Abstract - Foragers of Trigona species were trained to artificial feeders associated with either yellow or blue colors, and the bees learned to associate the visual cues with a food reward. While feeding, foragers marked the plastic dishes with odors, which were later recognized by their nestmates. Odors left by foragers from different colonies of a single species elicited a positive response, while odors left by foragers of a different species elicited no noticeable response.
