摘　　要：在河南濮阳选用杀铃脲等4种不同浓度杀虫剂对杨白潜叶蛾幼虫进行了田间药剂防治对比试验,结果显示5%杀铃脲SC、10%吡虫啉WP和48%毒死蜱EC1000倍效果最好,喷药后11 d相对防效均为100%;其次为10%吡虫啉WP、1.8%阿维菌素EC、5%杀铃脲SC和48%毒死蜱EC 1500～2 000倍,相对防效在88%～98%。本着经济、有效、环保的原则,建议生产上在幼虫危害初期用5%杀铃脲SC 1 500～2 000倍树冠喷施或与其它3种杀虫剂2 000倍交替使用进行防治。The efficacy of different concentrations of 4 insecticides on larva of Leucoptera susinella was tested in the field in Puyang.The result showed that 1 000 time solutions of Triflumuron 5% SC,Imidacloprid 10% WP and chlorpyrifos 48% EC had excellent control effect on the larva which was 100% 11d after the spray.The control effects of 1 500-2 000 time solutions of Triflumuron 5% SC,Imidacloprid 10% WP,Abamectin 1.8% EC and chlorpyrifos 48% EC were the next,which were 88%-98% 11 d after the spray.It was suggested that 1 500-2 000 time solutions of Triflumuron 5% SC and 2 000 time solutions of the other 3 insecticides be used alternatively in the control of the larva.
