Evolution de la Pression Glossinaire Ă la Station dâAvĂ©tonou au Sud-Ouest du Togo
La station dâAvĂ©tonou constitue un site de rĂ©servoir de vecteur de glossine Ă cause de sa faune sauvage importante et son biotope favorable car elle est proche du fleuve Zio et jouit dâun climat relativement humide et dâune vĂ©gĂ©tation constituĂ©e de forĂȘt galerie et de savane arborĂ©e. Aussi, la prĂ©valence de la maladie dans les troupeaux ne cesse de croĂźtre dâannĂ©e en annĂ©e et lâĂ©levage bovin dans la zone nâa cessĂ© dâenregistrer des difficultĂ©s dâordre pathologique et Ă©conomique liĂ©es Ă la prolifĂ©ration et aux menaces des glossines dans le milieu. Cette Ă©tude a pour objectif de faire lâĂ©tat des lieux et actualiser les rĂ©sultats de recherche jadis acquis dans les annĂ©es 1980 par Mawuena et reprise en 2011 par Talaki afin de rechercher dans lâavenir une approche de solution Ă ce problĂšme. Pour se faire, des enquĂȘtes entomologiques et parasitologiques ont Ă©tĂ© menĂ©es en 2016 Ă la station dâAvĂ©tonou et dans les villages environnants. Les rĂ©sultats ont montrĂ© que la densitĂ© moyenne des glossines est passĂ©e de 0,2 (1986) Ă 2,2 (2011) puis Ă 1,06 (2016) soit une augmentation de plus de cinq fois. Dans le mĂȘme ordre, la prĂ©valence de la maladie est passĂ©e de 4,7% Ă 22,78% puis Ă 23,8%. Trypanosoma vivax et Glossina palpalis palpalis ont Ă©tĂ© les espĂšces de parasites et de vecteurs les plus dominants. Cette Ă©volution sans cesse croissante de la prolifĂ©ration des glossines et de son infestation risque de compromettre lâĂ©levage bovin dans le milieu; des mesures de lutte contre le vecteur doivent ĂȘtre entreprises pour prĂ©server la santĂ© des troupeaux et sauvegarder lâĂ©levage des bovins en gĂ©nĂ©ral dans la zone.
The Avetonou station is one of the oldest animal production research stations in the sub-region of West Africa. The new directions of the station in recent years no longer allow the continuation and the sustainable achievements of research, especially in the fight against the animal trypanosomiasis undertaken since the 1980s. Also, it is necessary to point out that since then, cattle breeding in the area have not stopped recording pathological and economical difficulties due to the proliferation and threats of the tsetse in the area. This paper, however, focuses on highlighting the point and updating the research results previously acquired in the 1980s by Mawuena and recovered in 2011 by Talaki. This is with the aim of seeking a solution approach in addressing this problem in the future. To do this, entomological and parasitological surveys were conducted in 2016 in the station of Avetonou and in the surrounding villages. The results showed that the average density of the tsetse went from 0.2 (1986) to 2.2 (2011), and then to 1.06 (2016) resulting in an increment of more than five times. Similarly, the prevalence of the disease rose from 4.7% to 22.78%, and then to 23.8%. Trypanosoma Vivax and Glossina palpalis palpalis were the most dominant species of parasites and the vectors. The wooded vegetation of the station, the demographic pressure on the flora, and the proliferation of wild animals might be the reasons for this significant infestation
