Biology, life-tables, and intrinsic rates of increase of Bulinus globosus Morelet and Lymnea natalensis Kraus (Gastropoda: Pulmonata)--the snail intermediate hosts of Schistosoma haematobium and Fasciola gigantica, respectively, in Southeastern Nigeria.

Two tables and a figure are used to present the epidemiological and epizoological particulars of Bulinus globosus and Lymnaea natalensis, the intermediate hosts of Schistosoma haematobium and Fasciola gigantica in Southeastern Nigeria. Possible ways of reducing the populations of these intermediate hosts are seen in the combined application of chemical agents and environmental shaping.
