Abundance and species diversity of tabanids (Diptera) in the biosphere reserve Ipassa-Makokou (Gabon) during the rainy season 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 %).
