摘　　要：采用纱笼法,分析3种农药(2.5%的溴氰菊酯乳油、40%的水胺硫磷乳油、阿维菌素)防治杨小舟蛾的效果,结果表明:3 000倍和4 000倍2.5%的溴氰菊酯乳油效果最好,在施药48 h后,幼虫死亡率达到了100%;其次为阿维菌素,施药72 h后幼虫死亡率达到了93.33%。从节约成本,保护环境的角度考虑,3种药剂的施用顺序是2.5%的溴氰菊酯乳油3 000倍液、4 000倍液,阿维菌素6 000倍液。The control effect of three kinds of pesticides（2.5% deltamethrin, 40% Isocarbophos EC, avermectin） on Micromelalo sieversi was analyzed with sarong method, the results showed that, 3 000 times and 4 000 times of 2.5% deltamethrin have the best effect, after spraying for 48 hours the larval mortality reached 100%; followed by abamectin, after spraying 72 hours the larval mortality reached 93.33%. From the view of cost saving, environment protecting, the spraying order of 3pesticides is 3 000 times, 4 000 times of 2.5% deltamethrin, 6 000 times of avermectin.
