摘　　要：[目的]筛选对玉米田禾蓟马[Frankliniella tenuicornis(Uzel)]具有较好防治效果的高效、低毒型药剂。[方法]研究了7种杀虫剂对玉米田禾蓟马的田间防治效果。[结果]7种杀虫剂对禾蓟马均具一定防治效果,其中乙基多杀菌素330 ml/hm2处理的防治效果最高,药后3、7、14 d分别达到84.30%、83.30%和82.34%。乙基多杀菌素、溴氰虫酰胺药后14 d防治效果均高于80%,且差异不显著。[结论]建议在禾蓟马初发期使用乙基多杀菌素、溴氰虫酰胺进行喷雾防治。[Objective] The aim was to screen efficient and low-toxicity insecticides which had good control effect on F.tenuicornis.[Method] Control effects of seven insecticides on F.tenuicornis in field were studied.[Result] The seven tested insecticides could kill the most of F.tenuicornis.The control efficiency of Spinetoram was the highest,and it reached 84.30% three days after treatment,83.30% seven days after treatment and 82.34% 14 days after treatment.The control efficiency of Spinetoram and Cyantraniliprole were both more than 80%,furthermore there was no significance between them.[Conclusion] In is suggested that Spinetoram and Cyantraniliprole could be sprayed at the incipient stage of F.tenuicornis to reduce them.
