Abstract Chemical communication underlies the sophisticated colony organization of social insects. In these insects, cuticular hydrocarbons (CHCs) play central roles in nestmate, task, and caste recognition, which contribute to maintenance of the social and reproductive division of labor. Queen-specific CHCs reflect queen fertility status and function as a queen recognition pheromone, triggering aggregation responses around the queens. However, there are only a few studies about the royal recognition mechanism in termites, and particularly, no study has reported about queen-specific CHCs in the species using asexual queen succession (AQS) system, in which the primary queen is replaced by neotenic queens produced parthenogenetically. In this study, we identified the CHC pheromone for neotenic queen recognition in the AQS termite species Reticulitermes speratus. Gas chromatography-mass spectrometry analyses revealed that the relative amount of n-pentacosane was disproportionately greater in the CHC profiles of queens than in the CHC profiles of kings, soldiers, and workers. Furthermore, we investigated the cuticular chemicals of the queen aggregate workers; bioassays demonstrated that n-pentacosane shows a worker arrestant activity in the presence of workers’ cuticular extract. These results suggest that R. speratus workers identify whether each individual is a neotenic queen by recognizing the relatively higher ratio of n-pentacosane in the conspecific CHC background. Moreover, they suggest that termites have evolved queen recognition behavior, independently of social hymenopterans.
