      Equipe:    Pheromones, food, chemoreception and sexual selection (PACS)   


Time shared on two themes of research

– The first theme concerns the study of the drosophila male and female interactions (under group melanogaster)  during the coupling according to the evolution of the morphology of sperm cell and male seminal substances (with D. Joly).

– The second theme concerns the study of the reproductive isolation in the drosophila in connection with the evolution of pheromones (with C. Wicker-Thomas).
