There are two related components to this project; 1) a phorid fly (Pseudacteon spp.) tracking program, and 2) a predictive decision and management support program. Each component of this GIS (geographic information systems) project is structured as a stand alone program with supporting data for the predictive program relying on data collected for the tracking component. The tracking component of the project is being initiated in 2003, the first year of the multi-year project. The tracking program uses GIS technology to display and organize information on phorid fly releases within states. Data on phorid fly releases and site characteristics are collected by state collaborators, using GIS/PDA handheld devices. The goals of the project are to monitor releases and identify important biotic and abiotic factors influencing successful establishment and spread of phorid flies in imported fire ant (Solenopsis spp.) infested areas. The tracking component of the project, presented in this meeting, is structured to be delivered, as a web-based application, to state collaborators as a geo-referenced tracking system.

Species 1: Hymenoptera Formicidae Solenopsis invicta (red imported fire ant)
Species 2: Diptera Phoridae Pseudacteon tricuspis (decapitating fly)
