利用赤松毛虫质型多角体病毒(DsCPV)防治赤松毛虫和马尾松毛虫曾取得很好效果,为了探索扩大此种病毒的应用范围,寻找繁殖病毒的替代寄主,我们进行了赤松毛虫CPV感染某些鳞翅目昆虫的试验。 供试昆虫系室外诱捕成虫,室内产卵孵化饲养,于幼虫2龄时接种。供试病毒为中国林科院林研所提供,浓度为1×10~8多角体/毫升。将多角体悬液浸湿饲料,晾干后饲喂,2天 The use of DsCPV to control Cedilandelas and Dendrolimus punctatus has achieved good results. In order to explore the application range of this virus and search for alternative hosts for the replication of the virus, we conducted some studies on the infection of Cv. Dendrolimi CPV Lepidoptera insect test. The test insects were trapped in adults outdoor, ovipositing indoor incubation, larvae inoculated when the second instar. The test virus provided by Lin Institute of Chinese Academy of Forestry at a concentration of 1 × 10-8 polyhedron / ml. The polyhedron suspension wet feed, dry feeding, 2 days
