| Résumé : | The flower constancy of honeybees on successive days has been studied by removing and identifying pollen collected by marked pollen-gatherers. Removing pollen from the bees decreased their tendency to collect it later; chilling the bees before marking did not influence their foraging behaviour; neither treatment affected their constancy to the kind of pollen collected. No sequence of nectar or pollen collection with age of bee, was found. In each experiment most of the bees collected only a few of the pollens available to them. Bees collecting the most common pollens tended to be the most constant. In general, the proportion of bees collecting their original pollen decreased as the number of foraging days increased, and only about half were doing so after 1 week; the rate of decrease differed in different experiments. No bee regularly collected different pollens at different times of the day. When the pollen they were accustomed to collect was unavailable for a day, most foraged for nectar only or remained at home. Most bees that changed to another pollen probably did so when the pollen they had previously collected was scarce or unattractive for longer periods. About 6% of the loads each contained more than one species of pollen. Bees that collected mixed loads were more inclined to do so later; probably they were dissatisfied with the crops they were working and were sampling others. 4. When a colony was moved to another site with a similar flora, the bees tended to visit the same species as before, but when one species predominated, bees that had not visited it before tended to do so. |
