Range expansion of the fire ant decapitating fly, Pseudacteon tricuspis, eight to nine years after releases in North Florida
Florida Entomologist 89 (4), 536-538
Abstract: In the fall of 2005 and the spring of 2006, the fire ant decapitating fly Pseudacteon tricuspis (Diptera: Phoridae) was observed 145-275 km out from the original release sites in northern Florida, occupying an area of about 86,500 km². Average expansion rates of 26-57 km/year were considerably faster than previous observations. Considering these rates and other releases, we estimate that almost all of the state of Florida will harbor resident populations of P. tricuspis in the next 3 to 5 years.
