TLDR
Two of the species found breeding in close association with sheep and goats are potential vectors of bluetongue virus and the possibility of a third species being a vector in Cyprus is discussed.Abstract:
During an epizootic of bluetongue virus disease of sheep in Cyprus in the autumn of 1977, 16 species of Culicoides were collected in light-traps and 4 species were collected from breeding sites. Two of the species found breeding in close association with sheep and goats are potential vectors of bluetongue virus. The possibility of a third species being a vector in Cyprus is discussed.read more

Culicoides biting midges: their role as arbovirus vectors.
TL;DR: Those aspects of midge biology facilitating disease transmission are dealt with, the factors controlling insect-virus interactions at the individual insect and population level are described, and the far-reaching effects that certain components of climate have upon the midges and, hence, transmission potential are illustrated.

Climate change and the recent emergence of bluetongue in Europe.
TL;DR: This work suggests that this spread has been driven by recent changes in European climate that have allowed increased virus persistence during winter, the northward expansion of Culicoides imicola, the main bluetongue virus vector, and, beyond this vector's range, transmission by indigenous European Culicoide species — thereby expanding the risk of transmission over larger geographical regions.

Bluetongue epidemiology in the European Union.
TL;DR: Central and northern Europe is now at risk from bluetongue virus, according to the World Health Organization.

Bluetongue virus in the Mediterranean Basin 1998-2001.
P.S. Mellor,E.J. Wittmann +1 more
TL;DR: Recently the virus causing this disease has extended its range northwards into areas of Europe never before affected and has persisted in many of these locations causing the greatest epizootic of the disease on record.

Bluetongue in Europe: past, present and future
TL;DR: The expansion of BTV in Europe has forced a re-evaluation of the importance of Palaearctic Culicoides species in transmission, as well as the importanceof secondary transmission routes, such as transplacental transmission, in facilitating the persistence of the virus.

Bluetongue of Sheep in Cyprus
TL;DR: A number of outbreaks of Bluetongue have been observed in sheep in Cyprus at recurrent intervals since, 1924, and the original Cyprus virus attenuated at Onderstepoort by serial passage through chick embryos was used with success in subsequent outbreaks.

The origin of blood meals of female Culicoides pallidipennis trapped in a sheepfold in Israeil.
TL;DR: Precipitin tests were carried out on blood meals of 269 female Culicoides pallidipennis trapped over a period of 12 months in the sheep pens of the Veterinary Institute at Bet Dagan, Israel, finding that 44.2% of the meals were not identified, and the monthly average “forage ratio” for cattle during the trapping period was 1.3, whereas for sheep it was 0.2.

A latex agglutination test for the identification of blood-meals of Culicoides (Diptera: Ceratopogonidae)
TL;DR: Detergents commonly used in collecting midges had no effect on the latex agglutination test, but 0–01% mertbiolate, often used as a preservative, caused auto-agglutination and cannot be used when this test is to be applied.
