The giant African snail, Lissachatina fulica (Bowdich, 1822) in China: current status, threats and management

Due to their rapid growth and ability to establish feral populations, non-native species pose a significant threat to global biodiversity and ecosystem functions. Terrestrial molluscs are particularly problematic among non-native invertebrates, damaging agriculture and forestry. The giant African snail (Lissachatina fulica), native to Africa, has been introduced worldwide, except Antarctica. Unintentionally introduced in China about a century ago, it has become a major agricultural pest in South China. However, limited biological and ecological information hampers control or eradication efforts. Our study, based on field surveys and literature review, summarises its introduction pathways, current distribution, and ecological and economic impacts in China, providing up-to-date information and management recommendations for better control of this species.
