Résumé : Laboratory societies of Leptothorax unifasciatus reared for some years were used for respirometry studies. Respiratory rates were determined at six different temperatures for workers, for various larvae and for a whole society, each month during a period of more than a year 24-h cycles were also monitored. Respiration of a whole nest stresses the overestimation and underestimation of worker and larval respiratory rates respectively when they are separated from their society. It was not possible to observe any circadian rhythm of respiration in a whole society at constant temperature. However, respiratory rates exhibit a clear annual cycle. This cycle, associated with a high Q 10 in lowest temperature intervals, is regarded as an acclimatory response of L. unifasciatus to the cold seasons of Belgium. © 1991.
