It is reported in JP-A-58-150559 that the oxime ether derivative represented by the general formula (I) has an excellent control effect on mosquito larvae, house fly larvae, etc. It is a fact.

However, the oxime ether derivatives represented by the general formula (Il) have extremely low effectiveness in controlling adult insects.On the other hand, the ether derivatives represented by the general formula (III) are those discovered by the present inventors. For sanitary pests,
It is useful as an agricultural insecticide (Japanese Unexamined Patent Publication No. 59-1
No. 08738) 0 As a result of intensive studies aimed at simultaneous control of larvae and adults, the inventors of the present invention have found that by treating pests with a mixture obtained by mixing pest control agents and insecticides with different activities, We have discovered an insecticidal mixture composition that can act on larvae and adults of the insects, resulting in a reduction in the density of reproductive adults.

The composition of the present invention has planthoppers, whiteflies,
Hemiptera such as aphids, stink bugs, and scale insects; Isoptera such as termites; Hymenoptera such as ants and Havana; Lepidoptera such as diamondback moths, stink bugs, and armyworms;
It is effective against pests of Diptera such as Culex mosquitoes and houseflies, Reciptera such as the German cockroach, Coleoptera such as tobacco beetles and red bean weevils, and Orthoptera.

Examples of the oxime ether derivative represented by the general formula (I) and the ether compound represented by the general formula (II) in the present invention include the following, but the present invention is not limited thereby. Needless to say, it is not. In addition, oxime ether derivatives include 几,
and a, and optical isomers based on R4 and
There are geometric isomers based on , but it goes without saying that all of these are included in the present invention.

Table 1 Oxime ether derivatives of general formula (I) When the composition of the present invention is used as an insecticide, usually
It is mixed with solid carriers, liquid carriers, surfactants, and other formulation auxiliaries to formulate emulsions, wettable powders, oils, powders, etc.

Each preparation can contain an oxime ether derivative and an ether compound as active ingredients in a weight ratio of 0.01 to 99%, and the mixing ratio of the oxime ether derivative and ether compound is 1:20. ~20:1 is suitable.

These formulations can be prepared according to conventional methods. In this case, clays (for example, kaolin,
Bentonite, acid clay, pyrophyllite, sericite), talc, and other inorganic minerals (eg, hydrated silicon dioxide, pumice, diatoms, sulfur powder, activated carbon), and other fine powders or powders.

Liquid carriers include alcohols (e.g. methyl alcohol, ethyl alcohol), ketones (e.g. acetone, methyl ethyl ketone), ethers (e.g. ethyl ether, dioxane, cellosolve, tetrahydrofuran), aromatic hydrocarbons (e.g. benzene, toluene, xylene, methylnaphthalene), IJl aliphatic hydrocarbons (e.g. gasoline, kerosene, kerosene), esters, nitriles, acid amides (e.g. methylformamide, dimethylacetamide), halogenated hydrocarbons (e.g. dichloroethane) , trichlorethylene, carbon tetrachloride), etc. Examples of surfactants include alkyl sulfates, alkyl sulfonates, alkylaryl sulfonates, polyethylene glycol ether m, and polyhydric alcohol esters. In addition, usable fixing agents and dispersants include casein, gelatin, starch/1. powder, CMG, gum arabic, alginic acid, lignin sulfonate, bentonite, molasses, polyvinyl alcohol, pine oil, agar, etc. Stabilizers include, for example, PAP (isopropyl phosphate), TCP (licresyl phosphate), Examples include tall oil, epoxy Kamiike, one surfactant each, and various fatty acids or esters thereof.

Next, some formulation examples and test examples will be shown, but the present invention is of course not limited to these.

,! ! ! Formulation Example 1 Oxime ether derivative (2) 10 parts, ether compound (I1) 10 parts, emulsifier (polyoxyethylene styrenated phenyl ether, polyoxyethylene styrenated phenyl ether polymer, alkylaryl sulfonate mixture) 20 1 part and 60 parts of xylene are added, and the mixture is thoroughly stirred and mixed to obtain an emulsion.

Formulation Example 2 5 parts of oxime ether derivative (29), 10 parts of ether compound (Vl), and 5 parts of emulsifier (sodium lauryl sulfate) were thoroughly mixed, 80 parts of 800 mesh diatomaceous earth was added, and the mixture was thoroughly stirred in a grinder. Mixing yields a hydrating agent.

Formulation Example 8 1 part of oxime ether derivative (5) and 1 part of ether compound (Xll) were dissolved in 20 parts of acetone.
After adding 98 parts of Metstalk and thoroughly stirring and mixing in a blister, the acetone is removed by evaporation to obtain a powder.

Formulation example 4 When the total amount is 100 parts, an oil solution is obtained.

Test Example 1 Fifty male and female adult house flies were placed in a cage. on the other hand,
14 g of wheat bran, 2 f of powdered feed, and 28 yxl of water were thoroughly mixed, and 100 4-day-old house fly larvae were released into the thus prepared artificial medium for house flies. 20% emulsion of oxime ether derivative (29) [oxime ether derivative (29)
9) Add 20 parts of an emulsifier (polyoxyethylene styrenated phenyl ether, -lyoxyethylene styrenated phenyl ether polymer and alkylaryl sulfonate mixture) and 60 parts of xylene to 20 parts, and stir and mix these thoroughly. I got it. ] was diluted with water to a predetermined concentration. Similarly, a 20% emulsion of ether compound (I) was prepared and diluted with water to a predetermined concentration. On the other hand, a mixture was prepared by mixing each compound solution diluted with water to a predetermined concentration.

This mixture and each single agent were sprayed at 20 ytl each into a cage containing adult house flies and a container containing house fly larvae. After spraying, the container containing the house fly larvae was placed in an adult cage treated with the same chemical, and the number of adults in the cage was then investigated. The results were calculated using the following formula as a corrected density index. The results are shown in Table 3.
