【摘要】：目的了解曼氏血吸虫的中间宿主藁杆双脐螺的生态水力学特性。方法采用排水体积法和沉降管法分别测定了双脐螺的密度和静水沉速。结果藁杆双脐螺的密度在1.04~1.16 g/cm~3之间,平均密度为1.08 g/cm3;其静水沉速在2.32~12.92 cm/s之间。结论藁杆双脐螺的生态水力学特性与钉螺有所不同,在研究采用水利措施防控藁杆双脐螺扩散中应考虑其特性。
[Abstract]:Objective to investigate the ecological and hydraulic characteristics of Schistosoma mansoni, an intermediate host of Schistosoma mansoni. Methods the density and hydrostatic sedimentation velocity of snail were measured by drainage volume method and sedimentation tube method respectively. Results the density of Gaolius bicusphora was 1.04 ~ 1.16 g/cm~3, the average density was 1.08 g / cm ~ (-3), and the hydrostatic sedimentation rate was between 2.32 and 12.92 cm/s. Conclusion the ecological and hydraulic characteristics of Biomonas mandarinensis are different from those of Oncomelania hupensis, and its characteristics should be considered in the study on the prevention and control of the diffusion of the snail by using water conservancy measures.
