Control of Eastern Lubber Grasshopper on Florida Citrus

Florida Entomologist
Publication Date


Field tests were conducted from May to July 1967 at the Citrus Experiment Station, Lake Alfred, Florida to evaluate several insecticides against the eastern lubber grasshopper, Romalea microptera (Palisot de Beauvois). The insecticides tested for both initial and residual toxicity included organophosphate, carbamate, and chlorinated hydrocarbon compounds, many of which had been reported effective for the control of other grasshopper species. The most effective compounds 5 days after application were parathion, dieldrin, Mobam, Lannate, carbaryl, and phosphamidon. None of the materials were effective 12 days after application.
