摘　　要：[目的]采用室内毒力测定和田间药效试验方法,测定6种药剂对萝卜蚜的敏感性。[结果]结果表明萝卜蚜对不同类型杀虫剂敏感性有较大差异,其中95%毒死蜱对萝卜蚜杀虫活性最高,LC50值为0.1215 mg/L,其次为94%阿维菌素,LC50值为0.7795 mg/L,95%高效氯氰菊酯的敏感性最低,LC50值为996.8046 mg/L。通过田间试验可知:10%吡虫啉可湿性粉剂、1.8%阿维菌素乳油、3%啶虫脒可湿性粉剂、1%甲氨基阿维菌素苯甲酸盐乳油、40%毒死蜱乳油和4.5%高效氯氰菊酯乳油对萝卜蚜的防效都非常好,3 d的防效均达98%以上,14 d的防效为100%。[结论]在测试的6中药剂中,目前田间萝卜蚜与桃蚜相比具有较低的抗药性水平。[Amis] The toxicities and field control efficacy of six insecticides to mustard aphid Lipaphis erysimi were studied. [Results] The results show that the mustard aphid has developed varied resistant level to different pesticides. Among the tested pesticides, chlorpyrifos has the highest toxicity with a LC50 of 0.1215 mg/L, then is the abamectin, with a LC50 of 0.7795 mg/L. The beta-cypermethrin has the lowest toxicity with a LC50 of 996.8046 mg/L. The field experiments show that the six pesticides tested, i.e. imidacloprid, abamectin, acetamiprid, emamectin benzoate, chlowyrifos and betacypermethrin, all have high control efficacy to the mustard aphid with at least 98% control efficacy in 3 days and 100% control efficacy in 14 days. [Conclusions] Compared with the green peach aphid Myzus persicae, mustard aphid presently has very low resistant level to the six pesticides tested in this study in field.
