Abstract

PROBLEM TO BE SOLVED: To obtain an arachnid-controlling agent for domestic use, containing a specific compound showing high controlling effect and satisfying all of the following points: safety, persistency, convenience and the like. SOLUTION: This arachnid-controlling agent contains 2,4-dioxo-1-(2-propynyl) imidazolidine-3-imimethyl chrysanthemate (abbreviated to imiprothrin) as an active ingredient. This arachnid-controlling agent is preferably prepared in an aerosol. When this agent is prepared, imiprothrin usually is mixed together with a solid carrier, a liquid carrier, a surfactant and other auxiliary agents for preparation. This arachnid-controlling agent manifests high controlling effect against arachnids such as jumping spider, silk spider, 'OOHIMEGUMO', 'SHIMOFURIIOGUMO', and the like. When it is applied, for example, in order to repel spiders making their nests on the wall surface of a house, imiprothrin is used in an amount of >=0.01g/m<2> .

Description

Detailed Description of the Invention

[0001]

This invention relates to 2,4-dioxo-1
The present invention relates to a house spider control agent containing-(2-propynyl) imidazolidine-3-imimethyl chrysanthemate [hereinafter referred to as imiprothrin].

[0002]

2. Description of the Related Art About 1100 kinds of spiders are known in Japan. Several of them have been attracting attention as unpleasant pests, because they have been netted or wandered inside the house, and their shape and nest make the residents more uncomfortable than insects.
Pyrethroids widely used for controlling indoor pests such as mosquitoes and flies, such as allethrin and pralethrin, are less effective against spiders. Moreover, since spiders are taxonomically closer to mites than insects, application of phenothrin effective for indoor dust mites was tried, but this effect was not sufficient. For this reason, it has been considered that none of the highly safe drugs that can be used indoors has an active ingredient showing a special effect on spiders.

[0003]

SUMMARY OF THE INVENTION In view of the above situation, it is an object of the present invention to provide a house spider control agent which is satisfactory in terms of control efficacy, safety, sustainability, convenience and the like. To do.

[0004]

Means for Solving the Problems To solve the above problems, the inventors of the present invention have conducted diligent research, and as a result, by using imiprothrin, a revolutionary spider control agent for houses excellent in all respects. The present invention has been accomplished by finding that the above can be obtained. That is, the invention of claim 1 relates to a house spider control agent, which contains imiprothrin as a spider control component.

According to a second aspect of the present invention, in addition to the first aspect, the dosage form is an aerosol form.

[0006]

According to the constitution of claim 1, a very useful spider control agent for houses is provided. That is, a control agent containing imiprothrin as an active ingredient shows a particularly high control effect on spiders.

Imiprothrin, which is an insecticidal component of the present invention, is a known compound and is excellent in safety and stability under field conditions, and it includes Lepidoptera, Diptera, Netteres, Hymenoptera, etc. Practical application as a pest control agent is being promoted. On the other hand, the effect of imiprothrin on indoor dust mites is low, and therefore, not only the idea of a spider control agent but also the effect on spiders has not been reported at all. However, the present inventors, in view of the current situation that spider control agents that can be used indoors are eagerly awaited, as a result of conducting an efficacy test for spiders of imiprothrin having excellent fast-acting effect, it is shown that spiders are effective. I found it.

According to the second aspect of the invention, since the aerosol form is selected as the dosage form, a more convenient spider control agent for houses can be obtained.

In preparing the house spider control agent of the present invention, a solid carrier, a liquid carrier, a gaseous carrier, a surfactant, and other formulation auxiliary agents are usually used together with imiprothrin.

Examples of solid carriers include clays (kaolin, bentonite, etc.), talcs, silicas, alumina powder, activated carbons, plant powders, and the like, and liquid carriers include, for example, water and alcohols (ethyl alcohol). ,
Isopropyl alcohol, ethylene glycol, etc.), ketones (acetone, methyl ethyl ketone, cyclohexanone, etc.), ethers (ethyl ether, dioxane, etc.)
Cellosolves, etc.), aliphatic hydrocarbons (gasoline, kerosene, kerosene, etc.), aromatic hydrocarbons (benzene, toluene, xylene, methylnaphthalene, etc.), esters,
Solvents such as acid amides, nitriles and the like are suitable, and one or a mixture of two or more thereof may be used.
In addition, there are LPG (liquefied petroleum gas), dimethyl ether, chlorofluorocarbon, etc. as the gaseous carrier, and as the surfactant, alkyl sulfate ester salt, alkyl sulfonate,
Any commonly available substance such as polyoxyethylene alkyl ether, sorbitan fatty acid ester, and polyoxyethylene polyoxypropylene block polymer can be arbitrarily used. Furthermore, as the formulation auxiliary agent, a dispersant, a sticking agent, a stabilizer, etc. are appropriately used.

The house spider control agent of the present invention includes other insecticides as long as it does not inhibit the spider control effect of imiprothrin.
Bactericide, acaricide, repellent, synergist, antifungal agent, flavoring agent,
A multipurpose composition can also be obtained by blending a colorant and the like.

The thus-obtained house spider control agent of the present invention exhibits a high control effect on spiders such as the giant brown spider, the duck spider, the jumping spider, the reed spider, and the Japanese spider. The active ingredients contained in this drug and their compounding amounts are the dosage form, application target, application method,
It is appropriately determined according to the application place and the like. For example, 0.01g per 1 m ² for exterminating spiders that net on the walls of houses
The above imiprothrin is preferably applied.

[0013]

EXAMPLES The present invention will be further described below with reference to examples and test examples, but the present invention is not limited to the following examples as long as the gist thereof is not exceeded.

[0014]

Example 1 0.5 g of imiprothrin was dissolved in 30 ml of isopropyl myristate, and kerosene was added to bring the total amount to 1
After making 50 ml and filling the aerosol container, attach the valve part, and through the valve part, propellant (LPG) 15
0 ml was pressure-filled to obtain an aerosol (300 ml). About 2 ml of this aerosol agent was sprayed per 1 m ² in the house where the net-making or wandering of the spiders (Columbia spider, Simophryi spider, Jumping spider, Nephila spider, etc.) was observed. As a result, it was observed that the spiders jumped out immediately, and these individuals were knocked down in a few seconds to 60 seconds and then died.

[0015]

[Test Example 1] According to Example 1, various aerosols (300 ml) shown in Table 1 were prepared by changing active ingredients. One giant spider with a body length of 5 to 8 mm collected indoors was placed in a glass petri dish, and the test aerosol agent was sprayed for 1 second from a position 50 to 60 cm above the spider. Measure the time until the spider knocks down, K
The T ₅₀ value was determined and the efficacy of various aerosol agents against spiders was compared.

[0016]

[Table 1]

As a result of the test, the house spider control agent of the present invention containing imiprothrin showed a high rapid-acting effect on spiders. On the other hand, pyrethroids that are widely used with excellent insecticidal effect against mosquitoes and flies, such as phenothrin,
The potency of dl, d-T80-allethrin and d-T80-phthalthrin against spiders was low. Therefore, it was clarified that imiprothrin is useful as an active ingredient of a house spider control agent.

[0018]

EFFECTS OF THE INVENTION The house spider control agent of the present invention containing imiprothrin shows a high control effect against spiders such as the giant brown spider, the spider flies spider, the jumping spider, the acid spider, and the nephila spider that inhabit the interior of the house, especially in the form of an aerosol. Things are also very convenient.
