Hosts:

Tomato, (also squash, corn, beans, asparagus, okra, etc.)

Description:

The most common stinkbug is the green stinkbug. It is shield-shaped. When disturbed, it produces a stench foul enough to convince predators and people to leave it alone. It is most numerous where tall grass, weeds, and garden debris provide shelter for it during winter.

Symptoms:

Adults and nymphs pierce stalks, leaves, veins, or fruit, with their needle-like mouthparts and suck out plant juices. Plant may exhibit cloudy spots at puncture wounds. Young plants may wilt, turn brown, and die. Older plants will show stunting.

Control:

Remove and destroy garden debris each year in late fall. Keep weeds cut. Use floating row covers in home vegetable gardens to keep out stinkbugs. The tachinid fly parasitizes adult Southern green stinkbugs, while a tiny, parasitold wasp, parasitizes the eggs of that stinkbug as well as others. These two predators and the spined soldier beetle usually do a good job of controlling stinkbug populations. However, for major infestations, spray with insecticide.
