title: [Phlebotomus of the Congolese Mayombé (Diptera, Psychodidae). Phenologic study].
abstract: The seasonal cycle of activities of three phlebotomine sandflies populations of the congolese Mayombe proves to be closely linked to climatic factors. The entire population of the so-called "Faustin" tropical rain forest consist of a cycle of abundance which reaches two very pronounced peaks during the periods of heaviest rainfall each fall. The forest-skirt species at Dimonika are most active when the rains begin anew. The seasonal population cycle at Makaba in 1978, on other hand, was severely disrupted following a period of exceptional drought at the beginning of the year. Abundance and frequency are assessed and seasonal fluctuations analyzed for each species.
