Its current specific name invicta was given to the ant in 1972 as a separate species. This paper provides a synthesis of the ecological impact of phorid fly parasitoids on ants. While several studies show a decrease in resource acquisition by fire ants in the presence of phorid flies, the ultimate impact of phorid flies on fire ant populations has yet to be demonstrated in the field. Both sexes of all three Pseudacteon species were attracted to low doses of the fire ant alarm pheromone or venom alkaloids (i.e. “Ranchers can treat large areas with the bait, knocking populations to manageable numbers,” Barr said.

Multiple species of Pseudacteon phorid flies (Diptera: Phoridae) are currently being released throughout the southern United States to aid biological control of red imported fire ants, Solenopsis invicta Buren (Hymenoptera: Formicidae). A gravid female phorid fly seeks out foraging ants to parasitize, and most flies appear to specialize on specific species of ants or at least a group of congeners. Meanwhile, other studies will look at changes within fire ant colonies that may occur if flies reduce resources reaching the colonies. The phorid fly, Pseudacteon tricuspis Borgmeier, is an introduced parasitoid of imported fire ants, Solenopsis spp., in the USA. So far, their spread has been limited only by cold weather. The common means of parasitism, and until recently thought to be the only method, is as follows. Multiple species of Pseudacteon phorid flies (Diptera: Phoridae) are currently being released throughout the southern United States to aid biological control of red imported fire ants, Solenopsis invicta Buren (Hymenoptera: Formicidae). Phorid flies also represent a new and hopeful means by which to control fire ant populations in the southern United States, where some species of fire ants were accidentally introduced in the 1930s. The egg hatches and the larva wiggles into the ant’s head, where it grows. When an opening arises, the flies dive-bomb sharply towards an unwitting ant, piercing an egg inside their body using their uniquely adapted ovipositor (the egg-laying ‘sting’).
