摘要
选取重庆市松墨天牛虫口密度相当的区域,采用监测点诱捕器诱捕天牛数量的方法,对比研究了直升飞机喷洒8%氯氰菊酯微囊悬浮剂和3%高效氯氰菊酯微囊悬浮剂防治松墨天牛成虫的效果。结果表明,触破式8%氯氰菊酯微囊悬浮剂防治松墨天牛效果优于缓释型3%氯氰菊酯微胶囊悬浮剂,飞防4次防治效果优于飞防3次,也只有飞防4次,这两种剂型的灭虫率才能达到70%以上,即有效控制松墨天牛飞机喷洒8%氯氰菊酯微囊悬浮剂4次防治天牛效果最好。
The experiment site was selected in area with moderate pest density in Chongqing.The Monochamus alternatus was trapped and counted.Two kinds of pesticides—8%cypermethrin millirod suspending agent and 3%efficient cypermethrin millirod suspending agent,was sprayed by helicopter respectively to compared the effect of the two pesticides.The result showed that touch-and-break style of 8%cypermethrin millirod suspension agent was superior to extended release of 3%efficient cypermethrin millirod suspending agent in control of Monochamus alternatus.Effect of spraying 4 times was better than that of 3 times.Both agents could reach control effect above 70%.
