Abstract: Some ecological aspects of introduced Achatina fulica Ferussac including breeding period shell dimension, egg-laying number, population structure and distribution are discussed in this paper. Its breeding period in south China is from July to November, the highest percentage of egg-carrying individuals be appeared in July.No significant correlation between shell length and egg-laying number can be found. Under controlled temperature of 25℃, only 59.3% of eggs can develop to larva. Its population is mainly comprised by young snails.Achatina fulica also presents in some other parts of China.
