Giant African Snail (GAS) is one of the world's largest and most damaging land snail pests.The Global Invasive Species Database has included this snail among the “100 World's Worst” invaders. It is nonhost specific and can consume at least 500 different types of plants, including breadfruit, cassava, cocoa, papaya, peanut and most varieties of beans, peas, cucumber and melon. The snail is native to coastal East Africa (Kenya and Tanzania), but is now widespread on all continents except Antarctica. It is highly adaptive to a wide range of environmental conditions and is capable of modifying its life cycle to suit local conditions. GAS is a threat to the sustainability of crop systems and native ecosystems, has a negative impact on native fauna, and acts as a vector of human diseases.
