摘　　要：采用浸虫法测定了4种药剂对苹果绵蚜的毒力以及复配药剂对苹果绵蚜的联合毒力。结果表明,供试杀虫剂对苹果绵蚜的毒力从大到小依次为啶虫脒>吡虫啉>联苯菊酯>高效氯氰菊酯;供试的啶虫脒和联苯菊酯系列复配剂对苹果绵蚜均有明显的增效或相加作用;不同复配剂中,以啶虫脒和联苯菊酯质量配比为1∶5时增效作用最明显,其余依次为啶虫脒与联苯菊酯2∶1,1∶1和1∶2及吡虫啉与高效氯氰菊酯1∶1和1∶5,其共毒系数均高于200。The toxicity of four pesticides to the woolly apple aphid, Eriosoma lanigerum Hausmann was studied by insect-soaking method in laboratory. The joint toxicity of mixtures was also tested. The results showed that the toxicity of four pesticides was ac- etamiprid 〉 imidacloprid 〉 bifenthrin 〉 beta-cypermethrin. The mixtures of acetamiprid and bifenthrin had the better synergistic effects on E. lanigerum. Among them, the effect of the mixture of acetamiprid and bifenthrin at the proportion of 1 ： 5 was the best, followed by acetamipfid and bifenthrin at the proportion of 2 ： 1, 1 ： 1 and 1 ： 2, imidacloprid and beta-cypennethriu at the proportion of 1 ： 1 and 1 ： 5, the co-toxicitv coefficient were hi^her than 200.
