| Research Abstract |
Ants have highly elaborate pheromonal communication systems to maintain a complex society. Cuticular hydrocarbons (CHCs) found on the cuticle surface, play critical roles for nestmate recognition. It have been suggested that the ant, Camponotus japonicus, detects the colony-specific CHC profile by directly contacting another ant with their antennal basiconic sensilla. Here, we found that the ant can recognize nestmate by volatilized extracts derived from the cuticle surface. This result suggests that the ants recognize nestmate using olfactory cues. Therefore, we performed extracellular recordings from sensory neurons in a basiconic sensillum, and found that each sensillum responded varied olfactory molecules. In the ants, sensory information received by basiconic sensilla is processed in specific brain regions. Finally, to reveal the brain evolution of social insects, we developed immunostainings and compared brain structures among many hymenopteran insects.
