Argentine fire ants have spread around the world from a population that was first established a century ago in North America. The fire ant Solenopsis invicta is a significant pest that was inadvertently introduced into the southern United States almost a century ago and more recently into California and other regions of the world. An assessment of genetic variation at a diverse set of molecular markers in 2144 fire ant colonies from 75 geographic sites worldwide revealed that at least nine… 

Exotic spread of Solenopsis invicta Buren (Hymenoptera: Formicidae) beyond North America

This more recent exotic spread of the South America fire ant S. invicta beyond North America is examined, reporting new West Indian records and questioning some Asian records.

Global invasion history of the tropical fire ant: a stowaway on the first global trade routes

Genetic data are used to trace the global invasion of one of the world's most widespread and invasive pest ants, the tropical fire ant, Solenopsis geminata, revealing a pattern of introduction of Old World populations that is highly consistent with historical trading routes suggesting that Spanish trade introduced the tropicalFire ant to Asia in the 16th century.

First record of the red imported fire ant, Solenopsis invicta Buren, from Hispaniola

The red imported fire ant, Solenopsis invicta Buren, is one of the most damaging pest species in the world. A native to the floodplains of subtropical South America, it has been spread to North

The Ecological and Population Genetic Consequences of Invasion by the European Fire Ant, Myrmica rubra, in Ontario

It is shown that M. rubra disperses seeds further from its nests than a native “keystone” seed-dispersing ant, which resulted in a long-term influence of ant species identity on plant survival, spatial arrangement, and community composition.

Invasion and high-elevation acclimation of the red imported fire ant (Formicidae: Solenopsis invicta) in the southern Blue Ridge escarpment region

There was no significant difference in colony lipid content along the gradient, suggesting that greater metabolic rates are not needed to sustain these ants through winter dormancy at high elevations, and nest-site selection in proximity to a thermal mass does not seem to improve thermoregulation.

Population Genetic and Social Structure Survey of Solenopsis geminata in Thailand.

This survey of fire ant specimens in Thailand found that all colonies were polygynous with only a few queens, which suggests that queens were locally mated and founded colonies by a budding strategy.

Unusual chromosome numbers and polyploidy in invasive fire ant populations

Fire ants from invaded populations differed in chromosome morphology compared to those from native populations; the Florida and Taiwanese fire ant populations evinced greater variability in chromosome numbers and polyploidy variations; and the Taiwanese population exhibited significantly increased Ag-NOR signals in interphase cells.

Invasion and high-elevation acclimation of the red imported fire ant, Solenopsis invicta, in the southern Blue Ridge Escarpment region of North America

Investigating potential physiological adaptations of S. invicta found that occurring at higher elevations exhibited greater physiological tolerance for cold temperatures as compared to lower-elevation conspecifics–a cold tolerance pattern that paralleled of the native A. picea ants along the same gradient.

Red Imported Fire Ant Solenopsis invicta Buren

Since it was found in Taiwan and mainland, the spread of red imported fire ant Solenopsis invicta Buren into China has been continuous. In order to achieve better control of this pest, science and

Fire Ants (Solenopsis spp.) and Their Natural Enemies in Southern South America

It is concluded that the objectives of the ARS program in South America are being achieved and that the pioneering studies have served to encourage further investigations in the United States and other countries and advanced the implementation of biological control programs to decrease imported fire ant densities and damage.



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.

Putative native source of the invasive fire ant Solenopsis invicta in the USA

This attempt to identify the source(s) of the red imported fire ant (Solenopsis invicta) in the southern USA utilizing data from three classes of genetic markers and employing Bayesian clustering simulations, assignment and exclusion tests, and phylogenetic and population genetic analyses concludes that the Mesopotamia flood plain near Formosa, Argentina represents the most probable source region.

Population genetics and history of the introduced fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), in Australia

It is found that both Australian infestations were more similar to North American populations than to South American, though the Fisherman Islands infestation was intermediate, making it difficult to assign.

Population Genetics of the Invasive Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the United States

Bayesian analyses showed that study populations most distant from the claimed site of entry, Mobile, AL, have diverged most from the hypothetical founder population, consistent with an invasion scenario in which the ants spread outward from Mobile through repeated subfounder events.

Bridgehead Effect in the Worldwide Invasion of the Biocontrol Harlequin Ladybird

It is shown that the recent burst of worldwide invasions of HA followed a bridgehead scenario, in which an invasive population in eastern North America acted as the source of the colonists that invaded the European, South American and African continents, with some admixture with a biocontrol strain in Europe.

Population genetic structure of the red imported fire ant, Solenopsis invicta, in Taiwan

This is the first study to investigate the population and colony structure of fire ants in Taiwan and results represent an important contribution to the ongoing efforts aimed at eradicating this invasive pest.

Multiple Transatlantic Introductions of the Western Corn Rootworm

It is demonstrated that there have been at least three independent introductions from North America during the past two decades, which raises questions about changing circumstances that have enabled a sudden burst of transatlantic introductions.

Genetic variation increases during biological invasion by a Cuban lizard

It is shown that one key to invasion success may be the occurrence of multiple introductions that transform among- population variation in native ranges to within-population variation in introduced areas.

The importance of transport hubs in stepping‐stone invasions

Busy transport hubs should be considered a priority for the allocation of preventative and management efforts, such as regular baseline or target surveys and the development of incursion response plans that minimize the risk of spread within the transport network.

The Fire Ants

The reader learns much about ants, the practice of science, and humans' role in the fire ant's North American success.
