![]() ![]() The flies are expensive to rear and require knowledge to establish successfully. It takes many Pseudacteon phorid flies or parasitized ants to establish a population released over a period of time (weeks). There are two laboratories leading research on parasitic phorid flies: The Imported Fire Ant and Household Insects research unit in Gainesville, Florida and the University of Texas at Austin Fire Ant Project.Ĭan I get phorid flies to release on my property to control fire ants? What laboratories lead research on parasitic phorid flies? Watch video of Pseudacteon phorid fly attacking a major imported fire ant worker (video by A. Pseudacteon species that attack fire ants in South America have been introduced into areas where Solenopsis invicta and Solenopsis richteri are invasive pests. Certain species of flies belonging to the genus Pseudacteon are known to attack fire ants ( Solenopsis spp.). At least 3,000 species have been described, although there are many more undescribed species. There are about 230 genera in the family Phoridae. The term phorid fly is used for any of the flies belonging to the family Phoridae. Efforts have been made to introduce natural enemies to the invasive ant populations in order to provide sustainable suppression. This situation is thought to arise because natural enemies (predators, parasites and pathogens) that keep populations low in South America were not imported along with this ant. In South America, the native habitat for imported fire ants (red and black), populations are much lower than populations in the southern United States and other areas where imported fire ants have been accidentally introduced (Porter et al. As such, it is the basis for many integrated pest management (IPM) programs. Self-sustaining biological control can be an effective and environmentally safe method to permanently control pests over wide areas. “There are much higher returns available from eradication options compared to suppression options, largely because suppression would still lead to large impacts by, especially on households and agriculture,” the report said.Classical or self-sustaining biological control is the use of imported natural enemies to suppress pests. The biggest cost would be to households, including the cost of pesticides, veterinary bills and electrical faults. Under the 48km scenario, the costs would be about $1.2bn a year. In the worst case, fire ants reach the Liverpool plains and the northern outskirts of Sydney in the same time period.īy 2035 the annual cost to the economy in the 5km invasion scenario was about $890m, increasing significantly year on year. In the first scenario, the pests will have reached high-value farmland in the Darling Downs by 2035.

Finds on the Gold Coast have raised concerns the pests are moving quickly towards New South Wales. Australian governments have a $400m eradication program but, despite the investment, red fire ants continue to spread.
