摘　　要：[目的]明确14%氟虫腈·嘧菌酯悬浮种衣剂对玉米二点委夜蛾的防治效果及用药量。[方法]采用药剂拌种法进行田间药效试验。[结果]14%氟虫腈·嘧菌酯FS有效成分使用剂量药种比为1∶750对玉米二点委夜蛾药后7 d的防效可达90.69%,与对照药剂50 g/L氟虫腈FS拌种处理差异显著。[结论]14%氟虫腈·嘧菌酯悬浮种衣剂能有效防治玉米二点委夜蛾,并对玉米的出苗率无不良影响。[Aims] The paper aims to verify the control effect and applied dosage of fipronil · azoxystrobin 14% FS on A thetis lepigone. [Methods] Field efficacy were determined with seed treatment method. [Results] The results of field trials showed that the 7 days after treatment of fipronil · azoxystrobin 14% FS were 90.69% at 1：750, and there was significant difference compared to the reference pesticide （fipronil 50 g/L FS）. [Conclusions] Fipronil ·azoxystrobin 14% FS was an ideal pesticide on controlling A. lepigone, and it was safe one maize seed.
