Plant Bugs on Fruit Trees
Tarnished plant bugs, Lygus lineolaris, other plant bugs, and various species of stink bugs feed on various tree fruits and on many wild and cultivated plants and make up a unique pest complex.
Description and life cycle
Tarnished plant bug adults are about 1/4 inch long, oval, fragile-looking insects, green to dark brown, flecked with white, yellow, reddish brown, and black markings. Nymphs are pale yellow to green. Stink bugs are broadly shield-shaped, flattened, with a narrow head and rather short legs, and are green to brown. All have the front half of the forewing leathery and the back half membranous. Mouthparts are the piercing-sucking type; the beak is three- or four-segmented, arises on the front of the head, and is held below the body, between the legs, when not in use. Antennae are usually long and four- or five-segmented. Compound eyes are normally large. Nymphs (immature stage) are generally similar to adults but do not have wings.
