Epicauta spp.

Pest description and crop damage Adults are slender, oblong beetles with a relatively large head and an extenuated neck, often with yellow stripes in some form. Eggs are oblong and yellow. Larvae usually are found in several stages. All stages have three upper body legs. The pupa is a stage of darkening, starting with the eyes. The beetles get their name from a toxin they contain called cantharidin. Even dead insects can cause blisters if handled.

Management-cultural control

Weed control is important. Lambsquarters and wild mustard attract egg-laying females and provide a source of food for larvae. Fall tillage can help destroy overwintering pupae.

Includes

Bean aphid (Aphis fabae)
Green peach aphid (Myzus persicae)

Pest description and crop damage The bean aphid is dark olive green to black with light-color legs. It is usually more of an early-year pest. The green peach aphid is slender, dark green to yellow, and has no waxy bloom. Green peach aphid infestations may result in wilting.
