摘　　要：电镜观察结果表明，脂肪体细胞受八字地老虎核型多角体病毒感染后首先表现为细胞核膨大、染色质凝聚，随后细胞核内形成电子致密的病毒发生基质，在发生基质内及外周产生许多杆状的核衣壳，核衣壳在病毒发生基质与核膜间获得囊膜形成病毒束，病毒束从不同方向进入多角体蛋白，多角体形状趋于完善，最后充满整个细胞核．The TEM observation showed that the pathological changes after infection of fat hod-ies were enlargement or nuclei, dense aggregation of chromatin strands, formation of virogenic stroma, production of rodform nucleocapsids withinor around the virogenic stroma.The nucleocapsids were enveloped and formed virus bundles from the region between virogenic stroma and nuclear membrane. The virus bundles were occulded by polyhedra.
