Description

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

  For the purpose of controlling flying pests such as fly flies, various flying pest traps with an attractant inside are commercially available. In order to attract flying pests efficiently to the flying pest catcher, it is necessary to devise the structure of the flying pest catcher and the attractant used.

  Conventionally, there has been a trap provided with a ventilation opening having a height difference with respect to an entrance through which the flying pest invades in order to cause the flying pest attracted by the attractant to enter the inside of the trap (for example, Patent Document 1). reference). The trap of Patent Document 1 has a dome shape with a flat curved surface at the top, and an entrance is provided on the curved surface of the dome. Thereby, it is supposed that the pest attracted to the vicinity of the entrance can be attracted and captured inside the container without stopping on the surface of the dome.

  In addition, a trap is also known that has a square-shaped protruding portion that protrudes upward from the container, and gives a perch to flying insects (see, for example, Patent Document 2). Patent Document 2 is provided with an opening through which the flying pest invades on the side of the protruding portion, and the flying pest that has gathered and stopped at the protruding portion can be attracted from the opening to the inside of the container. .

JP 2002-171889 A JP 2010-570502 A

  However, actually, the flying pest does not always smoothly enter the container from the entrance (opening) and may continue to fly in an irregular locus. In addition, since flying insect pests do not always stay near the trap, it is difficult to effectively act the attracting component that evaporates from the entrance. Therefore, when capturing a flying pest, it is easier to control the behavior of the flying pest rather than letting it fly freely rather than stopping it on some object. By doing so, it is considered that the attracting component that volatilizes from the inside of the container to the outside can act on the flying pests and can be attracted to the inside of the container.

  In this respect, the trap of Patent Document 1 is configured with a curved surface with a flat outer surface as described above, so that flying insects are unlikely to stop on the outer surface of the trap. Therefore, unless the flying pest approaching the trap by the attracting component enters the container smoothly as it is, it cannot be captured. Moreover, since the trap of patent document 1 is a simple structure which provided only the entrance on the dome structure, the flying insects are easy to go inside and outside the container across the entrance. Therefore, even if the folding insect or flying pest can be attracted to the inside of the container, the flying insect may escape to the outside if the insecticidal component does not act.

  On the other hand, the catcher of Patent Document 2 is provided with a protrusion for stopping flying insect pests. This protruding portion is a portion of the lid bulged upward and exposed in a square shape. Even if the flying pest stops, the protruding part having such a square shape is exposed to the surroundings so that it is easy to be wary, and there is a possibility that the flying pest may escape from the protruding part due to the feeling of a person. is there. In addition, in this trap, the protrusion and the opening provided on the side thereof are not properly arranged, and the distance between the two is relatively large. It is not easy to move.

  Thus, in the current traps, there is much room for improvement in that the flying pests are not wary and are reliably captured inside the container. The present invention has been made in view of the above problems, and has an excellent attracting effect on flying pests, particularly flying pests typified by fruit flies such as Drosophila, flea flies, fly flies, mushroom flies, and fly flies. It is another object of the present invention to provide a flying pest trap that exhibits a trapping effect.

The characteristic configuration of the flying pest trap according to the present invention for solving the above problems is as follows.
A flying pest trap that attracts and captures flying pests,
A lid portion formed with an attraction opening for attracting the flying pests inside;
A tray portion for storing flying pests that have entered the interior from the attraction opening;
With
The lid portion is provided with a carnivorous plant mimicking structure for guiding the flying pests that have stopped on the outer surface of the lid portion to the attracting port.

  According to the flying insect trap of this configuration, the carnivorous plant mimicking structure provided in the lid part guides the flying insects that have stopped on the outer surface of the lid part to the attracting mouth as if they were carnivorous plants. Function. Therefore, the flying pests can easily enter the flying pest trap through the attractant opening through the carnivorous plant mimicking structure. Then, the flying pest that has entered the inside of the flying pest catcher falls on the tray and is captured.

In the flying insect trap according to the present invention,
It is preferable that the carnivorous plant mimicking structure is an annular edge portion formed so as to surround the attraction opening.

  According to the flying insect trap of this configuration, since the annular edge portion that is a carnivorous plant mimicking structure is formed so as to surround the attracting mouth, the flying insect that stops on the outer surface of the lid portion is the annular edge portion. When it reaches a certain position, it becomes easier to enter the flying insect trap through the attracting port. As a result, the flying pest falls on the tray and is captured.

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

  According to the flying pest trap of this configuration, even if the flying pest stops at a position slightly away from the attracting port by further including a linear edge portion connected to the annular edge portion as a carnivorous plant mimicking structure, The flying pest is guided to the annular edge portion along the linear edge portion. As a result, the flying insects are more likely to enter the flying insect trap from the attracting port, and fall into the tray portion and are captured.

In the flying insect trap according to the present invention,
The carnivorous plant mimicking structure is preferably a linear edge portion formed so as to be directly connected to the attraction opening.

  According to the flying insect trap of this configuration, the linear edge portion which is a carnivorous plant mimicking structure is formed so as to be directly connected to the attracting opening, so the flying insect that has stopped on the outer surface of the lid portion is When it reaches a position where the linear edge portion is located, it easily travels into the inside of the flying insect trap through the attracting port. As a result, the flying pest falls on the tray and is captured.

In the flying insect trap according to the present invention,
It is preferable that a drug part containing a scent component derived from a flying insect attractant plant is stored in the tray part.

  According to the flying insect trap of this configuration, the carnivorous plant mimicking structure formed on the lid part by storing the drug part containing the scent component (attractant) derived from the flying insect attractant plant in the tray part In combination with this, the mimicry of carnivorous plants is further enhanced. As a result, the flying pest is surely attracted to the inside of the flying pest trap without falling alert to the flying pest, and is dropped and captured on the tray portion.

In the flying insect trap according to the present invention,
The flying pest attracting plant is preferably a plant belonging to the taro family.

  According to the flying pest trap of this configuration, the attracting agent contains the scent component derived from the plant of the subfamily Araceae of the insect pest that is a flying pest attractant plant. The attracting effect on the water is extremely high, and an excellent flying pest trap can be provided.

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 insect trap. FIG. 5 is a plan view of the flying pest trap.

  A flying insect trap that captures flying insect pests represented by fly flies achieves the state in which the flying insect to be captured is interested (for example, the shape of a container that can easily stop flying insects, volatilization of the attracting components preferred by flying insects, etc.) By doing so, the flying pest is attracted to the flying pest trap and captured inside. Such a mechanism also exists in nature. For example, an insectivorous plant that captures insects and uses it as a nutrient source is an example. A carnivorous plant is a plant in which a part of leaves and stems has developed as a trapping organ. The insect attracts the insect by the shape of the trapping organ, the smell emitted from the trapping organ, etc., and traps it to serve as its own nutrition. Insect-carrying methods for carnivorous plants include pitfalls, adhesives, pinch-types, and bag-types. Among these, for example, Nepenthes and Oysters are known as pitfall carnivorous plants. The Nepenthes are equipped with a pouch-shaped insect trapping organ that contains digestive juice, and the front side of the pouch is formed with a line-like protrusion called a wing (well) that extends downward from the opening of the pouch. Has been. Insects have a habit of moving along a linear process when they stop. Therefore, when an insect stops on the surface of the cradle bag, it moves along the wing to the opening of the bag, and falls into the bag from the opening and is captured. In addition, the owl is also equipped with an insect trapping bag having a line-like linear projection called a keel similar to the moray pod, and insects that have stopped on the keel can be dropped into the bag and captured.

  On the other hand, there are plants that do not belong to carnivorous plants, but propagate by attaching pollen to captured insects (sometimes referred to as “insect flower” or “catch insect plant”). For example, mamushigusa is a member of the genus Tennansho of the taro family, and it attracts insects by releasing the scent preferred by insects. At this time, the pollen of the maple grass adheres to the insects. Therefore, when the insect with the pollen flies off from the maple grass, it can propagate widely.

  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 in a rational manner. The present inventors have focused on the excellent insect trapping mechanism such as carnivorous plants found in the natural world, thought that this could be applied to a flying insect trap, and came up with the present invention. That is, the present invention is a biomimetic type flying insect trap that mimics a carnivorous plant, and is a completely new type of insect repellent product that has never existed before.

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

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

[Tray part]
FIG. 2 is a perspective view of the tray unit 10 constituting the lower part of the flying pest trap 100. The tray unit 10 is a cup-shaped container that stores dead insects. As shown in FIG. 2, the tray unit 10 is provided with a drug unit 30 at or near the inner bottom thereof, attracts flying pests by an attracting component contained in the drug held in the drug unit 30, and further by an insecticidal component. It is configured to kill flying pests. The tray part 10 is provided with an arrangement member 11 for positioning the drug part 30 at substantially the center. In the present embodiment, by restricting the side surface of the drug part 30 with the four arrangement members 11, the drug part 30 is arranged at substantially the center of the tray part 10. After setting the drug part 30 between the four arrangement members 11, a fixing part (not shown) is mounted on the arrangement member 11, and the drug part 30 is fixed. In addition, for fixing the drug part 30, it is possible to employ a rod-like member that penetrates the center of the drug part 30, a clamp that holds the drug part 30, or the like instead of the arrangement member 11 and the fixing parts.

  The tray portion 10 is provided with a flange portion 12 for attaching and detaching a lid portion 20 described later. In the new state, for example, a barrier film (not shown) formed by laminating an aluminum film and a resin film is adhered to the flange portion 12 to seal the inside, and the medicine contained in the medicine portion 30 is dried. Is preventing. 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.

  On the inner side surface of the tray part 10, a band-like protrusion 13 for guiding the flying pests to the drug part 30 is provided. In the present embodiment, four strip-shaped protrusions 13 are provided at equal intervals on the inner side surface of the tray unit 10. The size of one band-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 of the band-shaped protrusions 13 is provided over a range from the flange 12 to the vicinity of the root of the arrangement member 11. The drug part 30 is installed so as to be in contact with at least a part of each belt-like projection part 13. The flying pest that has entered the inside of the flying pest trap 100 moves toward the drug part 30 below while traveling along the belt-like protrusion 13. And if it reaches | attains to the position where the strip | belt-shaped projection part 13 and the chemical | medical agent part 30 contact, or its vicinity, a flying insect will be killed by the effect | action of the insecticidal component contained in a chemical | medical agent. Thus, by providing the belt-like protrusion 13 on the inner side surface of the tray unit 10, the captured flying pest is reliably guided to a deep position of the tray unit 10 where the drug unit 30 is installed, and the drug unit 30. The flying pests that have reached and died can be stored in the tray section 10.

  As described above, the drug unit 30 installed in the tray unit 10 volatilizes the attracting component contained in the soaked drug to the outside, attracts the flying pests to the inside of the flying pest trap 100, and attracted flying. Flying pests are killed by contacting or ingesting insecticides contained in the drug against the pests. The drug part 30 can be configured, for example, as a drug soaked in an absorbent carrier. In this case, for example, a pulp nonwoven fabric or felt can be used as the carrier. In order to make the carrier thick, a plurality of thin pulp nonwoven fabrics or felts may be laminated. In order to efficiently absorb the drug while maintaining the shape of the pulp nonwoven fabric or felt, a web can be formed on the surface or embossed by the spunlace method. Instead of pulp nonwoven fabric or felt, the carrier of the drug part 30 may be composed of sponge, paper, fiber aggregate, etc. that can absorb liquid. Alternatively, a liquid attracting component and an insecticidal component mixed into a gel may be used as the drug part 30.

  The medicine includes an attractant for causing the flying pests to enter the inside of the tray unit 10 and an insecticide for killing the flying pests. In the present invention, an attractant containing a scent component derived from a flying pest attractant plant is used. Flying insect pest attracting plants include carnivorous plants of the genus Nematode genus and the genus Fukuroyukinosita, a genus of the genus Tennan that is included in the subfamily of aratomaceae, the tulip genus plant such as tulip, and the moss genus plant such as jasmine. Can be mentioned. Of these flying insect pest attracting plants, Tennansho spp. Plants are preferred. In addition, a tennansho genus plant may be classified including an alum genus plant. Therefore, in this specification, the Tennansho genus plant and the Alum genus plant are combined and handled as a Tennansho genus plant. When a scent component derived from a Tennansho plant is used as an attractant, the carnivorous plant mimicry of the flying insect trap 100 is further enhanced in combination with the carnivorous plant mimicking structure described later. As a result, it is possible to reliably attract and capture the flying pests inside the flying pest trap without giving warning to the flying pests.

  In addition, as a fragrance | flavor component originating in the plant of a Tennansho genus plant, they are phenylethyl alcohol, methyl butyrate, (alpha) -pinene, ocimen, etc. Of these, phenylethyl alcohol exhibits an attracting action against flying pests if the concentration is below a certain level, so it can be suitably used as an attractant for insect repellent products, but when the concentration is above a certain level May have repellent action against flying pests. Therefore, when phenylethyl alcohol is used as an attractant, it is possible to control the characteristics of the insect-proof product by appropriately adjusting the concentration.

  The scent component derived from the flying insect attractant plant can be used in combination with other attractants. Other attractants that can be used in combination include, for example, balsamic vinegar, apple vinegar, rice vinegar, brown rice vinegar, straw vinegar, soybean vinegar, black vinegar, wine vinegar, sudachi vinegar, red vinegar, straw vinegar, malt vinegar, purple potato Vinegar, sugarcane vinegar and other vinegars, sugar, brown sugar, honey, liquid sugar, glucose, sucrose, maltose, trisaccharide, oligosaccharides, polysaccharides, sugar beet sugar, maple syrup, trehalose and other sugars, alcoholic beverages, Examples include sake lees, fruits, fruit processed products, lactic acid products, seafood, processed seafood products, seafood extracts, meat, processed meat products, meat extracts, and fragrances. Among these attractants, balsamic vinegar and tri-sugar are particularly excellent in attracting effects against flying pests, and therefore, when used in combination with scent components derived from flying insect attracting plants, a remarkable attracting effect can be exhibited.

  Examples of the insecticide include allethrin, praretrin, imiprothrin, phthalthrin, transfluthrin, resmethrin, phenothrin, ciphenothrin, permethrin, cypermethrin, etofenprox, cyfluthrin, deltamethrin, bifenthrin, fenvalerate, empensulin, Pyrethroid compounds such as silafluophene, metfluthrin, profluthrin, monfluorothrin, natural pyrethrin, pesticide chrysanthemum extract, carbamate compounds such as carbaryl, propoxl, mesomil, thiodicarb, fenitrothion, diazinon, marathon, pyridafenthion, prothiophos, phoxime, chlorpyrifos dichlor Organic phosphorus compounds, oxadiazoles such as methoxadiazone Compounds, phenylpyrazole compounds such as fipronil, sulfonamide compounds such as amidoflumet, neonicotinoid compounds such as dinotefuran and imidacloprid, insect growth control compounds such as metoprene, hydroprene, pyriproxyfen, etc. They can be used alone or in combination. Among these insecticides, dinotefuran, a neonicotinoid compound, is a particularly preferred insecticide because it has low repellency against flying insects and does not inhibit the attracting action of the attracting agent.

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

Since the tray unit 10 and the lid unit 20 are configured to be detachable, the lid unit 20 is removed as necessary to replace the drug unit 30 inside the tray unit 10 or to attract the inside of the tray unit 10. The dead carcasses of flying pests that have been killed can be taken out. The horizontal section of the tray unit 10 is configured 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 may be indefinite. The bottom area of the tray unit 10 is set to about 10 to 100 cm ² so that the flying pest trap 100 can be installed without conspicuous. Moreover, if the depth of the tray part 10 is set to about 1-10 cm, stability will become favorable, installing the chemical | medical agent part 30 reliably. The tray unit 10 is formed into a cup shape by injection molding, vacuum molding, bulging molding, blow molding, or the like using a thermoplastic resin.

  On the outer surface of the tray portion 10, a recess 14 is formed to engage with a belt-like protrusion 13 of another tray portion 10. The recess 14 is provided in order to improve the loading efficiency of the tray unit 10. When a large number of cup-shaped tray portions 10 are manufactured and stacked in the height direction, the upper ends of the strip-shaped protrusions 13 provided on the inner surface of the tray portion 10 are placed on the outer surface of the tray portion 10 stacked thereon. Engages with the formed recess 14. For this reason, it becomes possible to stack a plurality of tray sections 10 in a compact manner, and the loading efficiency during storage and transportation of products is improved.

  The tray unit 10 is preferably configured to be transparent or translucent. In this case, since the inside of the tray part 10 in which the flying pests accumulate can be surely seen from the outside, for example, the flying pest trap 100 can be easily handled by confirming the attracting effect and grasping the replacement time. be able to. In order to configure the tray unit 10 to be transparent or translucent, for example, a colorless material such as polypropylene resin, PET resin, acrylic resin, polyethylene resin, polystyrene resin or the like is used as the material of the tray unit 10. Alternatively, the tray portion 10 may be formed with a small thickness so that the inside can be seen through.

[Cover]
FIG. 3 is a side view of the flying insect 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 20 is formed by injection molding using a thermoplastic resin, vacuum molding, bulging molding, blow molding, or the like, and is configured as a hollow structure as shown in FIG. The lid part 20 introduces outside air into the flying pest trap 100 and diffuses the attracting component contained in the drug part 30 to the outside. Moreover, the cover part 20 prevents the medicine part 30 accommodated in the tray part 10 from being exposed. The lid portion 20 includes a connection 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 the connecting portion 21 can be connected to the tray portion 10. Although it is preferable that the connecting portion 21 can be easily attached to and detached from the flange portion 12 by engagement of protrusions or the like, 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 portion 20 is formed with an attracting port 22 for attracting flying insects 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 diffused uniformly around the flying insect trap 100. It is preferable to provide a plurality of points at positions to be pointed. The shape of the attracting hole 22 is not limited to the flower shape shown in FIGS. 3 and 5, and can be configured in 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 is provided on the outer surface of the lid portion 20 so as to surround the induction port 22. Furthermore, 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 projection in which the outer surface of the lid portion 20 protrudes outward along the outline of the induction port 22. The linear edge portion 24 is a projection 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 attracting port 22. That is, when the flying pest stops at the annular edge portion 23 and the linear edge portion 24, the flying pest moves along the annular edge portion 23 and the linear edge portion 24 due to the habit. This is an imitation of pitfall-type carnivorous plants such as Nepenthes and Oysters. With such a carnivorous plant mimicking structure, the flying insect trap 100 of the present invention loops the flying insects that have stopped on the outer surface of the lid 20 along the linear edge portion 24 as if they were carnivorous plants. As a result, the flying insects can easily enter the inside of the flying insect trap 100 from the attracting port 22 beyond the annular edge part 23. The flying pest that has entered the attracting port 22 is captured by the flying pest trap 100 by dropping onto the tray unit 10.

  0.1-5 mm is preferable and, as for the protrusion height from the outer surface of the cover part 20 of the cyclic | annular edge part 23 and the linear edge part 24, 1-3 mm is more preferable. When the projecting 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 projecting amount is insufficient, and thus the flying edge pest and the linear edge portion 23 and the linear shape are moved during the movement. There exists a possibility that it will remove | deviate from the edge part 24 and it cannot guide to the invitation port 22. FIG. When the projecting 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 attracting opening 22 is increased. Even if a pest approaches the vicinity of the attracting port 22, there is a possibility that it cannot move to the inside of the flying pest trap 100. 0.5-5 mm is preferable and the width | variety of the annular edge part 23 and the linear edge part 24 has more preferable 1-3 mm. When 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 flying insects do not easily stop at the annular edge portion 23 and the linear edge portion 24 and cannot be guided to the attracting port 22. There is a fear. When the width of the annular edge portion 23 and the linear edge portion 24 exceeds 5 mm, the flying pests that have stopped on the annular edge portion 23 and the linear edge portion 24 are likely to stay on the spot and may not be able to be guided to the induction port 22. . The annular edge portion 23 and the linear edge portion 24 may be chamfered or rounded. In this case, since the flying pests that have stopped on the outer surface of the lid portion can easily cross the step due to the annular edge portion 23 or the linear edge portion 24, particularly about the flying pests that have attracted around the induction port 22. It becomes easy to fall to the attracting port 22, and the capture effect can be enhanced.

  3 and 5 exemplify the annular edge portion 23 and the linear edge portion 24 as the carnivorous plant mimicking structure, but the carnivorous plant mimicking structure is constituted only by the annular edge portion 23 or the linear edge portion 24. It is also possible. For example, if a large number of fan-shaped induction openings 22 are formed radially around the top part P of the lid part 20 and the annular edge part 23 is formed so as to surround the radial induction openings 22, the linear edge part 24 is not provided. However, the flying pest can be attracted to the attracting 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 induction port 22 of the lid portion 20, the flying pests can reach the induction 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 flying pest attracting effect and capturing effect due to a synergistic effect with the attracting agent contained in the drug portion 30 accommodated in the tray portion 10. it can. That is, since the attractant contains a scent component derived from the flying pest attracting plant, the flying pest trap 100 of the present invention is coupled with the carnivorous plant mimicking structure of the annular edge portion 23 and the linear edge portion 24. Will be more imitating carnivorous plants. For this reason, it is possible to reliably attract and capture the flying pests inside the flying pest trap 100 without giving a warning to the flying pests.

  Thus, the flying insect trap 100 of the present invention is a biomimetic type flying insect trap imitating a carnivorous plant, which is a completely new type of innovative insect repellent product that has never existed before. .

[Capture test 1: Confirmation of effect by carnivorous plant mimicking structure]
Using the flying insect trap having the carnivorous plant mimicking structure of the present invention, a capture test was carried out on Drosophila, which is a typical flying insect. Moreover, the same test was performed also about the flying insect trap which does not have a carnivorous plant imitation structure, and it compared with the result of the flying insect trap of this invention. The specifications of the flying insect 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 attracting openings were formed in the lid, and the total opening area of the attracting openings was 1000 mm ² . Furthermore, the lid portion was formed with an annular edge portion surrounding the induction port and a linear edge portion connected to the annular edge portion. The tray was provided with a drug part in which a chemical solution was soaked in felt (length 50 mm × width 50 mm × thickness 20 mm). The chemical solution contains balsamic vinegar and tri-sugar 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 opening but not having a linear edge portion was used. Other configurations were the same as those of the flying insect trap of Example 1.

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

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

As a procedure of the capture test 1, first, about 300 Drosophila were released in 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 center floor of the test room. After one day, the number of Drosophila captured in the flying pest trap was counted. This capture test was repeated three times, and the average number of captured insects was calculated. The results of capture test 1 are shown in Table 1.

  In the flying pest traps of Examples 1 to 3, in which the annular edge portion and / or the linear edge portion were formed on the lid portion, the average number of trapping insects was about 100 or more. In contrast, the flying insect trap of Comparative Example 1 in which neither the annular edge portion nor the linear edge portion was formed on the lid portion had an average number of trapping insects of about 50. As described above, the flying pest trap having the carnivorous plant mimicking structure has a trapping effect about twice as large as that of the flying pest trapping apparatus not having the carnivorous plant mimicking structure, and the flying pest trap of the present invention. Was confirmed to be an excellent insect repellent product.

[Capture test 2: Confirmation of effect by fragrance component derived from flying insect attractant plant]
In the flying pest trap having the annular edge portion and the linear edge portion used in Example 1, in place of the chemical solution used in Example 1, fragrance components derived from flying pest attractant plants, dinotefuran, glycerin, and others A capture test 2 was carried out in the same procedure as the capture test 1 using a chemical solution containing components (purified water, etc.) soaked in the drug part. The results of capture test 2 are shown in Table 2. In addition, about the fragrance component derived from the flying insect attractant plant of each Example shown in Table 2, phenyl ethyl alcohol (Example 4), methyl butyrate (Example 5), alpha-pinene (Example 6), And osymene (Example 7) are derived from plants belonging to the genus Tennansho, methyl salicylate (Example 8) and benzaldehyde (Example 9) are derived from plants of the genus Tulip, and jasmine lactone (implemented) Example 10) and indole (Example 11) are derived from a plant belonging to the genus Sokei.

  Each of the flying insect traps of Examples 4 to 11 in which the scent component derived from the flying insect attractant plant is contained in the chemical solution has an average number of trapping insects of about 100 or more, and balsamic vinegar and trithermal sugar as attractants. A trapping effect equivalent to or higher than that of the flying pest traps of Examples 1 to 3 in which is added to the chemical solution was observed. In particular, the flying insect pest catchers of Examples 4 to 7 using fragrance components derived from plants belonging to the genus Tennansho had an average number of trapping insects of about 150 or more, and a very remarkable capturing effect was recognized. This is considered to be due to the synergistic increase in the effect of attracting flying insects in combination with the carnivorous plant mimicking structure formed on the lid, since the Tennansho spp. Plant is a kind of insect medium flower.

  The flying insect trap of the present invention can be suitably used for fly insects such as Drosophila, flea flies, mushroom fly, mushroom fly, butterfly, etc. It can also be used against flies.
