通过４种药剂，多种浓度，２种施药方式对金钱松小卷蛾进行了防治试验。结果表明：喷雾效果优于打孔注药。喷雾最佳药剂为２．５％溴氰菊酯乳油，其２０００，４０００，８０００倍３种浓度防治效果均在９５％以上。打孔注药以５０％甲胺磷原液剂量８，１０ｍｌ效果较好，杀虫率可达８５％以上。
Two methods and four insecticides of various concentrations wereused in the test,The results showed that spray inginsecticides could producebetter results than injecting them,with solution of 2.5EC deltamethrin as thebest,It is testified that solutions with 2000,4 000,and 8 000 fold could con-trol over 95 percent of Olethrcutes sp.
