Technical Abstract: The parasitic phorid fly, Pseudacteon tricuspis was found to be attracted to the volatile compounds released by shaken fire ant workers. Among the compounds released were alarm pheromones, venom alkaloids, and recruitment pheromones. In subsequent bioassays we eliminated poison sac contents and recruitment pheromones as possible attractants. We have demonstrated the involvement of alarm pheromones in the attraction of this phorid fly to their host fire ant.
