Toxicological investigation and anti-reproductive effect of phyto-molluscicide against harmful aquatic snail

Saroj Chauhan, Ajay Singh


In this study attempt was made by using active component Taraxerol isolated from medicinal plant of India, Codiaeum variegatum (Family: Euphorbiaceae) to control harmful disease schistosomiasis in domestic animals caused by harmful aquatic snail Indoplanorbis exustus in laboratory as well as in experimental pond by acute and chronic analysis. This snail acts as intermediate hosts for the digenetic trematodes parasites which infect them and therefore causes reduced livestock productivity, morbidity and mortality. In this study time as well dose dependent effect of Taraxerol was observed in laboratory as well as in pond. Toxicological investigation shows difference in the toxicity between both the conditions, as toxicity in pond was lowered than laboratory. Chronic analysis of sub-lethal concentration of this compound was also studied on the reproductive traits of snail in laboratory and it was found that Taraxerol has negative effect on the fecundity, hatchability and survivability of juveniles and hence have potential to control such harmful disease.
