Stingless bees use chemical signals to communicate nestmates the location of rich food sources. Such information may be intercepted by conspecifics from other colonies. In this study, we investigated if chemical information from non-nestmates can be used to orient foragers of the stingless bee Scaptotrigona mexicana to food sources. In the first experiment, foragers were exposed to feeders that were differentially odor-marked by nestmates and non-nestmates, and their preferences for both types of feeders were recorded. In a second experiment, we marked different feeders with mandibular or labial gland extracts of nestmates and non-nestmates. Results from the first experiment indicate that foragers were able to associate odor marks from non-nestmates with rich food sources. In the second experiment, we observed that foragers did not differentiate between the gland extracts of nestmates and those from non-nestmates. We discuss these findings within a behavioral and ecological framework. Inglés
