| Abstract | Objectifs : Dans le but de connaitre la densité apparente et la composition spécifique des glossines dans un ancien foyer de la Trypanosome humaine africaine au Gabon, une enquête entomologique a été menée dans deux biotopes du Parc National de Moukalaba Doudou (Sud Gabon) : le village Doussala et la forêt attenant à ce village.Méthodologie et résultats : Les captures ont été effectuées à l’aide de pièges Vavoua placés en forêt et au village Doussala durant la grande saison sèche. Au total, 4071 glossines ont été capturées : 3141 (77,2%) l’ont été en forêt et 930 (22,8%) au village. En forêt, six espèces ont été capturées avec des abondances différentes : G. fuscipes fuscipes (DAP=11,1 G/P/J), G. nashi (DAP=0,49 G/P/J), G. frezili (DAP=0,25 G/P/J),G. fusca congolensis (DAP=0,18 G/P/J), G. palpalis palpalis (DAP=0,09 G/P/J) et G. tachinoides (DAP=0,01 G/P/J). Tandis qu’au village, cinq espèces ont été identifiés, il s’agit de G. fuscipes fuscipes qui a une DAP de 3,48 G/P/J. Les autres espèces à savoir G. tachinoides, G. palpalis palpalis, G. nashi et G frezili ont des densités apparentes respectivement de 0,06 G/P/J ; 0,02 G/P/J ; 0,01 G/P/J et 0,01 G/P/J.Conclusion et application : Tous les éléments du complexe pathogène nécessaire à la transmission de la Trypanosome humaine africaine sont présents dans ce parc. Ces résultats bien que préliminaires invitent àélaborer des stratégies de lutte et de contrôle des vecteurs de parasitoses.Mots clés : piège Vavoua, Doussala, Trypanosome, Glossines, Gabon. Distribution of biological vectors of human African Trypanosomiasis in the National Park of Moukalaba Doudou (South Gabon).Objective: In order to know the apparent density and specific composition of the flies in a former home of human African trypanosomes in Gabon, an entomological investigation was conducted in primary forest and Doussala village in the National Park of Moukalaba Doudou (Gabon South). Methodology and Results:The catches were taken with the Vavoua traps placed in primary forest and the village Doussala during the long dry season. A total of 4071 tsetse with 3141 (77.2%) in the forest and 930 (22.8%) in the village were captured. In the forest, sixs pecies were captured with different abundances G. fuscipes fuscipes (DAP=11.1 G/ P/ J), G. nashi (DAP=0.49 G/ P/ J), G frezili (DAP=0.25 G / P /J), G fuscacongolensis (DAP=0.18 G / P /J), G palpalis palpalis (DAP= 0.09 G / P /J) and G tachinoides (DAP= 0.01 G/ P /J).While in the town five species have been identified, it is G. fuscipes fuscipes DAP which has a 3.48 G / P/ J. Other species namely G tachinoides, G palpalis palpalis, G. nashi and G frezili have apparent densities of 0.06 G / P /J, respectively; 0.02 G / P /J; 0.01 G / P /J and 0.01 G / P/ J.Conclusion and Application:All elements of the complex pathogenic necessary for the transmission of human African trypanosomes are present in the park. These results, although preliminary invite to develop strategies of struggle and control parasitosis vectors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
