Cotton Fleahopper: Evaluation of New Insecticides and Impact on Cotton Lint Production

Roy D. Parker, Lawrence L. Falconer, Stephen D. Livingston, and Sidney W. Hopkins


Loss of squares caused by cotton fleahopper often has a detrimental impact on production of cotton lint. Two field studies were conducted to evaluate insecticides for control of cotton fleahopper to determine longevity of control and impact on lint production. Insecticides significantly reduced fleahopper numbers in both experiments. In one experiment yield increase due to insecticide treatment averaged 203 lb lint/acre which provided economic benefit of $63.09/acre. No added benefit was gained in the second experiment where cotton plants compensated for early fruit loss with extended late season fruit set.
