|Abstract:||The attraction exercised over Schistosoma mansoni miracidia by Biomphalaria straminea, Lymnaea columella and Physa sp using a specially designed apparatus consisting of two circular glass chambers joined by an open channel were studied. The molluscs or their snail-conditioned water (SCW) was placed in one of the chambers (randomly chosen). In the channel ten miracidia was deposited and the count of miracidia in each of the three compartments (the two chambers and the channel) was recorded during fifteen minutes. Ten replications of each experiment with different specimens of molluscs and miracidia were made. Statistical and ad-hoc exploratory data analysis showed that: a) the three species of molluscs and their SCW attract the miracidia; b) Physa sp attract more miracidia then L. columella. There was an isolated single B. straminea specimen that had a repulsive effect to the miracidia.|
