Abstract

The present study describes the molluscicidal potency of some naturally occurring compounds and their blends against Biomphalaria alexandrina snail, a vector of schistosoma mansoni in Egypt. The role of the synergist, piperynyl butoxide in improving the efficacy of these chemicals was also investigated. The results revealed that thymol exhibited marked potency with LC50 value of 13.92 ppm, followed by anethole and pulegone with LC50 values of 28.16 and 49.93 ppm, respectively. The toxic effect of these chemicals or their blends against the snails was less active than the standard molluscicides. The synergist, piperynyl butoxide enhanced the toxicity of all of the tested chemicals.
