油松毛虫(Dendrolimus tabulaeformis Tsai et Liu)分布于我国河北、山西、陕西、山东、(泰山)、辽宁(阜新、朝阳、昭盟南部)。主要为害油松,是油松林的毁灭性食叶害虫。为了寻找一种“天然的”松毛虫防治剂,对松毛虫进行经济、有效的生物防治,我们在林地调查和室内观察、分析的基础上,于1977年9月在辽宁省建平县富山公社鱼山子林地的油松毛虫体内,发现并分离获得油松毛虫质型多角体病毒~[1]。最近作了组织切片和多角体及病毒粒子的电镜观察,现将结果报道于后。
Dendrolimus tabulaeformis Tsai et Liu distributes in Hebei, Shanxi, Shaanxi, Shandong, Taishan, Liaoning (Fuxin, Chaoyang and South of Zhao League) in China. The main damage to Pinus tabulaeformis, is a devastating leaf insect pests. In order to find a “natural” pinecone control agent, the pine caterpillars for economic and effective biological control, woodland in our investigation and indoor observation, analysis, based on September 1977 in Liaoning Province, Jianping County, Toyama commune Yushanzi Dendrolimi pine oil body, found and isolated from the oil-borne Dendrolimus polyhedrosis virus ~ [1]. Recently made of tissue sections and polyhedron and virus particles by electron microscopy, the results are reported later.
