Description

The present invention relates to a bait station structure for insects of the family Vespidaceae. More specifically, the present invention relates to a Vespidaceae insect bait station structure having a structure that allows Vespidaceae insects to enter and exit, and a container used for the structure, for the purpose of exterminating the Vespidaceae insects together with the nest.

In everyday life, flying organisms sometimes harm human life. For example, Lymantria disparata occurs in various places, interrupting soccer games and damaging crops. So-called mosquitoes such as Aedes albopictus become hosts for pathogens such as dengue fever-causing bacteria and rage.
The same is true for Vespid insects. Hold the needle and attack. When stabbed, it may cause severe pain and swelling. Some species are poisonous, and many deaths from anaphylactic shock have been reported. As countermeasures, a method of killing insects with an aerosol (Japanese Patent Laid-Open No. 2008-156235; Patent Document 1) and a killing device (Registered Utility Model No. 3201021; Patent Document 2) are known.

For other insects, a method using poison bait has also been proposed, and a bait station aimed at exterminating the entire nest of insects has been commercialized. A bait station is a container that can avoid rain and wind, is easy to install, and is easy for target pests to enter and exit, and contains a poison bait containing a pest-attracting component and an insecticidal component.
For example, in ants, a product that exterminates nests by carrying poisonous bait containing insecticidal ingredients to the nest has been commercialized by Sumitomo Chemical Garden Products Co., Ltd. under the name "Ariator House". As for wasps, the idea of bringing back poisonous bait to worker bees to exterminate the nest has been known for a long time (Japanese Patent Laid-Open No. 2002-47106; Patent Document 3), but when the poisonous bait is liquid, a container is used so that it can easily enter and exit. If not devised, the individual would die in the container, and there was a problem that the poison bait could not be brought back to the nest. However, if the doorway is enlarged to make it easier to get in and out, there are still problems such as the food becoming dry and dust getting in easily.
The poison bait for the bait station of Vespidaceae insects can be prepared by mixing a slow-acting insecticidal component with a known inducing component for Vespidaceae insects (for example, mealworm, krill, fish meal, etc. (Patent Document 3)).

Japanese Unexamined Patent Publication No. 2008-156235 Registered Utility Model No. 3201021 JP-A-2002-47106

An object of the present invention is to provide a bait station structure using a container having a structure in which a hornet insect can easily bring a poisonous bait containing an insecticidal component back to the nest (a structure that easily enters and exits the container).

As a result of diligent studies to solve the above problems, the present inventors have completed the present invention by forming a structure that assists the exit of Vespid insects (exit assist structure) between the entrance and exit of the wasp and the bait. ..

That is, the present invention provides the following 1-5 bait station structures and containers for Vespid insects.
[1] A bait station structure for Vespid insects, which contains a poisonous bait containing a Vespid insect attracting component and an insecticidal component, and has an opening through which Vespid insects can enter and exit and a structure that assists the exit (exit assist structure). ..
[2] The bait station structure for Vespid insects according to item 1 above, wherein the Vespid insect exit assisting structure has a length that reaches the poison bait from an opening and a structure that serves as a foothold for the Vespid insects to walk.
[3] The bait station structure for insects of the family Vespidus according to item 2 above, wherein the structure serving as the scaffold is a mesh tubular body whose cross section coincides with (aligns with) the opening and whose length reaches the poison bait.
[4] The bait station structure for a hornet family insect according to any one of the above items 1 to 3, wherein the hornet family insect is a hornet subfamily insect or a paper wasp subfamily insect.
[5] A container having an opening through which Vespidaceae insects can enter and exit, and a structure for assisting the exit of Vespidaceae insects having a length that reaches the food storage portion from the opening.

The present invention provides a bait station structure for Vespid insects in which a poisonous bait containing a Vespid insect attracting component and an insecticidal component is housed in a container having an opening through which Vespid insects can enter and exit and an exit assisting structure. Since the Vespids insects that have entered the container leave the container without dying, it can be expected that the Vespids insects will be exterminated together with the poison bait brought back by the Vespids insects.

It is a perspective view of the container example containing the liquid poison bait used for the bait station structure for the hornet insect of this invention. It is a side view of the container of FIG.

The present invention targets insects belonging to the subfamily Vespidaceae and Polistes subfamily inhabiting Japan among the insects belonging to the family Vespidaceae.
Those belonging to the subfamily Vespinae, which belongs to the Hymenoptera hornets family, are divided into four groups: hornets, hornets, hornets, and provespa. 16 species of 3 genera inhabit Japan.
There are 11 species of 3 genera inhabiting Japan, which belong to the family Vespidaceae, Polistes jokahamae, and Polistes jokahamae, Polistes jokahamae, Polistes jokahamae, and Polistes jokahamae.

The bait station structure for Vespidaceae insects according to the present invention includes an opening through which Vespidaceae insects can enter and exit, and a structure that assists the exit of Vespidaceae insects (sometimes abbreviated as "exit assist structure"). It is used by storing a poisonous bait containing an insect-attracting component and an insecticidal component of the Vespidaceae family in the lower part of the container.

The container used in the present invention is provided with a hole (opening) through which Vespidaceae insects can enter and exit, and has a structure (exit assist structure) for assisting the exit of Vespidaceae insects reaching from the opening to the food storage portion. ..
The shape of the hole (opening) for the hornet insects to enter for food, hold the food, and exit is not particularly limited, but the size that large hornet insects such as giant hornets can enter and exit, for example, 2 cm or more in diameter. A hole having a size that allows large hornet insects to enter and exit, such as a circular hole and a square hole having a side of 2 cm or more, is preferable.

Next, a container for storing food will be described.
Examples of the material of the container include metals, plastics, ceramics and the like, but plastic is preferable in consideration of ease of processing and the like.
The color of the container is not particularly limited, and examples thereof include yellow, black, brown, green, and orange, and yellow and black are preferable.
The size of the container is not particularly limited, but if it is too small, there is a problem that the space for installing the food is insufficient, and if it is too large, the installation place is limited. Therefore, for example, the internal volume is about several tens to several hundreds of mL, preferably 100. ~ 500 mL.

A feature of the container used in the present invention is that it has an exit assisting structure that helps Vespidaceae insects that have entered the container in search of food to hold the food and reliably exit the container.
The exit assist structure is not particularly limited as long as it has a length that reaches the poison bait stored in the bottom of the container from the opening and a structure that serves as a scaffold for the hornet insects to walk. Hereinafter, as a preferred embodiment, an example of a cylindrical body having a cross section that matches (matches) the opening and a length that reaches the bait contained in the container will be described with reference to the drawings. FIG. 1 shows a perspective view of a state in which a liquid bait 3 is housed in a container 1 of the present embodiment in which a tubular body 2 having an exit assist structure is a net, and FIG. 2 shows a side view of FIG. In this example, Vespid insects can move up and down only inside the cylinder inside the container, but cannot move outside the cylinder.

The tubular body serves as a scaffold on which the hornet insects holding the food in the containment can easily walk to the opening.
Vespid insects fly like common insects and can walk on easy-to-walk surfaces. For example, it is considered difficult to walk on a smooth surface such as metal or glass. On the other hand, leather, cloth, wood, non-smooth resin surface, mesh (net), etc. have irregularities that serve as scaffolding for walking, and it is considered that walking can be easily performed on the surface. Therefore, the material of the tubular body may be any material having an uneven surface or an uneven structure on which the wasp serves as a scaffold for walking, and is not limited to the mesh structure, but in the case of the mesh tubular body, the lower part of the container. The liquid poison bait contained in the cylinder can freely move (flow) into the tubular body. The material of the tubular body is preferably made of plastic in consideration of ease of manufacture and durability.

Vespid insects can be attracted to the inside by putting the food preferred by Vespid insects in the container. Mix poison (insecticide) in the bait. Vespid insects have a habit of exchanging food (distribution of food) in the form of mouth-to-mouth when returning to the nest, so it can be expected that the nest will be exterminated using this modification.

In the present invention, the poison bait contained in the container is composed of an attracting component and an insecticidal component.
The attracting component is not particularly limited, but for example, essential oils, sugars, dairy products, flavors, alcohols, liquids containing acetic acid fermented products, fruit juices and the like can be used alone or in admixture of two or more. These can be used as a liquid or mixed with a gelling agent such as agar, guar gum or sodium polyacrylate, or a thickener to be used as a gel or a solid.
In addition, solids such as meat, fish, cat food, insect jelly, and living organisms (grasshoppers, crickets) can also be used as attracting components (food components).

An insecticidal component is mixed with the above-mentioned attracting component to make a poison bait.
Examples of the insecticidal component include permethrin ((3-phenoxybenzyl = (1RS, 3RS)-(1RS, 3RS) -3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate)) and cibelmethrin. ((RS) -α-cyano-3-phenoxybenzyl = (1RS, 3RS)-(1RS, 3RS) -3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate), fenvalere Ate (α-cyano-3-phenoxybenzyl-2- (4-chlorophenyl) -3-methylbutanoate), dinotefuran ((RS) -1-methyl-2-nitro-3- (tetrahydro-3-furylmethyl) ) Guanidin), viceroid (cyano (4-fluoro-3-phenoxyphenylmethyl-3- (2,2-dichloroethenyl) -2,2-dimethylcyclopropanecarboxylate), CYAP (O, O-dimethyl-O) -P-cyanophenyl = thiophosphate), DMTP (O, O-dimethyl-S [5-methoxy-1,3,4-thiadiasol-2 (3H) onyl- (3) -methyl] dithiophosphate), BRP ( Dimethyl-1,2-dibrom-2,2-dichloroethyl phosphate), salithione (2-methoxy-4H-1,3,2-benzodioxaphosphorin-2-sulfide), DDVP (dimethyl 2,2-di Chlorvinyl phosphate), Sumithion (MEP), (O, O-dimethyl-O- (3-methyl-4-nitrophenyl) thiophosphate), clothianidin ((E) -1- (2-chloro-1,3-) Thiazol-5-ylmethyl) -3-methyl-2-nitroguanidine), Marathon (S- [1,2,-bis (ethoxycarbonyl) ethyl] dimethylphosphorothiolthionate), dimethate (dimethyl S- (N-) Methylcarbamoylmethyl) dithiophosphate), Elsan (S- [α- (ethoxycarbonyl) benzyl] dimethylphosphorothiolthionate), Bygit (O, O-dimethyl-O- (3-methyl-4-methylthiophenylthiophosphate) )), Bassa (O-sec-butylphenylmethylcarbamate), MTMC (m-tolylmethylcarbamate), Meopal (3,4-dimethylphenyl-N-methylcarbamate), NAC (1-naphthyl-N-methylcarbamate) , Mesomil (S-methyl-N [(methylcarbamoyl) oxy] thio Acetimide), Cartap (1,3-bis (carbamoylthio) -2- (N, N-dimethylamino) propanehydrochloride) and the like, but are not limited thereto.
Further, if desired, a conventional solvent, an antifreeze agent, an antifoaming agent, a preservative, an antioxidant, a thickener and the like, which are used when preparing a preparation such as an insecticide, can be appropriately added.

Hereinafter, the present invention will be described in more detail with reference to Examples, Comparative Examples and Test Examples, but the present invention is not limited to these examples. The members used in the examples and comparative examples are as follows.

(2) Netron protector C-16, black: manufactured by Dainippon Plastics Co., Ltd. (hereinafter referred to as "ami cylinder")
(3) Yakult (registered trademark) 400: Made by Yakult Honsha Co., Ltd.

Example 1:
A hole with a diameter of 3.2 cm was made in the center of the plastic cup lid, and the ami cylinder was cut to a length of 10 cm and passed through the hole in the plastic cup lid. A container in which 200 mL of Yakult 400 was placed as bait (attracting component) in a plastic cup and covered with a lid was used as the container of Example 1.

Comparative Example 1:
A container from Example 1 excluding the ami tube, that is, a container without a scaffold was used as the container of Comparative Example 1.

Test Example 1:
A test comparing the container of Example 1 having an exit assisting structure as a scaffold for walking insects of Vespidus and the container of Comparative Example 1 without a scaffold was carried out as follows.
The containers of Example 1 and Comparative Example 1 were placed in separate plastic containers having a width of 32 cm, a depth of 17 cm, and a height of 25 cm, respectively. One vespa analis was released into a plastic container, and the number of times it entered and exited the container of Example 1 or Comparative Example 1 was confirmed. In this test, confirmation was continued for 6 hours, and the total number of times was used as the test result.

In Test Example 1, in Example 1, invasion was observed 10 times in total of 2 repetitions, and all the invading individuals escaped. It was confirmed that all the escaped individuals were feeding.
On the other hand, in Comparative Example 1, the total number of times of entry and exit is as small as 2 times of entry and 1 time of escape, but in Repeat 1, the number of times of entry and exit is small because it takes 5 hours to enter and escape by the 1st hour. In Repeat 2, he entered by the first hour and could not escape. This individual was confirmed dead in the container the next day (drowning with liquid food).
From Test Example 1, it can be understood that the container of the present invention has a structure in which hornet insects can easily enter and exit (enter / exit).

Test Example 2:
A large giant hornet was tested in the same manner as in Test Example 1 using only the container of Example 1 (with scaffolding). The results are shown in Table 2.

In Test Example 2, the giant hornet, which is a large hornet, was also found to enter 6 times in total for 2 repetitions as in Test Example 1, and all the invaded hornets escaped. Therefore, it was confirmed that the scaffolding system (exit assist structure) of the container of Example 1 was suitable for large hornet insects. It was confirmed that all the escaped individuals were eating.

Test Example 3:
The same test as in Test Example 1 was carried out for Polistes jokahamae using only the container of Example 1 (with scaffolding). In Test Example 3, the number of animals was increased to 10. The results are shown in Table 3.

In Test Example 3, the paper wasp, Polistes jokahamae, was also found to enter 31 times in total, and all of them escaped. Therefore, it was confirmed that the scaffolding system (exit assist structure) of the container of Example 1 can be applied to the paper wasp subfamily insects. It was confirmed that all the escaped individuals were eating.

Test Example 4:
The same test as in Test Example 3 was carried out for paper wasps using only the container of Example 1 (with scaffolding). The results are shown in Table 4.

In Test Example 4, the paper wasp, a paper wasp, was also found to enter 17 times in total, and all of them escaped. Therefore, it was confirmed that the scaffolding system (exit assist structure) of the container of Example 1 can be applied to two species of Polistes subfamily. It was confirmed that all the escaped individuals were eating.

The present invention provides a container with an opening through which Vespidaceae insects can enter and exit, and a container with an exit assist structure (scaffold) that allows Vespidaceae insects holding food to easily walk and move to the opening. It can be expected that the whole nest of Vespids insects will be exterminated by the Vespidaceae insect bait station.
