The pickleworm, Diaphania nitidalis (Stoll) (Family Crambidae, previously Pyralidae), is found from Canada into parts of South America, and as far west as Oklahoma and Nebraska. It is an important pest of numerous cucurbits. Summer squash is the preferred host, but it also feeds on cantaloupe, cucumber, pumpkin and winter squash. Late-planted cantaloupes are heavily attacked in some areas.
