“…Virus dispersal may be enhanced by Culicoides feeding on multiple host species (Mellor et al, 2000;Calvo et al, 2012), and wild ruminants may serve as reservoirs for viruses (Linden et al, 2008). Moreover, these biting midges are able to take blood from engorged mosquitoes, and this indirect acquisition of vertebrate blood could also play a role in pathogen transmission cycles (Kremer et al, 1974;Ma et al, 2013).…”

a b s t r a c tSome Culicoides biting midge species (Diptera: Ceratopogonidae) are biological virus vectors worldwide and have recently been associated with outbreaks of important epizootic diseases such as bluetongue and Schmallenberg in northern Europe. These diseases, which affect domestic and wild ruminants, have caused considerable economic losses. Knowledge of host preferences of these biting midges -especially of the relevant vectors of arboviruses near farms, such as Culicoides obsoletus in northern Europe -is essential to understand pathogen transmission cycles and the epidemiology of associated diseases. This study aimed to determine host preferences of C. obsoletus using an in-field flight tunnel containing pairs of calf, sheep, chicken, and human hosts (and controls) and a laboratory two-choice bioassay containing volatile extracts of host skin (and controls). Behavioural responses of nulliparous C. obsoletus females in the in-field flight tunnel showed a preference for human (but also calf and sheep) hosts, probably due to their exhalation of greater quantities of carbon dioxide. The laboratory experiment revealed that volatile organic compounds released from the skin of chicken and sheep seemed to attract this species. Culicoides obsoletus, thus, seems to have a wide host range and to be particularly attracted by humans under field conditions. A better understanding of vector-host interaction could enable the development of control strategies against adult biting midges, by exploiting insect-repelling or -attractive semiochemicals. Volatile extracts of chicken and/or sheep skin could be used to identify volatile compounds attractive to C. obsoletus, which in turn could be used in baited traps.

“…Antibodies against BTV have been reported in European reed deer shortly after being detected in domestic livestock (Linden et al 2008, Ruiz-Fons et al 2008, Rodriquez-Sanchez et al 2010. Occasionally, contact of wild ungulates with BTV has been reported in geographic regions where BTV has not been found in domestic livestock (Garcia et al 2009).…”

“…after natural or experimental infection of blesbock (Damaliscus pygargus) and mountain gazelle (Gazella gazella) no clinical signs of BT have been shown (Shimshony et al 1988, Bender et al 2003. The BTV natural infection of moose (Alces alces) and roe deer (Capreolus capreolus) has been recognized on the basis of the presence of specific antibodies and/or viral RNA in samples of blood taken from infected animals (Linden et al 2008, Rodriquez-Sanchez et al 2010.…”

“…The highest titres of BTV antibodies have been detected in samples of sera taken from free-ranging European red deer and fallow deer (Dama dama) from Cervinae subfamily (Ruiz-Fons et al 2008, Garcia et al 2009, Linden et al 2009). The RNA of BTV serotype 8 was detected by Real-Time RT-PCR (rRT-PCR) in naturally-infected wild deer in Belgium (Linden et al 2008) and BTV1 and BTV4 genetic material in blood of European red deer and mouflons in Spain (Garcia et al 2009) while BTV1 and BTV8 RNA in red deer in France (Rossi et al 2010). As for domestic ruminants, BTV transmission among wildlife depends almost exclusively on the presence of the Culicoides vector in the environment.…”
