【 摘 要 】
Abidjan (Côte d’Ivoire), investigations were conducted to assess the tsetse fly densities as well as infection with trypanosomes. Catches were carried out during the rainy season and dry season with Vavoua traps laid during four consecutive days in different sites (Banco forest, Abidjan zoological park, area of the University of Abobo-Adjamé). One species of tsetse fly (Glossina palpalis palpalis) and two species of trypanosomes (Trypanosoma congolense, T. vivax) have been revealed. The apparent density per trap per day (DAP) is very high in the zoological park, 54.8 tsetse fly/trap/day during the dry season and 28.1 during the rainy season. At the University of Abobo-Adjamé, the DAP is respectively 13.5 and 8.1 tsetse fly/trap/day during the rainy season, and in the dry season it is only 0.9 and 0.8 in the Banco Forest. The physiological age on all sites is as follows: 57.5% of old parous, 39% of young parous and 3.6% of nulliparous in the rainy season. These proportions vary to 51.9% of young parous, 47.1% of old parous and 1% of nulliparous in the dry season. The overall infection rate is estimated at 20.7% in the rainy season and 20% in the dry season. Statistical analysis have showed a significant difference in the distribution of infection rates.
