Abstract The aim of this study is to identify the hematophagous flies that contribute to disease transmission in cattle. This work took place in the department of Kounahiri (Côte d'Ivoire), 520 km from the city of Abidjan in December 2022. It took place over 08 days. Tabanidae and Stomoxyinae were caught using Vavoua traps. The insects collected were then placed in a freezer for twenty minutes to kill any insects that were still alive before being stored in a vial containing 70° ethanol. The identification of the different Stomoxyinae species was then developed using the determination keys of Zumpt and the additional morphological character to better separate S. calcitrans and S. niger niger. The Tabanidae were identified using the identification keys published by Oldroyd. The Tabanidae were divided into two genera: three (03) Philipotabanus elviae and thirty-one (31) Tabanus taeniola. On the other hand, among the Stomoxyinae, we identified 18 Stomoxys indicus and 25 Stomoxys calcitrans. The apparent density (AD) was 3.208 flies per day. As for the assessment of specific densities as a function of species composition, Tabanus taeniola had a higher specific density, at 40.26%, with 31 individuals out of a total of 77 flies. In addition, the diversity of haematophagous flies in relation to the biotope gave Margalef’s diversity indices of 0.612 for Stomoxes and 0.652 for Tabanidae. We can conclude from this research that, the inclusion of mechanical vectors in vector control strategies should help to minimise the impact of biting flies on livestock.
