How pea moth larvae causes damage in pea ?

The larvae hatch from the eggs laid on the leaves and blossoms, then they enter the developing pea pod to feed the seeds. Infested pods turn yellow and ripen too soon. In certain pods, more than one larva can be seen. In early sown pea crops, the infection of these larvae may be minimal. Spray malathion 50 EC @ 10 ml or Bouveria bassiana, a fungus-based biopesticide @ 40 g per 10 lit of water if the infestation is severe.
