Preventing and controlling wireworms

Wireworms are a common cotton pest which feed on germinating seeds and emerging seedlings. Two types of wireworms feed on cotton: true wireworms and false wireworms. True wireworms, commonly called click beetles, are members of the Elateridae family, while false wireworms, or darkling beetles, are from the Tenebrionidae family.

Overwintering larvae inflict the most damage as they become active in the spring. The larvae damage cotton by feeding on the root, hypocotyl (stem of the germinating seedling), and cotyledon (seed leaves) of plants before emerging from the soil. Root feeding can kill plants and reduce plant stand but usually results in stunting. Continue reading
