ABSTRACT

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), has traditionally been considered an early season pest in Southeast Arkansas but has become more of a mid-to-late season pest as well. The expanded prominence of this pest necessi-tates continued applied research in the form of insecticide efficacy trials concerning its control. Our tests addressed the effec-tiveness of several new compounds when compared with existing compounds. Newer formulated compounds such as imida-cloprid (Trimax) and thiamethoxam (Centric) provided control of tarnished plant bugs comparable with that provided by older compounds such as acephate (Orthene), dicrotophos (Bidrin), and oxamyl (Vydate) and offer alternatives to aging and increasingly regulated insecticides.
