摘要
用电子显微镜观察了亚洲小车蝗痘病毒的形态，超微结构及在寄主体内的形态发生过程。该病毒的病毒粒子椭圆形，表面呈现桑椹状结构；侧体为圆筒形，髓核内绳索状结构有２折，在横切面上表现为２个圆点。包涵体之间能形成“嵌合体”。病毒粒子在寄主脂肪体中形成，其形态发生过程可分为４个主要阶段；病毒发生基质的出现、非成熟病毒粒子的形成、侧体的分化。
The morphological characteristics , the ultrastructure and the morphogenesis of Oedaleus asiaticus entomopoxvirus were examined with electron microscope. The virions of this virus were oval and looked like mulberry. The lateral body was cylinder-shaped. The ropelike structure in the core folded back only one time , therefore two spots in the transverse section could be seen . The occlusion bodies existed sometime in the form of “chimera” . The virions were developed in fat body cells, and their process of morphogenesis could be divided into four stages: the appearance of the viroplasm , the formation of the immature virions , the differentiation of the lateral body and the further evolution of the core and the capsid.
