Invasion of Polygyne Fire Ants Decimates Native Ants and Disrupts Arthropod Community

  author={Sanford D. Porter and Dolores A. Savignano},
The fire ant Solenopsis invicta Buren invaded southeastern United States from South America >50 yr ago. Urban and agricultural consequences of this invasion are well documented; however, ecological effects are still poorly understood. Increasing frequencies of polygyne or multiple—queen fire ants in Texas and other areas of the Southeast are disturbing because nest densities of this new form are often ten times as great as those of the more familiar monogyne form. We studied the ecological…

Intraguild Predation of Beneficial Arthropods by Red Imported Fire Ants in Cotton

It is suggested that red imported fire ants are major intraguild predators of important beneficial arthropods in cotton.

Ecological dominance of the red imported fire ant, Solenopsis invicta, in its native range

It is revealed that the red imported fire ant ecologically dominated other terrestrial ants in its native range; however, other species were able to be numerically dominant or co-dominant in its presence.

Mechanisms of Competitive Displacement of Native Ant Fauna by Invading Myrmica rubra (Hymenoptera: Formicidae) Populations

Results indicate competitive superiority by M. rubra with respect to native ant communities of the northeastern North America and suggest direct aggression and competitive exclusion at food resources can lead to local native displacement.

Biodiversity of Fungi in Red Imported Fire Ant (Hymenoptera: Formicidae) Mounds

It is suggested that differences between fungal communities in soil from native and non-native ant colonies might indirectly influence ant-mediated seed dispersal by affecting seedling survival.

Experimental evidence that the introduced fire ant, Solenopsis invicta, does not competitively suppress co-occurring ants in a disturbed habitat.

The results are contrary to classical predictions and indicate that S. invicta is not a superior competitor that suppresses native ants, and that the low diversity and abundance of native ants in degraded ecosystems does not result from interaction with fire ants.

Consequences of Forest Clear-Cuts for Native and Nonindigenous Ants (Hymenoptera: Formicidae)

This study is the first to document, through a controlled experiment, that clear-cutting alters ant species assemblages by increasing S. invicta and Pheidole spp.

Area-wide suppression of invasive fire ant Solenopsis spp. populations.

The fire ants Solenopsis invicta Buren and Solenopsis richteri Forel were inadvertently introduced into the USA early in the 1900s and currently inhabit over 150 million hectares in Puerto Rico and

Biogeographic effects of red fire ant invasion

The results suggest that the effects of S. invicta on native ant communities are pervasive: not only does the presence of the red imported fire ant reduce species density at local scales, it alters the co-occurrence patterns of surviving species at a biogeographic scale.

Abundance and Distribution of the Invasive Ant, Solenopsis invicta (Hymenoptera: Formicidae), in Cypress Savannas of North Carolina

Cypress savannas join a growing list of habitats, having wet sandy or loamy soils and little canopy, that have become invaded by S. invicta in the absence of anthropogenic soil disturbances and could have important direct and indirect effects on the native communities.



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

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.

Recolonization by ants of rehabilitated mineral sand mines on North Stradbroke Island, Queensland, with particular reference to seed removal

The ant fauna of 12 sand-mined plots representing a range of rehabilitation ages and three undisturbed vegetation controls was surveyed during 1982 and indicates that the previous ant-seed relationship had been partially restored by this time, although the relative contribution of seed harvesters and elaiosome collectors still needs to be assessed.


In a survey conducted in the Southeastern United States, one colony in a sample of 1,007 colonies of the red imported fire ant, Solenopsis invicta Buren, was infected with a microsporidium (Protozoa:

Failure of the Red Imported Fire Ant to Reduce Entomophagous Insect and Spider Abundance in a Cotton Agroecosystem

Large numbers of the red imported fire ant, Solenopsis invicta Buren, were unable to pauperize the predator arthropod fauna of a cotton field in east Texas, suggesting that it is a fairly specialized predator though probably a polyphagous scavenger.

Patterns in the Red Imported Fire Ant Settlement of a Louisiana Pasture: Some Demographic Parameters, Interspecific Competition and Food Sharing

In a densely populated pasture near Hammond, La., Solenopsis Invicta Buren mounds have an aggregate distribution with an average mound density of 0.0096/m, and Monomorium workers appeared to possess a powerful poison which, when spread in the air, had a strong repellent effect against S. invicta workers.

Arthropod Populations in Permanent Pastures Treated and Untreated With Mirex for Red Imported Fire Ant Control

Experiments were conducted in 1972–73 to study interrelationships between red imported fire ants, Solenopsis invicta Buren, and associated arthropods in pastures, where predation of immature horn flies was intense, associated rove beetles also were apparently preyed upon.

Foraging Activity of Ants (Hymenoptera: Formicidae) in a Pasture Inhabited by the Red Imported Fire Ant

Ant species were found to have localized population distributions that overlap slightly and S. invicta and Lasius neoniger (Emery) were the most abundant and frequently collected species of ants.


An electrophoretic study of the genetics of three fire ant species in North America was undertaken, finding that the native fire ant, S. geminata, is genetically the most distinct of the three species studied, in accord with its taxonomic placement in a different species complex.

The Displacement of Native Ant Species by the Introduced Argentine Ant Iridomyrmex Humilis Mayr

Not only does I. humilis displace’ native ant species, but it has been shown to displace other introduced tramp species.
