摘要
星天牛是黑杨的一种主要害虫。采用 7种农药对黑杨星天牛大龄幼虫进行虫孔注射防治试验。结果显示 ,4 0 %氧化乐果乳油 5 0 0～ 1 0 0 0倍液进行防治效果好 ,用药量每虫孔 5mL ,防治效果 96%～ 1 0 0 %。虫孔注药法是防治黑杨星天牛大龄若虫的有效方法。表 1参
Anoplophora chinensis is a primary borer pest damaged to Populus nigra.Chemical control was made at the larval stage by injecting into the worm channel in the trunk with 7 pesticides in different water solution.The results showed that 500～1 000 fold omethoate 40EC with 5 mL per worm channel could kill 96%～100% of the larvae.Injecting pesticite into worm grub is a good control way of Anoplophora chinensis.
