Termite baits containing 0.10% chlorfluazuron mixed in alpha cellulose powder was evaluated against the Asian subterranean termite, Coptotermes gestroi Wasmann (formerly Coptotermes vastator Light) (Blattodea:Rhinotermitidae), in wood structures exclusively using above-ground bait (AG) stations. Wood structures with active infestations of C. gestroi were selected and baited from January to April 2016. Termite colonies from all test sites were successfully eliminated after 8-12 wk of baiting. All sites were further monitored for the next three consecutive months and no sign of either termite recovery or re-infestation of a different colony was detected. Successful elimination of C. gestroi infestation in structures using only AG stations indicated that in-ground bait stations (IGs) may not be necessary for successful termite baiting in the Philippines. Changes in termite baiting protocols in tropical countries are proposed to reduce the cost of baiting in the Philippines and other Southeast Asian countries.
