Experiments were conducted to determine the impact of combining multiple best management practices to manage the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), on cotton. The implementation of this program reduced the amount of insecticide applications needed, significantly increased both square retention during the three weeks of squaring, and yield in the Delta region. Another study was conducted to explore behavioral responses of tarnished plant bug nymphs to several classes of insecticides. There appeared to be both avoidance and attraction depending on insecticide class. The presence of an insecticide did not affect the fruiting structure tarnished plant bugs were found on in the field, there were significantly more tarnished plant bugs found in the middle of the plant than the top or bottom at 3 DAT. At 7 DAT there were significantly more tarnished plant bugs found on the top of the plant followed by the middle then bottom.
