为筛选出防治绿盲蝽的有效药剂，指导田间施药，采用试管药膜法，测定了6种杀虫剂对绿盲蝽3龄若虫的室内毒力。结果表明：阿维菌素、氟氯氰菊酯、吡虫啉、啶虫脒、螺虫乙酯和高效氯氰菊酯对绿盲蝽3龄若虫的LC50值，药剂处理24 h后，分别为8．19、10．39、19．96、25．30、25．77、28．17 mg/L；药剂处理48 h后，分别为3．64、5．86、10．39、17．57、15．93、12．21 mg/L。可见，阿维菌素对绿盲蝽毒力最高，氟氯氰菊酯次之，吡虫啉、啶虫脒、高效氯氰菊酯和螺虫乙酯毒力较低。

In order to screen out effective insecticides and guide their application in field , the toxicity of six insecticides to 3-instar nymphs of Apolygus lucorum was determined by residual film method in laboratory . The results showed that after treated for 24 hours, the LC50 of abamectin, cyfluthrin, imidacloprid, acet-amiprid, spirotetramat and beta-cypermethrin on 3-instar nymphs of A.lucorum was 8.19, 10.39, 19.96, 25.30, 25.77, 28.17 mg/L, respectively, while that was 3.64, 5.86, 10.39, 17.57, 15.93, 12.21 mg/L after treated for 48 hours respectively .The toxicity of abamectin was the highest followed by cyfluthrin , while that of imidacloprid , acetamiprid , beta-cypermethrin and spirotetramat was lower .
