Comparative daily mortality (%) of three different HearNPV isolates against 2nd instar Helicoverpa armigera larvae in time response bioassays. The first virus induced mortality was observed on day 3 with the HearNPV-IND-K isolate and day 5 with the other two isolates. The virus induced mortality peaked on 7th day with the HearNPV-IND-K and HearNPV-IND-J isolates and 10th day with the HearNPV-IND-B isolate. After 10th day, no further virus induced mortality was observed with all isolates
