✦ Synopsis
Biological control of the intermediate hosts of schistosomiasis by means of the introduction of a competitor snail Helisorna duryi has been suggested . In the present laboratory studies the allometric size-weight relationships of H. duryi and Biomphalaria camerunensis were investigated in order to get a tool for estimating the biomass and dry-weight of snails .
Competition experiments were conducted and the results showed a marked inhibition of growth and reproduction of B. camerunensis. No conclusions about the competitive interactions were drawn from the present results but experiments are established to elucidate these mechanisms .
