title: [Infection of Glossina palpalis palpalis (Diptera, Glossinidae) by trypanosomes in the forest zone of Gagnoa in the Ivory Coast].
abstract: 2,153 Glossina palpalis palpalis caught in biconical traps from different biotopes in relation with human activities in the forest areas of Côte d'Ivoire were used to calculate the trypanosome infection rates. The results showed that there was no preferential biotope for Glossina infected by trypanosomes. The most widespread species of trypanosomes infecting Glossina p. palpalis is T. congolense (10.13%) followed by T. vivax (8.22%) and seldomly by T. brucei (0.70%). Female Glossina are infected with trypanosomes (21.27%) more than the male ones (13.56%). Regarding female Glossina, the physiological age concerned by the first infection of T. vivax, T. congolense and T. brucei reached respectively 5, 15 and 35 days. These different infection rates vary in relation to seasons.
