摘要：

Between 1987 and 1990, snail surveys were carried out in the Senegal River Basin at Lampsar, in a natural 'marigot', and at Richard Toll, in an irrigation canal. Lymnaea natalensis, Bulinus guernei* and B. forskalii, were regularly found at both the sites. Bulinus globosus/jousseaumei and B. umbilicatus were only present at Lampsar. A decrease of the snail density was observed during the rainy season at Lampsar. The recent appearance of Biomphalaria pfeifferi at Richard Toll is discussed. The data show that adult B. pfeifferi are present in the main irrigation canal all through the year. Consequently parasite transmission will be possible throughout the year as well.
