摘要 小玳瑁蝴蝶（Aglais urticae）（鳞翅目：蛱蝶科）的幼虫经口感染核型多角体病毒。感染后每隔一定时间杀死并固定的幼虫切片通过光学和电子显微镜检查。在脂肪体细胞中观察到典型的病毒发育。然而，在受感染的中肠柱状细胞的细胞核中，尽管存在病毒颗粒和结晶多面体蛋白，但没有观察到病毒颗粒掺入多面体包涵体中。随后，在这些细胞的细胞核和基底膜之间的细胞质中发现了病毒颗粒。有人提出，这种不寻常的病毒发育在核多角体病毒的感染途径中具有重要意义。
Summary Larvae of the small tortoiseshell butterfly, Aglais urticae (Lepidoptera: Nymphalidae), were infected orally with a nuclear polyhedrosis virus. Sections of larvae which had been killed and fixed at intervals after infection were examined by light and electron microscopy. Typical virus development was observed in the fat body cells. However, in the nuclei of infected columnar cells of the mid-gut no incorporation of the virus particles into the polyhedral inclusion body was observed although both virus particles and crystalline polyhedron protein were present. Subsequently virus particles were found in the cytoplasm of these cells between the nucleus and the basal membrane. It is proposed that this unusual virus development is significant in the pathway of infection of a nuclear polyhedrosis virus.
