Abstract:
Objective To explore the aestivation and lethal hyperthermy temperature of Oncomelania hupensis in summer,which is one of important ecology indexes,in order to understand the potential impact of global warming on the distribution of Oncomelania snail in mainland China. Methods Oncomelania hupensis hupensis snails were collected from the marshland region in Jiangsu Province and the aestivation and lethal hyperthermy temperature were examined by increasing temperature gradually in laboratory. Results The lethal hyperthermy temperatures of 50% Oncomelamia snails in dry and wet environment was 40.01℃ ( 95% of confidence interval from 39.76-40.27℃) and 42.13℃( 95% of confidence interval from 41.59-42.68℃), respectively. The logistic regression equations between temperature and mortality were d=101/(1+e 61.402269-1.535058X) (F=69.997,P
