摘　　要：选用2.5%高效氯氟氰菊酯和3%高效氯氰菊酯两种微囊悬浮剂农药,设计450 mL hm^(-2)和600 mL hm^(-2)两个用药量,利用背负式机动喷雾机对2m以下树干和地面进行15L hm^(-2)喷液量低容量喷雾试验,以灭杀越冬上树杨潜叶跳象成虫,结果表明:施药后30d,平均防效分别为87.7%、96.8%和91.5%、97.7%,均表现出良好的防治效果,但2.5%高效氯氟氰菊酯的用药成本相对要低,推荐使用。Two kinds of microcapsule suspending agent pesticide（2.5% efficient cyhalothrin ＆ 3% cypermethrin）were selected to design two doses（450mL hm-2 and 600 mL hm-2）.Spraying experiments with low-volume（15L hm-2 liquid spray）were conducted on the branches and ground below 2mby using knapsack motorized sprayer,so as to kill off the overwintering adult pests（Rhynchaenus empopulifolis）.Result shows that the average control effect after 30 days is 87.7%,96.8% and 91.5%,97.7%,respectively.They all show optimal control effect,but2.5% of the efficacy of cyhalothrin is relatively low and should be recommended.
