The Argentine ant (Linepithema humile, formerly Iridomyrmex humilis) is an ant native to northern Argentina, Uruguay, Paraguay, Bolivia and southern Brazil. [1]
The latter is better known as the Argentine ant, an invasive species with notable presence in Mediterranean climates. Linepithema species are found from sea level and up to 4,000 meters above sea level in the Andes. [3]
The Argentine ant (Linepithema humile), forming megacolonies of spatially separate nests, was thought to be a perfect example of unicoloniality, never exhibiting multicoloniality. [ 8 ] Giraud et al. (2002), however, discovered that L. humile also forms supercolonies that are aggressive to each other, so unicoloniality turned out to be limited.
Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant (Linepithema humile), the erratic ant, the odorous house ant, and the cone ant.The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and ...
The colony was estimated to contain 306 million worker ants and one million queen ants living in 45,000 nests interconnected by underground passages over an area of 2.7 km 2 (670 acres). [14] In 2000, an enormous supercolony of Argentine ants was found in Southern Europe (report published in 2002). [15]
For an Argentine ant colony to successfully wipe out a monogyne colony of 160,000 workers, the colony would need 396,800 workers. A colony that has reduced in size due to successful bait treatment are prone to predation by Argentine ants. The ants may play a vital role in removing weakened fire ant colonies, and they may also be important in ...
