The name army ant (or legionary ant or marabunta [1]) is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area.
Like several other invasive ants, such as the red imported fire ant (Solenopsis invicta), the big-headed ant (Pheidole megacephala), the little fire ant (Wasmannia auropunctata), and the Argentine ant (Linepithema humile), the yellow crazy ant is a "tramp ant", a species that easily becomes established and dominant in new habitat due to traits ...
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 ...
Within the invasion zone, ant colonies are large and include many workers and multiple queens. [30] Argentine ants are opportunistic with regard to nesting preferences. Colony nests have been found in the ground, in cracks in concrete walls, in spaces between boards and timbers, even among belongings in human dwellings.
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 ...
Crazy ant, gramang ant, long-legged ant, Maldive ant, yellow crazy ant: Invasive in Australia, Hawaii, and Indian Ocean islands. Anoplophora glabripennis: Insect Asian long-horned beetle, starry sky beetle Invasive in North America, and established and potentially invasive in parts of Europe. Native to East Asia. Aphanomyces astaci: Pseudo-fungus
Pheidole megacephala is a species of ant in the subfamily Myrmicinae. It is commonly known as the big-headed ant in the US and the coastal brown ant in Australia. It is a very successful invasive species and is considered a danger to native ants in Australia [2] and other places. It is regarded as one of the world's worst invasive ant species. [3]
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.
