Resumo: Growth curves and mortality rates for populations of Biomphalaria glabrata and B. straminea bred under semi-natural conditions are reponed. Snail populations of the above species were maintained for 220 weeks in indoor cement channels. Data were recorded at 20 week intervals. Crude densities are significantly different for each of the studied populations. B. glabrata showed the lower figure while B. straminea R3 strain showed the best performance. The latter is able to live in half the volume of water needed for B. glabrata when both are submitted to population pressure.

As populações dos caramujos foram observadas durante 220 semanas em canaletas de cimento montadas no laboratório. Dados foram coletados a cada intervalo de 20 semanas. As densidades brutas de crescimento foram significantemente diferentes para cada população estudada. B. glabrata mostrou crescimento inferior às duas cepas de B. straminea. A cepa R3 desta última espécie mostrou o melhor desempenho, sendo capaz de viver em metade do volume de água necessária a B. glabrata quando ambas estão submetidas a pressão populacional.Reports in Public HealthCadernos de Saúde Pública1992-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/354Reports in Public Health; Vol. 8 No. 2 (1992): April/JuneCadernos de Saúde Pública; v. 8 n. 2 (1992): Abril/Junho1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/354/707https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/354/708Barbosa, Frederico S.Sanches, OdécioBarbosa, Constança S.Arruda, Franciscoinfo:eu-repo/semantics/openAccess2024-03-06T15:25:48Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/354Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:00:32.769903Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
