Sitona lineatus

Return to listing

Pea and bean weevil is a grey brown weevil with characteristic snout. It feeds on leaves, producing u shaped notches but it is its larvae that produce most of the yield reductions in beans. Eggs are laid on the soil and the larvae hatch, burying into the soil to feed on the roots. Pea and bean weevil can dramatically reduce root nodule formation and thus nitrogen fixation. The adult weevils overwinter in peas and beans, either in storage or in spilt crop around the field. They become active in March and will cause considerable damage to young seedlings.
