  abstract = {{A}mong the factors driving the invasive success of non-indigenous species, the "escape opportunity" or "enemy release" hypothesis argues that an invader's success may result partly from less resistance from the new competitors found in its introduced range. {I}n this study, we examined competitive interactions between the little fire ant {W}asmannia auropunctata ({R}oger) and ant species of the genus {P}heidole in places where both are native ({F}rench {G}uiana) and in places where only species of {P}heidole are native ({N}ew {C}aledonia). {T}he experimental introduction of {W}. auropunctata at food resources monopolized by the {P}heidole species induced the recruitment of major workers only for the {G}uianian {P}heidole species, which were very effective at killing {W}asmannia competitors. {I}n contrast, an overall decrease in the number of {P}heidole workers and no recruitment of major workers were observed for the {N}ew {C}aledonian species, although the latter were the only ones able to kill the {W}asmannia workers. {T}hese results emphasize the inappropriate response of native dominant {N}ew {C}aledonian species to {W}. auropunctata and, thus, the importance of enemy recognition and specification in the organization of ant communities. {T}his factor could explain how invasive animal species, particularly ants, may be able to successfully invade species-rich communities.},
