文摘内容 The experiment on control of Lymantria dispar L by using different kinds of biological measures, including nuclear polyhedrosis virus (NPV) of Lymantria dispar L., BtMP-342, sex-attractant as well as botanical insecticide, was carried out in the forest regions of Inner Mongolia in 2003. Two concentrations (2.632×10^6 PIB·ml^-1 and 2.632×10^7 PIB·ml^-1) of Lymantria dispar L. NPV were sprayed on the 2rd-instar-larvae of L. dispar and 70% and 77.8% control effect were obtained respectively. BtMP0-342 was applied to the 3rd- and 4th-instar larvae and the control effect was around 80%. The sex-attractant provided by Canada Pacific Forestry Research Center also showed a good result in trapping L. dispar adults. The self-produced botanical insecticide, which was extracted from a kind of poisonous plant distributed in Daxing'an Mountains, China, exhibited a good control result in controlling the larvae of L. dispar, and 82% mortality was observed when spraying primary liquid of the botanical insecticide on the 3rd-5th-instar-larvae in lab。
