Notes sur l'espèce pour cette localité:

Notes sur la gestion de l'espèce dans cette localité:
The collection and killing of snails is the only local control measure. Most people use salt to kill the snails by dehydration; a popular method is to pack snails in plastic bags and throw them onto roads to be crushed by passing traffic. People living by rivers and irrigation canals throw their daily collections directly into flowing water. The Byans Municipality of Tanahun district initiated an official eradication program of A. fulica in 1993 with the help of public participation by providing 20 Nepalese Rupees per 10 kg incentive to local people. The municipality dumped more than 5.5 metric tones of collected snails on the bank of the Madi river. This practice was followed for a number of years but has since been abandoned and A. fulica continues to be abundant in the area.
Agricole: Achatina fulica is a serious pest of vegetables and considered to be a major problem in kitchen home gardens by District Agriculture Officers in many districts where they occur. Many farmers have complained that they could not grow nursery-raised vegetables by transplanting them into the fields because they are immediately eaten by A. fulica. They can completely wipe out vegetable crops such as cauliflower, potato, cabbage, pumpkin, cucumber, bottle gourd, white gourd, spinach, radish and tomato. Cereals such as hyacinth bean, cow pea, black gram, maize and millet, and fruits such as banana, guava, papaya, and jack fruit are all considered to be vulnerable. One of the respondents in Mirmi told us that one day they destroyed 500 recently transplanted cauliflower and cabbage plants within just one night (Budha & Naggs 2008).
Nuisance pour les personnes: The snail is reported to leave sticky slime trails and excreta wherever it goes, including on vegetable leaves and the walls of houses. The density of rotting snails can impart an offensive odour along extensive lengths of road.
