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%.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Chickpea; Cumulative effect; HaNPV; Helicoverpa armigera<\/em><\/strong><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t Bentham G., Hooker J.P. 1970.
