Abstract
Twenty-five arthropod species, field-collected from habitats adjacent to cotton in Mississippi, were evaluated in laboratory arenas for their potential as late-season predators of the tarnished plant bug (TPB), Lygus lineolaris (Palisot). Seventeen species were demonstrated to be predators of the TPB, including 1 orthopteran, 6 hemipterans, and ten spider species. Five species were documented for the first time as predators on TPB: Jalyssus wickami Van Duzee (Heteroptera: Berytidae), Stiretrus anchorago (F.) (Heteroptera: Pentatomidae), Phymata pennsylvanica Hand. (Heteroptera: Phymatidae), Pisaurina mira (Walck.) (Araneae: Pisauridae), and Thiodina puerpera (Hentz) (Araneae: Salticidae).
