Experiments were conducted to evaluate the management of thrips (Thysanoptera: Thripidae) in peanut and cotton and the interaction between thrips and tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), in cotton. Although management of thrips with foliar insecticides historically has not been recommended in peanut, the current study observed significant yield benefits from the management of thrips with foliar insecticides. This was especially evident when peanut plants were stressed from herbicide injury. In another experiment, significant differences were observed among cotton varieties in terms of their susceptibility to thrips injury. Finally, an interaction between thrips injury and tarnished plant bug injury in cotton was not observed in these studies. However, both thrips and tarnished plant bug caused significant yield losses in cotton. Results from these experiments will be important for improving current integrated pest management programs in both cotton and peanut.
