Abstract

This investigation shows that olfactory learning can be involved withfood identification. An experimentally induced food preference can beobtained by presenting a scented food to newly hatched workers of Lasius niger (L. ) (Hymenoptera Formicidae). Ten colonies were followed from their foundation. From the emergence of the first workers, the colonies were fed with a flavoured (anise) sugar solution (0.5M sucrose) during 1 month. After 3 months of hibernation without food, the colonies were submitted to a choice test. The preference for the scented foodindicates the existence of a ''pre-hibernal learning'' process with long term effects. Older foundations which were exposed to the flavoured food after the 3 months hibernation period preferred the known food,but the preference was less strong than that shown by the first group. Finally, mature workers from adult colonies, submitted to the same treatment, did not respond to the olfactory cues and exhibited no food preference. These results suggest the existence of an early learning period for food odour.
