Long-term controlled field experiment on the competition between two species of Biomphalaria (Mollusca, Basommatophora), the snail vectors of Schistosoma mansoni in Northeastern Brazil


, : Long-term controlled field experiment on the competition between two species of Biomphalaria (Mollusca, Basommatophora), the snail vectors of Schistosoma mansoni in Northeastern Brazil. Cadernos de Saude Publica 9(2): 170-176

A long-term controlled field experiment on the interactions of the populations of Biomphalaria glabrata (target population) and B. straminea (competitor) was carried out in the county of Alhandra, Paraiba, Brazil. B. straminea R3 strain (resistant to Schistosoma mansoni) was introduced into 11 streams between 1980 and 1989. B. straminea had strong competitive advantages over B. glabrata.
