Abstract

Bacterial wilt is a devastating disease of cucurbit crops (melon, cucumber, squash, pumpkin) in Iowa. Striped and spotted cucumber beetles transmit the bacteria (Erwinia tracheiphila) to cucurbit plants when their infected frass comes in contact with feeding wounds and floral nectaries. Infected plants usually wilt and die within two weeks.
