Conservation of Baculovirus for the control of Bihar Hairy Caterpillar,Spilarctia obliqua (Walker) (Arctiidae: Lepidoptera)

摘要

The caterpillars of Spilarctia obliqua are susceptible to species specific virus, Spilarctia obliqua nuclear polyhedrosis virus (SoNPV). In this paper, methodology on mass production of SoNPV viral pesticide is discussed from the view point of field utility and conservation of the viral pathogen. This initiative is taken by virtue of eco-friendly approach of viral pesticide. The average yield of polyhedra of third & fourth instars is 3 X 108POBs and 7 X 109 POBs per dead larva respectively. The viability of the polyhedra was 24 months under the indoor conditions of Imphal.
