Wireworms (Melanotus spp.) can be a problem of legumes and other vegetables by attacking seeds and seedlings. Wireworms are larvae of click beetles and can have extended life cycles that last 3 or more years. Common wireworms are hard, cylindrical, and brown; however, some wireworm species are softer with cream-colored bodies. Wireworms can reach a length of ½ to 1½ inches. Wireworms are frequently a problem in new fields following established sod.

Management:

• Seed treatments can reduce wireworm losses.
• Use wheat/corn bait traps in new fields prior to planting to estimate risk.
• Plant when soil temperatures are warm enough to promote rapid emergence and growth of seedlings.
• Soil-applied insecticides can reduce damage.
