Implication

Longitudinal study demonstrates behavior-specific senescence across lifespan in male crickets, indicating reproductive and sleep declines occur independently of generalized movement loss.

Key Points

To longitudinally track and characterize multidimensional behavioral changes across the full adult lifespan in the cricket Gryllus bimaculatus.
Continuously recorded video and applied DeepLabCut markerless pose estimation to track eight adult male crickets (N=8) under a 12:12 h light–dark cycle across their entire adult lifespans.
Classified behavioral profiles—locomotion, resting, sleep-like state (SLS), feeding, drinking, and calling—across early, mid, and late lifespan stages.
Locomotion, resting, SLS, and calling changed significantly across lifespan stages and light-dark phases, whereas feeding and drinking behaviors remained stable with age.
Age-related reduction in male calling correlated with increased sleep-like state rather than locomotion, indicating reproductive communication decline is independent of general locomotor decline.
