Identification of Culicoides biting midges to species has attracted attention due to the recent outbreak of bluetongue disease in Northern Europe. Identification of Culicoides to species level has been based on morphological characters and is difficult as several species belonging to species complexes are hard to distinguish. We evaluated the use of the(More)
Culicoides vectors are critical to the survival and transmission of bluetongue virus as infection only occurs in areas or regions where competent vectors are present. The success of Culicoides biting midges as vectors is mainly related to their vast population sizes and to their means of dispersal. Their choice of host for blood feeding is sparsely(More)
Host preference studies in haematophagous insects e.g. Culicoides biting midges are pivotal to assess transmission routes of vector-borne diseases and critical for the development of veterinary contingency plans to identify which species should be included due to their risk potential. Species of Culicoides have been found in almost all parts of the world(More)
DNA sequences offer powerful tools for describing the members and interactions of natural communities. In this study, we establish the to-date most comprehensive library of DNA barcodes for a terrestrial site, including all known macroscopic animals and vascular plants of an intensively studied area of the High Arctic, the Zackenberg Valley in Northeast(More)
BACKGROUND In the context of a major monitoring program of Culicoides in Denmark and Sweden due to the appearance of bluetongue disease in 2007-2008, a large number of specimens were collected by light traps and sorted morphologically, with COI barcodes generated for selected specimens. NEW INFORMATION Three species are described as new to science based(More)
In light of the emergence of bluetongue in northern Europe, populations of Culicoides species were monitored in 2007-2008 by means of Onderstepoort blacklight suction traps operating at livestock farms in Sweden. The location of the 22 sampling sites ranged from about latitude 55 degrees N to about 68 degrees N. A total of 61,669 male and female Culicoides(More)
After the introduction of bluetongue in northern Europe in 2006, populations of Culicoides have been monitored in many European countries. Large quantities of Culicoides specimens shall be determined to species, and it is thus important to find reliable morphological characters that are visualized in a stereomicroscope. Culicoides obsoletus, Culicoides(More)
In the past decade biting midges of the subgenus Avaritia (Diptera: Ceratopogonidae) have been popular subjects of applied entomological studies in Europe owing to their implication as biological vectors in outbreaks of bluetongue and Schmallenberg viruses. This study uses a combination of cytochrome oxidase subunit I barcode sequencing and geometric(More)
This study presents descriptive statistics and community analysis of adult biting midges trapped at 16 livestock farms by means of light traps on Zealand and Lolland-Falster, Denmark. A total of 9,047 male and female Culicoides divided into 24 species, were caught. Biotic and abiotic factors ranging from presence of different host species (cattle or(More)
