The survival rate of B. alexandrina snails maintained in aqueous solutions of the two tested plants (Calendula micrantha and Anagallis arvensis) decreased gradually with time until the 9th week and 10th week where the survival rate was zero in the high concentration of A. arvensis and C. micrantha, respectively, meanwhile, the survival rate of the control was 20%. Also, the two plants caused reduction in hatchability of snails egg masses. Thus, the percent of hatching in A. arvensis (82 ppm) was 46% and in C. micrantha was 72% compared with control (97.29%). Both plants reduced the infection rate of Biomphalaria alexandrina snails with Schistosoma mansoni miracidia to 41.17% and 61.9%, respectively, compared with control (90%). C. micrantha caused much higher reduction in snail infection rate than A. arvensis. The prepatent period was significantly prolonged in snails maintained at higher concentration of both plants. The cercarial output (expressed as mean number/snail) revealed that, A. arevensis caused a significant reduction in cercarial production than control. While, high concentration (120 ppm) of C. micrantha caused a significant elevation in the mean number of cercariae/snail. However, the total number of cercariae produced by all snails in each group showed a reverse relation with the tested concentrations in both plants.
