However, when n'≧2, k' represents the same or different groups. represents a group represented by ). ] This is a mixed insecticidal composition characterized by containing an ether derivative represented by the following.

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

Furthermore, it is a well-known fact that the ether derivative represented by the general formula (I) has insecticidal activity, as described in the specification of FR No. 8108642. The oxime ether derivatives used in this study have extremely low effectiveness in controlling adult insects, and also have the general formula (
The effect of the ether derivative shown in b) on larvae is not fully satisfactory. .

As a result of intensive research aimed at simultaneous control of larvae and adults, the present inventors discovered that by treating a mixture obtained by mixing pest control agents and insecticides with different activities,
We have found an insecticidal mixture composition that acts on larvae and adults of pests and can consequently reduce the density of reproductive adults.

The composition of the present invention includes planthoppers, leafhoppers, bodyflies,
Hemiptera such as aphids, stink bugs, and caterpillars; Isoptera such as termites; Hymenoptera such as ants and wasps; It is effective against pests such as Diptera such as Culex mosquito and house fly, Reciptera such as German cockroach, Coleoptera such as tobacco beetle and bean weevil, and Orthoptera.

Examples of the oxime ether derivative represented by the general formula tI) and the ether derivative represented by the general formula ([I) in the present invention include the following:
It goes without saying that the present invention is not limited by this. Incidentally, the oxime ether derivative includes optical isomers based on R2 and R, and geometric isomers based on R4 and R5, and it goes without saying that all of these are included in the present invention.

Table 1 Ether derivatives with the general formula (oxime ether derivatives Table 2 1) When the composition of the present invention is used as an insecticide, it is usually mixed with a solid carrier, a liquid carrier, a surfactant, and other formulation auxiliaries. and formulate emulsions, wettable powders, oils, powders, etc.

Each preparation can contain an oxime ether derivative and an ether derivative in a weight ratio of 01 to 99% as active ingredients, and the appropriate ratio of the oxime ether derivative to the ether derivative is 1:20 to 20:1. be.

These formulations can be prepared according to conventional methods. In this case, solid carriers include clays (e.g. kaolin, bentonite, acid earth, pyrophyllite, sericite), tuffs, other inorganic minerals (e.g. hydrated iron dioxide, pumice, diatomaceous earth, sulfur powder, activated carbon), etc. Powder or pulverulent materials can be mentioned.

[Carriers include alcohols (such as ethyl alcohol and ethyl alcohol), -ones (such as acetone and methylethylone), ethers (such as ethyl ethyl, dioxane, cellosolve, and tetrahydrofuran), aromatic hydrocarbons (such as ethyl ethyl, dioxane, cellosolve, and tetrahydrofuran), For example, benzene, toluene, xylene, methylnaphthalene), aliphatic hydrocarbons (
For example, ganlene, kerosene, kerosene), esters,

Formulation Example 2 Mix 5 parts of oxime ether derivative (29) and 10 parts of ether derivative (ill) with 51 parts of emulsifier (sodium lauryl sulfate), add 8.0 parts of 800 mesh diatomaceous earth, and stir thoroughly in a pickler. Mixing yields a hydrating agent.

Formulation Example 8 1 part of oxime ether derivative (5) and 1 part of ether derivative position) were dissolved in 20 parts of acetone, 98 parts of 800 Metsstarck were added, and after thorough stirring and mixing in a spreader,
A powder is obtained by removing the acetone by evaporation.

Formulation example 4 If the total 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,
Thoroughly mix 14 tons of wheat bran, 2 tons of powdered wheat, and 28 g of water, and place 4 house flies in the artificial medium for house flies.
Thirty day old larvae were released. Oxime etheric conductor (2

Similarly, a 20% emulsion of ether derivative (l/il) was prepared and diluted with water to a predetermined concentration.Meanwhile, a mixture was prepared by mixing each compound solution diluted with water to a predetermined concentration.This mixture Each single agent was sprayed for 20 hours each into a cage containing adult house flies and a container containing adult house flies.After spraying, the container containing house fly larvae was placed in an adult cage treated with the same agent, and from then on, adults in the cage were I investigated the numbers.

The result is the corrected density index as shown in the following equation. Results - The results are shown in Table 8.
