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.

Chemical communication is fundamental to success in social insect colonies. Species-, colony-, and caste-specific blends of cuticular hydrocarbons (CHCs) and other chemicals have been well documented as pheromones, mediating important behavioral and physiological aspects of social insects. More specifically, royal pheromones used by queens (and kings in termites) enable workers to recognize and care for these vital individuals and maintain the reproductive division of labor. In termites, however, no royal-recognition pheromones have been identified to date. In the current study, solvent extracts of the subterranean termite Reticulitermes flavipes were analyzed to assess differences in cuticular compounds among castes. We identified a royal-specific hydrocarbon—heneicosane—and several previously unreported and highly royal enriched long-chain alkanes. When applied to glass dummies, heneicosane elicited worker behavioral responses identical to those elicited by live termite queens, including increased vibratory shaking and antennation. Further, the behavioral effects of heneicosane were amplified when presented with nestmate termite workers’ cuticular extracts, underscoring the importance of chemical context in termite royal recognition. Thus, heneicosane is a royal-recognition pheromone that is active in both queens and kings of R. flavipes. The use of heneicosane as a queen and king recognition pheromone by termites suggests that CHCs evolved as royal pheromones ∼150 million years ago, ∼50 million years before their first use as queen-recognition pheromones in social Hymenoptera. We therefore infer that termites and social Hymenoptera convergently evolved the use of these ubiquitous compounds in royal recognition.

Queen signals are known to regulate reproductive harmony within eusocial colonies by influencing worker behavior and ovarian physiology. However, decades of research have resulted in the identification of just a few queen signals, and studies of their mode of action are rare. Our aim was to identify queen recognition signals in the halictid bee Lasioglossum pauxillum and to analyze caste differences in the olfactory perception of queen signals in L. pauxillum and the closely related species L. malachurum. We performed chemical analyses and bioassays to test for caste differences in chemical profiles and worker behavior influenced by queen-specific compounds in L. pauxillum. Our results indicated that caste differences in the chemical profiles were mainly attributable to higher amounts of macrocyclic lactones in queens. Bioassays demonstrated a higher frequency of subordinate behavior in workers elicited by queen-specific amounts of macrocyclic lactones. Thus, macrocyclic lactones function as queen recognition signals in L. pauxillum, as in L. malachurum. Using electrophysiological analyses, we have demonstrated that queens of both tested species lack antennal reactions to certain macrocyclic lactones. Therefore, we assume that this is a mechanism to prevent reproductive self-inhibition in queens. Our results should stimulate debate on the conservation and mode of action of queen signals.
