Abstract
The survival of the freshwater snail species Bulinus africanus, Bulinus globosus and Biomphalaria pfeifferi at extreme high temperatures was experimentally investigated. Snails were exposed to temperatures in the range from 34°C to 40°C and their survival was noted daily. The results showed that the survival of the cohorts of all three species decreased with increased temperatures. It was also found that B. globosus survived longer at high temperatures than B. africanus and B. pfeifferi. There was no marked difference between the survival of the latter two species.Keywords
