| Abstract: | 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. |
