Short-term population redistribution of Pseudacteon tricuspis (Diptera: Phoridae) from point source releases.

There is a need for quantitative data on patterns and rates of movement of organisms to understand their movement behavior and predict their rates of spread. Opportunities for studying movement of biological control agents are presented during release programs. However, despite these opportunities, patterns and range of dispersal are often not considered.

Fire ant decapitating fly cooperative release programs (1994-2008): two Pseudacteon species, P. tricuspis and P. curvatus, rapidly expand across imported fire ant populations in the southeastern United States.

Natural enemies of the imported fire ants, Solenopsis invicta Buren S. richteri Forel (Hymenoptera: Formicidae), and their hybrid, include a suite of more than 20 fire ant decapitating phorid flies from South America in the genus Pseudacteon. Over the past 12 years, many researchers and associates have cooperated in introducing several species as classical or self-sustaining biological control agents in the United States.

Sampling and dynamics of Pseudacteon tricuspis (Diptera: Phoridae) in Louisiana.

The population dynamics of a fire ant (Solenopsis invicta Buren) parasitoid (Pseudacteon tricuspis Borgmeier) was studied in Louisiana. The objectives of this study were to understand the daily and seasonal population dynamics of P. tricuspis in the context of environmental variables, determine whether P.
