摘　　要：室内生测结果表明,ZJ2242对粘虫、小菜蛾和斜纹夜蛾等鳞翅目害虫表现出良好的杀虫活性,综合毒力LC50分别为2.08、59.89和16.84mg/L。毒作用方式测定表明,ZJ2242对粘虫胃毒作用明显(胃毒毒力LC50为5.03mg/L),而触杀作用很低。田间试验表明,ZJ2242对小菜蛾、斜纹夜蛾具有较好的防治作用,100～200mg/L处理7d的防效均在80%以上。In laboratory tests, ZJ 2242 showed fine bioactivities on Mythimna sepatara, Plutella xylostella. Prodenia litura. The LC50 values for comprehensive toxicity to these three insects were 2.08, 59.89 and 16.84 rag/L, respectively. The tests of mode of action showed that ZJ 2242 had highly oral toxicity, and had almost not contact toxicity. Field trials showed that ZJ 2242 had good control effects against Phttella xylostella and Prodenia litura. The efficacies of control were all above 80% seven days after application with the concentration of 100 to 200 mg/L.
