Time trends in mortality for thiamethoxam and fipronil against Formosan subterranean termites and eastern subterranean termites (Isoptera: Rhinotermitidae)
Journal of Economic Entomology 98 (3), 911-915
Abstract: Time trends in mortality for the Formosan subterranean termite, Coptotermes formosanus Shiraki, and eastern subterranean termite, Reticulitermes flavipes (Kollar), were determined for thiamethoxam and fipronil. Filter paper treated with 50 ppm thiamethoxam led to >80% mortality in 2-4 d for R. flavipes, whereas 5 ppm thiamethoxam resulted in >80% mortality in 2-3 d for C. formosanus. Filter paper treated with 1 ppm fipronil resulted in >80% mortality in 5 d for R. flavipes and 9 d for C. formosanus, indicating that thiamethoxam is faster acting than fipronil. As concentration decreases for slow-acting termiticides, the time required for adverse effects to be fully expressed increases.
