Abstract:
Objective To understand the molluscicidal effects of Eomecon Chionantha Alkaloids (ECA) on Oncomelania hupensis.Methods By using immersion methods for different durations of time the molluscicidal effects of ECA and the rate of snails climbing-upward were observed. Results While the solution concentrations and temperatures of ECA were at 1.25 mg/L,30℃;2.5 mg/L,25℃;5 mg/L and 10 mg/L,25℃ respectively,and the snails were immersed for 72 hours,the mortality of Oncomelania snails were 100%. The hatching rates of Oncomelania eggs after immersed for 72 h in the solution of 5 mg/L were 0～10%. ECA showed an inhibiting effect on the snails' climbing-upward in the concentrations of 5 mg/L. Conclusion ECA has molluscicidal effect on Oncomelania and is one of the potential plant molluscicides.
