Résumé : Culicoides spp. are small biting midges responsible for the transmission of several arboviruses of veterinary importance, including the bluetongue virus, the Schmallenberg virus and the African horse sickness virus. Although there were two major bluetongue outbreaks in Macedonia (in 2001 and 2014), the Culicoides involved in the transmission were never investigated. Hence, this study aimed to determine the Culicoides species diversity and abundance in Macedonia. Collections were performed in 2016 on seven cattle dairy farms using OVI-light/suction traps. From May to October, the sampling was twice per month for two consecutive nights. In November and December, there was only one sampling per month and for one night only. The collected Culicoides were morphologically identified according to the wing patterns of the females and the genital morphology of the males. A subset of randomly selected females belonging to Culicoides obsoletus/Culicoides scoticus were identified to species level by PCR. Overall, 138 collections were performed and a total of 109,866 Culicoides were identified. The identified Culicoides belonged to at least 9 species: C. obsoletus s.l./C. scoticus, Culicoides imicola, Culicoides pulicaris, Culicoides punctatus, Culicoides newsteadi, Culicoides circumscriptus, Culicoides flavipulicaris, species of the Odibilis and Nubeculosus groups. C. obsoletus s.l./C. scoticus were the most abundant species (61.3%), with peak activity in June. The PCR showed a dominance of C. obsoletus s.l. (82.6%) may include cryptic species, over C. scoticus (14.7%). These results can be used as a baseline for future research and can help in identifying risk areas for Culicoides borne viruses in Macedonia. (Texte integral)
