摘要
马尾松毛虫(Dendrolimus punctatus walker)是我国南方松林的主要害虫。1974年,在广州市郊龙洞地区采集到马尾松毛虫质型多角体病毒(DPCPV),多角体呈六边形的廿面体,大小为0.5至6微米。病毒粒子廿面体,直径为42—56毫微米。经过十年的研究证实,DPCPV致病力高,对3—4龄幼虫的LC_(50)为2.5×10~5PIB/ml;林间防治试验四万余亩,平均杀虫率达70%以上;持效控制作用达5—6年;应用技术简便,可用松毛虫幼虫生产病毒,成本低;对脊椎动物无病原性及致畸作用。为防治马尾松毛虫提供了一种有效的生物防治手段。

Abstract
The Masson-pine caterpillar is the most serious pest of pinus spp. in southern China. we obtained a CPV of the masson-pine caterpillar (DCPV)in the Guang-zhou district in 1974. The polyhedra of DCPV are hexagonal in shape but vary in size from 0.5 to 6 μm in diameter. The virus particles are hexagonal in shape and range from 42 to 56 nm in diameter, we have been engaged in this research for ten years. The high infeciivity of DCPV has been shown: the Lc50 is 2.5 million polyhedra/ml for third to fourth insta...
