Colony reproduction in the tramp ant Technomyrmex vitiensis MANN, 1921 is characterized by the co-occurrence of dispersing winged queens and local, wingless, intermorphic reproductives, similar to other species of the T. albipes SMITH, 1861 group. A morphometric analysis of intermorphs and workers separated the two castes and developmental character of ocelli and size of compound eye clearly correlate with ovarian development. Intermorphs constitute a substantial proportion of the colony, but in our sample only a small fraction of intermorphs were inseminated despite the presences of winged males. Wingless males, which mate with intermorphs in other Technomyrmex species, have as yet not been found in T vitiensis. Our data support earlier findings from closely related Technomyrmex that reproduction is based on an opportunistic strategy enabling the species to rapidly colonize new habitat. An outbreak of a colony fragment into the walls of our laboratory was efficiently stopped by use of boric acid baits, indicating that trophallaxis is used to distribute food.
