In this thesis, we investigated (1) the relative role of climate and biotic factors varying with climate in the selection of local adaptations of drosophila parasitoids (2) how the phenotypic plasticity of life history traits has evolved in reponse to the environment and egg maturation strategies of these organisms. Contrarily to the primary consumers in which evolution of life histories is directly affected by temperature, biotic factors varying with climate, such as host distribution and interspecific competition may be the principal agent of natural selection in parasitoids. Host distribution may explain the very strong variations that we observed, such as the existence of proovigenic and synovigenic populations in a same species and pop...
