Apis florea has a wide distribution in southeast Asia, where it is the dominant honey bee species. It is an excellent colonizer, suggesting advanced behavioral plasticity. Using the proboscis extension response (PER) conditioning method, we investigated A. florea associative olfactory learning ability and compared it to the learning performances of Apis mellifera. A. florea workers reacted to pure odorant (conditioned stimulus) only when it was delivered in paired associations with sucrose rewards (unconditioned stimulus), and discriminated between a rewarded and unrewarded odor. Moreover, A. florea levels of acquisition in olfactory associative learning were higher in our study than those of A. mellifera, and they showed better retention of learning after 24 h than A. mellifera. Our results show that A. florea can be studied using PER procedures, enlarging the scope for future comparative studies of associative olfactory learning ability in bees.
