The tarnished plant bug, Lygus lineolaris, is the primary pest of cotton in Mississippi. In recent years, producers have averaged up to approximately $75 per acre in foliar control costs for this pest. In 2010 a field study was conducted in Stoneville, MS to evaluate the impact of planting date and varietal maturity selection on tarnished plant bug population densities, yield, and reducing dependency on foliar insecticide control methods. Earlier planting dates and the early maturing variety provided higher yields while sustaining less yield loss due to tarnished plant bugs. The two earlier planting dates also required fewer foliar insecticide applications to maintain tarnished plant bugs below the economic threshold for MS.
