Trophallaxis and prophylaxis: social immunity in the carpenter ant Camponotus pennsylvanicus.

In social insects, group behaviour can increase disease resistance among nest-mates and generate social prophylaxis. Stomodeal trophallaxis, or mutual feeding through regurgitation, may boost colony-level immunocompetence. We provide evidence for increased trophallactic behaviour among immunized workers of the carpenter ant Camponotus pennsylvanicus, which, together with increased antimicrobial...

Octopamine reverses the isolation-induced increase in trophallaxis in the carpenter ant Camponotus fellah.

Social deprivation is an unusual situation for ants that normally maintain continuous contact with their nestmates. When a worker was experimentally isolated for 5 days and then reunited with a nestmate, she engaged in prolonged trophallaxis. It is suggested that trophallaxis allows her to restore a social bond with her nestmates and to re-integrate into the colony, particularly via the exchang...

A new carpenter ant, Camponotus parabarbatus (Hymenoptera: Formicidae) from India

A new species of carpenter ant, collected in the Shivalik range of Himalaya is described and illustrated based on the worker and gyne castes under the name Camponotusparabarbatus sp. n. Presence of dense, short setae on gena and ventral surface of head resembles it most to Camponotusbarbatus Roger, 1863 distributed in Southeast Asia. A regional identification key of Camponotus species is provid...

Antennal RNA-sequencing analysis reveals evolutionary aspects of chemosensory proteins in the carpenter ant, Camponotus japonicus

Chemical communication is essential for the coordination of complex organisation in ant societies. Recent comparative genomic approaches have revealed that chemosensory genes are diversified in ant lineages, and suggest that this diversification is crucial for social organisation. However, how such diversified genes shape the peripheral chemosensory systems remains unknown. In this study, we an...

Social Prophylaxis: Group Interaction Promotes Collective Immunity in Ant Colonies

Life in a social group increases the risk of disease transmission. To counteract this threat, social insects have evolved manifold antiparasite defenses, ranging from social exclusion of infected group members to intensive care. It is generally assumed that individuals performing hygienic behaviors risk infecting themselves, suggesting a high direct cost of helping. Our work instead indicates t...
