A study has been made of the effect of Alarisa cornuanetis
on 4 populations of Biomphalaria alexandrina, exactly matching control populations in size, number and season of nurture. The observations were made
in a series ofartijicial earth-lined ditches with continuously flowing Nile water.
Q]ıantitative estimation of the densities of the experimental and control populations was made by standard twice a month samplings with a dip net.
Signijicant reductions in density of the experimental populations, as compared to the control populations, were observed. The results suggest that Marisa
cornnuarietis could be of great value as a biological control agent against natural
populations of Biomphalaria alexandrina in Egypt.
