Abstract:

Abstract As a alien invasive species, golden apple snail has caused great harm to agricultural production in Guangdong Province. The density of snails was investigated after winter time for three habitats (paddy field, dry land, drainage and irrigation channels) in six regions including Shantou City, Shaoguan City, Zhaoqing City, Zengcheng City, Maoming City and Zhanjiang City, Guangdong province to see differences among different land use types and different regions. The results showed that the density of apple snail were significantly different in three kinds of habitats with an change order: drainage and irrigation channels>paddy fields>dry lands. Density of apple snails had some significant differences among paddy fields and drainage and irrigation channels of different regions, Overall, the density of apple snails changed with an order of Shantou
