樟子松人工林松沫蝉药剂防治研究

Chemical Control of Aphrophora flavipes in Pinus sylvestris var.mongolica Plantation

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15mL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411-1 181头·株-1。

In Pinus sylvestris var.mongolica plantation in Zhanggutai Region in Liaoning Province,control experiments against Aphrophora flavipes were carried out.Result shows that while controlling Aphrophora flavipes by injection in the nymph stage,insecticidal rate can reach above 40% when the injection concentration is 30% methamidophos（greater than 15mL）.Killing rate of deltamethrin is optimal among four chemical control spray medicines while spraying chemicals（deltamethrin,cyfluthrin,abamectin emamectin benzoate）to control adult insects.The effect is significant by applying deltamethrin in aerial control;death rate of Aphrophora flavipes are 411-1 181 ·trees-1.
