Description

[Technical Field]

[0001] The present invention relates to an indoor crawling insect control agent and an indoor crawling insect control method. [Background technology]

[0002] Conventionally, various compounds have been known as active ingredients in insecticides for controlling indoor crawling insects such as cockroaches. However, depending on the application method and application situation, there may be a need for indoor crawling insect control agents and methods that have superior control effects such as flushing effect, knockdown effect, or lethal effect. On the other hand, it is known that metofluthrin, profluthrin, and transfluthrin exhibit insecticidal activity (lethal activity) against flying insects such as mosquitoes and flies (for example, Patent Documents 1 and 2). [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Patent No. 3728967 [Patent Document 2] Patent No. 2647411 [Overview of the project] [Problems that the invention aims to solve]

[0004] The present invention aims to provide an indoor crawling insect control agent and an indoor crawling insect control method that have excellent control effects against indoor crawling insects, and in particular, excellent knockdown effects. [Means for solving the problem]

[0005] As a result of diligent research, the present inventors have found that a composition containing one or more substances selected from the group consisting of metofluthrin, transfluthrin, and profluthrin has an excellent control effect against indoor crawling insects, and is particularly excellent in knockdown and flushing effects, leading to the completion of the present invention.

[0006] In other words, the present invention relates to the following. (1) An indoor crawling insect control agent containing one or more active ingredients selected from the group consisting of metofluthrin, transfluthrin, and profluthrin. (2) An indoor crawling insect control agent containing metofluthrin and / or transfluthrin as active ingredients. (3) An indoor crawling insect control agent as described in (1) or (2), wherein control relies on a knockdown effect. (4) An indoor crawling insect control agent as described in (1) or (2), wherein control relies on lethal efficacy. (5) An indoor crawling insect control agent as described in (1) or (2), wherein control relies on a flushing effect. (6) The indoor crawling insect control agent according to any one of (1) to (5), wherein the indoor crawling insect is a cockroach and / or a bed bug. (7) The indoor crawling insect control agent according to any one of (1) to (6), wherein the indoor crawling insect is German cockroach, American cockroach, small American cockroach, Oriental cockroach, brown cockroach, brown-banded cockroach, Eastern cockroach, Japanese cockroach, or small-winged cockroach. (8) A method for controlling indoor crawling insects, comprising applying an indoor crawling insect control agent described in any one of (1) to (7) to an indoor crawling insect or to the habitat of an indoor crawling insect. [Effects of the Invention]

[0007] This invention makes it possible to control indoor crawling insects, specifically cockroaches and bed bugs by flushing, knocking down, or killing them. The control effect relies particularly heavily on the knockdown and flushing effects, and is especially useful in control situations involving spatial treatment. This is because imiprothrin, which is considered to have a high rapid effect against cockroaches and bed bugs, is not suitable for spatial treatment. [Brief explanation of the drawing]

[0008] [Figure 1]Figure 1 is a schematic diagram of the [spray dropping device] described in Test Example 1 and Test Example 6 of the present invention.

Mode for Carrying Out the Invention

[0009] Metofluthrin, transfluthrin, and profuthrin are known compounds and can be produced by the methods described in, for example, the specification of Patent No. 3728967 and the specification of Patent No. 2647411.

[0010] When optical isomers or geometric isomers based on asymmetric carbon exist in metofluthrin, transfluthrin, and profuthrin, each of them or any mixture can be used.

[0011] Examples of the indoor crawling pests against which the indoor crawling pest control agent of the present invention exhibits efficacy include the following. In the present invention, the control effect relying on the flushing effect, knockdown effect, or lethal effect is referred to as the control effect.

[0012] Such indoor crawling pests include cockroaches such as Blattella germanica, Blattella asahinai, Supella longipalpa, Blatta orientalis, Periplaneta americana, Periplaneta fuliginosa, Periplaneta japonica, Periplaneta brunnea, and Ectobius pallidus, booklice (Psocoptera) such as Liposcelis bostrychophila and Liposcelis entomophila, spiders such as Araneus ventricosus, Argyrodes miniaceus, and Clubiona japonicola, centipedes such as Scolopendra subspinipes and Scutigera coleoptrata, and mealworms such as Tenebrio molitor.

[0013] The indoor crawling pest control agent of the present invention can be used as various preparations. For example, heating evaporating agents such as incense, mat agents, and liquid evaporating agents, agents used in fan-type drug diffusers, oil agents, emulsion agents, aerosol agents, pump spray agents, wettable powders, flowable agents, microcapsule agents, powder agents, granule agents, tablet agents, fumigants, smoke agents, natural evaporating agents, sheet agents, and poisoned baits. The following means can be mentioned for making these preparations.

(2) A method of impregnating or coating a substrate with the active ingredient of the present invention in liquid form. (3) A method of mixing the active ingredients and a base material of the present invention and then molding them into a desired shape. Although there are differences depending on the formulation form, these formulations may contain one or more active ingredients selected from the group consisting of metofluthrin, transfluthrin, and profluthrin, preferably metofluthrin and / or transfluthrin, more preferably metofluthrin. Furthermore, the weight of the active ingredients should be 0.001 to 99% by weight, preferably 0.005 to 80% by weight.

[0014] Various carriers can be used when preparing the above-mentioned formulations. Examples of solid carriers include one or more types such as fine powders and granules of clays, talc, ceramics, and other inorganic minerals, felt, fibers, cloth, knitted fabrics, sheets, paper, yarn, foams, porous materials, and multifilaments.

[0015] Examples of liquid carriers include aromatic or aliphatic hydrocarbons (xylene, toluene, alkylnaphthalene, phenylxylethane, n-paraffin, isoparaffin, liquid paraffin, kerosene, diesel fuel, hexane, cyclohexane, etc.). Examples include halogenated hydrocarbons (chlorobenzene, dichloromethane, dichloroethane, trichloroethane, etc.), alcohols (methanol, ethanol, isopropyl alcohol, butanol, hexanol, benzyl alcohol, ethylene glycol, etc.), ethers (diethyl ether, ethylene glycol dimethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, tetrahydrofuran, dioxane, etc.), esters (ethyl acetate, butyl acetate, isopropyl myristate, hexyl laurate, etc.), ketones (acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, etc.), nitriles (acetonitrile, isobutyronitrile, etc.), sulfoxides (dimethyl sulfoxide, etc.), acid amides (N,N-dimethylformamide, N,N-dimethylacetamide, N-methyl-pyrrolidone, etc.), alkylidenes (propylene carbonate, etc.), vegetable oils (soybean oil, cottonseed oil, etc.), vegetable essential oils (orange oil, hyssop oil, lemon oil, etc.), and water. In the present invention, the indoor crawling insect control agent of the present invention, which contains metofluthrin as an active ingredient and uses a lower alcohol having 2 to 3 carbon atoms, such as ethanol or isopropyl alcohol, as a liquid carrier, is preferred in terms of control efficacy. Liquid formulations such as oils and aerosols of the indoor crawling insect control agent of the present invention, which contains metofluthrin as an active ingredient and uses a lower alcohol having 2 to 3 carbon atoms, such as ethanol or isopropyl alcohol, as a liquid carrier, are preferably used.

[0016] Examples of propellants used when forming an aerosol include one or more liquefied gases such as liquefied petroleum gas, dimethyl ether, and hydrofluorocarbon, and compressed gases such as compressed air, nitrogen gas, and carbon dioxide, with liquefied petroleum gas being preferred.

[0017] Examples of surfactants include one or more of alkyl sulfate salts, alkyl sulfonates, alkylaryl sulfonates, alkylaryl ethers, polyoxyethylene derivatives of alkylaryl ethers, polyethylene glycol ethers, polyhydric alcohol esters, and sugar alcohol derivatives.

[0018] Other formulation aids that can be used include stabilizers such as BHT (2,6-di-tert-butyl-4-methylphenol) and BHA (a mixture of 2-tert-butyl-4-methoxyphenol and 3-tert-butyl-4-methoxyphenol), colorants, fragrances, etc.

[0019] When the indoor crawling insect control agent of the present invention is made into an incense stick formulation, for example, a mixture of plant-based powders such as wood flour and tea powder, tabu powder, starch, and binders such as carboxymethylcellulose can be used as the base material for the incense stick.

[0020] When the indoor crawling insect control agent of the present invention is in the form of a mat formulation, for example, a base material made by solidifying cotton linters into a plate shape or a base material made by solidifying a mixture of cotton linters and pulp fibers into a plate shape can be used. When it is in the form of a hydrothermal fumigant, an organic foaming agent such as azodicarbonamide can be prepared as a base material, and a heating agent such as calcium oxide can be filled into a container. Furthermore, when using a base material such as a net as a natural vaporizing agent, for example, natural fibers such as pulp, cotton, wool, hemp, and silk, polypropylene, polyethylene, polyamide, polyethylene terephthalate, polybutylene terephthalate, polysulfone, rayon, and methacrylic acid resin can be used. When using a poisoned bait, for example, bait components such as grain flour, vegetable oil, sugar, and crystalline cellulose can be used as the base material, antioxidants such as BHT and BHA, preservatives such as dehydroacetic acid, ingestion prevention agents such as chili pepper powder, and insect attractants such as onion and peanut oil can be used.

[0021] The indoor crawling insect control agent of the present invention may be used in combination with various insecticides, acaricides, fungicides, repellents, and synergists as needed.

[0022] Examples of insecticides and acaricides include pyrethroid compounds such as terrarethrin, flamethrin, monfluorothrin, dimefluthrin, mepafluthrin, heptafluthrin, phenothrin, cyphenothrin, permethrin, cypermethrin, cyfluthrin, bifenthrin, fenpropatrin, deltamethrin, tralomethrin, etofenprox, imiprothrin, allethrin, phthalthrin, prallethrin, resmethrin, and natural pyrethrins; silicon compounds such as silafluofen; organophosphorus compounds such as dichlorvos and fenitrothion; carbamate compounds such as propoxur; neonicotinoid compounds such as dinotefuran, imidacloprid, and clothianidin; fipronil, indoxacarb, and methoxadiazone. Among these, the use of pyrethroid compounds is preferable, and the use of the non-volatile pyrethroid compounds phenothrin, cyphenothrin, permethrin, cypermethrin, cyfluthrin, bifenthrin, fenpropathrin, deltamethrin, tralomethrin, etofenprox, and resmethrin is more preferable. When such non-volatile pyrethroids are combined with one or more compounds selected from the group consisting of metofluthrin, transfluthrin, and profluthrin used in this invention, the excellent flushing, knockdown, and lethal effects of the latter compounds can synergistically enhance the control effect of the former pyrethroid. For example, the excellent flushing effects of metofluthrin, transfluthrin, and profluthrin drive indoor crawling insects out of their hiding places, increasing the opportunities for non-volatile pyrethroids to come into contact with the floor surface, thus providing a reliable control effect. This pest control effect is also advantageous because it prevents pests from accumulating in crevices after application, making the pesticide's effectiveness easily visible to the user.

[0023] Examples of disinfectants include isopropylmethylphenol, parahydroxybenzoic acid esters (ethyl, propyl, butyl), IPBC, thiobendazole, triclosan, and p-chlorometaxylenol (PCMX).

[0024] Examples of repellents include N-diethyl-m-toluamide, picaridin, IR3535, limonene, linalool, citronellal, menthol, menthone, hinokitiol, geraniol, and p-menthane-3,8-diol.

[0025] Examples of synergistic agents include piperonyl butoxide, cinepyrine 222, and cinepyrine 500.

[0026] The method for controlling indoor crawling insects of the present invention is carried out by applying the indoor crawling insect control agent of the present invention to indoor crawling insects or their habitats (bathrooms, storage rooms, living rooms, dining rooms, warehouses, furniture gaps, etc.). Alternatively, the method for controlling indoor crawling insects of the present invention can also be carried out by separately applying one or more active ingredients selected from the group consisting of metofluthrin, transfluthrin, and profluthrin, along with other active ingredients, to indoor crawling insects or their habitats. The method for controlling indoor crawling insects of the present invention can control indoor crawling insects by flushing, knocking them down, or killing them. Specific methods for applying the indoor crawling insect control agent of the present invention include, for example, the following methods, which can be appropriately selected depending on the form, location of use, etc. (1) A method of applying the indoor crawling insect control agent of the present invention directly to indoor crawling insects or to the habitat of indoor crawling insects. (2) A method of applying the indoor crawling insect control agent of the present invention to indoor crawling insects or to places where indoor crawling insects live, after diluting it with a solvent such as water. (3) A method of volatilizing the active ingredient of the indoor crawling insect control agent of the present invention by heating it at room temperature or in a place where indoor crawling insects live. In this case, the application rate and application concentration of one or more substances selected from the group consisting of metofluthrin, transfluthrin, and profuthrin can all be appropriately determined according to the form, application time, application location, application method, damage situation, etc. of the indoor crawling pest control agent of the present invention.

[0027] When using the indoor crawling pest control agent of the present invention, when applying it to space, the application rate is usually 0.0001 to 1000 mg / m as the amount of one or more substances selected from the group consisting of metofluthrin, transfluthrin, and profuthrin 3 , 3 , , 50 , 3 , 3 and when applying it to a flat surface, it is 0.0001 to 1000 mg / m 2 . When a flushing effect is desired, preferably 0.001 to 100 mg / m 3 , more preferably 0.01 to 50 mg / m 3 , even more preferably 0.05 to 10 mg / m 3 , most preferably 0.1 to 1 mg / m 3 can be applied. At that time, the B / A value calculated from the FT 50 value (B), which is the half expulsion time for the amount of treatment agent per unit treatment area (A), preferably shows an excellent flushing effect at a value of 0.1 to 50, more preferably 0.5 to 10, and even more preferably 1 to 3. Also, when a knockdown effect is desired, preferably 0.01 to 500 mg / m 3 , more preferably 0.1 to 200 mg / m 3 , even more preferably 1 to 100 mg / m 3 , most preferably 10 to 70 g / m 3 can be applied. At that time, the B / A value calculated from the KT 50 value (B) for the amount of treatment agent per unit treatment area (A) preferably shows an excellent knockdown effect at a value of 0.01 to 0.1, more preferably 0.01 to 0.05. The present invention's indoor crawling insect control agent is highly effective in control situations involving spatial treatment. This is because imiprothrin, which is considered highly effective against indoor crawling insects such as cockroaches and bed bugs, is not suitable for spatial treatment. Heat-dispersing agents such as incense sticks and mats are applied by volatilizing the active ingredient through heating, depending on the formulation. Non-heat-dispersing agents such as resin formulations, paper formulations, tablets, nonwoven fabric formulations, knitted fabric formulations, and sheet formulations can be used, for example, by leaving them as they are in the space to be treated, by spraying an aerosol agent into the space, or by blowing air onto the formulation. Examples of spaces to which the indoor crawling insect control agent of the present invention is applied include closets, storage rooms, chests of drawers, cupboards, toilets, bathrooms, storage rooms, living rooms, dining rooms, warehouses, car interiors, furniture, gaps between furniture, etc.

Five adult female German cockroaches were placed inside. 1 mL of a solution of various chemicals diluted to a predetermined concentration with acetone was sprayed at a rate of 1.5 kg / cm³ through a small hole in the center of the upper glass disc using an atomizer. 2 The process was carried out under pressure. The small hole at the top was plugged, and 10 seconds after processing, the sliding lid (not shown) of the partition that was installed at the joint between the cylinder and the glass pot was removed. The number of test insects driven out of the container by the flushing effect was observed for 10 minutes, and the FT (Focus Time) was determined as the half-expulsion time. 50 The values ​​were determined. The test was conducted under conditions of 25±2°C and 60±20% humidity.

[0057] The test results are shown in Table 4.

[0058] [Table 4]

[0059] The test results showed that metofluthrin and transfluthrin were highly effective, with metofluthrin in particular exhibiting a flushing effect in a very short time compared to other drugs, and its median flushing time (FT) was high. 50The value is within 1 minute and is the half-discharge time relative to the amount of treatment agent (A) per unit treatment area (FT). 50 The B / A ratio calculated for value (B) showed a significant value of 3 or less.
