Within the last few decades Culicoides spp. (Diptera: Ceratopogonidae) emerged Europe-wide as a major vector for epizootic viral diseases e.g. caused by Bluetongue (BT) or Schmallenberg virus. In accordance with the EU regulation 1266/2007, veterinary authorities are requested to determine vector-free periods for loosing trade and movement restrictions of susceptible livestock. Additionally, the widely used basic reproduction number [Formula: see text] is optionally applied for risk assessment of vector-borne diseases. Values of [Formula: see text] indicate periods with no disease transmission risk. For the determination of vector-free period and [Formula: see text] a continuously operating daily Culicoides spp. monitoring in Vienna (Austria) was established. It covered the period 2009-2013 and depicts the seasonal vector abundance indoor and outdoor. Future BT and African horse sickness (AHS) outbreak risks were estimated by projecting [Formula: see text] to climate change scenarios. Therefore, temperature-dependent vector parameters were applied.
