Interpretive Summary: Edible winter peas are a relatively new crop increasing in production in the Pacific Northwest. As a new crop advances in acreage, pest problems can develop that impact the production of the crop. The pea leaf weevil (Sitona lineatus) has developed as a major problem impacting winter pea production in the Pacific Northwest. Adult weevils can cause significant damage to pea foliage and larvae of the weevil prefer to feed on nitrogen-fixing nodules, resulting in reduced nitrogen to the plant, root disease issues due to feeding damage, and reduced nitrogen available to subsequent rotational crops. This articles helps to recognize this pest as causing major issues in the Pacific Northwest on winter peas and the need to utilize integrated pest management strategies to control it.
