Japanese Patent Application Laid-Open No. 2002-142643

On the other hand, in recent years, there has been a high tendency for users to be clean-minded about daily necessities, and even if a catcher is installed, it is as inconspicuous as possible, and a means for more effectively catching and controlling flying pests such as flies and flies flying around the room. Is desired to be provided.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to make it inconspicuous when the pest trap is installed in a room or the like, and to easily attract flying pests to the inside of the trap, effectively. The purpose is to provide a pest catching method and a pest catcher capable of catching and controlling.

The above object according to the present invention is achieved by the following configuration.
(1) A pest catching method in which a pest catcher containing an attractant in the main body of the catcher and having an entry port is used to attract and catch flying pests.
A pest trapping method in which the pest trap is installed on the wall surface so that the entrance formed on only one surface of the trap body faces the wall surface in the vertical direction of the structure at a predetermined distance.
Hereinafter, "installing a pest trap" means installing the pest traps facing each other at a predetermined distance from each other.
(2) The pest capture method according to (1) above, wherein the entrance is made to face the predetermined distance at a distance of 1 mm or more and 20 mm or less from the wall surface.
(3) A pest trap that houses an attractant in the trap body and has an entrance.
Have a installation interval retaining mechanism for installing the trap body are opposed to each other a predetermined distance to the penetration openings in the wall surface to the wall surface,
A pest trap in which the installation interval holding mechanism has a spacer provided between the surface of the trap body where the entrance is formed and the wall surface .
(4) A pest trap that houses an attractant in the trap body and has an entrance.
It has an installation interval holding mechanism for installing the trap body on the wall surface so that the surface of the trap body on which the entrance is formed faces the wall surface in the vertical direction of the structure at a predetermined distance. And
A pest trap in which the installation interval holding mechanism has a hook provided on the catcher main body and a fixing pin having a locking portion for locking the hook at a predetermined position and fixed to the wall surface .

According to the configurations (1) to (5) above, flying pests such as flies and flies walk along the wall surface facing the trap body in the gap between the wall surface and the pest trap, and enter the trap. By the action of the arranged attractant, it efficiently invades the trap through the entrance facing the wall surface. Since the entry port faces the wall surface on which the pest trap is installed, it is not necessary to form the entry port on the surface of the catcher body opposite to the entry port, and the pest catcher is inconspicuous.

Normally, when using a pest trap to capture and control flying pests such as flies and flies, point the entrance where the flying pests invade toward the space where the flying pests are flying. It is used for installation and pest traps are designed accordingly. In other words, it is thought that if a pest trap is installed with the entrance facing the space where the flying pests are flying, the flying pests will efficiently invade the entrance from the space, and it has been used as such.

However, according to the present inventor, by installing the pest catcher with the entrance of the pest catcher facing the wall surface at a predetermined distance, a large number of flying pests are found as compared with the usual case. I found that I could capture.

The distance between the entrance of the pest trap and the wall surface is preferably 100 mm or less, and particularly preferably 1 mm or more and 20 mm or less. However, the distance between the entrance of the pest trap and the wall surface may be a distance that allows flying pests to invade, and the lower limit is not limited.

The pest trap is preferably made of a material, color, and shape so that the surface facing the wall surface of the trap body having the entrance is darker than the peripheral portion. Further, the pest trap is preferably formed of a material having a translucent property (light-shielding property) such that a darker part than the peripheral part is formed on the wall surface facing the entrance and the portion near the entrance. A light-shielding member may be attached to the pest trap so that a darker part than the peripheral part is generated. By darkening the area around the entrance of the pest catcher, it is possible to attract and catch more flying pests such as flies and flies. It is presumed that this action effect is due to the habit that flying pests such as flies and flies prefer dark places when spawning and feeding.

The wall surface facing surface having the entrance of the catcher body does not necessarily have to be separated from the wall surface to be installed, and a part of the wall surface facing surface having the entrance port may be in contact with the wall surface. For example, when the pest trap is installed diagonally downward on the wall surface by bringing the upper end edge of the wall surface facing surface having the entrance of the trap body into contact with the wall surface, the flying pests traveling along the wall surface in the gap are higher than the pest trap. It becomes difficult to move to, and it becomes easy to enter the trap through the entrance.

As an installation interval holding mechanism for installing the catcher main body with a predetermined distance between the entrance of the catcher main body and the wall surface, for example, the surface and the wall surface of the catcher main body where the entrance port is formed are formed. A spacer is provided between the two (ie, at least one of the trap body or the wall surface). By providing such a spacer and fixing the trap body to the wall surface, a predetermined distance can be maintained between the spacer and the wall surface. To install a pest catcher, attach the catcher body to the wall surface, hang the catcher body on the wall surface, or pierce a pin to lock it to the wall surface.

Further, the installation interval holding mechanism having another configuration is composed of a hook provided on the trap body and a fixing pin having a locking portion for locking the hook at a predetermined position and being fixed to the wall surface. By locking the hook of the trap body to the locking portion of such a fixing pin, the trap body can maintain a predetermined distance from the wall surface.

The area of the entrance is preferably 0.4% or more, preferably 0.7% or more of the total surface area of the inner surface of the trap body. Further, it is preferably 5% or less, preferably 4.5% or less. The number of entrances may be one or more, but if the total area of the entrances is the same, the total length of the edges of the entrances will be longer for multiple entrances than for one. The longer the total rim length, the more chances that flying pests will reach the rim of the entry on the trap, and as a result, the more chances of entering the entry. Therefore, it is better to provide a plurality of small entrances than one large entrance.

The shape of the entrance is not particularly limited, but a polygonal shape having a long total edge length is preferable.
It is preferable that the catcher contains an insecticide and an adhesive in addition to an attractant that attracts flying pests.

The material of the trap body is preferably plastic, metal, or the like, but paper, pulp, cardboard, or the like may be used as long as it has water repellency and water resistance so that it can be installed even in a damp place. The catcher may have an internal volume capable of storing the necessary amount of the drug and the adhesive material in order to obtain the desired effect.

The entrance of the pest trap may be of a size and shape that allows flying pests to enter. There may be one or more entrances in the trap body, and they are provided continuously or intermittently on at least one surface of the trap body. The entrance may have a shape that narrows inward from the outer surface of the trap body.

The wall surface on which the pest trap is installed is, for example, a vertical wall surface in a structure such as a house, a room, a building, or a fence, but may be a wall surface rising from the bottom surface in a kitchen sink.
Further, the wall surface in the present invention does not include a floor surface and a ceiling surface.
Further, the wall surface in the present invention is not limited to the wall surface of the structure, and may be a simple plate member. In this case, a small plate member may be integrally formed with the trap body so as to face the entrance, or may be attached to the trap body so as to face the entrance.

Here, the basic capture mechanism of the pest trap of the present invention configured as described above will be described.

By installing the pest trap on the wall surface, the flying pests will detect the pest attracting component contained in the chemicals volatilized from the entry port and invade the inside of the catcher body from the entry port. I will go.

Then, the flying pests that have invaded the trap body come into contact with the insecticide, the adhesive, etc. contained in the trap body, and are killed or captured.

As the chemicals stored in the trap body, various shapes such as a sheet, a liquid, a granular, a gel, a jelly, and a solid can be used as appropriate.

The gel particles may have a spherical shape, a rod shape, a shape similar to these, or an indefinite shape such as a polygonal shape or a fragment shape, but when the gel particles are stored in the trap body, flying pests enter between the gel particles. It suffices if a gap to be obtained is formed. Further, the gel particles may have a uniform shape or a mixture of gel particles of different sizes, and the gel-like particles may be round or square.

In the case of a sheet, a carrier such as pulp paper may be impregnated with a chemical and held. Further, instead of the chemical, it can be used as an adhesive sheet by impregnating and applying an acrylic, rubber, silicon or other adhesive.
Further, an adhesive can be applied to the inner surface of the trap body and used.

Pest-attracting ingredients include, for example, Shokoshu, beer, wine, acetoin, fruit vinegar, brewed vinegar, grain vinegar, black vinegar, red vinegar, vinegar, various fruit extracts, fermented vegetables and fruits, miso, yeast, honey, etc. Examples thereof include liquid sugar, brown sugar, sugar, various vegetable or animal diets, and various attractive flavors.

In order to further enhance the control effect of flying pests, for example, insect repellent chrysanthemum extract, natural pyrethrin, prarethrin, imiprothrin, phthalthrin, aresulin, transfluthrin, resmethrin, phenotrin, ciphenotrin, permethrin, cypermesrin, etofemprox, cifluthrin, Pyrethroid compounds such as deltamesulin, bifenthrin, fenvalerate, fenpropasulin, empensulin, silafluofen, metoflutrin, profluthrin, organic phosphorus compounds such as fenitrothione, diadinone, marathon, pyridafenthion, prothiophos, hoxime, chlorpyriphos, dichlorovos, etc. Carbamate compounds such as mesomil and thiodicalve, oxaziazole compounds such as methoxadiazone, phenylpyrazole compounds such as fipronil, sulfonamide compounds such as amide flumeth, nicotinoid compounds such as dinotefuran and imidacloprid, metoprene, hydroprene, pyrethroids. Insect growth control compounds such as fen, and insecticidal essential oils such as orange oil, peppermint oil, and benzyl alcohol can also be used as insecticidal components.

Examples of other components include various auxiliary components such as an accidental ingestion preventive agent, a preservative, a pH adjuster, a stabilizer, a pigment, and a fragrance. For example, accidental ingestion inhibitors such as denatonium benzoate and capsicum extract, quaternary ammonium salts such as cetylpyridinium chloride, preservatives such as potassium sorbate and paraben, pH adjusters such as citric acid and phosphate salts, BHT. , Stabilizers such as BHA, various pigments indicating red, blue, yellow, green, black, brown, etc., fragrances such as melon, vanilla, strawberry, mango, apple, pear, banana, dorian, etc. Be done.

Examples of the flying pests to be the subject of the present invention include Drosophila simulaceae, Drosophila simulaceae, Drosophila simulaceae, Drosophila simulaceae, flies, Drosophila simulaceae, Drosophila simulaceae, green bottle flies, houseflies, butterfly flies, and mushroom flies.
Furthermore, the present invention is not limited to the above-mentioned flying pests, and the present invention can be applied to flying pests such as mosquitoes, bees, abs, and gnats (gnats).

According to the pest catching method and the pest catcher of the present invention, when the pest catcher is installed in a room or the like, it is inconspicuous and effectively attracts flying pests such as flies and flies to the inside of the catcher. Can be captured and controlled.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a pest trap according to an embodiment of the present invention.
The pest trap 10 includes a rectangular parallelepiped plastic resin trap body 12, an attractant 14 housed in the trap body 12, and an adhesive sheet 16 provided on the inner surface of the trap body 12. .. An entry port 18 for invading flying pests is formed on the wall surface facing surface 12a, which is one surface of the trap body 12. The entry port 18 is formed on the wall surface facing surface 12a so that the attractant 14 housed in the trap body 12 can be satisfactorily volatilized from the entry port 18. Cylindrical spacers 20 as an installation interval holding mechanism are provided at the four corners of the wall surface facing surface 12a, which is the surface on which the entry port 18 is formed. Then, by applying an adhesive to the end face 20a of the spacer 20 and attaching the spacer 20 to the wall surface 30 as shown in FIG. 2, the pest trap 10 is fixed to the wall surface 30. The adhesive is set to such an adhesive strength that the pest trap 10 can be appropriately removed from the wall surface 30. A gap S (predetermined distance) corresponding to the height T of the spacer 20 is secured between the wall surface facing surface 12a of the trap body 12 and the wall surface 30.

The catcher main body 12 has a thin box shape, and when installed on the wall surface 30, it does not protrude significantly toward the indoor side.

The flying pest is guided by the attractant 14 and travels along the wall surface 30 to reach the region of the gap S between the wall surface 30 and the wall surface facing surface 12a of the trap body 12. The flying pests are further attracted by the attractant 14 and fly or walk along to enter the trap body 12 through the entry port 18. The flying pests that have entered the trap body 12 come into contact with the adhesive sheet 16 in the process of moving toward the attractant 14, and are fixed to the adhesive sheet 16.

Further, by further accommodating the insecticide in the trap body 12 or by containing the insecticide in the attractant 14, the flying pests that have invaded the trap body 12 can be caused by the action of the insecticide. It leads to death.

According to the present inventor, by installing the pest trap 10 on the wall surface 30 with the entrance 18 formed in the trap body 12 facing the wall surface 30, the flying pests can be removed from the wall surface 30 and the trap body 12. It was found that the trap body 12 was efficiently invaded from the entrance 18 facing the gap S between the two. Conventionally, in order to catch flying pests, it is preferable to install the pest catcher 10 with the entrance 18 facing the space where the flying pests fly so that the flying pests can easily enter the trap body 12. Was thought to be. However, it was found that a larger number of flying pests can be captured by installing the pest trap 10 with the entrance 18 facing the wall surface 30 as in the present invention.

As in the pest trap 10A shown in FIG. 3A, the head of the pin 34 pierced into the wall surface 30 by a predetermined length by providing a hook 32 instead of providing the spacer 20 in the trap body 12. The hook 32 may be hooked on the hook 32. Further, the insertion length of the pin 34 can be regulated by fitting a cylindrical sleeve having a predetermined length in advance on the shaft portion of the pin 34 and then inserting the tip into the wall surface 30. In this case, the pest catcher 10A can be installed by simply suspending the pest catcher 10A on the wall surface 30 by securing a gap S between the wall surface facing surface 12a of the catcher main body 12 and the wall surface 30.

Further, as in the pest catcher 10B shown in FIG. 3B, a fixing pin 36 having a locking portion 38 for locking the hook 32 of the catcher body 12 at a predetermined position is pierced into the wall surface 30 and fixed. Then, the hook 32 may be hooked on the locking portion 38. In this case, the pest trap 10B is in a state where the fixing pin 36 is pierced into the wall surface 30 and the hook 32 is hooked on the locking portion 38 to secure a gap S in which the entrance 18 faces the wall surface 30 at a predetermined distance. The trap body 12 can be installed on the wall surface 30.

[Pest capture test]
In the Pete Grady chamber (length 1.8 m x width 1.8 m x height 1.8 m), one sample (example of the present invention) is placed 60 cm from the floor and 2 mm from the wall surface, and the entrance is placed on the wall surface. The entrance is directed toward the room (opposite wall surface) by sticking the surface of the other sample (comparative example) opposite to the entrance to the surface of the other sample opposite to the entrance. installed. As shown in FIG. 4, the sample has a flat container (capture body) having a pair of faces whose upper half is semicircular and whose lower half is rectangular. The dimensions of the inner surface of the container are as shown in FIG. A 1 cm × 3 cm mat filled with 1 g of an attractant made of Shaoxing wine, black vinegar, etc. was placed in the container. The entry port 18 was arranged on one surface of the container in a size of 5 mm × 30 mm, and the adhesive was arranged on the entire surface of the other surface of the container having no entry port. About 100 Drosophila melanogaster were released into the Pete Grady chamber, and the capture rate one day later was confirmed. The test was repeated 4 times. The results are shown in Table 1. The capture rate was calculated by using the total number of animals captured in each sample as a parameter.

As shown in Table 1, it was confirmed that the examples based on the pest capture method of the present invention had a capture rate more than twice that of the comparative examples. Therefore, it is more effective to install the pest trap entrance toward the wall surface than to install it indoors (anti-wall surface) in capturing flying pests.

[Effect of entrance area on container size 1]
In the Pete Grady chamber (length 1.8 m x width 1.8 m x height 1.8 m), four types of specimens with different opening areas of the entrance are placed 60 cm from the floor and 2 mm from the wall, and the entrance is placed on the wall. It was installed toward (see Fig. 5). As shown in FIG. 4, the sample has a flat container (capture body) having a pair of surfaces whose upper half is semicircular and whose lower half is rectangular. The dimensions of the inner surface of the container are as shown in FIG. In the container, a 1 cm × 3 cm mat filled with 1 g of an attractant made of Shaoxing wine, black vinegar, etc. was placed. The entry port 18 was arranged on one surface of the container, and the adhesive was arranged on the entire surface of the other surface of the container having no entry port. About 100 Drosophila melanogaster were released into the Pete Grady chamber, and the capture rate one day later was confirmed. The test was repeated 4 times. The results are shown in Table 2. The capture rate was calculated by using the total number of animals captured in each sample as a parameter.

As a result of the test, the capture rate of the sample having an entrance size of 10 mm × 30 mm was the highest. From this, it was found that when the ratio of the area of the entrance to the surface area of the inner surface of the container is 5% or less, the capture effect is excellent.

[Effect of entrance area on container size 2]
In a mesh cage (length 1 m × width 1 m × height 1 m), two types of specimens having different opening areas of the entry port were installed at a position 60 cm from the floor surface and 2 mm from the wall surface with the entry port facing the wall surface. As shown in FIG. 4, the sample has a flat container (capture body) having a pair of surfaces whose upper half is semicircular and whose lower half is rectangular. The dimensions of the inner surface of the container are as shown in FIG. In the container, a 1 cm × 3 cm mat filled with 1 g of an attractant made of Shaoxing wine, black vinegar, etc. was placed. The entry port 18 was arranged on one surface of the container, and the adhesive was arranged on the entire surface of the other surface of the container having no entry port. About 100 Drosophila melanogaster were released in the mesh cage, and the catch rate after 1 day was confirmed. The test was repeated 4 times. The results are shown in Table 3. The capture rate was calculated by using the total number of animals captured in each sample as a parameter. In addition, the test results in the Pete Grady chamber and the test results in the mesh cage can be treated equally.

As a result of the test, the larger the entrance, the higher the capture rate. From this, it was found that the capture rate increases when the ratio of the area of the entrance to the surface area of the inner surface of the container is 0.4% or more, and further 0.7% or more.

[Effect of entrance distance to wall surface]
In a mesh cage (length 1 m x width 1 m x height 1 m), four specimens were placed 0.5 mm, 1 mm, 20 mm, and 30 mm apart from the wall surface, respectively, and the entrance was placed at a position 20 cm from the floor surface with the entrance facing the wall surface. .. As shown in FIG. 4, the sample has a flat container (capture body) having a pair of surfaces whose upper half is semicircular and whose lower half is rectangular. The dimensions of the inner surface of the container are as shown in FIG. In the container, a 1 cm × 3 cm mat filled with 1 g of an attractant made of Shaoxing wine, black vinegar, etc. was placed. The entry port 18 was arranged on one surface of the container in a size of 10 mm × 30 mm, and about 100 Drosophila melanogaster were released into the mesh cage to confirm the catch rate one day later. The test was repeated 3 times. The results are shown in Table 4. The capture rate is an average value of the capture rates calculated using the number of animals captured in each sample as a population parameter for each of the three tests.

As a result of the test, the capture rate of the specimens having the predetermined distances of the entrance to the wall surface of 1 mm and 20 mm was high. From this, it was found that the capture rate increases when the predetermined distance of the entrance of the trap body to the wall surface is in the range of 1 mm or more and 20 mm or less.

The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

For example, the shape of the trap body does not have to be the thin box shape as described above, but may be another three-dimensional shape, or a three-dimensional shape imitating a living thing, a plant, a character, or the like.
Further, the trap may be fixed to the wall surface by a suction cup.

Further, the wall surface facing surface 12a having the entrance port 18 of the trap body 12 does not necessarily have to be separated from the wall surface 30 to be installed, and a part of the wall surface facing surface 12a having the entrance port 18 is in contact with the wall surface. May be good. For example, as in the installation mode of the pest trap 10C shown in FIG. 6, by hooking the hook 32 on the wall hook 39 fixed to the wall surface 30, the upper end edge of the wall surface facing surface 12a having the entrance 18 of the trap body 12 When the pest trap 10C is installed diagonally downward on the wall surface 30 by contacting the wall surface 30, flying pests traveling along the wall surface 30 in the gap become more difficult to move above the pest trap 10C and are captured from the entrance 18. It becomes easy to enter the vessel body 12.

Further, the pest catcher in the pest catching method of the present invention does not have to be installed on the wall surface, and may be hung on the ceiling or placed on the floor surface with the entrance facing the wall surface.

Further, the entrance of the catcher main body in the pest catcher of the present invention is formed on the surface facing the wall surface, but may be further formed on another surface of the catcher main body.
