摘　　要：叶蝉是稻田常见害虫,筛选出有效防治叶蝉的药剂,可以保障水稻安全生产,为农增产增收。试验结果表明,21%噻虫嗪悬浮剂对叶蝉具有很好的速杀性和药效持续性,150 g/hm2已达到对叶蝉的防治效果;30%吡蚜酮·仲丁威悬浮剂对叶蝉速杀性最差,但药效持续性强。Leafhopper is a common pest in rice fields. In order to improve the yield of rice, the effective pesticides were chosen to prevent and control leafhoppers in rice fields. The results showed that 21% thiamethoxam SC was good in the efficiency of quick-kill and persistence, 150 g/hm^2 of 21% thi-amethoxam SC had reached the control of leafhoppers. 30%pymetrozine· fenobu-carb SC was worse than 21% thi-amethoxam SC in the efficiency of quick-kill, but the efficiency of persistence was good.
