The golden apple snail (GAS, Pomacea canaliculata), an invasive freshwater gastropod from Argentina causing a series of problems in rice production, in the environment, and in the spread of parasitic diseases, has been successfully introduced to and as colonized Asia, North America, and some other South America countries. In the People's Republic of China (PRC), this snail was first introduced to Guangdong in the 1980s to be raised for food. Its range was expanded in short order until it reached its northerly limit near 30 deg north latitude. This limitation might change due to the striking adaptability of GAS to various environments. It can borrow deeply for hibernation and it can modify its diet to include local plants. Consequently, much effort to decrease the population or even eradicate the species has been expended in infested countries. However, no commonly accepted control strategy has been found. Research results of studies in the PRC in recent years are briefly discussed, most of which have concerned the biological features and ecological characteristics of GAS, local strategies for control, and other aspects leading to the potential establishment of a more comprehensive strategy.
