摘　　要：明确7种杀虫剂对斯氏钝绥螨Amblyseius swirskii的安全性,为协调化学防治与生物防治提供参考。本试验采用玻片浸渍法和综合毒性法测定了7种常用杀虫剂对斯氏钝绥螨雌成螨的毒力,并作出相应安全性评价。结果表明,玻片浸渍法测定的不同杀虫剂对斯氏钝绥螨的毒力大小依次为:苦参碱Matrine>辛硫磷Valaxon>灭幼脲Chlorbenzuron>阿维菌素Abamectin>甲氰菊酯Fenpropathrin>吡虫啉Imidacloprid>苏云金杆菌Bt。7种杀虫剂中苏云金杆菌推荐使用浓度对斯氏钝绥螨安全性高,吡虫啉在推荐使用浓度对斯氏钝绥螨低毒,低浓度对斯氏钝绥螨安全性较高;综合毒性测定表明,苦参碱、辛硫磷、灭幼脲、阿维菌素和甲氰菊酯对斯氏钝绥螨中毒。研究显示释放斯氏钝绥螨生防园建议不使用辛硫磷、苦参碱、阿维菌素、甲氰菊酯和灭幼脲这5种杀虫剂,必要时可以选择苏云金杆菌和吡虫啉与斯氏钝绥螨协同使用。The toxicity of seven common insecticides to female adults of Amblyseius swirskii was determined by slidedipping 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.
