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...

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...

Residual Toxicity of Some Fluoroaliphatic Sulfones to the Red Imported Fire Ant

Thirty-six fluoroaliphatic sulfones were tested to determine their residual toxicity to Solenopsis invicta Buren in soil. Six of the compounds gave >90% kill of the ants after they were exposed for 4 days at 10 ppm. When tested at 1.0 ppm, only one compound, AI3-10841, gave appreciable mortality. This compound was tested at 10 ppm in soil held outdoors under ambient summer conditions. Mortality...
