Summary:
We investigated the incidence of inquiline ants and of arboreal-nesting ants on a community of three arboreal-nesting termites living in New Guinea coconut plantations. Inquiline ants were present in 10 % of Microcerotermes biroi nests and in 4 % of Nasutitermes princeps nests. Live termite nests inhabited by the most common inquiline ant, Camponotus sp. A, were generally left by the ant after several months. In some nests, Camponotus sp. A was observed coexisting with its host during the whole observation period (3 years). Therefore, Camponotus sp. A was apparently an opportunistic inquiline which did not affect significantly the mortality of termite colonies. The arboreal-nesting ant, Crematogaster irritabilis, was locally found occupying up to 99 % of the trees present in 1 ha plots. In such hot spots, the overall abundance of termites was approximately half that of plots devoid of Crematogaster irritabilis. The high density of Crematogaster irritabilis may be an important limiting factor for the termite assemblage, by hastening the death or hindering the establishment of arboreal termite colonies.
