摘要
应用电子显微镜技术观察了核多角体病毒在棉铃虫体内的增殖方式。在中肠细胞内增殖的核衣壳极少被囊膜包围 ,也很少形成多角体。它们能大量地释放到体腔 ,迅速感染其他敏感组织。在其他敏感组织内增殖的核衣壳大部分被囊膜包围形成病毒粒子 ,且随机包涵在多角体中形成核多角体。
The reproduction of Helicoverpa armigera nucleopolyhedrovirus in the midgut epithelia cells and the other sensitive tissues was observed by electron microscopy. The reproducing viruses in the midgut epithelia cells were mostly without envelopes, and thte polyhedrons were seldom formed. The reproduciing viruses in the other sensitive cells were with envelopes, and packed in polyhedrons.
