Effect of sublethal concentrations of Atriplex halimus (Chenopediaceae) on Biomphalaria alexandrina, the snail-vector of Schistosoma mansoni in Egypt.
Effect of sublethal concentrations of Atriplex halimus on the mortality rate, longevity, egg production of Biomphalaria alexandrina and hatchability of their eggs were studied. The sublethal concentrations of Atriplex caused reduction in survival rates, longevity and egg production of B. alexandrina. Hatchability of snail eggs exposed to tested plant was decreased by increasing its concentrations.
