PLACES AND PATTERNS - A STUDY OF CONTEXT LEARNING IN HONEYBEES

To investigate the priming of memories by contextual cues, bees were t rained to negotiate two mazes in different places 25 m apart. In the f irst maze, bees flew leftwards when the inner wall of the maze was cov ered with 45 degrees stripes or rightwards when the inner wall was col oured yellow. In the second maze, bees flew rightwards on viewing 135 degrees diagonal stripes or leftwards on viewing blue. The trajectorie s evoked by 45 degrees or 135 degrees stripes were similar in both maz es. However, vertical stripes were treated like 45 degrees stripes in maze 1 and like 135 degrees stripes in maze 2. Contextual cues prime t he response to stripes that are oriented in the training condition for that site so influencing responses to stripes in closely neighbouring orientations. What objects in a bee's surroundings determine its sens e of place? Bees were trained to different visual patterns at two site s 40 m apart (A+ versus A- at site A, and E+ versus E- at site E). Awas preferred over A- and E+ was preferred over E- at both training si tes. A preference for A+ over E+ exhibited at site A dropped gradually with distance to suggest that spatial context includes both close and distant objects.
