Fig 2: The molluscicidal activity of ethanol extracts of pumpkin seeds on Biomphalaria and Bulinus snails over a three-day period.
The results also showed that there was no significant difference between the effects of the water and ethanol extracts on adult Biomphalaria (p = 0.875; CI=95%) as is also shown by the  mortalities of   the snails  in  the  graph given below (Fig 3).
