    Details of this species in New Caledonia (Nouvelle Calédonie)
    Status: Alien
    Invasiveness: Invasive
    Occurrence: Established
    Source: Gargominy et al. 1996
    Arrival Date: 1972
    Introduction: Unintentional (accidentally)
    Species Notes for this Location:
    A. fulica was accidentally introduced in 1972, probably with ornamental plants from Tahiti (Gargominy et al. 1996).
    Management Notes for this Location:
    Attempted control methods include biological controls (Euglandina rosea, Gonaxis quadrilateralis and G. kibweziensis), physical and chemical protection methods, educational programmes, the planting of resistant yam varieties and the application of salt, ash, oil or water in ditches around crops (J. Manaute pers. comm., in Cooling 2005).

    Biological control: Two species of predatory snails, the rosy wolfsnail (Euglandina rosea) (originating in Central America) and Gonaxis quadrilateralis (originating in East Africa), were introduced intentionally from Guam in 1974. Euglandina established locally but is not invasive, but Gonaxis did not acclimatise (Gargominy & Bouchet, 1996, in Gargominy et al . 1996).

    Physical Control: In 1976 a ten day campaign was run in which snails were collected around Noumea on a large scale involving members of the public, who were paid for snails collected. Approximately 800 000 snails were collected. While these efforts did not eradicate the species it was sufficient to relieve the pressure on native species (CTRDP de Nouvelle Caledonie Undated).
