摘　　要：五种常用杀蚧药剂的田间使用浓度对黑色软蚧蚜小蜂的成蜂和寄主体内的该蜂均有不同程度的影响。采用药膜法测定五种药剂对成蜂的毒性顺序为:喹硫磷>氧化乐果>水胺硫磷>速扑杀>机油乳剂。对寄主体内黑色软蚧蚜小蜂的影响大小依次为水胺硫磷>喹硫磷>氧化乐果>机油乳剂>速扑杀。Based on the results of the laboratory tests conducted, the contact toxicity of five common pesticides, including ometyoate 40EC, isocarbophos 40EC, quinalphos 25EC, methidathion 40EC, petroleum oil 95EC to the scale parasitoid Coccophahus yoshidae Nakayama abults was ranked as quinalphos > ometyoate > isocarbophos > methi-datyin>petroleum oil. Effect on the immature parasitoids inside the host mummies were determined as isocarbophos >quinalphos>ometyoatre>petroleum oil > methidathion. The adult emergence rate was 69.12% for the treatments with omethoate.
