Geographic Range

Argentine ants (Linepithema humile) are a significant invasive species across the globe. They are native to the Neotropical region, originating in South America; they are notwithstanding widespread across the region. Since the late 1800s, they have been spreading due to human commercial activities, primarily to regions with a Mediterranean climate. They are now institute on all continents except Antarctica and some Oceanic islands. Their range is restricted by temperature; they typically cannot survive in areas with a mean daily temperature below 7 to 14 degrees Celsius. In the United States, Due north Carolina and California are the northern most edges of their range; they are much more common in littoral regions than in the interior of the country. They can be establish across much of Europe, including the Iberian peninsula, France, and of course, the Mediterranean. They are also significant in Nippon, S Africa, New Zealand, and Australia. (Brightwell and Silverman, 2010; Abril, et al., 2008; Aron, et al., 2001; Brightwell and Silverman, 2010; Brightwell, et al., 2010; Inoue, et al., 2013; Lach, 2013; McGrannachan and Lester, 2013)

Habitat

Argentine ants are able to survive in a variety of habitats, limited merely by temperature and h2o sources. They are able to survive in temperatures from -5 to 45 degrees Celsius, though they typically cannot thrive in areas with a mean daily temperature below 7 to 14 degrees Celsius. Water sources are also fundamental to these ants, including natural sources such as rivers and man-made sources such equally urban water runoff. Colonies nest in forests, agricultural fields, shrublands, fields, nearly rivers, and in other areas disturbed by human activity. Nests are also prevalent in urban and suburban areas, as these ants can invade homes and other buildings. Nests are shallow, typically no more than 1 to 2 inches into the soil. Argentine ants also nest under forest and debris, in sandy soil, under rocks, in cracks in pavement, and in buildings. (Enzmann, et al., 2012; Brightwell and Silverman, 2010; Enzmann, et al., 2012; Fitzgerald and Gordon, 2012; Keller, et al., 1989; McGrannachan and Lester, 2013; Rice and Silverman, 2013; "Argentine ant — Linepithema humile", 2009)

Physical Clarification

Argentine ants are a small species of ants, with 1 petiole, a curt, robust thorax, a flattened head, and slender legs. Workers are typically around 0.three mm in length, unlike other emmet species; all workers are the same size. Workers weigh nearly 0.43 mg. Males are almost the same size or a piffling larger than workers, weighing about 1.0 mg, while sexual females (also known as queens) are significantly larger, measuring 4.5 to 5.0 mm in length and weighing about 3.6 mg. All ants of this species are irksome dark-brown, though males and queens are usually darker than workers. Their coloration is uniform across their body, though pocket-sized trunk parts, such every bit mandibles and antennae can have 3 different shades. Workers have yellowish mandibles and their legs are a lighter shade of brownish than their trunk. Sexual females take yellow mandibles and cherry-red legs and antennae, while males take yellow legs, antennae, and mandibles. Sexual females are besides more than opaque than workers, with more hairs on their trunk. Males have wings throughout their adult lifespan, while sexual females lose their wings afterwards mating. (Markin, 1970; Newell and Barber, 1913; Passera and Aron, 1996; "Argentine ant — Linepithema humile", 2009)

Their eggs are pearly white and elliptical in shape. Their hateful size is 0.three mm long by 0.two mm broad and they weigh nearly 0.02 mg. The surface of their eggs becomes dull when they are nearly hatched. Newly hatched larvae are about 0.v mm long and grow to nearly 1.7 mm, though male larvae can grow to 2.5 mm in length. Larvae are white and curved, straightening as they develop and grow. They weigh 0.1 to 0.5 mg. Queen larvae are matte and opaque in advent and tin can be hands distinguished from the shiny larvae of workers and males. Pupae are naked but their features are visible. While three forms can exist differentiated, all are white after pupation and transition through several shades of foam and brown until they achieve a similar shade as adult ants. Worker pupae are near ii.0 mm long, with a prominent caput that is about 50% of their length and noticeably visible eyes. Male pupae are about 3.0 mm long, with a big thorax. Queen pupae are much larger than either male or worker pupae, with prominent wing pads and proportionate body parts.

Development

Argentine ants are holometabolous. Eggs are laid from early spring to tardily fall and hatch after about 28 days, though incubation can last from 12 to 55 days. During the showtime 5 days subsequently hatching, larvae grow speedily; their development takes xi to 61 days, with an average of 31 days. Workers pupate for an boilerplate of 20 days, males pupate for 19 to 28 days, and queens pupate for ii to 4 weeks. Development is faster at warmer temperatures. Prior to machismo, their legs, oral fissure parts, and antennae go prominent, workers help remove the pupal skin and straighten the body parts. During this stage, known as the callow stage, newly molted ants await like all other adults except they are colorless and impuissant, staggering around. Afterward 48 to 72 hours, the emmet is a fully functioning developed. At least 33 days are needed to develop into an developed, though 74 days seems average. The outset batch of eggs, typically laid in early spring, develop into the sexual brood, nowadays in the nest past belatedly bound or early on summer. Eggs laid later in the season develop into workers. Gyne and worker production depends on the presence of queens and the pheromones they produce. The worker population peaks in late summer and fall and brood production decreases steadily in late fall. (Aron, et al., 2001; Keller, et al., 1989; Libbrecht, et al., 2011; Newell and Barber, 1913)

Reproduction

Argentine ants mate in the nest during late spring and summer. Prior to mating, males may join in a nuptial flight, though queens remain in the nest. Males may return to their original nest or join a new nest. If males join a foreign nest, they may face up some aggression from workers, though aggression changes throughout the season. If alate females are present in the nest, workers are significantly less aggressive towards strange males. Mating takes identify a few days afterward eclosion. After nearly 6 minutes and after sperm transfer has occurred, a female will bite her male mate, initiating the end of copulation. On rare occasions, the female's bite may actually impale the male. Other males may fight over females and disturb other mating pairs, likely decreasing the corporeality of sperm transferred. Mating pairs can be seen moving to new locations to avoid these disruptive males. Females are just inseminated by i male, though they may mate with several males. Males can inseminate several females, but oftentimes discharge all of their sperm during one insemination. Males dice before long after mating, while queens exercise not lay eggs until the following bound, if they survive until then. Workers are completely sterile and do not mate. Since nuptial flights allow for dispersal and also prevent inbreeding, it is interesting that Argentine ants mate in the nest. Studies have shown that inbreeding does non really occur, since they are a polygynous (multiple queen) species. Different queens produce genetically different offspring, offering options for mating. Argentine ants avoid mating with siblings. Additionally, since males sometimes take flight, they tin go into other strange colonies, or remain in the original nest. (Aron, et al., 2001; Keller and Passera, 1992; Libbrecht, et al., 2011; Passera and Aron, 1996; Passera and Keller, 1994)

• polygynous
• eusocial

Argentine ants are polygynous and have multiple queens in each nest. Later mating, queens remain in the nest and do non lay eggs until the following spring. However, before they lay eggs, ninety% of queens are executed by workers before the reproductive flavor. The executions take place on foraging trails at night, where workers attack the queens like they attack casualty. Workers grab the queens' legs while others attack the trunk, severing the gaster from the thorax. The pieces either remain on the ground, or workers carry them as they would prey. The reasons for the execution are unclear; though it likely frees up food for the brood and may play a role in differentiation of sexual offspring, as the presence of the queens and their pheromones have an outcome. (Abril, et al., 2008; Keller and Passera, 1992; Keller, et al., 1989; Markin, 1970; Newell and Barber, 1913)

Queens that take not been executed lay their starting time batch of eggs in the jump and proceed laying throughout the summertime. Queens store sperm from their first mating for the residual of their lives and typically accept more sperm stored in their spermathecae than they could e'er use during breed production. They can lay up to 50 or 60 eggs per twenty-four hour period, with an average of virtually 20 to 30 eggs. The rate of oviposition is affected by temperature, 28 degrees Celsius is optimal. The oviposition rate is besides affected by the number of queens present in the colony. A colony tin have hundreds of queens. The more queens present, the lower the oviposition rate for each queen. With more queens, worker care per queen probable decreases. Less food is brought to each queen, decreasing their fettle and oviposition rate. Since queens secrete pheromones that attract workers, more queens mean more pheromones, which become muddled and less distinct, attracting fewer workers to any one specific queen. (Abril, et al., 2008; Keller and Passera, 1992; Keller, et al., 1989; Markin, 1970; Newell and Barber, 1913)

Argentine ants provide pregnant brood care to the queens' offspring. Queens themselves provide provisioning in the eggs, only otherwise do not participate in brood intendance. Workers carry off the eggs as soon as they are laid. In laboratory colonies, workers took constant care of the eggs, moving them continuously throughout the day, perhaps to regulate humidity. Eggs are sometimes kept with larvae and pupae and sometimes separated. Eggs that are not tended by workers do not hatch, so their care is clearly important. Larvae are constantly fed food via trophallaxis by workers; the workers regurgitate food and transfer it from mouth to rima oris. Workers also groom larvae and send them. If the nest is in danger, workers option up all breed stages and move them to safer locations. Workers help male pupae remove pupal peel when molting into adulthood, they help other pupae molt past straightening legs and antennae. Brood care extends slightly subsequently reaching adulthood. In the 48 to 72 hours earlier their exoskeleton hardens, in the callow stage, the newly molted ants are unstable and wobbly. Workers still aid them if necessary, or if the nest is in danger, workers even pick up the unconversant ants and motion them. Afterwards their exoskeleton hardens, ants join the colony and brood care stops. Workers besides play a part in determining the developed role of the larvae. Workers underfeed female person larvae through most of the year, which causes them to develop into workers as adults. In the jump, workers feed female larvae more, causing them to develop into queens. This change in feed is triggered by a pheromone produced by the queens.

Behavior

The beliefs of Argentine ants contributes to their success as an invasive species. These ants find food sources much faster than many native species; in experiments, they find nutrient in mazes very speedily. They minimize foraging time by establishing the shortest path to their food. This allows them to deplete food sources before native ant species observe them. Argentine ants are also very ambitious towards ants and other insects that are not members of their colony, and they will defend their territory. They are also aggressive predators, groups of ants assault larger prey; a group of ants concord the prey'south legs, while some other group attacks the casualty's trunk. Unlike many pismire species, workers of this species accept no castes or divisions of labor. All workers contribute in foraging, brood care, and other tasks. Foraging occurs on trails, typically during the day, generally in the forenoon and standing throughout the afternoon. They likewise perform some night activities, such as the queen executions that occur in the spring. New nests are formed by budding, where one or several females leave their habitation nest with a group of workers and establish a new nest. Argentine ants are semi-nomadic, they move nests to more suitable areas if it is necessary, such equally during floods, dry soil, or other disturbances. They may besides relocate nests seasonally, as temperatures fluctuate. While they are typically institute in Mediterranean climates, colonies tin survive in areas with colder winters past nesting in the top few inches of soil or in piles of decaying affair. During cold temperatures, workers are sluggish, foraging stops, development times for eggs and larvae are significantly longer, and the nests is finer hibernating. (Brightwell, et al., 2010; Enzmann, et al., 2012; Keller and Passera, 1992; Markin, 1970; McGrannachan and Lester, 2013; Newell and Barber, 1913; Torres, et al., 2007)

Argentine ants live in colonies. In their native range of South America, these ants form colonies that extend about a meter, to supercolonies that extend for hundreds of meters. In their introduced range, they class gigantic supercolonies of many nests over an area of 1,000 to iv,000 km. There are no behavioral boundaries between ants from all these nests; ants from foreign nests prove no assailment towards other ants of their species. Ants in these supercolonies are all genetically similar. Cooperation between ants over such a large region is one reason why Argentine ants are such a successful invasive species. Researchers take recently discovered that Argentine ants actually form a global supercolony across Europe, N America, Commonwealth of australia, and Nihon. Argentine ants across these colonies share similar genetics, too as similar hydrocarbon profiles on their cuticles. This supercolony likely came about due to transportation by humans. (Inoue, et al., 2013; Torres, et al., 2007)

Habitation Range

Argentine ants form large colonies, with ants freely moving from nest to nest with no aggression or risk. Their dwelling house range is limited only to how far they can travel and the location of their nests, ants probable move between nests separated by several meters, though colonies can extend for thousands of meters. (Passera and Keller, 1994)

Communication and Perception

Since the ability to class behemothic supercolonies is extremely important for the proliferation of Argentine ants, recognizing other colony members is a necessity. Nest mates identify each other by a shared colony odor on the cuticle of their exoskeleton. This aroma is typically made upwards of hydrocarbons. Past identifying nest mates, ants know when to attack and show aggression. Researchers have recently discovered that the hydrocarbon signature of ants in the introduced range is very like between several continents, indicating a global supercolony. When Argentine ants are brought together from different continents, they practise not show aggression towards each other and identify each other as nest mates. Chemicals on the cuticle also indicate when an ant has died. The disappearance of certain chemicals after death alerts other ants in the nest, who collect the dead ants and move them to a waste matter pile. Living ants tin find a expressionless emmet in less than an hr subsequently death. (Abril, et al., 2008; Choe, et al., 2009; Inoue, et al., 2013; Newell and Barber, 1913; Passera, et al., 1995; Reid, et al., 2012; Torres, et al., 2007)

Touch is used to communicate between ants. Workers oftentimes groom each other, keeping the trunk, mandibles, and antennae clean of debris and strange substances. Touch is as well of import in sensing the surround, as Argentine ants often practice not notice objects unless their antennae or other body function comes into contact. This also suggests that their sight is not especially potent, though they tin can detect light. Pheromones are also essential for communication. When foraging for food, Argentine ants lay downward pheromones to create trails that other ants follow. Since pheromones evaporate relatively quickly, foraging ants constantly make u-turns to reinforce trail pheromones. By creating such a strong trail, Argentine ants are able to rapidly recruit big numbers when a nutrient source is establish. Mass recruitment has allowed Argentine ants to vanquish native ants to nutrient sources and deplete them, or overwhelm native ants that take already found food sources. This is ane of the reasons why Argentine ants have been displacing so many native species. Queens produce pheromones to attract workers to provide care and bring nutrient. Some other pheromone also emitted past queens determines gyne brood production. This pheromone causes workers to overfeed or underfeed larvae. When there are many queens, workers underfeed female larvae to produce other workers. Later queens are exterminated in the jump, in that location is less pheromone present, and workers increase the feedings, causing the sexual brood to develop. (Abril, et al., 2008; Choe, et al., 2009; Inoue, et al., 2013; Newell and Barber, 1913; Passera, et al., 1995; Reid, et al., 2012; Torres, et al., 2007)

Food Habits

Argentine ants are omnivorous. These ants casualty on many different insect species. They also eat nectar from flowers and actress floral nectaries, besides as bird's eggs and expressionless arthropods and other carrion. A major component of their diet is honeydew farmed from aphids and scale insects. A colonies diet can modify over time. Newly established colonies tend to eat protein-rich insect prey, while long-established super colonies primarily eat sugar-rich honeydew. This may be because it can take fourth dimension to establish long-term mutualisms with insects that can provide meaning amounts of honeydew. Inside households, Argentine ants also eat any available human food, particularly sweets. Laboratory colonies show some evidence of cannibalism, feeding on their eggs and larvae.

Predation

Argentine ants are highly aggressive towards other ant species and potential predators. They as well use chemicals to defend themselves. They are preyed on by many spider species, including Zodarion cesari in the Mediterranean. Larval antlions of genus Myrmeleon are too known predators. Antlions grab ants that fall into their pitfall traps. Other larger insects, such as cockroaches, as well feed on these ants. Larger animals, such as amphibians and reptiles, including Japanese tree frogs, Hyla japonica, besides equally several bird species, including northern flickers and house sparrows as well prey on Argentine ants. (Buczkowski and Bennett, 2008; Glenn and Holway, 2008; Ito, et al., 2009; Monzo, et al., 2013; Newell and Barber, 1913; Torres, et al., 2007)

  • business firm sparrows (Passer domesticus)

Ecosystem Roles

As one of the most invasive ant species in the earth, Argentine ants have an extensive affect on the ecosystems that they invade. As their range expands into new regions, Argentine ants are continually displacing native ant species and other arthropod populations. Argentine ants out-compete native species because they detect food sources faster, fodder longer, quickly recruit larger numbers to food sources, and function in a big range of habitats. Their ability to form supercolonies too allows cooperation on a large calibration. In displacing native ant species, Argentine ants disrupt many pismire-plant seed dispersal mutualisms, and do not appear to disperse seeds themselves. Argentine ants besides displace pollinators, causing difficulties for native plants. By causing changes in the native arthropod communities, Argentine ants besides have indirect effects on other parts of the customs. Eliminating native arthropod prey may cause a decrease in bird populations and nesting habits, and may even pose a potential threat to baby birds, as large recruitment numbers could hands overwhelm a newly hatched bird. Displacing native species also negatively affects reptile, amphibian, and mammal species. This can be seen in the decreasing population size of coastal horned lizards in California, likely due to Argentine ants out-competing native ant species. Some other invasive ant species, Asian needle ants are actually displacing Argentine ants from their invasive range in the eastern U.s.. (Abril, et al., 2008; Brightwell and Silverman, 2010; Buczkowski and Bennett, 2008; Inoue, et al., 2013; Lach, 2013; McGrannachan and Lester, 2013; Rice and Silverman, 2013; Rodriguez-Cabal, et al., 2012; Suarez and Case, 2002; Suarez, et al., 2005)

Argentine ants form mutualistic relationships with many honeydew-producing insects, such every bit aphids and coccids. The ants tend the insects and eat the honeydew they produce; in commutation they protect these insect populations from predators and parasitoids. Since honeydew is an of import component of their diet, it is incredibly important that Argentine ants class these relationships with insects native to the regions they have invaded. I study found 48 species of scale insects were tended past Argentine ants in one area. By tending and protecting honeydew producers, these ants allow pest populations to flourish, decreasing the fitness of the plants on which the pests alive. These ants take mutualisms with calibration insects, including terrapin scales, Mediterranean blackness scales, California red scales, and Virginia pine scales, many species of aphids including melon aphids and oleander aphids, and mealybugs including obscure mealybugs, grape mealybugs, vine mealybugs, citrus mealybugs, and citrophilus mealybugs. Argentine ants also farm honeydew produced by gall wasp larvae. Phorid flies are parasitoids that lay their eggs on or inside Argentine ants. The larvae eat the ants' tissues, somewhen killing them. Parasitic Wolbachia bacteria are common in native populations of Argentine ants, though interestingly, infections are significantly less common in introduced populations. (Brightwell and Silverman, 2010; Brightwell, et al., 2010; Bristow, 1991; Inouye and Agrawal, 2004; Markin, 1970; Mgocheki and Addison, 2009; Newell and Hairdresser, 1913; Orr and Seike, 1998; Powell and Silverman, 2010; Reuter, et al., 2005)

Economic Importance for Humans: Positive

There are no known positive effects of Argentine ants on humans.

Economic Importance for Humans: Negative

Argentine ants are one of the nigh invasive ant species in the world, having been distributed worldwide by human being activities and travel. They significantly affect crops, man households, and native species in the regions they invade. The invasion of Argentine ants has resulted in a loss of biodiversity, as they consistently out-compete native ant species, causing negative effects on many other animal populations. While non directly damaging crops, their ability to course strong mutualistic relationships with many species of aphids and other honeydew producing insects allow these crop pests to flourish, causing greater damage to crop yields. Argentine ants also cause infrastructure impairment when they invade buildings. In add-on to being a nuisance, in infirmary settings these ants can transfer pathogens such every bit Escherichia coli, Enterococcus, Streptococcus, and Staphylococcus. Researchers have searched for ways to manage and eradicate ant infestations. Due to their large numbers and supercolony structure, it is very difficult to completely remove these ants from any one area. If one nest is removed, ants from other nearby nests will likely re-colonize the area. Pregnant time has been invested in researching the effectiveness of pesticides and baits that can be brought back and distributed throughout the entire colony. Other researchers accept found that removing or re-locating water sources tin assist keep ants out of buildings and homes. Argentine ants are limited by common cold temperatures, but due to global climate alter and warming temperatures, their range could expand even further.

Argentine ants (Linepithema humile) were previously known equally Linepithema humile. A 1913 government publication concerning this invasive ant species reported instances of human infants covered in swarming ants, even causing several infant deaths, but these accounts were not verified and were likely sensationalized, though the ability of Argentine ants to recruit big numbers is well documented. At that place is a massive amount of literature and enquiry available apropos their impact on the ecosystems they invade, the mutualisms they institute, their supercolony structure, the damage they can do to human being populations, and ways to halt their expansion and curb any farther ecosystem disturbances.

Male sperm storage as well occurs, every bit sperm are retained in the male epididymes (in mammals) for a period that tin, in some cases, extend over several weeks or more, just here we apply the term to refer only to sperm storage by females.

suburban

living in residential areas on the outskirts of large cities or towns.

tactile

uses touch to communicate

temperate

that region of the Earth betwixt 23.v degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circumvolve) and betwixt 23.5 degrees South and 60 degrees S (betwixt the Tropic of Capricorn and the Antarctic Circle).

terrestrial

Living on the ground.

territorial

defends an expanse inside the home range, occupied by a unmarried animals or group of animals of the same species and held through overt defense, display, or advertisement

tropical

the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south.

tropical savanna and grassland

A terrestrial biome. Savannas are grasslands with scattered private copse that exercise non form a closed canopy. All-encompassing savannas are plant in parts of subtropical and tropical Africa and Due south America, and in Commonwealth of australia.

savanna

A grassland with scattered copse or scattered clumps of trees, a type of community intermediate between grassland and wood. See likewise Tropical savanna and grassland biome.

temperate grassland

A terrestrial biome plant in temperate latitudes (>23.5° N or S latitude). Vegetation is fabricated up generally of grasses, the pinnacle and species multifariousness of which depend largely on the corporeality of wet bachelor. Fire and grazing are important in the long-term maintenance of grasslands.

urban

living in cities and large towns, landscapes dominated by homo structures and activity.
