Abstract:

The results of the investigation on population dynamics of pod borer (Helicoverpa armigera Hubner) in relation to abiotic factors revealed that the pest commenced from 7th standard week, which remained till 18th standard week with its peak activity during 15th standard week. The correlation studies indicated highly significant positive association between larval population of H. armigera and mean maximum temperature (0.349**) and highly significant negative association between H. armigera and mean relative humidity (morning) (-0.284**). The non-significant effect was observed between larval population of H. armigera and mean relative humidity (evening) (-0.256) and mean rainfall (-0.174). Mean minimum temperature had significant effect on the H. armigera population (0.404).
