Abstract

Honeybees must track changing distributions of food resources in their environment. We evaluated the genetic basis for interindividual differences inthis ability by selecting lines of honeybees that differed in their tendency to reverse a learned discrimination between two odours. We show that individual variation in reversal learning performance, which is an analogue ofnatural foraging problems such as risk sensitivity, has a heritable component. Selection on drones, which are haploid, was sufficient to obtain a significant selection response after a single generation. In addition, worker age and/or task specialization, in terms of performance of housekeeping versus outside duties, is a source of environmental control over expression ofreversal performance. Finally, we identified a correlated response in latent inhibition, in which pre-exposure to a conditioned stimulus (CS) retardslearning about that CS when it is subsequently paired with reinforcement. From an ecological standpoint, our results suggest that colonies that contain a variety of genetic lineages may be able to target foragers to learningtasks in which they are genetically predisposed to do well.
