Solenopsis invicta, the fire ant, or red imported fire ant (RIFA), is a species of ant native to South America. A member of the genus Solenopsis in the subfamily Myrmicinae, it was described by Swiss entomologist Felix Santschi as a variant of S. saevissima in 1916. Its current specific name invicta was given to the ant in 1972 as a separate ...
In the 1930s, colonies were accidentally introduced into the United States through the seaport of Mobile, Alabama.Despite earlier views that cargo ships from Brazil docking at Mobile unloaded goods infested with the ants, [1] recent DNA research confirmed that the likely source population for all invasive S. invicta in the United States occurred at or near Formosa, Argentina, and virtually ...
Solenopsis geminata is native to Central and South America, including the Caribbean islands, but has since spread throughout the tropics by human means. It is an invasive species with a world-wide distribution even greater than that of other invasive fire ant species such as Solenopsis invicta (red imported fire ant).
Pseudacteon tricuspis was the first species of Pseudacteon fly successfully used as a biological control agent for the imported red fire ant in the US. [2] Imported red fire ant Solenopsis invicta was accidentally introduced into the United States in Alabama in the 1930s. Since then, its populated area has expanded across the country, including ...
Fire ant queens may live up to seven years and can produce up to 1,600 eggs per day, and colonies will have as many as 250,000 workers. [12] [18] The estimated potential life span is around 5 years and 10 months to 6 years and 9 months. [19] Young, virgin fire ant queens have wings (as do male fire ants), but they often cut them off after mating.
The southern fire ant (Solenopsis xyloni), also known as the Californian fire ant or cotton ant, [1]: 89 is a stinging fire ant native to southern parts of the United States. [ 2 ] [ 3 ] [ 4 ] Its behaviour is similar to the red imported fire ant (S. invicta) , although its sting is less painful.
The little fire ant (Wasmannia auropunctata), also known as the electric ant, is a small (approx 1.5 mm (1 ⁄ 16 in) long), light to golden brown (ginger) social ant native to Central and South America, now spread to parts of Africa (including Gabon and Cameroon), Taiwan, [2] North America, Puerto Rico, [3] Israel, [4] [5] Cuba, St. Croix and six Pacific Island groups (including the ...
