摘　　要：在扫描电镜下观察.家蚕质型病毒多角体大多数为8角六面体和12角八面体两种形状.三龄家蚕被质型多角体病毒感染9天后.病毒在中肠上皮细胞的胞质内完成病毒的装配,并形成病毒多角体.但在一些细胞核内发现块状多角体蛋白,这种多角体似乎不包含病毒粒子.主要细胞器的病理变化亦十分显著.Polyhedra of BmCPV were observed by scanning electron microscope. Most of them were octagonal hcxahcdra or dodccagonal octahcdra. Nine days after the third instar larvae were infected with BmCPV, the virus replicated and assembled to viral polyhcdra in midgut cptithium cells. But cubic polyhedral proteins in which seems not to contain any virons were observed in nuclei in some cells. Pathological changes were also obvious in some major organcllcs.
