The parasitic phorid flies, Pseudacteon tricuspis and Pseudacteon curvatus, were found to be significantly attracted to fire ants that had been electrically stimulated to release exocrine gland products (semiochemicals). A series of behavioral bioassays were used to identify the pheromonal response and source of the kairomones that attract the parasitic flies. This work may have consequences in phorid fly rearing and for detection in the field.
