Abstract

The technique of snail surveillance as an ecological approach to snail control is outlined. The method is discussed and results of urine surveys of the past six years in the Kyle catchment show a reduction in the prevalence of S. haematobium. A comparison with parameters calculated by Macdonald (1965) indicate a reduction in the mean worm burden which approaches the theoretical expected when a population is protected by snail control. The costing of snail surveillance operations indicates that on the Rhodesian Highveld the overall annual expenditure is 2.4 pence per acre of land protected.
