Mode d'Introduction: Notes sur l'espèce pour cette localité:
In March 2005 samples collected from Kreer Heights, Wewak, were confirmed to be the little fire ant (Wasmannia auropunctata). The source of the infestation was believed to be an orchid plant obtained in Bougainville in 1999. The results of a survey indicate that the little fire ant prefers foraging on tree trunks in shaded areas especially on banana trees. The infestation is thought to affect six hectares of land covering residential zones and vacant land. Notes sur la gestion de l'espèce dans cette localité:
Results of a bait preference experiment suggest the ant prefers protein (egg solids) to carbohydrates (jam) or lipids (butter).
The travel of people and the movement of produce and furniture are likely to result in spread of the ant to new localities, suggesting the best way to prevent spread of the ant is to increase general public awareness of the ant in the region. It is hoped that the small population currently established at Kreer Heights can be eradicated using Xtinguish baits and 6-monthly surveillance for two years following bait applications to detect any re-infestations in the area. The existance of other infestations is likely and the extent of the distribution of the little fire ant in Papau New Guinea is still unknown. Impacts:
Nuisance pour les personnes: The ants over-run gardens and homes in residents' houses and sting people, especially children. Control of insect pests within houses is expensive and many families may be forced to live with the ant. Dernière mise à jour: 20/06/2006 12:29:56 p.m.
