Abstract :
[en] Several species of Culicoides (Diptera: Ceratopogonidae) biting midges are biological vectors of bluetongue virus (BTV) and, as recently discovered, Schmallenberg virus (SBV) in northern Europe. Since their recent emergence in this part of the continent, these diseases that affect domestic and wild ruminants have caused considerable economic losses to the sheep and cattle industries. The substrates that are suitable for larval development of the main vector species are still relatively unknown. This study assessed all the substrates present in the immediate surroundings of a Belgian cattle farm and aimed to highlight the main breeding sites of these midge species. A total of 1639 immature Culicoides and 1320 adult specimens belonging to 13 species were found in 15 out of the 43 substrates studied: maize silage residues for C. obsoletus/C. scoticus, old overwintered cattle dung in the meadow for C. chiopterus and C. dewulfi, ground of a flooded meadow, green filamentous algae and underlying substrate, silt from a pond, and ground of hollows caused by the crossing of machines on a dirt track for C. festivipennis, silt from a pond for C. nubeculosus, and ground of a flooded meadow for C. lupicaris. Identification of these micro-habitats and the associations among the species they contain could allow their localization and the development of new strategies of vector control, while preventing the creation of new Culicoides larval micro-habitats. Finally, measures designed to reduce larval populations could improve efficacy of vaccination campaigns against BTV in Europe.
