Effect of imidacloprid soil treatments on occurrence of Formosan subterranean termites (Isoptera: Rhinotermitidae) in independent monitors.
Periodic sampling of 30 independent monitors, initially active with the Formosan subterranean termite, Coptotermes formosanus Shiraki, was conducted to evaluate the effects of soil treated with imidacloprid on nearby termite activity. Monitors were located adjacent (1-3 m) to the buildings. Soil around and under the buildings was treated with 0.05% imidacloprid. None of the termites collected showed latent mortality attributed to imidacloprid intoxication. Imidacloprid soil treatments did not measurably reduce C. formosanus populations adjacent to the treatments. Imidacloprid does not seem to fit the liquid-bait model.
