The little re ant, Wasmannia auropunctata, is a small ant native to Central and South America, which has been introduced into a third of the Pacic region's island groups. It is considered by invasive experts to be the greatest ant species threat within the Pacic islands region.
Although its ocial discovery in Tahiti was in 2004, it is likely that the little re ant has been present in Tahiti for much longer. The centre of contamination in Tahiti is the northern Mahina Commune. Initial treatment and monitoring initiatives to combat the ant invasion were carried out between 2005 and 2009, but were discontinued in 2010.
