Abstract

Thiamethoxam (ACTARA^® 25WG) was evaluated for its termiticidal properties against three species of economically important subterranean termites (Isoptera: Termitidae) in the Philippines: Nasutitermes luzonicus Oshima, Macrotermes gilvus Hagen, and Microcerotermes losbanosensis Oshima. Results of the study indicated that exposure to soil or ingestion of paper treated with thiamethoxam at concentration above 0.41 ppm may provide an adequate chemical barrier or induce high mortality against N. luzonicus, M. gilvus and M. losbanosensis after 5¨C9 days. Feeding bioassays showed that thiamethoxam was not repellent to M. gilvus and M. losbanosensis but had an anti-feeding effect on N. luzonicus.

Keywords: Thiamethoxam, Macrotermes gilvus, Nasutitermes luzonicus, Microcerotermes losbanosensis, Termitidae, subterranean termites
