| 摘 要： | 通过室内和田间小区药效试验对5种防治烟青虫的生物杀虫剂进行筛选，结果表明，供试生物杀虫剂防治效果都优于对照药剂2.5%高效氯氟氰菊酯乳油2000倍液，其中0.5%甲维盐微乳剂1500倍液对烟青虫的防效最好，施药后第3天的室内和田间防效均达到80%以上。施药后第7天，除16000 IU/mg Bt可湿性粉剂750倍液的室内防效为73.70%外，其他4种生物药剂的室内和田间防治效果均超过90%。

| Abstract: | Experiments on control of Helicoverpa assulta with 5 kinds of microbial insecticides were conducted.The results of laboratory and field tests indicated that control effects of five kinds of microbial insecticides were better than lambda- cyhalothrin at a dilution of 2000.0.5% emamectin benzoate microemulsion at a dilution of 1500 showed best,and control effects were over 80% in 3 days after application.Except to 16000 IU/mg Bt wp with 750 times dilution,which laboratory control effect was measured as 73.70%,control effects of other four microbial insecticides deal with laboratory and field were more than 90% in 7 days after application. |
