Efficacy of experimental and commercial baits and surface residual treatments were compared using a novel "arboreal bioassay" field experiment for monitoring foraging populations of white-footed ants (Technomyrmex difficilis) nesting in and confined to coconut palms (Coco nucifera). Results were obtained from counts of ants foraging on the wicks of feeding vials. At 23 days after exposure (DAE) to treatments only the mean numbers of ants on wicks for 600 ppm bifenthrin surface treatment and NecDew proprietary matrix with 100 ppm thiamethoxam were significantly less than a 40% aqueous sucrose control. At 50 DAE, only counts of ants on wicks with NecDew with 100 ppm thiamethoxam were significantly less than the sucrose bait. Other products tested included 600 ppm fipronil surface treatment and 50 ppm imidacloprid liquid ant bait.
