Abstract
Tarnished plant bugs (TPB), Lygus lineolaris Palisot de Beauvois, are serious pests of cotton in some years in the Mississippi Delta. They hibernate during the winter in dead weeds and surface woods trash and feed on a variety of early-emerging plants in the spring. Fleabane, Erigeron annuus (L.) Pers.. is the most important spring host. TPB migrate to cotton during its most susceptible stage of growth from mid-May through June and may cause some fruit loss throughout the summer. The sequential occurrence of the various wild weed hosts supports TPB populations until the hosts are killed by frost.
