摘　　要：对１１种杀虫机制不同的杀虫剂防治抗药性小菜蛾进行田间药效试验结果表明，供试的５种菊酯类农药中氰戊菊酯的防效最差；两种有机磷农药防效差异不大，效果欠佳；两种生物制剂在试验中均表现出较好防效；４种农药与广效液的混合试验结果，混用防效均优于单剂．还根据试验结果及小菜蛾发生特点，提出了抗性治理对策。Field trials of 11 insecticide with various action mechanisms against resistant diamondback moth (Plutella xylostella) to pyrethroids was made. Among these insecticides, two bioinsecticides showed better efficacies than the two organophosphates. Under 5 tested pyrethroids, fenvalerate had the worst efficacy against P. xylostella. All insecticides could be synergized by adding with Guangxiaoye, a synergist. Based on the experiment results and the characteristics of P. xylostella, measurements for diamondback moth resistance management were suggested.
