舞毒蛾Lymantria dispar分布遍及我国大约18个省(区)、为害多种森林植物及果树,并且往往造成局部地区暴发成灾。1976年以来,在辽宁省、北京和河北省先后发现了舞毒蛾核型多角体病毒,并进行了大量的研究工作。1983年,我们又从新疆阿勒泰哈巴河林区的杨树上,采集到舞毒蛾的病死幼虫。在试验室内经捣碎、过滤、离心,得到的灰白色沉淀物,经过电镜观察,确定为舞毒蛾核型多角体病毒。多角体为不规则形,近乎球状,大小约在0.8—2.7微米,病毒粒子的大小约为380-396×84-88毫微米(见图) 1982年,美国科学考察队与我国合作,曾在北京、敦化、蛟河、镜泊湖、亚布力、孟家岗等地,采集到舞毒蛾核型多角体病毒,并与
Gypsy moth Lymantria dispar distributed throughout about 18 provinces (regions), the destruction of a variety of forest plants and fruit trees, and often lead to outbreaks of disasters in some areas. Since 1976, Liaoning Province, Beijing and Hebei Province has discovered a Gypsy moth nuclear polyhedrosis virus, and conducted a lot of research work. In 1983, we again collected the dead larvae of Gypsy moths from the poplar trees in the Habahe forest area, Altay, Xinjiang. After being crushed, filtered and centrifuged in the laboratory, the gray-white precipitate obtained was observed by electron microscope and identified as Gypsy moth nuclear polyhedrosis virus. Polyhedron is irregular, nearly spherical, the size of about 0.8-2.7 microns, the size of the virus particles is about 380-396 × 84-88 nm (see photo) 1982, the United States team of scientific expeditions and our country, in Beijing, Dunhua, Jiaohe, Jingpo Lake, Yabuli, Mengjiagang and other places, collected Gypsy moth nuclear polyhedrosis virus, and with
