摘　　要：采用盆栽法,测定8%辛硫磷微乳剂不同浓度对蚜虫和斜纹夜蛾药后1~3 d虫口减退率和防治效果。结果表明,8%辛硫磷微乳剂375 g ai./hm2处理对蚜虫防效显著优于对照药剂40%辛硫磷乳油375 g ai./hm2处理,93.75~187.5 gai./hm2处理与对照药剂40%辛硫磷乳油375 g ai./hm2处理无显著差异;8%辛硫磷微乳剂400 g ai./hm2处理对斜纹夜蛾防效与对照药剂40%辛硫磷乳油400 g ai./hm2处理相当。8%辛硫磷微乳剂对蚜虫和斜纹夜蛾具有良好的防治效果,可用于防治十字花科蔬菜蚜虫和斜纹夜蛾。The faded rate of the population and the efficacy of phoxim 8% ME at different concentration 1-3 day after sprayed pesticide against aphid and Prodenia litura were investigated using whole-plant bioassay.The results showed that the efficacy of Phoxim 8% ME at 375 g ai./hm2against aphid was obviously better higher than that of phoxim 40% EC at 375 g ai/hm2,and the efficacy of Phoxim 8% ME at 93.75-187.5 g ai./hm2was equal to that of phoxim 40% EC at 375 g ai/hm2.The efficacy of Phoxim 8% ME at 400 g ai./hm2 against Prodenia litura was equal to that of phoxim 40% EC at 400 g ai/hm2.Phoxim 8% ME had better efficacy against aphid and Prodenia litura,was applicable against aphid and Prodenia litura in the cruciferae vegetables.
