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.

蚂蚁有高度复杂的信息素通讯系统来维持一个复杂的社会。表皮碳氢化合物（CHCs）发现在表皮表面，起着关键作用的巢识别。有人建议，蚂蚁，Camponotus的，检测殖民地特异性CHC的配置文件，直接接触另一个蚂蚁与他们的触角锥形感器。在这里，我们发现，蚂蚁可以识别巢友挥发提取物来自角质层表面。这一结果表明蚂蚁通过嗅觉线索来识别巢友。因此，我们进行了细胞外记录的感觉神经元在一个basiconic感器，并发现每个感器响应不同的嗅觉分子。在蚂蚁中，锥形感受器接收到的感觉信息在特定的大脑区域进行处理。最后，为了揭示社会性昆虫的脑进化，我们开发了免疫染色和比较许多hyperteran昆虫的脑结构。
