Abstract:
Objective To evaluate the efficiency of prevention of Oncomelania snail dispersal with the mode of leading water from middle level of water body by the culvert pipelinet in the electric pumping station. Methods The snails were detected in the floats by riverhead and the irrigation areas, and the snails were hold up by the block in the exit of pump. The snail investigation was carried out in the irrigation system areas and the results were compared between the study area and the control area. Results The snails were discovered in the floats of riverhead of the electric pumping station. However, there were no any snails in the exit of pump after the block snail treatment and no any snails in the irrigation areas, either. There were snails in the control areas Conclusion The mode of leading water from middle level of water body by the culvert pipelinet is very effective for the prevention of Oncomelania snail dispersal.
