摘　　要：0．5％甲氨基阿维菌素苯甲酸盐微乳剂以药量10mL／667m^2防治甜菜夜蛾的效果明显优于其2倍使用剂量的乳油，药后3～7d，对苋菜上甜菜夜蛾的防治效果达到85％以上，显著优于1．8％阿维菌素乳油33．33mL／667m^2防治效果；施药量8．33mL／667m^2，药后7d，对丝瓜上美洲斑潜蝇的防治效果达85％以上，与1．8％阿维菌素乳油50mL／667m^2防治效果差异不显著。The effectiveness of 0. 5% emamectin benzoate microemulsion （ME） applied by 10 mL/667m^2 against Spodoptera exigua Hübner was significantly higher than that of 0. 5% emamectin benzoate EC by 2 times dose. it could achieve more than 85% effectiveness against SDodoptera exigua on Amaranthus tricolor 3 - 7 days after treatment by 10 mL/667m^2 , which was significantly higher than that of 1.8% avermectin EC applied by 33.33 mL/667 m^2. The effectiveness reached 89% 7d after treatment with 0. 5% emamectin benzpate ME by 8.33 mL/ 667m^2 a gainst Liriomyza sativae on Luffa cylindrica, which was not significantly different from that with 1.8% avermectin EC by 50mL/667m^2.
