Abstract
AbstractWe evaluated the efficacy of fipronil baits in suppressing or eliminating field colonies of Microtermes mycophagus (Desneux) (Blattodea: Termitidae) an important subterranean termite pest in Pakistan. We tested two doses (10 and 30 ppm) of fipronil in toilet paper baits, chosen from laboratory repellency tests. We monitored four colonies for foraging activity for one month before baiting, and mapped foraging territories with termites marked with Nile Blue A and agonistic tests. Before the fipronil baits were installed there were averages of 782–1938 workers and soldiers per bait station in the four colonies. After baiting, the colonies were eliminated as there were no workers per bait station, whereas the control colony had an average of 1142 workers per bait station. The three possibly eliminated colonies consumed around 47 mg of fipronil formulation (4.7 mg active ingredient) in 45–90 days. Our results suggest that baits containing fipronil could provide an economical and feasible alternative for the management of M. mycophagus in structures and buildings in Pakistan.
