Bombyx mori nucleopolyhedrovirus (BmNPV) was isolated from the silkworm hybrid DMMMSU 209 using the modified method of Kobayashi and Kawase (1981). Electron microscopic examination of the virus revealed single encapsulated rod-shaped nucleocapsids approximately 0.35 um in size. SDS-PAGE analysis of BmNPV showed a major polyhedral protein with an estimated molecular weight of 28.56 kDa. Pathoge ...
