[Dispersion of Anopheles gambiae s.l. in an urban zone of Ouagadougou (Burkina Faso)].
Dispersion of Anopheles gambiae s.l. from larval breeding places was examined in the town of Ougadougou, Burkina Faso. A suitable study area was chosen, characterized by high concentration of larval breeding places along a water reservoir. Mosquito density per room was calculated from the results of pyrethrum spray catches carried out on a series of seven groups of collecting stations along a transect from 100 to 1050 m from the water reservoir area. High density and uniform distribution of houses and human host in the urban area appear associated with a remarkably low degree of dispersion since most of An. gambiae s.l. were collected within 200 m (males) or 300 m (females) from the breeding sites. Malaria transmission is consequently very focal in these conditions.
