摘　　要：[目的]明确常用杀虫剂对金银花尺蠖的防治效果。[方法]选用5种药剂(敌敌畏、辛硫磷、溴氰菊酯、毒死蜱和高效氯氰菊酯)的原药和乳油分别对金银花尺蠖幼虫进行了室内毒力测定和田间药效试验。[结果]5种药剂中,高效氯氰菊酯的毒力最大,48 h的LC50为0.019 3μg/ml;其他依次为毒死蜱、敌敌畏、辛硫磷和溴氰菊酯,48 h的LC50分别为0.027 6、0.050 5、0.053 3和0.056 3μg/ml。5种药剂在药后7 d的防效均达到80%以上,其中4.5%高效氯氰菊酯乳油和48%毒死蜱乳油的效果最好,其药后7 d的防效均为100%。[结论]5种药剂对金银花尺蠖幼虫均具有较高的毒力和田间防效。[ Objective] The aim was to make sure the control effects of common insecticides on Heterolocha finyinhuaphaga Chu. [ Method] Tile toxicity in laboratory and control efficiency in the field of five insecticides （ chlorpyrifos, dichlmwos, phoxim, deltamethrin and bata-cyper- methfin） to H. finyinhuaphaga were tested. [ Result] In the five insecticides, the toxicity of bata-cypermethrin was the best, its LCso after 48 hours was 0. 019 3 μg/mi. The others were chiorpyrifos, dichlorvos, phoxim and deltamethrin, and their LCso after 48 h were 0. 027 6, 0. 050 5, 0. 053 3 and 0. 056 3 μg/ml, respectively. The control efficiency in the field of five insecticides all reached above 80% after seven days, among them the control efficiencies of 4.5% bata-cypermethrin EC and 48% chlorpyrifos EC were the best, and they both were 100%. [ Conclusion] The five insecticides had hizh toxicity and control efficiency in the field to H. iinyinhuaohaza.
