Snail Bulinus

Extracts from tamarind fruit pulp have shown molluscicidal activity against Bulinus trancatus snails. This is probably due to the presence of saponins in the fruit (Imbabi and Abu-Al-Futuh, 1992a, cited in (5)). 

The control of the aquatic snails such as Biomphalaria gtabraia and Bulinus trancatus have been frequently studied in European, African and South-American countries. But in China, this endemic disease is caused by the amphibious snail Oncomelania hupensis. To kill this kind of snail, the molluscicides should not only toxic to it, but also have the abilities to prevent it from up-crawling out of the water while the molluscicides take effect.
