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.
Intercontinental Differences in the Abundance of Solenopsis Fire Ants (Hymenoptera: Formicidae): Escape from Natural Enemies?

FIRE ANT MOUND DENSITIES IN THE UNITED-STATES AND BRAZIL (HYMENOPTERA, FORMICIDAE)
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.
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 the…

The little fire ant, Wasmannia auropunctata: distribution, impact, and control.
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.
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 genus…

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.
An Overview of the Red Imported Fire Ant (Hymenoptera: Formicidae) in Mainland China
It has been predicted that most of mainland China is viable habitat for red imported fire ants, including 25 of 31 provinces, and the probable northern limit of expansion reaches Shandong, Tianjing, south Henan, and Shanxi provinces.
Solenopsis (Hymenoptera: Formicidae) Fire Ant Reactions to Attacks of Pseudacteon Flies (Diptera: Phoridae) in Southeastern Brazil
The existence of phorid-specific defenses indicates that Pseudacteon phorids exert substantial evolutionary pressure on South American fire ant populations.
