Circadian rhythm is an important factor for long-distance movement in insect species. Previous studies have shown the relationship between movement and circadian rhythm, suggesting that movement has a genetic correlation with circadian rhythm. Present study investigated whether the period and amplitude (power) of circadian rhythm are influenced by the artificial selection of moving distance in the red flour beetle Tribolium castaneum. Our results indicated that the circadian rhythm did not differ between genetically longer and shorter moving distance populations, suggesting that the relationship between movement and circadian rhythm does not depend on a genetic correlation in T. castaneum.
