Quantifying Tarnished Plant Bug, Lygus Lineolaris (Palisot De Beauvois), Resistance To Acephate In Louisiana, Josh T. Copes
LSU Master's Theses
The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is one of the most yield- limiting insect pests attacking cotton in the Mid-Southern region of the U.S. This pest is almost exclusively managed with chemical control strategies. The organophosphate insecticide, acephate, has been one of the most important insecticides recommended to control tarnished plant bugs. In recent years, reports of unsatisfactory acephate performance have become common and actual field rates have been increased to improve control. The objective of this study was to survey acephate susceptibility in Louisiana populations of tarnished plant bug using laboratory bioassays and evaluate acephate efficacy …
