Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a smoke control agent for controlling honeybee mites, Honeybee mite.
It relates to a smoke insect control agent.

[Conventional technology]

Conventionally, formulation forms called pest control agents, insecticides or insect repellents include emulsions used by diluting with water, oils diluted to a working concentration with an organic solvent, and usually solids such as powders, granules or tablets. When used, there are those used by dissolving in water or other solvents, powders or granules whose concentration is adjusted by using a powder or a powder of a mineral substance, solids adsorbed on combustibles, and various other types.

Here, some commercially available chemicals for controlling pests attached to beneficial organisms are diluted with water and sprayed, but in this method, the area to be controlled is flooded, and the desired drug effect is obtained. The harmful effects of humid conditions may be greater than in humid conditions. In addition, the selection or blending amount of the active ingredient and the like of the pest control agent is inappropriate, which adversely affects the beneficial organism, causing a conflict within the colony of the beneficial organism, The majority of drugs are causing damage to business owners by causing damage to the economic infrastructure, such as collapse. In addition, when using a controlling chemical, it may be necessary to separately separate the beneficial organism from the chemical, but the control of pests attached to the beneficial organism may be incomplete, In many cases, it is necessary to install a medicine in each of the target containers, and know that the damage by pests is large, but leave the necessary countermeasures in order to make each operation complicated.

For example, JP-A-48-52937 and JP-A-55-64735 or
Insecticides using the smoke method represented by the inventions disclosed in publications such as No. 56-12302 aim at complete killing of pests, particularly sanitary pests or crop pests, while benefiting organisms (for example, bees) ) Causes serious damages, such as the fact that they can be killed, and that they must be heated and used in a metal cylindrical container.

[Problems to be solved by the invention]

As described above, in the prior art, pests are effective and have no effect on beneficial organisms, and the selection of active ingredients when using them, measurement,
There is a problem that a smoke smoke pest control agent that is easy to mix and install is not yet obtained, and it has been an issue to solve this problem.

[Means for solving the problem]

In order to solve the above-mentioned problems, the present invention provides a composition comprising, by weight, cyphenothrin 0.01 to 2.0%, a flammable excipient 30 to 40%, a flame retardant 30 to 40%, a fragrance 0.05 to 0.2% and Means was adopted in which a composition comprising 30 to 60% of the flammable molding material was used as an agent for controlling smoke and insect pests for controlling honeybee mites. In addition, as a method for producing this smoke pest control agent, a uniform mixture of cyphenothrin with a flammable excipient, a flame retardant, and a fragrance is added. Filled so as to be evenly distributed between the molding materials, and molded into a shape having air permeability so that the molding material has a structure through which hot air can pass,
Further, in order to prevent the shape of the molded article from being deformed, a means of fixing the periphery with a cloth or paper adhesive tape or the like and then impregnating with a combustion aid such as paraffin can be adopted. The details are described below.

First, cyphenothrin, which is an insecticidal component in the present invention, is selected from the most suitable pyrethroid compounds capable of controlling only pests without affecting beneficial organisms by adjusting the dosage, and is parasitic on bees. For the purpose of controlling honeybee mites, 2.
Desirably, it is about 0 to 3.0 mg.

Next, the flammable excipients of the present invention include wood flour, paper flour, paper chips, wire, other ground plant powders and crushed pieces.

Further, the auxiliary agent of the present invention, various charcoal including activated carbon, wood wax, animal and vegetable fats and oils, paraffin, sulfur, tetracene, nitrates, nitrites, nitrocellulose,
And perchlorates.

In addition, the fragrance of the present invention is an essential component for calming the sway of beneficial animals, for example, menthol,
Various types of plant essential oils represented by cassia oil, cineol, jasmine, loin, etc., animal flavors, and powders of fruits, seeds, roots, branches, bark, leaves, flowers and the like of plants for flavoring.

Further, the flammable molding material of the present invention includes, in addition to cardboard pieces, bark, wood pieces, cloths, papers, polyvinyl chloride,
Synthetic or natural polymer substances such as nylon, polyethylene, paraffin, and wax, and adhesive tapes made of paper or cloth.

Here, the compounding ratio (weight%) of each of these components is 0.01 to 2.0% for cyphenothrin, 30 to 40% for a flammable excipient, 30 to 40% for a combustion aid, 0.05 to 0.2% for a fragrance, and 3
The reason for setting the content to 0 to 60% is that if the amount of each component is less than the lower limit, the expected effect cannot be obtained, and if the amount exceeds the upper limit, the effect of increasing the amount cannot be expected. .

In addition, in the present invention, when it is difficult to form a part or all of the constituent components, if the molding is difficult, the carboxy is used as a thickener (or a binder) in an amount of 5% or less. Methyl cellulose (CMC) or a derivative thereof, gum arabic powder, tragacanth powder, a substance containing a mucous component such as tab powder, a high-viscosity animal or vegetable oil or the like can also be added. Here, it is not preferable to add these thickeners in an amount of more than 5% because each effect of the other components is hindered.

When the above components are blended and formed into the insect pest controlling agent of the present invention, the insecticidal components are uniformly dispersed,
In addition, a sufficient amount of flammable excipient to produce smoke with uniform concentration, and an auxiliary agent to promote the smoke and maintain the heating source by maintaining the heating source so that the fire does not disappear on the way After mixing well with perfume for calming the behavior of beneficial organisms in the colony such as conflict, agitation, colony abandonment, etc., add a thickener if necessary, taking into account the binding state or viscosity of the mixture. Add. The obtained mixture is weighed according to the volume to be controlled, and the mixture is evenly dispersed and filled between combustible molding materials in consideration of air permeability. A specific method at this time is as follows. That is, a method in which the mixture is directly evenly dispersed and sandwiched between the flammable molding materials.

A method in which the mixture is filled into a thin plastic or paper bag, and the mixture is evenly dispersed in the bag and sandwiched between molding materials.

A method in which the mixture is mixed with a thickener and applied to the surface of a molding material.

And so on.

In this way, it is good to use molding materials of various shapes in accordance with the shape of a smoker to use a molding material in which an active ingredient is evenly dispersed, or to combine molding materials in consideration of air permeability. . Then, the surroundings are fixed with a cloth or paper adhesive tape or the like and impregnated with a combustion aid such as paraffin so that the obtained molded article does not lose its shape, thereby obtaining a desired smoke and insect pest control agent.

The product form of the smoke pest control agent of the present invention is not particularly limited to a rod, a tube, a perforated briquette, a sphere, a powder, a granule, and the like. The arbitrary shape and size may be determined according to the usage amount corresponding to the above. And in short, in the smoke pest control agent of the present invention, since the heat from the heating source needs to pass through the formed control agent, and the active ingredient must be in the state of smoke and guided to the target place. Regardless of the external shape, it is important to appropriately combine a flammable molding material so that the inside has a structure with good air permeability. In this way, only a small amount of burned-out ash remains after the use of the pesticide of the present invention, so that the post-finishing is extremely simple.

〔Example〕

Example: The following formulation was prepared as a smoke control agent against the honey beetle mites parasitic on bees.

Of the above ingredients, cyphenothrin, menthol,
Mix the sawdust, sulfur, activated carbon and part of the paraffin well, fill it evenly with the cardboard gap,
This is wound into a rod having a diameter of about 9 cm, the outer peripheral surface is reinforced with an adhesive tape so as not to lose its shape, and the remaining paraffin is melted and applied on the surface of the rod-shaped corrugated cardboard. A smoke insect control agent was obtained. A total of 80 g of this pesticide is made for 50 honeycomb boxes, cut into a sample of about 9 cm in diameter and about 3 cm in height for actual medicinal efficacy test,
Using regular smokers used by beekeepers, bees, pupae,
Smoke was pumped into the beehive with bee eggs inside. Smoke delivery In addition, two components of pyrethroids, ie, permethrin and phenothrin, were selected as control insecticidal components, and the medicinal effect with the cyphenothrin of the present invention (mite extermination rate%) and the medicinal effect of each insecticide on the honeybee, which is a host of the honeybee mite, Honeybee mite. That is, a comparison was made on phytotoxicity. Table 1 shows the obtained results. Where the tick removal rate
90-100% (A), 70-89% (B), 50-69% (C), 3
The evaluation was performed on a five-point scale of 0 to 49% (D) and less than 29% (E). The phytotoxicity was evaluated on a three-point scale: no phytotoxicity (-), slight phytotoxicity (±), and phytotoxicity (+).

As evident from Table 1, cyphenothrin showed the most favorable results.

Furthermore, the efficacy (pesticidal rate of honey bee mites), phytotoxicity and workability of the smoke smoke pest control agent of the present invention (referred to as the product of the present invention) using the above-mentioned cyphenothrin as an insecticidal component,
Commercial product I (smoke agent) selected as control product, commercial product II
(Smoke agent) and commercial product III (emulsion). The above-mentioned evaluation criteria were directly adopted for the medicinal effect and the phytotoxicity, and the workability was evaluated as a difficult two-stage evaluation.

As is clear from Table 2, the product of the present invention can control only pests without affecting beneficial organisms by adjusting the blending amount of cyphenothrin, and it is easy to use. It can be said that this is far superior to the conventional product.

〔effect〕

From the above, the smoke and insect pest control agent of the present invention does not damage the bee, which is a beneficial organism, and has the medicinal effect of controlling only the pest, honey bee mite,
It has become possible to control honeybee mites, which are parasitic on bees, in an extremely simple manner at the same time as ordinary smoke treatment. The control agent of the present invention has many advantages, such as leaving only a small amount of ash even after the practice of smoking, and having a very simple finishing work.
