Abstract
Controlling of Biomphalaria alexandrina snails by plant molluscicides is the cornerstone in treating schistosomiasis in Egypt. The objective of this study is, to evaluate the molluscicidal activity of the aqueous leaves extract of Anagallis arvensis against B. alexandrina snails. The present results showed that this aqueous extract was lethal for B. alexandrina snails at (LC50 37.9 mg/l; LC90 48.3 mg/l), and caused reduction in survival; reproductive rates and hormonal activity (testosterone (T) and 17β-estradiol (E)) of these snails. Histopathological changes occurred in the hermaphrodite glands of snails exposed to the sub lethal concentrations of this aqueous extract are detected, where, there were degeneration in both eggs and sperms and there were losses of connective tissues between acini. The present investigation revealed that this plant had a genotoxic effect especially with its concentration (LC10 and LC25), where, the length of olive tail moment was significantly increased than control group. These observations prove the potent molluscicidal activity of aqueous leaves extract of A. arvensis against the intermediate hosts of Schistosoma mansoni and provide natural biodegradable resources for snails’ molluscicidal agents. © 2018 Elsevier Inc.
