摘　　要：室内试验结果表明,90%万灵可溶性粉剂2500倍液、48%乐斯本乳油1500倍液对苹小卷叶蛾3龄幼虫的防效分别达到95.00%、88.33%;40%辛硫磷乳油1000倍液、0.2%保尔乳油1000倍液和20%灭幼脲悬浮剂1500倍液防效相对较差,均在60%以下。田间4种药剂的试验结果表明,48%乐斯本乳油1500倍液防效达到75.69%;90%万灵可湿性粉剂2500倍液达到68.92%。12%氯氰菊酯乳油2500倍液及20%甲氰菊酯乳油2500倍液的防效均不佳。The result of laboratory experiment indicates the control effects of 90% methomyl 2500 times and 48% chlopyrifox 1500 times against 3 instars larvae of Adoxophyes orana were 95% and 83. 33% , while the effects of 40% phoxim 1000 times and so on were less than 60%. The field test indicates that the control effect of 48% chlopyrifox 1500 times was 75. 69% and that of 90% methomyl 2000 times was 68. 92%. 12% cypermethrin and 20% fenpropathrin were not good pesticides to control Adoxophyes orana.
