title: [Hematophagous diptera arbovirus vectors in Africa (author's transl)].
abstract: The authors, in a first part, show the general arthropods-viruses-vertebrates relationships and specially the different conditions of virus maintenance in the selvatic foci. Then they succinctly give the main characteristics of the vectors bioecology useful for understanding the epidemiology of arbovirus diseases of man and domestic animals. Thus diptera vectors of o'nyong-nyong and chikungunya fevers, yellow fever, dengue fever, Wesselsbron, Sindbis, and West Nile viruses, Rift Valley fever, sandfly fevers, bluetongue and african horsesickness are recorded. Lastly some attention is given to the range of virus-vector specificity and to the virulence variability of virus according to the vector.
