Argentine ant - Wikipedia. The Argentine ant, Linepithema humile (formerly Iridomyrmex humilis), is an ant native to northern Argentina, Uruguay, Paraguay, Bolivia and southern Brazil. It is an invasive species that has been established in many Mediterranean climate areas. These ants will set up quarters in the ground, in cracks in concrete walls, in spaces between boards and timbers, even among belongings in human dwellings. In natural areas, they generally nest shallowly in loose leaf litter or beneath small stones, due to their poor ability to dig deeper nests. However, if a deeper nesting ant species abandons their nest, Argentine ant colonies will readily take over the space. Mayr identified the first specimens of Hypoclinea humilis in the vicinity of Buenos Aires, Argentina in 1. This species was shortly transferred to the genus Iridomyrmex, and finally to Linepithema in the early 1. The Argentine Ant is often confused with a related ant species, the Pharaoh Ant (Monomorium pharaonis). The three colonies in question were one in Europe, stretching 6,0. Mediterranean coast, the . In their introduced range, their genetic makeup is so uniform that individuals from one nest can mingle in a neighboring nest without being attacked. Thus, in most of their introduced range, they form supercolonies. This type of social organization is not only a key attribute responsible for the ecological domination of these ants, but also an evolutionary paradox and a potential problem for kin selection theory because relatedness between nest mates is effectively zero. In 1. 99. 7, UC San Diego researchers observed fighting between different Argentine ants kept in lab, and in 2. San Diego. On the border of the Very Large Colony and the Lake Hodges Colony thirty million ants die each year on a battlefront that covers miles. Argentine ants in their native South America also co- exist with many other species of ants, and do not attain the high population densities that characterize introduced populations. The hydrocarbons from the diet were eventually incorporated into the cuticle of the subjects. Those that had the same diet appeared to recognize one another as kin. Those who had at least some overlap in dietary composition also appeared to react non- aggressively to one another. These interactions contrasts drastically with the groups that fed on completely different sources, such as those who lived off flies and those that fed on grasshoppers.

The groups appeared to have incorporated hydrocarbons that were not similar to the others and created an unfamiliar identity cue. These groups reacted violently towards each other. This suggests that dietary factors affect the recognition cues for colony members. The queens seldom or never disperse in winged form. Instead, colonies reproduce by budding off into new units. As few as ten workers and a single queen can establish a new colony. Eggs are produced in late- winter, nearly all of which hatch into sexual forms by May. Mating occurs after the females emerge. Worker production increases steadily from mid- March to October, after which their numbers are not replenished; thus, their numbers drop steadily over the winter months. As the colonies expand, they appear to form fluctuating territory borders, which contract and expand on a seasonal and conditional basis. There is an expansive push outward in the summer months, with a retreating motion in the winter. This has to do with soil moisture and temperature conditions. This can, in turn, imperil other species in the ecosystem, such as native plants that depend on native ants for seed dispersal, or lizards that depend on native ants for food. For example, the recent severe decline in coastal horned lizards in southern California is closely tied to Argentine ants displacing native ant species on which the lizards feed. Thus, when Argentine ants invade an agricultural area, the population densities of these plant parasites increase and so does the damage they cause to crops. When they invade a kitchen, it is not uncommon to see two or three queens foraging along with the workers. Eliminating a single queen does not stop the colony's ability to breed. Spraying with pesticides has occasionally stimulated increased egg- laying by the queens, compounding the problem. Pest control usually requires exploiting their omnivorous dietary habits, through use of slow- acting poison bait (e. It may take four to five days to eradicate a colony in this manner. They made a compound that is different, but similar, to the one that coats the ants. If the chemical is applied to an ant, the other members of the colony will kill it.
