Invasion of Polygyne Fire Ants Decimates Native Ants and Disrupts Arthropod Community
TLDR
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
Intercontinental Differences in the Abundance of Solenopsis Fire Ants (Hymenoptera: Formicidae): Escape from Natural Enemies?
Center for Medical Agric. and Veterinary Entomology USDA-ARS, P.O. Box 14565, Gainesville, FL 32604
FIRE ANT MOUND DENSITIES IN THE UNITED-STATES AND BRAZIL (HYMENOPTERA, FORMICIDAE)
TLDR
These data are consistent with the hypothesis that North American populations of S. invicta have escaped natural biological control; however, cultural and climatic factors are also likely explanations. Expand
Impact of temperature on colony growth and developmental rates of the ant, Solenopsis invicta
TLDR
It appears that temperature-adjusted development rates of ants and other social Hymenoptera are quite similar, and Nanitic brood developed about 35% faster than did minor worker brood, an important benefit for founding colonies. Expand
Foraging in Solenopsis invicta (Hymenoptera: Formicidae): effects of weather and season.
Foraging activity of the red imported fire ant, Solenopsis invicta Buren, was monitored at bait traps for 1 yr to determine how weather and season affected foraging. Soil temperature at 2 cm was theExpand
The little fire ant, Wasmannia auropunctata: distribution, impact, and control.
TLDR
The little fire ant, Wasmannia auropunctata, has been increasing in importance as an exotic pest and the only hope for long-term control appears to be classical biocontrol. Expand
BIOLOGY AND BEHAVIOR OF PSEUDACTEON DECAPITATING FLIES (DIPTERA: PHORIDAE) THAT PARASITIZE SOLENOPSIS FIRE ANTS (HYMENOPTERA: FORMICIDAE)
Larvae of phorid flies in the genus Pseudacteon have the unusual habit of decapitating fire ant workers and pupating inside the empty head capsule which they use as a pupal case. Flies in this genusExpand
Foragers of the harvester ant, Pogonomyrmex owyheei: a disposable caste?
TLDR
It is proposed that P. owyheei has evolved a disposable forager strategy that tolerates high forager mortality and the large reservoir of interior workers required by this strategy may also inhibit the evolution of physically specialized interior worker castes. Expand
Solenopsis (Hymenoptera: Formicidae) Fire Ant Reactions to Attacks of Pseudacteon Flies (Diptera: Phoridae) in Southeastern Brazil
TLDR
The existence of phorid-specific defenses indicates that Pseudacteon phorids exert substantial evolutionary pressure on South American fire ant populations. Expand
Potential Global Range Expansion of the Invasive Fire Ant, Solenopsis invicta
TLDR
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
