ABSTRACT

Beetles of Staphylinidae family are predators of animal disease vectors and insect pests associated with field crops and greenhouse crops. The objective of this study, which focuses on these beetles, is to determine the abundance and diversity of Staphylinidae in cattle farms. Three sampling sites were selected to conduct an inventory of this taxonomic group: DJERA PRODUCTION farm (Kpouèbo subprefecture), the Cattle Breeding Center (located on Yamoussoukro-Bouaflé highway), and Youssouf Fofana Agropastoral Company (Mankono) site. The dung trap was used to collect Staphylinidae at these sites. It yielded 248 individuals, representing 18 species across six subfamilies. The species Omalium sp. was the most abundant (99 individuals), accounting for 39.92% of the total collected population. The largest number of individuals was collected at Kpouèbo site (121 individuals), and the smallest number at Mankono site (44 individuals). Yamoussoukro and Kpouèbo sites recorded the same number of species, namely six (6 species). Kpouèbo site is relatively more diverse, with a Shannon index of H = 1.628. The abundance and diversity of Staphylinidae vary significantly from one site to another.
