[The control of Aedes (Stegomyia) and related species involved in transmission of human arbovirus infections in tropical Africa (author's transl)]. / Le côntrole des Aedes (Stegomyia) et espèces voisines vecteurs d'arboviroses humaines, en Afrique tropicale.

ABSTRACT

In Africa, many Aedes mosquitos are involved in yellow fever and dengue transmission. Their control can be carried out either in a "prophylactic" way, when no disease occurs, or in a "curative" one, when virus is detected in the human community. In the first event, control is confounded with sanitation measures; in the second event, insecticidal control is needed against both larvae and adults. Larvae populations are destroyed by means of insecticidal deposits in the breeding-sites. Control of adults is achieved by thermal fogs or U.L.V. applications of organophosphorous compounds dispensed from ground or aerial generators. The insecticide susceptibility level of every Aedes populations involved in arbovirus transmission must be periodically determined with all the insecticides available.
