Thiamethoxam was examined in order to determine the lethal time to >90% mortality against the Formosan subterranean termite, Coptotermes formosanus Shiraki, and the eastern subterranean termite, Reticulitermes flavipes (Kollar). Filter paper treated with concentrations of 500 ppm and ³25 ppm thiamethoxam led to >90% mortality in 2-4 days for R. flavipes and C. formosanus, respectively, implying that thiamethoxam is a slow-acting compound for both species.

Keywords: thiamethoxam, lethal time
