Chippaux Jean-Philippe auteur aut IRD Bouchité Bernard auteur aut IRD Demanou M auteur aut IRD Morlais Isbelle auteur aut IRD Le Goff Gilbert auteur aut IRD text journalArticle eng text/pdf reformatted digital access By mark-release-recapture experiments, we assessed the density of loaisis vectos, Chrysops dimidiata Wulp plus some Chrysops silacea Austen (Diptera : Tabanidae) and estimated their range of flight in the secondary forest of southern Cameroon. In 1993, the release point was at the centre of the study area and recapture points were at 1100 m radius. In 1994, releases were on the periphery of the study area and recapture sites were 400-8000 m from the release points. Results were concordant and showed Chrysops female densities of 785-3682 flies/km2. The theoretical flight range was less than 6000 m, with a maximum distance of 4500 m observed. These results are considered promising for the use of vector control methods against loaiasis.
