摘要
从内蒙古太仆寺旗自然死亡的柳毒蛾虫尸中分离提纯多角体．其平面图呈不规则形状，有三角形、四～六边形和近圆形．大小相差悬殊，直径在０．９４～２．４７μｍ之间．约有５６．４％的多角体在１．６０～２．１０μｍ之间，平均为１．７８μｍ．多角体硷解后释放出短杆状病毒束，大小为２０４～４１６ｎｍ×１０４～２９４ｎｍ之间，有４２％的病毒束在３４５～３６５ｎｍ×１６１～１８５ｎｍ之间，平均为３５８×１７０ｎｍ．约７４．１％的病毒束包埋４～７个病毒粒子．病毒粒子呈杆状．统计表明，约７２．８％的病毒粒子长度分布在３１０～３２０ｎｍ之间，平均大小为３１５×４９ｕｍ．测定不同龄期幼虫单体多角体产量的结果显示，５龄幼虫比４龄和３龄幼虫高得多．
The morphology of Leucoma salicis nuclear polyhedrosis virus isolated from NeiMonggol was studied. Results showed that the size of polyhedra of LSNPV-IM measured from 0. 94￣2. 47 μm in diamter and include in many virus size bundles which measured from 204￣416 um × 104￣294um, average size was 358 um × 170 um. Most virus bundles include 4 ￣ 7 virious. The size of LSNPV particles are 315 um × 49 um.
