摘　　要：[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 deltamethdn EC treatment. [ Conclusion] 20% tebufenozide SC for controlling S. exigua had good effect, which had permanent effectiveness for over 7 d. It also caused less environmental pollution, and was safe to cabbage, being the ideal pesticide for controlling S. exigua in vegetables.[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.
