Abstract : In order to examine whether Nannotrigona testaceicornis deposits chemical attractants at a food source we made the bees choose between a feeder where nestmates had fed before and a clean unused feeder. 86 ± 5% of the bees chose the used feeder over the clean one. The attractiveness of the used feeder was reduced but not lost when the sugar water itself was scented by adding rosewood essence. When presenting the bees at a known feeding site a choice between a feeder on which 20 bees had walked incidentally at the nest entrance independent of food uptake and a clean feeder, a significant majority of bees chose the first one. Obviously, Nannotrigona testaceicornis leaves chemical cues on any object it walks on. These cues also attract bees from other nests of the same species and thus are not colony-specific.
