Although a disease of great antiquity, scientific studies of schistosomiasis began only 150 years ago. The complete life-cycle was not described until just before the First World War, making it possible at last to plan proper community control programmes. Inadequate tools prevented their effective implementation until well after the Second World War when new tools became available, thanks to th...

Reports of snails’ resistance to niclosamide appeared recently and finding new molluscicides becomes necessary. We investigated the molluscicidal effects Cucurbita maxima seed extracts on Biomph...

the effect of annona squamosa, lawsonia inermis and their combination with other herbal molluscicides were studied on different enzyme activity in the nervous tissue of lymnaea acuminata. twenty-four hour in vivo exposure to 40% and 80% of 24 h lc50 of plant derived molluscicides and their combination with other molluscicides such as cedrus deodara, azadirachta indica oil, allium sativum, polia...

A total of 1,426 species of plants had been tested in order to find out a vegetal-derived molluscicide against the vectors of Schistosoma mansoni. Euphorbia splendens is one of the most promising molluscicides. In this article we briefly present the main aspects that have to be considered to use this plant as a molluscicide, which include some agricultural aspects and operational methods for ap...

The effect of sub-lethal doses (40% and 80% of LC(50)/24h) of plant derived molluscicides of singly, binary (1:1) and tertiary (1:1:1) combinations of the Rutin, Ellagic acid, Betulin and taraxerol with J. gossypifolia latex, leaf and stem bark powder extracts and their active component on the reproduction of freshwater snail Lymnaea acuminata have been studied. It was observed that the J. goss...

methanol extracts of callistemon viminalis (sol. ex gaertner) g.don ex loudon fruits, bark and leaves were tested for molluscicidal activity. snails were collected and kept in dechlorinated water under standard condition. ten adults b. alexandrina, of the same size, were introduced in plastic acquaria for each experiment. the powdered organs extracted with methanol and the dried extracts were k...

in vivo and in vitro sublethal exposure of abrin, glycyrrhizin (active component of abrus precatorius seed and root), sanguinarine, protopine (argemone mexicana seed) and oleandrin (nerium indicum leaf) inhibited the acetylcholinesterase, lactic dehydrogenase, acid and alkaline phosphatase activity in the nervous tissue of lymnaea acuminata. the succinic dehydrogenase activity in the nervous ti...
