樟子松人工林松沫蝉药剂防治研究

摘要

In Pinus sylvestris var.mongolica plantation in Zhanggutai Region in Liaoning Province,control experi-ments against Aphrophoraflavipes were carried out.Result shows that while controlling Aphrophoraflavipes by injection in the nymph stage,insecticidal rate can reach above 40% when the injection concentration is 30%methamidophos (greater than 1 5 mL).Killing rate of deltamethrin is optimal among four chemical control spray medicines while spraying chemicals(deltamethrin,cyfluthrin,abamectin & emamectin benzoate)to control adult in-sects.The effect is significant by applying deltamethrin in aerial control;death rate of Aphrophoraflavipes are 411-1 1 8 1 trees -1 .%通过在辽宁章古台地区的樟子松人工林中开展药剂防治松沫蝉试验，结果表明：若虫期用注干方法防治松沫蝉时，当注射浓度为30%甲胺磷大于15 mL 时，杀虫率可达到40%以上；喷洒药剂防治松沫蝉成虫时，敌杀死、功夫、阿维素菌、甲维盐等4种药剂中敌杀死效果最好，将敌杀死应用于飞防中，效果明显，杀死松沫蝉达411~1181头株-1。
