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]
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 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.
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 ...
The reasons that can lead ant colonies to clash are varied and depend on the species, locations, and contexts. For a number of them, such as leafcutter ants Atta laevigata, wood ants of the genus Formica, certain species of the genus Carebara, or giant ants Dinomyrmex gigas, it is a matter of territory covered and thus the available food for the different colonies.
The final research topic for Gordon and her team is the spread of the invasive Argentine ant. 1996, Gordon published her most cited article, "Exploitation and interference competition between the invasive Argentine ant, Linepithema humile, and native ant species."
Linepithema humile virus-1 (LHUV-1) was found to be introduced by Argentine ants into New Zealand and Australia. Aside from the ants, the virus has also been reported in other species worldwide such as honeybees. Argentine ants host and act as a reservoir of Deformed wing virus (DWV), which is an agent implicated of honeybee deaths. A ...
