Predation by Megaponera foetens (Fabr.) (Hymenoptera: Formicidae) on termites in the Nigerian southern Guinea Savanna.

At Mokwa, in the Nigerian southern Guinea Savanna, Macrotermitinae are the only recorded prey of the obligate termite predator, Megaponera foetens. The main prey species is Macrotermes bellicosus (141 termites m-2 a-1) followed by Odontotermes spp. (42 termites m-2 a-1). Predation on other species, Ancistrotermes cavithorax, Macrotermes subhyalinus and Microtermes spp., amounts to only 10 termites m-2 a-1. Macrotermes bellicosus is not the most abundant termite in the primary savanna. It is concluded that factors including termite abundance, termite foraging regimes and seasonality, termite biomass and the reactions of the ants to the termites and their products are involved in successful predation of termites by Megaponera.
