Abstract
Mortality of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) was higher in the combined treatment of Nucleopolyhedrovirus (NPV) and Azadirachtin (AZA) and mortality was increased when AZA concentration was doubled. Larval mortality decreased as the age of the larvae increased in all the treatments. The time for 100% kill of third instar larvae was significantly reduced to 72 h when AZA (0.1 ppm) was combined with NPV (103 PIB/ml) when compared to 168 and 120 h for the same dose NPV and AZA individual treatments, respectively. The average leaf disc consumption, consumption index (CI), relative growth rate (RGR), the efficiency of conversion of ingested (ECI) and digested (ECD) food values were drastically reduced in the combined treatment of NPV and AZA than in the individual treatments. Larval as well as pupal durations were significantly extended and the adult longevity and fecundity were significantly reduced in the combined treatment of NPV and AZA. Weight of 14 day old control larvae was 420 mg and it was reduced to 299 and 248 mg after NPV (5 × 102 PIB/ml) and AZA (0.025 ppm) treatments, respectively. The larval weight was drastically decreased to 99 mg after the combined treatment at the same dose. The additive interaction between both the treatments, AZA and NPV, was found to be in a dose dependent manner and were highly compatible in disrupting the survival, feeding and biology of H. armigera.
