摘　　要：为筛选防治甜菜夜蛾的高效药剂,以1%甲维盐乳油、10%虫螨腈悬浮剂(SC)为对照,比较了不同用量甲维盐·虫螨腈悬浮剂对甜菜夜蛾的防治效果。试验结果表明,21%甲维盐·虫螨腈SC3个处理(12、9、6g/667m^2)对甜菜夜蛾均具有良好的防治效果,药后3d防效最高,分别为95.10%、89.31%和84.16%,具有较好的速效性,持效期为10d以内,是防治甜菜夜蛾较为理想的药剂,建议与其他农药轮用。In order to screen out high-efficient insecticides for controlling Spodoptera exigua, the control efficacy of different dosages of 21% emamectin benzoate-chlorfenapyr suspension concentrate (SC) to S. exigua was compared, with 1% emamectin benzoate emulsifiable concentrate (EC) and 10% chlorfenapyr SC as the control treatments. The results showed that the 3 treatments of 21% emamectin benzoate-chlorfenapyr SC (the dosages were 12, 9 and 6 g/667 m^2) had better control effect to S. exigua. The best control effects were on 3 days after applying the insecticide, with the control efficiencies of 95.10%, 89.31% and 84.16%, respectively. Meanwhile, they had a quick-acting effect and the lasting period was within 10 days. Therefore, 21% emamectin benzoate-chlorfenapyr SC was an ideal agent to control S. exigua, and it should be rotated used with other insecticides.
