Pest
Pea beetles (Bruchus pisorum, also known as pea weevil) are 5mm long brown to grey beetles that emerge from hibernation in spring.
Adult beetles feed on the leaves and flowers of plants. Female beetles lay single eggs on the outside of pea pods. Larvae then burrow into pea seeds to feed, emerging as adults around 40 days later.
Monitor crops during spring and use insecticide spray if adult beetles are found; dispose of infested seed.
