| description | Locomotor activity rhythms are crucial for foraging, mating and predator avoidance in insects. Although the circadian rhythms of activity have been studied in several termite species, the molecular mechanisms of circadian rhythms in termites are still unclear. In this study, we found that two termite species, <i>R. chinensis</i> and <i>O. formosanus</i>, exhibited clear circadian rhythms of locomotor activity in constant darkness along with rhythmically expressed core clock genes, <i>Cry2</i> and <i>Per1</i>. The knockdown of <i>Cry2</i> or <i>Per1</i> expression in the two termite species disrupted the circadian rhythms of locomotor activity and markedly reduced locomotor activity in constant darkness, which demonstrates that <i>Cry2</i> and <i>Per1</i> can mediate the circadian rhythms of locomotor activity in termites in constant darkness. We suggest that locomotor activity in subterranean termites is controlled by the circadian clock. |
