In Vitro Studies on the Virulence of Spodoptera Litura Baculovirus

Baculoviruses have been used as biopesticides against economic pests in agriculture, forestry and landscapes. In vitro production of baculoviruses has often been considered especially because of the ease of large-scale propagation. In this study, in vitro production was investigated by the infect...
