Behavioural plasticity in ectatomma ruidum roger (Hymenoptera, ponerinae), in a homospecific interactive situation
A laboratory study of interaction between homospecific colonies of the ant Ectatomma ruidum Roger is reported. Different colonies of this neotropical ponerine can share a restricted space without giving rise to serious conflict. During interaction intrusions of alien workers in homospecific nests were examined and a new phenomenon was also observed: the kidnapping of callow workers and brood by workers belonging to alien colonies. According to their characteristical patterns, we considered kidnapping to be a primitive form of intraspecific slavery, originating from interactive situation in high density population.
