Adults and nymphs pierce plant tissue with needle-like mouth parts and suck out plant juices from buds, blossoms, pods, stems, fruit, and seeds. Immature fruit and pods punctured by stink bugs become deformed as they develop, or drop off the plant. Seeds within pods turn brown and become flattened and shriveled, and fruit become unpalatable. Stink bugs damage bean plants and bean pods, green and red tomato fruit, okra pods, stems of melons, asparagus, peppers, corn kernels through the husks, and occasionally attack cabbage, eggplant, horseradish, mustard, pea and turnip. Most stink bug damage occurs in late summer or early fall.
