Notes sur la gestion de l'espèce dans cette localité:
In 1957 the predatory rosy wolfsnail (Euglandina rosea) was introduced into Guam to control A. fulica. Non-target impacts included the consumption of native snails (Hoddle 2004). The predatory flatworm Platydermus manokwari may have been responsible for a 95% decrease in achatinid populations in Guam over 4 years. Impacts:
Agricole: Irrespective of crop the seedling or nursery stage is the most preferred stage and the most vulnerable. In some situations infestations of crops in the seedling stage are so severe as to demand changes in the crop species cultivated. In Guam, Indonesia and Malaysia, for example, A. fulica infestations made it uneconomic to grow vegetables, at least during the period of peak infestations (South 1926, Kondo 1950a, Mead 1961, in Raut & Barker 2002). Thus production of some crops has proved unsustainable in certain infested areas. Dernière mise à jour: 9/03/2010 3:52:00 p.m.
