Resumen:
In this study we
investigate associative learning related to food location in Vespula germanica
social wasps. Wasps were trained to associate a certain location with food, and
their behaviour after food displacement was recorded. The effect of a different
number of previous feeding experiences on the detection of the novel food
source was evaluated. When these wasps associated a certain location with food,
they returned to the original site despite the fact that food was no longer
available. This occurred even when a new food source was placed very close to
the learned location. The results demonstrate that this learning seems to
temporarily impair the detection of new food sources. We discuss how previous
experience seems to condition perception, delaying the detection of more
rewarding contexts.
