Abstract

The instar-wise larval mortality in H. armigera due to HaNPV @ 0.500 ml/l showed a consistent decrease in all the five instars and cent per cent larval mortality was recorded in the first instar larvae. Early instar larvae were found to be the most susceptible as compared to later instar larvae. The cumulative (Larval + Pupal) mortality in all the instars ranged from 56.66 to 100.00% with an average of 78.66%.
