Objective To know whether the imported Oncomelania snails could survive in a simulated environment. Methods Snails from Guichi, Anhui province were put into the ponds of 4 square meters on each with densities of 25, 50, 100, 200, 400 and 800 pairs. In the next 2 years, the activities of the snails and their offspring snails were recorded by some person every day. Statistical methods were used for this experiment. Results The Total No. snails declined on soil surface among the two years. Wilcoxon W Test and Kruskal - Wallis test were used to analyze total No. snails and No. filial generation snails on different densities respectively, results showed that there were statistical significances on total No. snails and No. filial generation snails except 12.5 snails per square and 100 snails per square groups. The statistical formula on total No. snails to different densities in 2011 and 2012 were Y=19.08Inx-21.66 (R2=0.217, P < 0.01) and Y= 6.31Inx-6.09 (R2=0.299, P < 0.01). On 2011 and 2012, the statistical formula on No. filial generation snails to different densities were Y=0.05Inx+0.14 (R2=0.002, P > 0.05) and Y=0.39Inx-0.13 (R2=0.041, P < 0.01). Conclusion The oncomelania snails can survive in the soils in neighborhood province. But there wasn't any snail establishment in the two years.
