[The culicidian fauna and its nuisance in Kinshasha (Zaire)].

A public health study to inventory bloodsucking mosquitoes was conducted in Kinshasa and its regions. 20 culicidian species were represented by 7 Anopheles, 6 Culex, 5 Aedes and 2 Mansonia. In general, the number of bites/man/night (b/m/n) was in average 141.5 of Cx. quinquefasciatus, 60.1 of Cx. antennatus, 21.1 of M. africana, 16.3 of An. gambiae and 7.7 of M. uniformis. The nuisance is different from region to other. Culex quinquefasciatus is the most abundant and aggressive species in the urban area with an average of 400 b/m/n. In certain suburban zones, Culex antennatus is predominant, with aggression on the order of 176.5 b/m/n. The Anopheles gambiae complex is predominant in the semi-rural zone at the periphery of the city with 26.05 b/m/n. Other mosquitoes are equally implicated in their aggression and nuisance to man, in particular, Mansonia africana, Mansonia uniformis and Aedes aegypti. A geographical distribution map has been established for the preponderant species in Kinshasa.
