[目的]测定和评价20%虫酰肼悬浮剂对甜菜夜蛾的防治效果和安全性,为其推广使用提供技术支持。[方法]采用叶面喷雾法施药并测定不同用量的20%虫酰肼SC和25g/L溴氰菊酯EC防治甜菜夜蛾的效果。[结果]20%虫酰肼悬浮剂对甜菜夜蛾有较好地控制效果,药后3和7d,20%虫酰肼各处理防治效果分别达81%和84%以上,高于25g/L溴氰菊酯EC处理的防治效果。[结论]20%虫酰肼SC用于防治甜菜夜蛾,效果好,持效期为7d以上,并且对环境污染少,对甘蓝安全,是防治蔬菜甜菜夜蛾的理想药剂。

[Objective] The study was aimed to determine and evaluate control effect and security of 20% tebufenozide SC against Spodoptera exigua HObner, which would provide technical support for its promotion and utilization. [ Method] By using foliar spray method, control effects of different concentration of 20% tebufenozide SC and 25 g/L deltamethrin EC against S. exigua were determined. [ Result] 20% tebufenozide SC had better control effects on S. exigua. After spraying for 3 and 7 d, control effects of 20% tebufenozide SC in each treatment could reach 81% and 84%, which was higher than 25 g/L delt...
