IMPORTED FTRE ANT: HISTORY, IMPACT AM1 MANAGEMENT
David F. Williams
USDA-ARS, Center for Medical, Agricultural, and Veterinary Entomology
1600/1700 SW 23d Drive
Gainesville, FL 32608
HISTORY
The red imported h ant, Solenopsis invicta Buren, was probably introduced in the port of
Mobile, AL around 1930's. The first collections were obtained in Mobile and the 1''
identification was made as S. saksima var. richteri in 1930. In 1930, the infestation was
limited to the Mobile area. The red imported fire ant continued to spread by means of mating
flights, the movement of colonies and newly mated queens on flood waters, movement of
nursery stock, bee hives, constcuction equipment, railroad cars and open truck beds. In 1949, a
survey found 14 Mississippi, 12 Alabama and 2 Florida counties infested and then in 1 953, a
four year survey by the USDA showed that this ant had spread to 102 counties in I 0 states. The
increased mge of the red imported fire ant is now over 32 1 million acres in southern U.S. and
Puerto Rico. The principal areas of expansion include Oklahoma, Arkansas, Tennessee, Texas,
North Caroba nd Virginia with recent infestations occuning in California, New Mexico, and
Arizona.
WACT
The impact of S. invicta is extensive and occurs on human health, crops, livestock, wildlife,
biodiversity, utilities, recreation, tourism, transportation (roadways), and envir0mmt.l quality.
The most noticeable problem caused by fire ants is stinging of humam which in some cases
cause serious injuries and can even result in death. S. invictca is also responsible for damage to
farm products such as soybeans, okra, potatoes, corn, and young citrus trees. It also impacts on
the nursery industry because of the federal quarantine requirement that all nursery stock and
grass sod moving out of the fie ant infested areas be treated with approved insecticides. In
addition, S invicta is a threat to domestic animals causing economic losses to farmers and can
cause an overall reduction in biodiversity in many areas. The overall impact from S. invicta
infestations across the southern U.S. is over $1 billion dollars annually.
MANAGEPvfENT
There are several reasons why S. invicta are dificult to control. For example, they have large
populations, produce large numbers of reproductives, lack natural enemies, have little
competition, are very aggressive and sting, and thrive in a wide range of habitats. During the
World War IT years (1940-1947) dl control programs for S. dnvicta were haIted and this ant
continued to spread. In 1948, Mississippi, Alabama, & Louisiana appropriated funds for control
programs using 5 % chlordane dust. In 1 957, the U.S. Congress appropriated $2.4 million to
USDA to initiate a federaVstate cooperative control and eradication program. In November,
I 95 7, heptachlor and dieldrin were applied by air and ground equipment and within one year,
environmental concern began because of high mortality seen in birds. During the 1960'~m~ir ex
bait was developed by the USDA-ARS and in 1962, mirex bait replaced heptachlor as the
treatment for S. invicta. Mirex was applied h m 1 962-1 978 using converted World War II
aircraftovermore than 140million acres. Totaltreatmentcost was30 centsper acrewhich
~
includedthebait andapplication. Inthelate 1960's,mirexresidueswere detected innontarget
organismsand allregistrations ofmirexwere cancelledin 1978. Theother reasons for -
cancellationwere persistence inthe environment, accumulationin nontarget organisms,toxicity
to estuarineorganisms anditspotential asacarcinogen. Followingthe banof mirex,political
pressure onCongress forfindingareplacementwas intense,thus, Congress appropriated funds
forthe USDA-ARSto begin anintensified searchfornew chemicals foruse in fire antbaits. ....
This allowedan increasein thenumber ofchemicalsevaluatedforS. invicta baits by USDA-
ARS. During 1958-1976(18years),2,678chemicalswereevaluated,however, from 1977-1988
(11years),4,432 productswere tested. Thehistorical developmentof chemicals forfire ant ....

Baits forS.invicta consists ofthe followingcomponents,(1)attractants(oils, sugars,proteins,

Thepresent control ofS. invictaconsistsmainly ofusingchemicals. The chemical control
