mm. When the protrusion height of the annular edge portion 23 and the linear edge portion 24 from the outer surface of the lid portion 20 is less than 0.1 mm, the amount of protrusion is insufficient, so that the annular edge portion 23 and the linear edge portion 24 are linear while the flying pests are moving. There is a possibility that it will come off from the edge portion 24 and cannot be guided to the attraction port 22. When the protruding height of the annular edge portion 23 and the linear edge portion 24 from the outer surface of the lid portion 20 exceeds 5 mm, the distance from the upper end portion of the annular edge portion 23 to the inside of the attraction port 22 becomes large, so that the flight flies. Even if the pest approaches the periphery of the attraction port 22, there is a possibility that the pest cannot move to the inside of the flying pest trap 100. The width of the annular edge portion 23 and the linear edge portion 24 is preferably 0.5 to 5 mm, more preferably 1 to 3 mm. If the width of the annular edge portion 23 and the linear edge portion 24 is less than 0.5 mm, the width is insufficient, so that the flying pests are difficult to stop at the annular edge portion 23 and the linear edge portion 24 and cannot be guided to the attraction port 22. There is a risk. If the width of the annular edge portion 23 and the linear edge portion 24 exceeds 5 mm, the flying pests that have stopped at the annular edge portion 23 and the linear edge portion 24 tend to stay on the spot and may not be able to be guided to the attraction port 22. .. The annular edge portion 23 and the linear edge portion 24 may have chamfered corners or rounded corners. In this case, the flying pests that have stopped on the outer surface of the lid can easily cross the step due to the annular edge portion 23 or the linear edge portion 24. It becomes easy to fall into the attraction port 22, and the capture effect thereof can be enhanced.

In FIGS. 3 and 5, the annular edge portion 23 and the linear edge portion 24 are illustrated as carnivorous plant imitation structures, but only the annular edge portion 23 or the linear edge portion 24 constitutes the carnivorous plant imitation structure. It is also possible. For example, if a large number of fan-shaped attraction ports 22 are formed radially around the top P of the lid portion 20 and an annular edge portion 23 is formed so as to surround the radial attraction ports 22, the linear edge portion 24 is not provided. However, flying pests can be attracted to the attraction port 22 only by the annular edge portion 23. Alternatively, if the linear edge portion 24 is formed so as to be directly connected around the attraction port 22 of the lid portion 20, the flying pests can be reached to the attraction port 22 only by the linear edge portion 24 without providing the annular edge portion 23. Can be attracted.

The annular edge portion 23 and the linear edge portion 24 provided on the lid portion 20 are expected to have an excellent effect of attracting flying pests and a catching effect due to the synergistic effect with the attractant contained in the drug portion 30 housed in the tray portion 10. it can. That is, since the attractant contains a fragrance component derived from a flying pest attracting plant, the flying pest trap 100 of the present invention is combined with the carnivorous plant imitation structure of the annular edge portion 23 and the linear edge portion 24. Will be more imitative of carnivorous plants. Therefore, the flying pests can be reliably attracted and captured inside the flying pest trap 100 without giving caution to the flying pests.

As described above, the flying pest catcher 100 of the present invention is a biomimetics type flying pest catcher that imitates a carnivorous plant, and this is a completely new type of epoch-making insect repellent product that has never existed in the past. ..

[Capture test 1: Confirmation of effect by carnivorous plant imitation structure]
Using the flying pest trap having the carnivorous plant mimicry structure of the present invention, a catching test was carried out on Drosophila, which is a typical flying pest. A similar test was also performed on a flying pest trap having no carnivorous plant mimicry structure, and the results were compared with the results of the flying pest catcher of the present invention. The specifications of the flying pest trap used in the capture test 1 are as follows.

<Example 1>
An opaque orange lid portion having a height of 30 mm and a translucent orange tray portion were produced by injection molding of polypropylene resin. Six attraction ports were formed on the lid, and the total opening area of the attraction ports was 1000 mm ² . Further, the lid portion is formed with an annular edge portion that surrounds the attraction port and a linear edge portion that connects to the annular edge portion. In the tray portion, a chemical portion in which a felt (length 50 mm × width 50 mm × thickness 20 mm) was impregnated with a chemical solution was installed. The chemical solution contains balsamic vinegar and sanon tou as an attractant, dinotefuran as an insecticide, glycerin as a moisturizer, and purified water as other components.

<Example 2>
As the lid portion, a lid portion having an annular edge portion surrounding the attraction port but not having a linear edge portion was used. Other configurations were the same as those of the flying pest trap of Example 1.

<Example 3>
As the lid portion, a lid portion having a linear edge portion directly connected to the attraction port but not having an annular edge portion was used. Other configurations were the same as those of the flying pest trap of Example 1.

<Comparative example 1>
As the lid portion, a lid portion having neither an annular edge portion nor a linear edge portion was used. Other configurations were the same as those of the flying pest trap of Example 1.

As a procedure for the capture test 1, first, about ^{300 Drosophila were released into a test room of about 25 m 3} , and the flying pest traps of Examples 1 to 3 or Comparative Example 1 were installed on the floor surface in the center of the test room. After one day, the number of Drosophila captured inside the flying pest trap was counted. This capture test was repeated 3 times to calculate the average number of captured insects. The results of capture test 1 are shown in Table 1.

The flying pest traps of Examples 1 to 3 having an annular edge portion and / or a linear edge portion formed on the lid had an average number of captured insects of about 100 or more. On the other hand, in the flying pest trap of Comparative Example 1 in which neither the annular edge portion nor the linear edge portion was formed on the lid portion, the average number of captured insects remained at about 50. As described above, the flying pest catcher having a carnivorous plant imitation structure is found to have about twice the catching effect as the flying pest catcher having no carnivorous plant mimicking structure, and the flying pest catcher of the present invention is found. Was confirmed to be an excellent insect repellent product.

[Capture test 2: Confirmation of effect by scent components derived from flying pest-attracting plants]
In the flying pest trap having the annular edge portion and the linear edge portion used in Example 1, instead of the chemical solution used in Example 1, a scent component derived from a flying pest attracting plant, dinotefuran, glycerin, and others. A capture test 2 was carried out in the same procedure as the capture test 1 using a drug solution containing a component (purified water, etc.) soaked in the drug part. The results of capture test 2 are shown in Table 2. Regarding the fragrance components derived from the flying insect attracting plants of each example shown in Table 2, phenylethyl alcohol (Example 4), methyl butyrate (Example 5), α-pinene (Example 6), and the like. And ossimen (Example 7) are derived from plants of the genus Jack-in-the-Mole, methyl salicylate (Example 8), and benzaldehyde (Example 9) are derived from plants of the genus Tulip, and jasmine lactone (Example 8). Example 10) and indole (Example 11) are derived from plants of the genus Jasmine.

The flying pest traps of Examples 4 to 11 in which the scent component derived from the flying pest attracting plant was contained in the chemical solution had an average number of trapped insects of about 100 or more, and balsamic vinegar and sanon tou were used as attractants. The catching effect was equal to or better than that of the flying pest catchers of Examples 1 to 3 in which the chemical solution was used. In particular, the flying pest traps of Examples 4 to 7 using the scent component derived from the plant of the genus Jack-in-the-Pine had an average number of trapped insects of about 150 or more, and an extremely remarkable catching effect was observed. It is considered that this is because the plant of the genus Jack-in-the-Pine is a kind of insect-borne flower, and the effect of attracting flying pests is synergistically enhanced in combination with the carnivorous plant-mimicking structure formed on the lid.

The flying pest trap of the present invention can be suitably used for flying pests such as Drosophila, flies, Sciaridae, mushroom flies, and butterfly flies, but the flying pests such as houseflies, black flies, green bottle flies, and flesh flies. It can also be used for flies.
