目前已知棉铃虫病毒病共有四种类型:核型多角体病毒病,质型多角体病毒病,颗粒体病毒病和虹彩病毒病(Martignoni＆lwai 1977;Stadelbacher et al.1978)。棉铃虫的质型多角体病毒(简称CPV)常与核型多角体病毒混合发生,给寄主的正常饲养繁殖和核型多角体病毒的增殖利用带来了重大困难。此外,对这类病毒在防治棉铃虫的作用方面也需要作出正确的评价。我们曾报道过棉铃虫质型病毒的分离、特征和病理学(苏德明等,1978),本文应用电子显微镜技术研究该病毒在寄主中肠上皮细胞内的形成过程,以进一步阐明其增殖发病机理,并为其利用研究提供依据。
There are currently four types of Helicoverpa armigera virus disease known: nucleopolyhedrovirus, protocornovirus, granulovirus and iridescent virus (Martignoni & lwai 1977; Stadelbacher et al. 1978). The polyhedrosis virus (CPV) of Helicoverpa armigera usually mixes with the nucleocapsid polyhedrosis virus, which brings great difficulties to the normal breeding and multiplication of the nuclear polyhedrosis virus. In addition, the correct evaluation of the role of such viruses in the control of cotton bollworms also needs to be made. We have previously reported the isolation, characterization and pathology of Helicoverpa armigera (Su Deming et al., 1978). In this paper, electron microscopy was used to study the formation of the virus in the host intestine epithelial cells to further elucidate its pathogenesis, And provide the basis for its research.
