Morphogenesis of Vanessa urticae Nuclear Polyhedrosis Virus in Infected Fat Body Cells

We isolated a strain of Vu NPV. The present study primarily detailed some changes during the virus infection in larval fat body cells, five days after infection, cytopathological alteration appeared,and the virus has distinguished special structure and process of replication At early stage of infection, the nucleus enlarged and the nucleolus dispersed, the nucleus contained grannular matters resulting in a "cleared" area, and the virogenic stromate appeared. Near the virogenic stroma large amount of road nu...
