Abstract

To study the effects of induced tolerance in silkworm Bombyx mori L. against nuclear polyhedrosis virus two mulberry silkworm breeds viz., Pure Mysore and NB4D2 were selected. The breed susceptibility was determined during fifth instar. The silkworms were fed with known amount of inactivated nuclear polyhedral inclusion bodies (NPIBs) thrice at various time intervals for induction of tolerance followed by the challenge inoculation with known amount of live NPIBs. The silkworm larvae of the control, induced, induced followed by live PIBs inoculated and live NPIBs inoculated batches were allowed to continue development. The breed susceptibility, effect of polyhedrosis as well as induced tolerance on economic traits and their inheritance were studied. The induced and induced followed by live NPIBs inoculated batches exhibited almost similar pattern as in case of control larvae. This result paves light towards development of a practical control measure to be applied during mass rearing against the dreaded nuclear polyhedrosis in silkworm Bombyx mori L.
