摘　　要：为筛选高效防治豇豆蓟马的药剂，研究了100 g/L 溴氰虫酰胺可分散油悬浮剂45 g a．i．/hm2、50 g a．i．/hm2、60 g a．i．/hm23种浓度的防治效果。结果表明：45～60 g a．i．/hm2剂量处理，药后1～10 d 的防治效果为34．57％～94．49％。其中，60 g a．i．/hm2剂量处理后1～3 d 的防效为50．60％～80．72％，5～10 d 防效为91．84％～94．49％；与对照药剂10％吡虫啉可湿性粉剂60 g a．i．/hm2处理相比，速效性略差，而持效性相当。试验期间未发现该药剂在供试剂量下对豇豆产生药害，可供生产中推广应用。To explore the high-efficient pesticide on controlling thrips on cowpea,the control effects of cyantraniliprole 100 g/L OD with 45 g a.i./hm2 ,50 g a.i./hm2 and 60 g a.i./hm2 on controlling thrips were determined via the method of field spray. The results showed that the control effects of cyantraniliprole 100 g/L OD with dosage of 45~60 g a.i./hm2 after 1~10 days were 34.57%~94.49%. The control effects of cyantraniliprole 100 g/L OD with dosage of 60 g a.i./hm2 after 1~3 days treatment were 50.60% ~ 80.72%,and 91.84% ~ 94.49% after 5 ~ 10 days,the persist control effects had no significant difference compared with imidacloprid 10% WP at 60 g a.i./hm2 ,but the imidacloprid 10% WP did have more rapid control effects. Meanwhile, there was no phytotoxicity at these doses, the cyantraniliprole 100 g/L OD can be applied and extended in cowpea field.
