Résumé / Abstract

Field performance of a 0.5% methoprene-based granular bait (Protect-B) was evaluated against foraging Pharaoh ants, Monomorium pharaonis (L.) in pantries of dormitories of a university campus. A 1% hydramethylnon containerized bait (bait station) was used for comparison. Results indicated that both bait formulations provided more than 85% reduction in ant counts within 4 weeks post-treatment, and all baited populations were possibly eliminated within 8 weeks post-treatment. Subsequently, no Pharaoh ant was detected up to 12 weeks post-treatment. Upon reduction of Pharaoh ants, ant counts on index cards for several peridomestic species such as big-headed ant (Pheidole megacephala), ghost ant (Tapinoma melanocephalum) and crazy ant (Paratrechina longicornis) were increased. The methoprene bait also provided excellent performance against the big-headed ant, Pheidole megacephala, but they did not reduce T. melanocephalum and P. longicornis numbers. Hydramethylnon bait was ineffective against big-headed ant in this study.
