Red Imported Fire Ant Impacts on Northern Bobwhite Populations

The stability of Northern Bobwhite (Colinus virginianus) populations in Texas, where high density polygyne red imported fire ants (Solenopsis invicta) account for >50% of all (S. lnvicta) colonies, has been cited as a reason to repudiate impacts by this exotic species on Northern Bobwhite. We used two approaches to investigate the relationship between red imported fire ants and Northern Bobwhit...

Raft Formation by the Red Imported Fire Ant, Solenopsis invicta

The raft behavior of the invasive red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), has been documented for over a century. However, no rigorous tests have been performed elucidating the structure, limits, and important characteristics of this behavior. Rafting makes S. invicta competitive in both native and foreign environments. Further understanding of this behavior w...

Beauveria bassiana as a Biocontrol Agent Against the Red Imported Fire Ant

Major Accomplishments to date: 1. Genetic Manipulations. The fungal transformation expression vector, pBARGPE1 was provided by Dr. Krishna Podila, Michigan Technological University. The vector had the Aspergillus nidulans gpdA promoter and the A. nidulans trpC terminator flanking a multiple cloning site. The ß-glucuronidase gene (GUS) was provided by Dr. Randy Allen, Texas Tech University. The ...
