abstract
The insularity of Manoka is a priori favorable to trypanosomiasis eradication. Our purpose is to determine the spatio-temporal distribution, dispersion of tsetse, hosts-vectors contact areas and identifying circulating trypanosomes for efficient trypanosomiasis control. Flies were sampled using pyramidal traps during the main dry, the small and the main rainy season. They were identified, sexed, density evaluated and dissected for tenerals determination and blood meals collection. Specific PCRs were carried out for species confirmation, hosts and trypanosomes identification. Glossina palpalis palpalis, predominant and Glossina caliginea were found in Manoka. Densities were higher in mangroves and did not significantly vary between seasons. Flies were actives from 8 am to 6pm with a peak between 12 and 4 pm and a dispersal capacity up to one kilometer. Humans and wild animals were feeding hosts while Trypanosoma congolense and Trypanosoma vivax infested these flies. Mangrove seems to be the biotope to prioritize in tsetse control campaigns.
