三年来,我们对棉铃虫VHA-273病毒的研究,除了进行室内及大田试验外,还通过病虫的组织切片,连续切片及超薄切片,对病毒在寄主体内的发生和病理,作了些观察。从病虫的切片观察中,我们发现唯一能在胞核内看到多角体的组织,有脂肪体、表皮及气管基质。因此,初步可以认为棉铃虫病毒在寄主体内的发生发展过程,也是与其
In the past three years, our research on the cotton bollworm VHA-273 virus has not only carried out indoor and field experiments, but also made some observations on the occurrence and pathology of the virus in the host through tissue sections, serial sections and ultrathin sections of the pests and diseases Observed. From the observation of the pests and parasites, we found that the only polyhedron tissue that can be seen in the nucleus is fat body, epidermis and tracheal stroma. Therefore, the initial can be considered that the occurrence and development of cotton bollworm virus in the host, but also with its
