Kurzbeschreibung (Abstract)
Army ants are keystone species in many tropical ecosystems. Yet, little is known
about the chemical compounds involved in army ant communication. In the present
study, we analyzed the volatile mandibular gland secretions—triggers of ant alarm
responses—of six Neotropical army ant species of the genus Eciton (outgroup:
Nomamyrmex esenbeckii). Using solid-phase microextraction, we identified
12 chemical compounds, primarily ketones with associated alcohols, one ester and
skatole. Most compounds were shared among species, but their relative composition
was significantly different. By comparing chemical distances of mandibular gland
secretions to species divergence times, we showed that the secretions’ compositions
are not strictly determined by phylogeny. By identifying chemical bouquets of seven
army ant species, our study provides a valuable comparative resource for future
studies aiming to unveil the chemicals’ precise role in army ant alarm
communication.
