[Ecology of the ceratopogonids of the Alsace plain. III. Life-cycle of the Culicoides (Diptera, Ceratopogonidae) from a fluvial breeding-place (author's transl)].

In the East of France, Culicoides clastrieri, C. odibilis, C. cubitalis, C. subfascipennis and C. musilator have 2 generations per year; a spring generation and a summer generation. A part of the summer population undergoes a aestivo-hibernation which is terminated around december. The possibility of a winter diapausa is evocated.
