| Abstract: | ABSTRACT. Individual worker ants isolated in an actograph exhibit circadian rhythms of locomotor activity. Entrainment occurs more readily in LD 18:6 h than in LD 12:12 h. The ants are either light-active or dark-active. Phase angle and duration of activity is influenced by photoperiod. |
