Disease control programme managers are becoming increasingly aware of the need to Promote community participation in all aspects of interventions. In the present paper, community participation in snail control is discussed from three standpoints: feasibility, effectiveness as well as long-term sustainability, based on field experience in Zimbabwe, Tanzania and Morocco. The process leading to the involvement of the community appears to be a crucial factor in the success of any community based approach to control snails. In the successful experiences of environmental control of intermediate hosts, the community is mobilized at the design stage and not only at implementation and evaluation. The authors stress the relevance of ecological studies in providing information on environmental factors to be modified in order to make the habitat hostile to the snail hosts.

This research report discusses ecological aspects of schistosomiasis transmission and options for its control in irrigated areas in Africa through environmental measures. Human schistosomiasis is endemic in 46 African countries.After being infected by larvae emerging from human excreta and urine deposited in the water, freshwater snails act as intermediate hosts.

Bulinus truncatus, the intermediate host of Schistosoma haematobium, is widely distributed in modern irrigation schemes in Morocco. These schemes have intermittent irrigation and canals dry out in between irrigation periods. The snail species is therefore associated with the ‘siphon boxes’ connecting canal segments, as these contain water that stagnates between irrigation cycles. The micro-distribution of snails in siphon boxes, was studied before and after one irrigation period, to identify factors that could be manipulated in order to control this snail species. Density of B. truncatus, Ancylus fluviatilis, Lymnaea peregra and Melanopsis praemorsa varied significantly with water depth before and after irrigation. The pulmonate snail species had the highest densities at depths ranging between 20 and 80 cm. After an irrigation period of 10 to 12 hours B. truncatus, A. fluviatilis and L. peregra were relatively more abundant at the bottom of the siphon boxes than in the upper sections. Aggregation at the corners of the boxes could be among the factors that enable snail species to avoid the detrimental effect of turbulent water flow during irrigation. The relevance of changes in density and micro-distribution following an irrigation cycle in the control of B. truncatus is discussed.
