Distribution des Glossines vecteurs de la Trypanosomose humaine africaine dans le Parc National de Moukalaba Doudou (Sud-ouest Gabon)

Abstract

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 fusca congolensis (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. Keywords:
