| Sumario: | Food scents circulating inside beehives influence foraging preferences in the field. However, the persistence and nature of the prior experience that lead to this biased response remain unknown. To determine how long honeybees show a food preference after experiencing a scented food inside the colony, we offered sugar solution scented into beehives. After all the combs of the experimental colonies were replaced, the landing responses of foragers were quantified in a two-scented-feeder situation outside the colony. We also tested whether bees exposed to a volatile compound inside the hive preferred a feeder scented with this odor to an unscented one. Results support the conclusion that the offering of a scented food enhanced the bias to this odor, whereas the volatile compound exposure caused a reduced landing response towards the scented option. These results suggest that olfactory experiences occurring within the beehive can promote changes in foraging preferences for several days. © 2008 INRA DIB-AGIB EDP Sciences. |
