Biodiversité des mouches des fruits (Diptera : Tephritidae) en vergers de manguiers de l’ouest du Burkina Faso : structure et comparaison des communautés de différents sites uri icon

abstract

  • Introduction. An inventory of Tephritidae species in mango orchards of Western Burkina Faso was conducted from December 2007 to December 2009. Materials and methods. A detection trapping was conducted in mango orchards using the Torula yeast as bait placed in Mac Phail traps. Results and discussion. Identification and enumeration of captured Tephritidae revealed 18 species, nine of the genus Ceratitis, seven of Dacus and two of Bactrocera. Ceratitis cosyra and Bactrocera invadens (respectively 53.02% and 36.19% of the whole Tephritids captured) were found to be the dominant species. We have demonstrated a strong similarity between the Tephritidae communities in the different sites investigated (similarity indices varied between 42.86% and 100%); this similarity could be explained by the uniformity of the climatic conditions and by the homogeneity of vegetation in the study area. The proximity of vegetable plots and the diversity of local fruit-tree hosts of Tephritidae around the mango orchards could be the cause of the high species richness we observed. Conclusion. Our study revealed a diversity of Tephritidae in the investigated area which has homogeneous communities of species. These results should be complemented by the identification of species associated with damage to mango and evaluation of their importance. They now suggest the possibility of developing, against these pests, a strategy common to all localities of the investigated area in western Burkina Faso.
