However, in the above-described flying insect traps, including conventional flying insect traps, flying insects that have once entered the container due to the attracting action of the attractant pass through the attracting hole of the container and escape to the outside. could not prevent it.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a flying pest extermination device capable of reliably exterminating flying pests that have been lured into a container without escaping to the outside. do.

The characteristic configuration of the flying pest exterminator according to the present invention for solving the above problems is as follows:
A flying pest exterminator that attracts and exterminates flying pests,
a tray portion containing an attractant;
a lid portion having an attraction hole for the flying pest and attached to the tray portion;
with
A collision plate with which the flying pests that have entered from the attracting holes collide is vertically provided downward from the top surface of the lid.

According to the flying pest extermination device of this configuration, the impact plate on which the flying pests collide is vertically provided downward from the top surface of the lid, so that the flying pests are attracted by the attractant exterminator contained in the tray portion. The flying pest collides with the collision plate when it enters through the attracting hole. Flying pests that collide with the impact plate fall directly into the attracting and exterminating agent in the tray portion and can be exterminated. In addition, when the flying pest that has entered through the attracting hole does not collide with the impingement plate and attempts to escape, the impingement plate acts as a barrier to prevent the flying pest from passing through.

In the flying pest exterminator according to the present invention,
It is preferable that the top surface of the lid portion is non-porous.

According to the flying pest extermination device of this configuration, when a flying pest that has entered through the attracting hole stops on the impact plate, the flying pest has a habit of moving against gravity when it lands on the barrier, so it climbs up the impact plate, try to escape outside. However, since the top surface of the lid is non-porous, flying pests cannot escape to the outside, and can then be attracted and exterminated by the attractant-exterminating agent in the tray.

In the flying pest exterminator according to the present invention,
Preferably, the collision plate comprises a plurality of radially extending collision plates.

According to the flying pest exterminator of this configuration, the impingement plate is composed of a plurality of impingement plates extending radially, so that the impingement plates are oriented in different directions, and the flying pests flying from different directions hit the impingement plate. can increase the probability of colliding with

In the flying pest exterminator according to the present invention,
It is preferable that the tray part has a columnar part protruding upward by 10 mm or more from the surface of the attractant-repellent.

According to the flying pest exterminator of this configuration, since the tray part is configured to have a columnar part that protrudes upward by 10 mm or more from the surface of the attractant extermination agent, the columnar part does not allow flying pests entering from the attracting hole. It functions as a perch for pests. Since flying pests have a habit of perching on a perch, they can perch on the column and then be attracted by the attractant-killer in the tray and exterminated.

An embodiment of a flying pest exterminator of the present invention will be described below with reference to FIGS. 1 to 5. FIG. However, the present invention is not intended to be limited to the embodiments described below or the configurations described in the drawings.

〔overall structure〕
A flying pest exterminator 1 is a device for attracting and exterminating flying pests. The flying pests to be exterminated by the exterminator 1 are not particularly limited, but examples thereof include fruit flies, flea flies, and mushroom flies. The flying pest exterminator 1 includes a tray portion 20 and a lid portion 30. - 特許庁As shown in FIG. 1, the flying pest extermination device 1 is integrated by attaching a lid portion 30 to a tray portion 20 to constitute the flying pest extermination device 1 . The tray section 20 and the lid section 30 will be described in detail below.

<Tray part>
The tray part 20 accommodates the attractant repellent 21, as shown in FIG. 1(a). The tray part 20 is a container with a bottom and has a cup shape. The material constituting the tray part 20 is not particularly limited as long as it does not degrade the attractant repellent 21 accommodated inside the tray part 20 and the tray part 20 is not subject to deterioration, erosion, corrosion, etc., but for example , polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polypropylene (PP), polyethylene (PE), polystyrene (PS), and the like. When a resin material is used as the constituent material of the tray portion 20, the tray portion 20 can be produced by a molding method such as injection molding.

The attractant-killer 21 is composed of an open-celled foam having small pores on the surface through which flying pests enter. Flying pests have a burrowing habit and thus burrow into open cell foams. Since the open-cell foam is impregnated with a flying insect-attracting component and an insecticidal component, when the open-cell foam is infiltrated and comes into contact with it, the action of the insecticidal component and the wetness of the wings, etc., make it incapable of action and extermination. can be done. The flying pest-attracting component can attract flying pests, and the insecticidal component can improve the effect of exterminating flying pests.

The open-cell foam is made of open-cell foam made of synthetic resin such as polyurethane resin or polyolefin resin, and has a large number of small pores on the surface thereof through which flying pests can enter. For the small holes, the open cells that are naturally formed when the open-cell foam is produced can be used as they are. can also The size of the small hole is preferably such that a flying pest that has entered the small hole cannot rotate and escape from the small hole. .5 to 2 mm, 2 to 5 mm, etc. can be selected as appropriate.

The component for attracting flying insects is not particularly limited, and conventionally known attracting agents for flying insects can be appropriately used. In addition to ingredients extracted from animals, acetic acid, alcohol, milk and oil, preservatives such as sorbic acid can be appropriately blended and used as necessary.

The insecticidal component is not particularly limited, and conventionally known insecticidal components can be used as appropriate. , pyrethroids such as bifenthrin, and other insecticidal components can be used. Among these insecticidal ingredients, dinotefuran, which is a neonicotinoid, is particularly preferred because it has low repellency against flying insects and does not inhibit the attracting action of the component that attracts flying insects.

As shown in FIG. 1( a ), it is preferable that the tray part 20 has a columnar part 22 that protrudes upward from the surface of the attractant remover 21 by 10 mm or more. Although the columnar portion 22 is formed in a truncated cone shape in this embodiment, it may be formed in a truncated pyramid shape. The columnar part 22 protrudes upward by 10 mm or more from the surface of the attractant-killer 21, so that it functions as a perch for flying insects that have entered through the attracting hole inside the exterminator 1. Flying pests have a habit of perching on a perch, so they perch on the columnar portion 22 . By stopping on the columnar part 22, the flying pest stays in a position close to the attractant-killer 21, so that it is easily affected by the flying insect-attracting component and the insecticidal component contained in the attractant-killer 21. - 特許庁Therefore, it is finally attracted by the attractant exterminator 21, and the flying pest can be exterminated.

The tray portion 20 is integrally provided with a flange portion 23 that engages with the lid portion 30 . Before use, for example, a film (not shown) formed by laminating an aluminum layer and a resin layer is attached to the flange portion 23, and the inside is sealed to prevent the attractant exterminator 21 from transpiration. can be done. At the time of use, the film is peeled off from the flange portion 23 and the lid portion 30 is attached.

<Lid>
As shown in FIGS. 1 to 3, the lid portion 30 has holes 31 for attracting flying pests and is attached to the tray portion 20 . When a resin material is used as the constituent material of the lid portion 30, the lid portion 30 can be produced by a molding method such as injection molding. The lid part 30 introduces outside air into the flying pest exterminator 1 through the attracting hole 31 and diffuses the flying pest attracting component impregnated in the attracting exterminator 21 to the outside.

As shown in FIGS. 1 and 2, the attraction hole 31 has a circular attraction hole 31a and a semicircular attraction hole 31b. As shown in FIG. 2( a ), the guide holes 31 are provided in a plurality of positions that are point-symmetrical about the vertex P of the lid portion 30 . By providing a plurality of attracting holes 31 around the flying insect exterminator 1, the flying insect attracting component impregnated in the attracting exterminator 21 can be evenly diffused. The shape of the attracting hole 31 may be an arbitrary shape, such as a square shape, a star shape, a heart shape, etc., as long as the flying pest can enter.

As shown in FIG. 1( a ), the lid portion 30 has a collision plate 32 against which flying insects that have entered from the attracting holes 31 collide. The collision plate 32 is provided integrally with the lid portion 30 and configured to extend downward from the top surface of the lid portion 30 . When flying pests are attracted by the attracting and exterminating agent 21 housed in the tray part 20 and enter through the attracting holes 31, the impact plate 32 functions as a flight intercept trap, and the flying pests collide with the impact plate 32. - 特許庁Here, the flight intercept trap is a trap that utilizes the fact that a flying pest hits an obstacle and falls down. Therefore, the flying pests that have collided with the impact plate 32 fall on the attractant-repellent agent 21 of the tray part 20 and can be exterminated. Further, when the flying pest that has entered through the attracting hole 31 does not collide with the impingement plate 32 and tries to go outside, the impingement plate 32 acts as a barrier to prevent the flying pest from passing through. It can be exterminated without escaping.

The collision plate 32 is preferably composed of a plurality of radially extending collision plates 32, as shown in FIG. 2(a). In this embodiment, as shown in FIG. 2A, four collision plates 32 are formed in a cross shape, but the number of collision plates is not particularly limited. By directing the collision plate 32 in different directions, it is possible to increase the probability that flying pests flying from different directions collide with the collision plate 32. - 特許庁

As shown in FIG. 2(a), the lid 30 preferably has a non-porous top surface. When a flying pest that has entered through the attracting hole 31 stops on the collision plate 32, it becomes a Malaise trap. Here, the Malaise trap is a trap that utilizes the property that when a flying pest lands on a barrier, it moves upward against gravity. Therefore, the flying pest that has landed on the collision plate 32 climbs up and tries to escape to the outside. However, since the top surface of the lid portion 30 is non-porous, flying pests cannot escape to the outside, and can then be attracted and exterminated by the attracting and exterminating agent 21 .

The lid portion 30 includes a connection portion 33 that engages with the flange portion 23, as shown in FIG. 2(c). The connecting portion 33 is configured in a shape that can be engaged with the flange portion 23 of the tray portion 20 . In this embodiment, three connecting portions 33 are provided, but the number is not particularly limited. Although it is preferable that the connection portion 33 can be easily attached to and detached from the flange portion 23 by engaging a projection or the like, it is also possible to screw the connection portion 33 into the flange portion 23, for example. When the connecting portion 33 on the lid portion 30 side and the flange portion 23 on the tray portion 20 side are engaged with each other, the flying pest exterminator 1 is ready for use.

In this embodiment, as shown in the enlarged view of part A of FIG. When the lid portion 30 is pushed into the tray portion 20, the lid portion 30 is elastically deformed so as to open outward while the connection portion 33 is in contact with the flange portion 23, and when the flange portion 23 climbs over the connection portion 33, the lid is elastically deformed. The portion 30 is restored to its original shape, and the flange portion 23 and the connecting portion 33 are fitted. Conversely, when the lid portion 30 is pulled out from the tray portion 20, the lid portion 30 is elastically deformed and removed. As described above, since the lid portion 30 can be easily attached to and detached from the tray portion 20, when the flying pest attracting component and the insecticidal component transpire from the attractant-killer 21 and the effect of exterminating flying pests is reduced, the tray can be removed. Reusing the tray part 20 and the lid part 30 by removing the attractant-eliminator 21 housed in the part 20 and installing a new attractant-eliminator 21 impregnated with a flying insect attracting component and an insecticidal component. can be done.

Using the flying pest extermination device of the present invention, a trapping test was conducted for Drosophila, a typical flying pest. A similar test was also conducted on a flying pest extermination device without a collision plate, and the results were compared with those of the flying pest extermination device of the present invention. The specifications of the flying pest exterminator used in the capture test are as follows.

An orange opaque lid and a colorless transparent tray were produced by injection molding of polypropylene resin. Nine circular induction holes and three semicircular induction holes were formed on the side surface of the lid. The top surface of the lid is non-porous. Further, a collision plate is integrally formed on the lid portion so as to extend downward from the top surface of the lid portion. In the tray portion, an attractant-extinction agent in which an open-cell foam was impregnated with a flying insect-attracting component and an insecticidal component was installed. Here, dinotefuran was used as the insecticidal component.

<Comparative Example 1>
As shown in FIG. 4, the lid was formed with induction holes on the top and side surfaces and did not have a collision plate. Other configurations were the same as those of the flying pest extermination device of Example 1.

As a procedure for the trapping test, first, about 100 Drosophila were released into a test room of about 25 m ³ , and the flying pest exterminators of Example 1 and Comparative Example 1 were placed on the central floor of the test room. After 24 hours, the number of Drosophila trapped inside each was counted.

Figure 5 and Table 1 show the test results of the capture test.

The flying pest exterminator of Example 1, which has a collision plate on the lid, captured 34 pests. On the other hand, the flying pest extermination device of Comparative Example 1, which does not have a collision plate on the lid portion, captured only 10 pests. As described above, the flying pest extermination device with the impingement plate has about three times the catching effect of the flying pest extermination device without the impingement plate, and the flying pest extermination device of the present invention is an excellent extermination product. It was confirmed that

The flying pest extermination device of the present invention can reliably exterminate flying pests that have invaded the container without escaping to the outside. It can also be used for exterminating other flying pests.
