Age and rearing environment interact in the retention of early olfactory memories in honeybees
Due to the changing behavioral contexts at which social insects are exposed during the adult lifespan, they are ideal models to analyze the effect of particular sensory stimuli during young adulthood on later behavior. Specifically, our goal is to understand early influences on later foraging behavi...

Specifically, our goal is to understand early influences on later foraging behavior.

Due to the changing behavioral contexts at which social insects are exposed during the adult lifespan, they are ideal models to analyze the effect of particular sensory stimuli during young adulthood on later behavior. Specifically, our goal is to understand early influences on later foraging behavior.

By testing long-term memories (LTM) through a single PER test in workers of foraging ages (17-25 days), we found that retention of the early olfactory memories in honey bees is age-dependent and not time-dependent.
