In the present study, susceptibility of the silkworm, Bombyx mori to the pathogens of mulberry pest Glyphodes pyloalis was ascertained. Silkworm, Bombyx mori inoculated with the pathogens isolated from G. pyloalis (Microsporidian and Nuclear Polyhedral Virus) showed high mortality at larval and pupal stages. Silkworms inoculated with Microsporidian showed mortality of 53.66% at larval stage whereas silkworms inoculated with Nuclear Polyhedral Virus showed mortality of 61.00% at larval stage. The survival rate and pupation rate besides the other economical characters were also affected in the inoculated batches of silkworm. The v larvae inoculated with the pathogens of silkworm showed mortality of 90.64% and 92.00% due to Microsporidian and Nuclear Polyhedral Virus inoculation respectively. The study has revealed that G. pyloalis besides being a major pest of mulberry causing severe damage to the leaves also acts as alternate host for the pathogens causing diseases of silkworm. As such this pest needs to be managed to prevent loss to the mulberry plantations as well as spread of silkworm disease causing pathogens.
