AMERICAN ENTOMOLOGIST • Fall 2001 The major ant pest in the southern United States in the early 1900s was the Argentine ant Linepithema humile (Mayr) (Wojcik 1994). Thus, there was little concern when imported fire ants were detected in and around Mobile, AL, by Loding (1929). In a short time, this level of concern changed as this new, more serious pest became a major problem. At the time of its discovery, this new pest was believed to be only one species, Solenopsis saevissima (variety… 


Fire ant populations in their South American homeland are about 1/5 to 1/10 as dense as populations in North America, with escape from numerous natural enemies left behind in South America the most apparent explanation for the intercontinental population differences.

Response of Wasmannia auropunctata (Hymenoptera: Formicidae) to Water-Soaked Imported Fire Ant Baits

Abstract The little fire ant, Wasmannia auropunctata (Roger) (Hymenoptera: Formicidae), is a stinging invasive ant that can establish extremely large, dominating populations in tropical 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.

Effect of Irrigation on the Control of Red Imported Fire Ants (Hymenoptera: Formicidae) by Water-Resistant and Standard Fire Ant Baits

Abstract The red imported fire ant, Solenopsis invicta (Buren), is an invasive pest of agricultural, urban, and natural areas. It is also considered a public health pest due to its painful stings.

Occurrence of Phorid Fly (Diptera: Phoridae) Parasitoids of Imported Fire Ants (Hymenoptera: Formicidae) in Georgia

Results show that all 159 counties in Georgia have at least 1 species of Pseudacteon; P. curvatus and P. tricuspis occur together in 39 counties, and all 3 of the PseudACTeon species occur in the 1 county in which all 3 species were released.


Two imported fire ants (IFA), the red imported fire ant (RIFA), Solenopsis invicta, and the black imported fire ant (BIFA), S. richteri, were introduced into the United States in the early 1900's and

Trail Pheromone Disruption of Red Imported Fire Ant

Results show that trailing fire ants become disorientated in the presence of large amounts of Z,E-α-farnesene, and disrupting fire ant recruitment to resources may have a negative effect on colony size or other effects yet to be determined.

Fire Ant Control with Entomopathogens in the USA

Research on fire ant-specific microsporidia and viruses, as well as other fire ant entomopathogens, is summarized to illustrate the efforts that have been undertaken to understand the biology of these pathogens and to facilitate their utilization in biological control of fire ants.

Solenopsis invicta (red imported fire ant).

Abstract S. invicta is an ant native to South America. It is an aggressive generalist forager that occurs in high densities and can thus dominate most potential food sources. It breeds and spreads

The effects of hydramethylnon on the tropical fire ant, Solenopsis geminata (Hymenoptera: Formicidae), and non-target arthropods on Spit Island, Midway Atoll, Hawaii

It is concluded that Maxforce® can be used to control small infestations of S. geminata and T. bicarinatum effectively; however it is recommended to be used cautiously due to the potential ecological cost to non-target species.



Biology and control of imported fire ants.

The purpose here is to review this research, although because of space limitations, much of the recent work concerning the chemical toxicology and persistence of mirex, the chemical currently used for control of imported fire ants.

Use of fenoxycarb for area-wide management of red imported fire ants (hymenoptera: formicidae)

Large-scale field testing of 1% fenoxycarb bait (Logic), an insect growth regulator, was conducted in Kendall and Kerr counties, Texas, to determine efficacy in controlling red imported fire ants, Solenopsis invicta Buren, and it is concluded that one application of Logic is highly effective in suppressing populations of S. Invicta.


It is now clear that forms morphologically identical with the "light" and "intermediate" phases of the Gulf States population occur commonly in the zone of intergradation between Solenopsis s.

Invasion and Range Expansion of Imported Fire Ants (Hymenoptera: Formicidae) in North America from 1918-1995

A native of South America, imported fire ants were first detected in this country in Mobile, AL around 1918 and had expanded its range to include a total of 114,098,722 ha in all or part of 670 counties/parishes in 11 states and Puerto Rico in 1995.

Red imported fire ants (Hymenoptera: Formicidae): frequency of sting attacks on residents of Sumter County, Georgia.

A survey of the human sting attack rate of the red imported fire ant on a sample population in Sumter Co., Georgia, USA, was conducted over a 12-month period, with the number of stings declined with increased age.

Fire Ants and Their Management.

(Buren), is an introduced species that arrived in Mobile, Alabama from South America around the 1920s. This species has had an enormous impact in the southeastern United States, and continues to

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.


The results of the field tests indicate that teflubenzuron has excellent potential for control of field populations of S. invicta and the presence of worker brood in the plots treated with the lower rates gave evidence of recovery of some colonies.

Effectiveness of Fenoxycarb for Control of Red Imported Fire Ants (Hymenoptera: Formicidae)

The insect growth regulator fenoxycarb reduced colony size indices of laboratory colonies of red imported fire ants, Solenopsis invicta Buren, by 93-98% within 8 wk after treatment. Reductions were

Imported Fire Ants: Eradication Trials with Mirex Bait12

These were the first fullscale attempts to totally eliminate ants from given areas and offer the 1st proof that queens can disperse up to 12 miles during nuptial flights.
