“…The present investigation showed that exposure of B. alexandrina snails to LC25 of Bestacid E. C. insecticide for two weeks, gradually decreased their survival rate and highly decreased their reproductive rate (RO) than the control ones and by studying the histopathological changes, it caused a complete destruction of gametogenic cells and severe damage in hermaphrodite gland tissues. These findings agree with that recorded by Abdel-Ghaffar et al (2016) who reported that, survival rate of B. alexandrina snails, the reproductive (R0) and fecundity rates were reduced after their exposure to the sub lethal concentrations of Butralin 48% EC, glyphosate isopropylammonium 48% SL and Pendimethalin 50% EC herbicides. They reasoned this reduction by histological examinations, which showed severe damage in the digestive and hermaphrodite gland cells of the treated snails.…”

“…There are several strategies have been used to control snail populations through breaking the life cycle (El-Ghany and El-Ghany, 2017). Manufactured molluscicides is an imperative part in the incorporated schistosomiasis control programs (Abdel-Ghaffar et al, 2016), but due to they have high cost and being poisonous to creatures of land and water (WHO, 2014), have stimulated interest to find suitable plant molluscicides (Elsareh et al, 2016).…”

Keywords: B.alexandrina Anagalis arvensisCopper oxide Molluscicide Nanoparticles Histopathology Nanotechnology has received more attention in the field of control of intermediate hosts. In the present study, copper nanoparticles were fabricated and characterized using scanning electron microscopy (SEM), transmission electron microscope (TEM), x-ray fluorescence (XRF) and fourier transform infrared (FTIR). Improvement of the molluscicidal activity of Anagalis arvensis ethanolic extract was made using CuO NPs by forming plant nanocomposite (ACuO NC). The results showed that ACuO NC has high molluscicidal activity against B. alexandrina snails; recording LC 50 and LC 90 were 1.76 and 3.16 ppm, respectively. Also, biochemical parameters (Total protein, ALT, AST and ALP) revealed highly significant changes in treated snails with sublethal concentrations (LC 10 and LC 25 ) of ACuO NC. However, histopathological changes occurred in the hermaphrodite glands of snails exposed to these concentrations of nanocomposite were detected, where, the ova and sperms degenerated and there were losses of connective tissues between acini. ACuO NC was more safety when tested against the biological indicator Daphnia magna. These observations prove that ACuO NC has potent molluscicidal activity against the intermediate hosts of Schistosoma mansoni with more safety for aquatic environment.

Aim:The present study aims to focus on the role of common marine snails (Littorina littorea) as a vector for some trematode parasites.Materials and Methods:A total of 327 marine water L. littorea snails were collected during the summer of 2016 from a Qarun lake in the EL-Fayoum Governorate, Egypt. The snails were investigated for infection by trematode parthenitae through induction of cercarial shedding by exposure to light and crushing the snails. The species were stored in Search Laboratory of Zoology Department, Faculty of Science, Fayoum University.Results:Three species of Strigeid littorina cercaria were identified from the infected snails. They are described here and they identified in relation to close-up morphological features and linked to its snail hosts. They give the following names: Cercaria strigeid littorina type 1, C. strigeid littorina type 2, and C. strigeid littorina type 3. The incidence of infection by these cercariae was 33%, 25.7%, and 2.4%, respectively.Conclusion:This study is clarifying the importance of this marine snail as intermediate hosts for new trematode species.
