摘要： 田间小区试验结果表明，5.1%甲氨阿维·虫酰肼可湿性粉剂对番茄和白菜地的甜菜夜蛾均有较好的防治效果。在番茄地甜菜夜蛾卵孵化期施药，850~2000倍液，药后3d的防效最高，达74.92%~94.96%，药后7d已有新的幼虫孵化，防效开始下降；在白菜地甜菜夜蛾不同虫龄混发期施药，药后5d的防效最高，为83.85%~95.52%。对菜青虫有很好的兼治作用，而且对番茄和白菜安全。可以作为防治甜菜夜蛾的有效药剂推广使用，推荐使用浓度为850~1200倍。

Abstract: The results of field plot trial indicated: 5.1% emamectin benzoate +tebufenozide WP provided a satisfaction control effect against Spdoptera exigua (Hübnet) in different vegetable fields. In tomato field, the control effect were 74.92%~94.96% in the third day with the dilution times of 850-2000 spraying in the period of egg hatching days, and it dropped in the seventh day. In Chinese cabbage field, it gave the best control effect in the fifth day, which reached 83.85%~95.52%. This product also provided a satisfaction control effect against Pieris rapae, and security to tested vegetable species. It can be used to control Spdoptera exigua (Hübnet) in the field with the dilution times of 850~1200.
