Abstract:
Objective To understand the eco-hydraulics characteristics of Biomphalaria straminea,the intermediate host of Schistosoma mansoni. Methods The drainage method and settlement tube method were applied to measure B. straminea's den-sity and hydrostatic settling velocity respectively. Results The density of B. straminea was 1.04-1.16 g/cm3,and the average value was 1.08 g/cm3. The hydrostatic settling velocity was 2.32-12.92 cm/s. Conclusions The eco-hydraulics characteristics of B. straminea is different from Oncomelania hupensis,and more attention should be paid to the hydraulic measures for the con-trol of B. straminea.
