Thymol as Molluscicidal Agent Against Biomphalaria alexandrina, Intermediate Host of Schistosoma mansoni

Molluscicidal activity of sodium hypochlorite against Biomphlaria alexandrina snails: Immunological and hepato-endocrine alterations with in silico docking study

“…Similarly, Beltagi et al, 2010 reported a significant increase in the levels of ALT and AST in the exposed land snails to LC25 and LC50 thymol. On contrary, ( Abdel Salam et al, 2022 ) found that thymol could inhibit the release of ALT and AST in the hemolymph of exposed snails. According to the effectiveness of molluscicides as a toxic agent that induced rupturing and inflicted injuries in many snail organs, may explain the changes in the activities of AST and ALT exposed B. alexandrina snails ( Ahmed et al, 2012 ).…”

Molluscicidal and Larvicidal Potency of N-Heterocylic Analogs against Biomophalaria alexandrina Snails and Schistosoma mansoni Larval Stages

“…They suggested that reduction was due to disturbance in egg-laying enzyme (phenol oxidase). Abdel Salam et al [56] proved that sub-lethal concentration of thymol (plant molluscicide) for 4 weeks showed an oviposition inhibitory activity and reproduction rate against B. alexandrina snails.…”

“…Concerning the effect of sub-lethal concentrations of CAAQ on the hatchability of B. alexandrina eggs, the tested compound caused no hatchability when compared to the control snails. Many investigators proved a relationship between metabolic disorders of exposed snails to different plant molluscicides and the size and viability of their egg masses [55,56]. Hamdi and Rawi [57] showed the effect of Agave filifera and A. attenenuate plants (family: Agavaceae) on B. alexandrina snails, causing inhibition of egg production, a significant increase in the abnormality percentage of eggs and a decrease in their hatchability of the same batch of eggs.…”
