Abstract :
[en] Several species of Culicoides (Diptera: Ceratopogonidae) biting midges serve as biological vec{ors for the bluetongue virus (BTV) and the recently described Schmallenberg virus in northern Europe. since their recent emergence in this part of the continent, these diseases have caused considerable economic losses to the sheep and cattle industries. Much data is nou, âvailable that describe the distribuüon, population dynamics, and feeding habits of these insects. However, little is known regarding the presence of culicoides in unusual habitats such as peaÿ marshes, nor their potential vector capacity. This study evaluated Culicoides biting midges present in the bogs of a Belgian nature reserve compared to those residing at a nearby cattle farm. Culicoides were trapped in 2011 at four different sites (broadleaved and coniferous forested areas, open environments, and at a scientific station) located in the Hautes Fagnes Nature Reserve (Belgium). An additional light trap was operated on a nearby caftle farm. High numbers of biting midges were captured in the marshy area and most of them were Culicoides impunc{atus, a potential vector of BïV and other pâthogens. ln addition, fewer numbers of c. obsoletus/c. scoticus species, C. chiopterus, and C. dewulfi were observed in the bogs compared to the farm. The wet environment and oligotrophic nature of the soil were probably responsible for these changes in the respective populations. A total of 297,808 Culicoides midges belonging to 27 species were identified during this study and 3 of these species (C. sphagnumensis, C. clintoni and C. comosioculatus) were described in Belgium for the first time.
