Zusammenfassung

Ants use cuticular hydrocarbons (CHC-proWles) as multicomponent recognition cues to identify colony members (nestmates). Recognition cues (label) are thought to be perceived during ant–ant encounters and compared to a neuronal template that represents the colony label. Over time, the CHC-proWle may change, and the template is adjusted accordingly. A phenotype mismatch between label and template, as happens with CHC-proWles of foreign workers (nonnestmates), frequently leads to aggressive behavior. We investigated the template reformation in workers of the carpenter ant Camponotus Xoridanus by masking their antennae with postpharyngeal gland (PPG) extracts from nestmates or non-nestmates. The behavioral response of manipulated workers encountering unmanipulated workers was measured independently after 2 and after 15 h. After 2 h of incubation, workers treated with either of the two PPG-extracts showed low aggression towards nestmates and high aggression towards non-nestmates. In contrast, after 15 h of incubation, workers treated with non-nestmate PPG-extract showed low aggression towards both nestmates and non-nestmates. The slow (>2 h) adjustment of the template indicates a reformation localized in the central nervous system rather than in chemosensory neurons. In addition, our data show that template adjustment to a new CHC-proWle does not impair the assessment of the old CHC-proWle as nestmate label.
