//&#;&#;The overwhelming majority of all allergic reactions to fire ants in the United States are caused by the red imported fire ant, Solenopsis invicta. However, there are four additional species of fire ants found in North and Central America, as well as the Caribbean and Pacific islands, Allergic reactions to the venoms of all of these species have been reported.


//&#;&#;This leads us to a chemical reaction that is worth talking about. As it turns out, as unpleasant as the venom of the fire ants is, they meet their match in another species of ant, the tawny crazy ant. These two warring species of ants both make use of their venoms in conflict, but the tawny crazy ant uses chemistry to gain a clear advantage.

It is a highly significant inverse relationship, Platts-Mills says.


//&#;&#;Less common types of fire ants include Solenopsis geminata ,Solenopsis xyloni, Solenopsis aurea and Solenopsis richteri. These types of fire ants are considered native fire ants and although not as common, they can still leave behind painful bite marks. Many fire ants are identified by their geographic locations.


Two species of fire ants are found in Florida.

Other distinguishing features include a -segmented pedicel and an unarmed propodeum When sting-ing, the fire ant pinches the skin with its mandibles and arches its back to inject venom. Unlike the stinger of a bee ...

Background: There are four species of fire ants found in the found in Texas, the southwestern United Stares, Cal- Unlted States in addition to the most common, Solenopsis ifornia, and Mexico.

Other Ants A varity of other species have been implicated in allergic reactions, but are much less common than the ones described above. These include the Imported Fire Ant around Brisbane, and a number of smaller ants (similar in size to the Greenhead Ant).


Fire ants have been studied thoroughly and are considered responsible for most of allergic reactions secondary to ants in the United States. Systemic reactions with fire ant stings occur in about of exposed individuals, and more than fatalities have been reported from fire ant-induced anaphylaxis. In China and Korea another species of ant known as Bachycondayla chinensis is a ...


//&#;&#;Background: There are four species of fire ants found in the United States in addition to the most common, Solenopsis invicta. Reactions have been reported from stings of each of these species, but large numbers of insects and adequate amounts of venom for study are very difficult to obtain. Methods: Venom was obtained, the purified allergens were isolated, and the complete amino acid ...


//&#;&#;Usual Reactions . Usual (typical) reactions occur in essentially % of people stung by IFAs and include localized pain, swelling, and redness at the site of the sting.Within hours, a pus-filled blister will develop at the site of the sting.

//&#;&#;The purpose of this study is to explore the nature of reactions to various species of fire ants and to investigate whether there might be clinical, immunologic, and structural cross-reactivity among the venom allergens. It was not possible to obtain large numbers of insects to prepare venom from any of the native species.
