This study shows that nematode infections in ants alter chemical signatures and provoke aggression, but do not affect nestmate recognition.

The paper identifies a larval pheromone in clonal raider ants that suppresses adult egg laying, linking offspring presence to parental reproductive suppression.

This study shows that ants can acquire ABPV, incur fitness costs, and transmit the virus within colonies without supporting replication.

The paper tests if high-risk social insect workers invest more in immune defenses but finds no evidence for risk-dependent immune investment in clonal ants.

This study links division of labour to colony defence efficiency in clonal ants, showing that behavioural variation within colonies enhances defence effectiveness regardless of social environment.
