The larvae hatch out from the eggs laid on the leaves and flowers enter into the developing pea pod and feed the developing seeds. Infested pods turn yellow and mature early. More than one larva may be seen in single pod. The infestation of these larvae may be less in early sown pea crop. In case of higher infestation, spray malathion 50 EC @ 10 ml or Bouveria bassiana, a fungus base biopesticide @ 40 g per 10 lit of water.
