- Abstract: Objective To study the effects of environmental temperature and humidity on the survival and reproduction of Oncomelania snails, and to provide a basis for the development of scientific strategies and measures for snails control. Methods Based on the field experimental base of Oncomelania snails in Hubei Province, through long-term and systematic ecological observation of snails, the living conditions of snails at different temperatures were recorded, and the average densities of live snails and young snails as well as the amount of spawning were calculated. Results In a certain temperature range (15°C-30°C), the average densities of live snails and young snails were positively correlated with the changes of temperature and humidity, and the effect of temperature on the spawning of snails was also significant. The optimal breeding temperature of Oncomelania snails was 25°C. Conclusion In a certain temperature range (15°C-30°C), the environmental temperature and humidity have a significant impact on the survival and reproduction of snails in the field.
