Visually guided decision making in foraging honeybees.

Zhang S, Si A, Pahl M - Front Neurosci (2012)

Bottom Line: The trained animals learn how to solve a task, and do so with a high accuracy, but when they are presented with a new variation of the task, they apply the learnt rules from the earlier setup to the new situation, and solve the new task as well.Honeybees therefore not only feature a rich behavioral repertoire to choose from, but also make decisions most apt to the current situation.The experiments in this review give an insight into the environmental cues and cognitive resources that are probably highly significant for a forager bee that must continually make decisions regarding patches of resources to be exploited.

ABSTRACT
Honeybees can easily be trained to perform different types of discrimination tasks under controlled laboratory conditions. This review describes a range of experiments carried out with free-flying forager honeybees under such conditions. The research done over the past 30 or so years suggests that cognitive abilities (learning and perception) in insects are more intricate and flexible than was originally imagined. It has become apparent that honeybees are capable of a variety of visually guided tasks, involving decision making under challenging situations: this includes simultaneously making use of different sensory modalities, such as vision and olfaction, and learning to use abstract concepts such as "sameness" and "difference." Many studies have shown that decision making in foraging honeybees is highly flexible. The trained animals learn how to solve a task, and do so with a high accuracy, but when they are presented with a new variation of the task, they apply the learnt rules from the earlier setup to the new situation, and solve the new task as well. Honeybees therefore not only feature a rich behavioral repertoire to choose from, but also make decisions most apt to the current situation. The experiments in this review give an insight into the environmental cues and cognitive resources that are probably highly significant for a forager bee that must continually make decisions regarding patches of resources to be exploited.

Mentions: Srinivasan et al. (1998) explored this capacity by asking whether bees could learn to associate specific scents with specific colors. The apparatus consisted of a compound Y-maze, as in the above experiments, but with a single decision stage (Figure 10A). The sample stimulus, presented in the first cylinder, was a scent that was either lemon or mango. The decision stage offered a choice of two colors, blue or yellow. When the bees encountered lemon at the entrance, they had to learn to choose blue in the decision stage; when they encountered mango, they had to choose yellow. The bees learned this task very well (Figure 10B Experiment 1). The scent of lemon evidently evoked recall of blue, whereas mango triggered recall of yellow. Bees could also be trained to make the opposite associations: lemon with yellow, and mango with blue (Figure 10B, Experiment 2), as well as symbolic matches in the opposite direction (Figures 10C,D).
