摘　　要：[目的]研究3%高效氟氯氰菊酯.甲维盐乳油对小菜蛾(Plutella xylostella)的防治效果。[方法]将3%高效氟氯氰菊酯和甲胺基阿维菌素苯甲酸盐按照不同比例混配,研究其对小菜蛾的毒力。[结果]3%高效氟氯氰菊酯.甲维盐乳油以2.0∶1.0的比例混配,共毒系数分别为124.78,表现为增效,且其对小菜蛾幼虫的LC50值为17.21 mg/L,对小菜蛾幼虫具有较强的毒杀作用。[结论]2.01∶.0的3%高效氟氯氰菊酯.甲维盐乳油对小菜蛾具有较好的防治效果。[ Objective ] The research aimed to study the control efficiency of 3 % beta-cyfluthrin and emamectin benzoate EC on P. xylostella. [ Method] 3% beta-cyfiuthrin and emamectin benzoate were mixed by different proportion, and then studied their toxicity to P. xylostella. [ Resuit] The co-toxicity coefficient was 124.78 when the mixed proportion of 3% beta-cyfluthrin and emamectin benzoate was 2.0：1.0, showed synergy. And its LC50 value to P. xylostella larvae was 17.21 mg/L, showed strong toxic effect on P. xylostella larvae. [ Conclusion] The EC of 3% beta-cyfluthrin and emamectin benzoate 2.0：1.0 has good control efficiency on P. xylostella.
