Abstract

Abstract. Under an LD 12:12h photoregime at constant temperature, parturition in Glossina morsitans centralis is a gated event occurring late in the afternoon. When flies are switched to continuous light the rhythm quickly dampens, but its persistence for at least two 24‐h cycles beyond the final scotophase suggests the rhythm has a circadian basis. A weak rhythm appears after 7 days of continuous light, perhaps in response to the daily disturbance caused by feeding. Return of the flies to LD 12:12h restores the rhythm after exposure to a single scotophase. Copyright © 1992, Wiley Blackwell. All rights reserved
