	Red imported fire ant - Wikipedia, the free encyclopedia
		The Red Imported Fire Ant (Solenopsis invicta), or simply fire ant, is one of the 266 species of stinging ant in the widespread genus Solenopsis.
		Although the Red Imported Fire Ant is native to South America, it is best known in the United States, Australia, Taiwan, and the southern Chinese province of Guangdong.
		Solenopsis daguerri (Santschi), a parasitic ant, invades RIFA colonies to replace the queen in hopes of gaining control of the colony.

	Chemical Ecology In The Red Imported Fire Ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae)
		When several workers of Solenopsis saevissima are crushed between two pieces of clean glass and held one to three centimeters above resting workers, these workers exhibit increased excitement and tend to cluster beneath the crushed bodies and lift their gastors in a defensive posture.
		Bigley and Vinson (1975) isolated a brood recognition pheromone and determined it to be a triglyceride lipid compound, triolein.
		Solenopsis invicta venom is primarily (> 95%) composed of piperidine alkaloids (2-alkyl or alkenyl 6-methyl piperidines).

		Solenopsis invicta are aggressive generalist foragers that occur in high densities, and can thus dominate most potential food sources.
		invicta constructs earthen mounds for the purposes of brood thermoregulation, which are easier to build in open, sunny areas; so it is less abundant in, and in general poses a smaller threat to, densely wooded forest habitats (Tschinkel 1993; Porter and Tschinkel 1993, in Morrison et al 2004).

		Technical Abstract: The red imported fire ant, Solenopsis invicta Buren, is an invasive pest from South America that currently occupies much of the southeastern U.S. Global warming is likely to allow range expansion of many invasive species, including S. invicta.
		As the pace of global warming is expected to quicken in the latter half of the century, however, the habitable area for S. invicta in 2100 is predicted to be >21% greater than it is currently (a northward expansion of 133 ± 68 km).

		Technical Abstract: As with most social insects, the red imported fire ant, Solenopsis invicta, utilizes a complex milieu of chemical signals to regulate the activities of the colony.
		Several functions of the alarm pheromone have been suggested for S. invicta, from signaling the presence of a threat, to inducing worker activity during mating flights, as well as attracting eavesdropping parasitoids.
		Wilson demonstrated that frenzied behavior was elicited by exposing S. invicta workers to volatiles released from crushed heads of conspecifics.

		However, by the 1950s, it became obvious that the ant was rapidly expanding its range accompanied with an increase in RIFA density and a decrease in the density of other ants in the areas where it occurred.
		William Buren described the RIFA with the specific epithet name invicta meaning invincible because of its resilient nature and the belief that it would be difficult to manage.

		Solenopsis mounds were disturbed and aspirators were used to collect female phorids when they attempted to parasitize exposed worker ants.
		If the female did begin to attack S. invicta within 20 minutes, the attack rate was recorded over a 5 minute period, beginning with the first attack, and then the female was immediately transferred into a flight box of S. geminata.
		Total time spent with S. invicta (after the first attack) on the initial exposure for all 20 P. obtusus females considered collectively was 129.2 minutes, in which time 111 attacks occurred, for an overall attack rate of 0.86 attacks per minute.

	Invicta Overview
		While basing on Apache ANT, Invicta is not just an ANT extension; it should be generic enough to support in the future build tools other than ANT, and it is used by developers for processing their project's definition files and generating build scripts accordingly.
		Invicta's extensibility also allows accessing the information processed from the project definition files for writing output files other than ANT build.xml (for example, configuration files for a specific IDE).
		In order to make Invicta a useful Open-Source project that developers can easily extend and maybe contribute to its development, Invicta must be a modular extensible framework.

		We sequenced a portion of the wsp gene from the Wolbachia genome infecting 138 individuals from eleven geographically distributed native populations of the fire ant Solenopsis invicta.
		invicta presumably would have to be quite ancient, since it requires that the infection would have had to be present in the common ancestor of clades II-V (see Figure 1).
		invicta may be due to: 1) presence of different Wolbachia variants within and among populations 2) genetic differences among host individuals from different populations or 3) genetic drift [48].
