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. Do you have a Fruit Fly Problem or a Phorid Fly problem? She uses the stabbing part of her ovipositor to pierce the thorax and implant the egg. Flies of the genus Pseudacteon are members of the family Phoridae, commonly known as scuttle flies, hump-backed flies, and phorid flies (Disney 1994). 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. 6:10. Many field-reared flies have been found attacking ants and laying eggs to start a second generation. The larva that hatches burrows into the ant’s head, where it grows and eventually releases enzymes that cause the ant head to fall off. "In action, the phorid hovers over the fire ant like a tiny helicopter, darting in at a tenth of a second, injecting a torpedo-shaped egg into the ant’s body, before buzzing off to attack the next ant in the fly’s brief life span.

Phorid flies in the genus Pseudacteon are 1) highly specific parasitoids, 2) broadly distributed across geography and climate, and 3) strongly affect fire ant foraging behavior. phorid flies effectively control the size of fire ant populations because. Abstract Aim Saevissima group fire ants, Solenopsis richteri and S. invicta, have become serious pests when introduced from Argentina and Brazil to other continents. Maggots of these miniature flies develop in the heads of fire ant workers, decapitating their host upon pupation. It’s a kind of ant. First, a female fly injects an egg into the fire ant’s body. There are other species of red ants, by the way, including some that are native to the U.S. A discussion of these, their habits, their identification, their similarities to and differences from the imported fire ants, would also be in order. Once injected, the egg hatches and the larva travels through the ant’s neck and skull, where it eats the brain. These flies lay their larvae on the ants. Natasha J. Mehdiabadi. Fire Ants vs. My Hand - Duration: 16:56. Parasitoid phorid flies are the scourge of many ant species. Browse more videos. The red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), is an invasive species of south‐eastern U.S.A. They actually help foster the phorid fly effect because the phorid fly works by shifting the balance of competition. Apparently the impacts of this fly on fire ant populations were less than the 10-30% sensitivity of the field trials. Excerpt from the National Geographic Explorer film Fire Ants: Texas Border Massacre about the invasive red fire ants (Solenopsis invicta). Flies Captured on Video Turning Fire Ants Into Zombies from College of Natural Sciences on Vimeo.. Texas has a fire ant problem.A fire ant is not an ant that is on fire. The presence of Pseudacteon phorid flies, in addition to having direct mortality effects on their host ants, modifies foraging behavior and disrupts interspecific competition between host species and other ant species in the community. The native fire ants have heads larger than their bodies, while the heads of imported fire ants are about the same size as their bodies. Fire ant populations varied greatly over time, but a series of statistical tests revealed no effect of phorid parasitism pressure on fire ant density or activity. The female phorid fly swoops in on a fire ant and, in less than a tenth of a second, injects an egg into the ant's midsection.

In their native home of South America, phorid flies are natural enemies of fire ants, so researchers at the University of Florida considered them a good solution to fire ant control, first releasing them in 1998 in Gainesville, then releasing them into other parts of the state and into Georgia until 2008. The genus Pseudacteon, or ant-decapitating flies, of which 110 species have been documented, is a parasitoid of ants. However, this will be the first release in the north central Texas area.
