摘要
杨扇舟蛾是近年危害洞庭湖区杨树主要的食叶害虫之一,一年发生6～7代。本文采用生物药剂"林得保"(主要成分苏云金杆菌)粉剂防治杨扇舟蛾。试验表明:"林得保"粉剂在施药3 d后,开始显现明显的药理效果,最终防治率达到了95%以上,是一种在杨树食叶害虫防治上值得推广的无公害生物药剂。其喷粉浓度以药剂∶填充剂=1∶20的效果最佳。
Clostera anachoreta is an important leaf-biting pest of poplar in Dongting Lake area.It reproduces 6~7 generations per year.The experiment on control C.anachoreta using Lindebao powder（main component of Bacillus thuringiensis） is carried out.The results show that,3 days after applying this powder,it begins to appear obvious pharmacological effects.Eventually the control rate of C.anachoreta reaches 95% or more.So,the Lindebao powder is a pollution-free pesticide worthy of spreading for control leaf-biting pest of poplar.The optimum concentration is 1：20.
