Sumario:The abundance and species diversity of tabanids were evaluated by trapping of insects using Vavoua traps, during the rainy season, from October 4 to November 30, 2009, in three different habitats: primary forest, secondary forest and village, in the biosphere reserve Ipassa-IRET Makokou in Gabon. Eight species belonging to three genera of tabanids have been identified for a total of 402 specimens caught. The tabanid species numerically the most abundant were: Tabanus secedens Walker, 1854 (55.2%), Tabanus obscurehirtus Ricardo, 1908 (13.9%), Chrysops dimidiatus Wulp, 1885 (11.2%) and Chrysops silaceus Austen, 1907 (10,7%). The less abundant species were Tabanus par Walker, 1854 (3.2%), Tabanus besti arbucklei Austen, 1912 (3%), Tabanus marmorosus congoicola Bequaert, 1930 (1%) and Ancala fasciata fasciata (Fabricius, 1775) (0.5%). Specimens of the genera Tabanus and Chrysops could not be identified, these insects represented respectively 0.7% and 0.5% of the insects trapped. The highest proportion of tabanids was trapped in secondary forest (75.1%) and the lower in primary forest (4.5%).
