Both the adults and nymphs feed on plant sap of plants in the cabbage family and can cause distortion of the head, or bud drop, on brussels sprouts. Though less common, these insects may also feed on potatoes, tomatoes, and okra.
Severe infestations can cause plants to wilt, turn brown and die. Often populations peak and fall quickly. The adult is a flat, shield-shaped stink bug about 3/8 of an inch long with red and black markings on its back. The nymph, though smaller and more round, has the same markings.
Cyfluthrin (Baythroid, Bayer Vegetable & Garden Insect Spray) can be used for control as it is labeled, effective and has a zero day waiting period between spraying and harvest. (Ward Upham)
