Abstract Seasonal studies on a 1,200-ha isolated infestation of Solenopsis invicta Buren located in McMinn County, TN, were initiated in 1993 and continued through 1997. Winter survivability was evaluated and compared with a southern Mississippi site. The impact of S. invicta on local myrmecofauna was compared with a Tennessee non-infested site. Data collected over four winters indicate that consecutive days at a low ambient air maximum temperature is more indicative of S. invicta winter… Expand

A conservation study was conducted at Camp Swift, Bastrop County, Texasto to determine if the red imported fire ant, Solenopsisinvicta, could be selectively managed to protect endemic ant diversity, and resulted in significantly higher ant diversity in the area where S. invicta was managed by prescription bait treatments.

A Climate Model of the Red Imported Fire Ant, Solenopsis invicta Buren (Hymenoptera: Formicidae): Implications for Invasion of New Regions, Particularly Oceania
It is shown how the response of a species to climate can be synthesized from field observations to provide useful insights into its population dynamics and provide a basis for making decisions on regional management of invasive species and an informative context for local studies. Expand
Survival of Imported Fire Ant (Hymenoptera: Formicidae) Species Subjected to Freezing and Near-Freezing Temperatures
The hypothesis that extended cold injury causes winter kill of fire ants, and may partially explain the distribution of fire ant species in the United States, is supported. Expand
Potential Global Range Expansion of the Invasive Fire Ant, Solenopsis invicta
A dynamic, ecophysiological model of colony growth is used to predict the potential global range expansion of this invasive species, S. invicta, which has diverse detrimental impacts on recipient communities and has the potential to colonize numerous other regions. Expand
Relative risk of invasive ants (Hymenoptera: Formicidae) establishing in New Zealand
Comparing the climate in New Zealand and its outlying islands to that found in the current native and introduced ranges of 12 tramp ant species is compared using the climate module of BIOSECURE, a risk assessment tool to assess if distribution records alone provide useful establishment predictions.

Modeling Temperature-Dependent Range Limits for the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the United States
A dynamic model of colony growth with two time steps per day was formulated that operates by colony area, S, and alate production, a to predict the future range of the fire ant Solenopsis invicta Buren within the United States based on climate and its current extreme distributions. Expand
It is found that the northernmost colonies of the imported red fire ant had higher mean supercooling points than the southernmost colonies, and there was little variation in head capsule widths of the minor workers that were measured. Expand
Interaction of Hybrid Imported Fire Ants (Solenopsis invicta × S. richteri) with Native Ants at Baits in Southeastern Tennessee
The results suggest that, like the red imported fire ant, Solenopsis invicta, the hybrid fire ant outcompetes native ants in disturbed habitats. Expand
Worker Size, Geographical Distribution, and Introgressive Hybridization of Invasive Solenopsis invicta and Solenopsis richteri (Hymenoptera: Formicidae) in Tennessee
The similarity in average worker size among hybrid colonies with a wide range of cuticular hydrocarbon and venom alkaloid values suggests introgression was not impacting ant size in colonies sampled throughout Tennessee. Expand
Red Imported Fire Ant Impacts on Upland Arthropods in Southern Mississippi
Red imported fire ants (Solenopsis invicta) have negative impacts on a broad array of invertebrate species resulting in a potential loss of both species and function and were negatively correlated with fire ant abundance. Expand


Survival of the Red Imported Fire Ant (Hymenoptera: Formicidae) on the Texas High Plains
An isolated population of the red imported fire ant, Solenopsis invicta Buren, was discovered in Lubbock, TX, during August 1985. This find represented the northwesternmost known population in NorthExpand
Invasion of Polygyne Fire Ants Decimates Native Ants and Disrupts Arthropod Community
The ecological impacts of a polygyne fire ant invasion on ants and other surface—active arthropods at a field station in central Texas indicate that polygyn fire ants pose a substantial threat to the biodiversity of native arthropod communities. Expand
Preliminary studies on the ants of Florida soybean fields
Fifty species of ants representing 6 subfamilies were present in Florida soybean fields. An attempt was made to determine both the niche and importance of individual species. A somewhat less diverseExpand
Overwinter Survival of the Red Imported Fire Ant in Central Georgia
Survival of colonies of the red imported fire ant, Solenopsis invicta Buren, near its current northern range in the Georgia Piedmont during Oct.–Feb., 1975–76 was 96–100%. Workers moved broodExpand
Overwinter Survival of the Red Imported Fire Ant: Effects of Various Habitats and Food Supply
Survival of colonies of the red imported fire ant, Solenopsis invicta Buren, during the record-breaking low winter temperatures of 1976–77 was low (4–42%) in the Piedmont Plateau in central Georgia.Expand
Avermectin B1a: highly potent inhibitor of reproduction by queens of the red imported fire ant (Hymenoptera: Formicidae).
Overall effects of avermectin B1a baits were determined with a population index method that gave a greater numerical value to colonies with functioning queens, as evidenced by the presence of worker brood. Expand
