Abstract:
A field experiment was conducted during rabi season of 2014-2015 at the research farm of Sam Higginbottom Institute of Agriculture Technology and Science, Deemed-to-be-University, Allahabad to evaluate the comparative efficacy of certain bioagents and botanical insecticides against pod borer, Helicoverpa armigera (Hubner) on chickpea, Cicer arietinum (L.). The occurrence of pod borer commenced from 6^th standard week (February second week) with an average population of 0.26 larvae/plant The pod borer population increased and gradually reached its peak level of 6.32 larvae/plant at 13^th standard week (March last week) there after declined trend was observed as temperature increased. It was observed that the temperature between 25-35 °C favoured the multiplication of gram pod borer.
