| Popis: | To investigate the spatial and temporal diversity of tsetse flies, vectors of trypanosomosis, in Ivory Coast, surveys were conducted on the Comoe River in three sites located in different ecoclimatic zones: north, center and south. They were carried out during the dry and rainy seasons. For each site and season, the flies were captured during five consecutive days in biconical traps arranged in transects perpendicular to the Comoe River. In Kafolo in savanna, three species and subspecies were captured regardless of the season: Glossina palpalis gambiensis, G. tachinoides and G. medicorum. In Aboisso-Comoe and Groumania, in forest and forest-savanna transition areas, respectively, only G. palpalis palpalis was captured. The apparent density per trap, all species combined, was higher in Kafolo than in Groumania and Aboisso-Comoe. It was 9.48 tsetse flies (tf)/trap/day (standard deviation [SD] = 26.30) in Kafolo, 0.79 tf/trap/day (SD = 2.65) in Groumania, and 0.18 tf/trap/day (SD = 0.58) in Aboisso Comoe in the dry season. In the rainy season, it was 3.64 tf/trap/day (SD = 9.76) in Kafolo and 1.42 tf/trap/day (SD = 2.35) in Groumania. These results show that the diversity of tsetse species along the Comoe River depends on the biotope conservation, as illustrated by the gradual disappearance of species such as G. morsitans submorsitans which was not captured during the study. We also confirm that only the major vector of human African trypano-somiasis, G. palpalis s.l., can adapt to humans. |
