Test targets: culex pipiens pallens, female adults who do not take blood 3 to 5 days after eclosion;

the test method comprises the following steps: referring to GB/T13917.10-2009, simulating the scene;

and (3) test treatment: preparation examples 13 and 14, the total concentration of the active ingredients is diluted to 200 mg/l;

spraying equipment: longrui 616A for a small backpack sprayer;

table 4 formulation examples 13 and 14 efficacy comparison data

Formulation example 13 and formulation example 14 are both 3% acetamiprid + 0.5% d-trans-chlorpropenthrin emulsifiable concentrate, wherein 2-methyl glutaric acid dimethyl ester is added in formulation example 13, and formulation example 14 is not added, as can be seen from table 4, the efficacy of formulation example 13 is obviously better than that of formulation example 14, the diameter of the fog drop sprayed out from formulation example 13 is about 30 μm, and the diameter of the fog drop of formulation example 14 is about 55 μm, because the larger the diameter of the fog drop is, the smaller the number of dispersible granules of the liquid medicine in the air is, and the sedimentation speed of the liquid medicine granules is high, the suspension time in the air is short, and the poor efficacy is caused.

In conclusion, the acetamiprid-pyrethroid-containing sanitary insecticidal composition disclosed by the invention has an obvious synergistic effect on sanitary pests after the acetamiprid and the pyrethroid are compounded, and the slow-release agent for spatial spraying is added, so that the size of liquid drops in spatial spraying is reduced, the liquid drops are allowed to stay in space for a longer time, sanitary pests are killed more thoroughly, the pesticide application period is prolonged, the pesticide application frequency is reduced, and the labor cost is reduced.

The above examples are only for illustrating the technical concept and features of the present invention, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
