Abstract:

By the method of leaf immersion，the toxicity of four insecticides to Yponomeuta evonymellus of Euonymus fertunei was tested in the laboratory,in order to screening effective drug of high efficiency,low toxicity of pest prevention and cure.The results showed that four insecticides had toxic activity to Y.evonymellus.The susceptibility of Y.evonymellus to these insecticides was ranked from high to low as following：avermectin>chloraniliprole>chlorpyrifo>azadirachtin，the LC50 of them after 24 h and 48 h treatment were 1.96,7.18,12.53,276.46 mg/L and 1.19,1.03,6.30,184.40 mg/L respectively. As a conclusion，we recommended avermectin and chloraniliprole as alterative chemicals to control this insect pest.
