摘　　要：1.3%鱼藤.氰乳油和0.3%印楝素乳油对椰心叶甲的田间控制试验结果表明,1.3%鱼藤.氰乳油1000倍处理椰心叶甲各虫态7 d后,成虫、幼虫和蛹校正虫口减退率分别达到98.52%、100%和100%,0.3%印楝素乳油1000倍处理椰心叶甲各虫态7 d后,成虫、幼虫和蛹的校正虫口减退率分别为94.87%、94.65%和94.90%。说明2种生物制剂对椰心叶甲均具有较强的控制作用。Effects of two biological insecticides, 1.3% Rotenone-Fenvalerate emulsion, 0.3% Azadirachtin EC at three concentrations, 0.1%, 0.05% and 0.033% were studied in the field. The results showed that the two insecticides at concentration of 0.1% well controlled the adults, larvae and pupae of B.longissima. Seven days after Rotenone-Fenvalerate application, the corrected mortalities （CM） of adults, larvae and pupae were 98.52%, 100% and 100% respectively; After using Azadirachtin, the CMs of adults, larvae and pupae were 94.87%, 94.65%, 94.90% （concentration 0.1%）; These two insecticides had great control effects and should be applied to control B. longissima population in the field.
