Abstract The ant Solenopsis invicta Buren has spread across the United States and is reported to have significantly reduced the diversity of the native ants. Much of this spread is occurring on land that has been repeatedly disturbed by continually changing land use practices. S. invicta seems to outcompete and eliminate other resident ant species. However, this inference may not be true because several resident native ant species are known to persist in S. invicta-infested areas. Thus, in this… 

Inability of Incipient Solenopsis invicta (Hymenoptera: Formicidae) Colonies to Establish in a Plot with a High Density of Solenopsis (Diplorhoptrum) Colonies

The results suggest that high density of at least one species of native ant can eliminate or at least reduce the establishment of small colonies of S. invicta that may have started to develop after the escape of the founding queen.

Aggressive Interactions Between Solenopsis invicta and Linepithema humile (Hymenoptera: Formicidae) Under Laboratory Conditions

Fire ant baits may have long-term effects on intercolonial aggression between S. invicta and L. humile, especially when Argentine ant populations are high in the summer.

Invasive interactions of Monomorium minimum (Hymenoptera:Formicidae) and solenopsis invicta (Hymenoptera:Formicidae) infected with thelohania solenopsae (Microsporida:Thelohaniidae) in the laboratory

S. solenopsae were not able to defend their colony or prevent competing ants from invading as well as uninfected S. invicta colonies, and M. minimum was the more invasive species when compared to S. Invicta.

Interaction between Monomorium minimum and healthy or Thelohania solenopsae infected Solenopsis invicta : a laboratory study

There is little evidence that these native ant species can eliminate RIFA colonies once they consist of a few defending workers, but there is a lot of interest in developing a biological control approach to RlFA management.

Native Ant Responses to Solenopsis invicta Buren Reduction Using Broadcast Baits

A temporary change in diversity was observed, indicating that use of a poison bait for S. invicta management benefited numerous resident species in the ant assemblage.

Impact of imidacloprid on new queens of imported fire ants, Solenopsis invicta (Hymenoptera: Formicidae)

Neonicotinoid insecticides are commonly used in managing pest insects, including the imported fire ant, Solenopsis invicta Buren. There is increasing evidence that neonicotinoid insecticides at

Impacts of invasive ants on native ant communities (Hymenoptera: Formicidae)

The most commonly documented consequence of alien ant invasions is the displacement and local extinction of native ant species. However, several processes may lead to low native ant diversity in the

The Initial Behavioral Sequences and Strategies of Various Ant Species During Individual Interactions with Solenopsis invicta

The behavior of individual ants during one-on-one interactions is studied to gain insight into how resident ant species behave when they encounter incipient red imported fire ant, Solenopsis invicta Buren colonies.

Red imported fire ants (Solenopsis invicta) and seasonality influence community refuge use

Investigating community-wide refuge-use patterns in the context of two important ecological factors: invasive species and seasonality found evidence for a negative effect of S. invicta on vertebrate refuge use that was also influenced by season.

Evaluating the effects of red imported fire ants (Solenopsis invicta) on juvenile Houston Toads (Bufo [=Anaxyrus] houstonensis) in Colorado County, TX

It is recommended that APCNWR be re-evaluated as a reintroduction site for Houston Toads and further studies are recommended to potentially broaden the regulatory definition of Houston Toad habitat beyond the current restrictive view of canopied forest alone.



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.

Ant predators of founder queens of Solenopsis invicta (Hymenoptera : Formicidae) in central Texas

Vials containing founder queens of the red imported fire ant, Solenopsis invicta Buren, were placed under the soil surface at four locations in central Texas to compare founder queen predation mortality and also to document ant predators of the queen.

Predators of Solenopsis invicta Queens Prior to Successful Colony Establishment

An investigation was made in north Florida of the biotic factors affecting female Solenopsis invicta Buren from the beginning of the nuptial flight until the emergence of minum workers in newly established colonies, finding that S. Invicta workers are again important.

Invasion of red imported fire ants (Hymenoptera: Formicidae): microgeography of competitive replacement

The invasion of Brackenridge Field Laboratory, Austin, Texas, by the multiple-queen form of the red imported fire ant, Solenopsis invicta Buren, was monitored for 3 yr. This invasion provides a rare

Predation on Founding Queens of Solenopsis Invicta by Workers of Conomyrma Insana

Solenopsis invicta Buren founding queens are especially vulnerable to predation during and following the nuptial flight. Conomyrma insana (Buckley) workers are effective predators of the queens in


The results of this study indicate that the impact of such invasive ants may be greatest during and shortly after the initial phase of an invasion.

Colony Reproduction by Budding in the Polygyne Form of Solenopsis invicta (Hymenoptera: Formicidae)

The total weights of the colonies increased about four times during the course of the study, indicating substantial growth of colonies in addition to active budding in polygyne colonies of the red imported fire ant.


Results demonstrate that P. tricuspis and P. litoralis are highly specific to saevissima complex fire ants and strongly indicate that they would pose little threat to native fire ants should they be released as biocontrol agents for imported fire ants in the United States.

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 diverse

Distribution and density of polygyne fire ants (Hymenoptera: Formicidae) in Texas.

The high frequency of polygyny in Texas indicates that the fire ant problem in the state is much greater than previously realized.
