Abstract：The toxicity of seven common insecticides to female adults of Amblyseius swirskii was determined by slide-dipping method and comprehensive toxicity method,and the corresponding safety was evaluated.The toxicity of different insecticides to Amblyseius swirskii determined by slide-dipping method was as follows:Matrine>Valaxon>Chlorbenzuron>Abamectin>Fenpropathrin>Imidacloprid>Bt.The recommended concentration of Bacillus thuringiensis among the seven insecticides was safe for Amblyseius swirskii.Imidacloprid was low toxic to Amblyseius swirskii at the recommended concentration,and the low concentration of it had high security for Amblyseius swirskii.The comprehensive toxicity determination showed that matrine,phoxim,chlorbenzuron,abamectin and fenpropathrin were toxic to Amblyseius swirskii.The results showed that the five insecticides of phoxim,matrine,abamectin,fenpropathrin and chlorbenzuron were not recommended for the release of Amblyseius swirskii in the biological control park,and Bacillus thuringiensis and imidacloprid could be used in combination with Amblyseius swirskii when necessary.
