[Ecology of tsetse flies in the preforested area of the Ivory Coast. Relation to human trypanosomiasis and possibilities for control].
This paper gives the results of a tsetse fly research program in the preforested area of Ivory Coast. The main investigation tool was the Challier-Laveissière's biconical trap. The ecodistribution, resting and pupal sites of the principal tsetse species, G. palpalis, G. pallicera and G. nigrofusca were described in the T. b. gambiense sleeping sickness focus of Vavoua. Population dynamics, host preferences, activity cycles were compared between tsetse populations in plantations and village surroundings. Man-fly contact was of high intensity where human habitat is scattered in plantations but in village tsetse flies used to feed mainly on pigs. Resettlement of scattered populations can be considered as a preventive measure against sleeping sickness transmission. Experiments on tsetse flies control by insecticides along edges, associated with insecticidal impregnated screens, were considered as promising.
