Effect and Machanism of Sapium sebiferum Against Snail (Oncomelania hupensis) and Control of Schistosomiasis

Abstract

Potential allelopathic or toxic effect of some plant species can be useful for controlling snail acting as intermediate host of schistosomes. We reported on the toxic activity of extract from Sapium sebiferum against snails transmitting Schistosoma japonicum. Aqueous extract, ethanol extract, acetic ether extract or benzene extract from leaves, branches, roots and seeds of Sapium sebiferum have toxic effect on snail host. Benzene fraction from fresh leaves and deciduous leaves can also kill snail at different mortality. Benzene fraction of fresh leaves decreased head protein content, liver protein content and glycogen of snails submerged at different concentrations and different days. We concluded that Sapium sebiferum is an effective molluscicidal plant species.
