Relevance/Implication of Project:
Detailed knowledge of the geographical relations of imported fire ants and native ants is critical for the application of phorid flies in biological control. Likewise, information on the geographical ecology and genetics of native and introduced phorid flies provides an important basis for interpreting the success or failure of introduction attempts.

Summary of Work to be Done:
Existing surveys of imported fire ants and native ants are not fine scale enough for use in detailed ecological studies, such as monitoring ant community changes after biocontrol attempts. Moreover, virtually no information exists on the geographical ecology and genetics of Pseudacteon. Such information is necessary for understanding any genetic basis for geographical patterns of introduction success and failure, for understanding the sources of flies colonizing a new site, and for detecting any possible hybridization with native Pseudacteon species.
