Abstract

The invention provides an insecticidal composition for controlling the sanitary insect pests such as mosquitoes, flies, blattella germanica, and the like. The insecticidal composition comprises a component (A) dichlor dimefluthrin and a component (B) 2, 3, 5, 6-tetrafluoro-4-methoxyl methyl benzyl-3-(3, 3, 3-trifluoro-propenyl)-2, 2-dimethyl propane carboxylate, wherein, the mass ratio between the component (A) and the component (B) is 1:20 to 99:1. The coil type mosquito repellent incenses, the electric mosquito-repellent mats, the electric mosquito repellent vaporizer, the insecticide aerosol and other products which are prepared by using the insecticidal composition have the advantages of rapid killing to the insect pests and long-term drug effect.

Description

technical field [0001] The invention relates to an insecticidal composition and its application in preventing and controlling mosquitoes, flies, german cockroaches and other hygienic pests. Background technique [0002] It is widely known that pyrethroids can be used to control mosquitoes and have high insecticidal activity. Because of its high efficiency, low toxicity, low residue and good environmental compatibility, it has been widely used in the field of sanitary pest control. But along with the growth of use time, mosquitoes and flies have produced certain resistance (Gao Xiwu etc., Chinese Journal of Vector Biology and Control, 2004, 15 (2), 105). [0003] The inventors have formed a series of novel fluorine-containing pyrethroid compounds by modifying the structure of traditional pyrethroid acids and alcohols. The risk of resistance is improved, and the drug efficacy test of the new compound shows that it has good insecticidal activity, which is several times or ev...
