description Pig farms: reservoirs of vectors of Bluetongue and Schmallenberg viruses?. Bluetongue (BT) is a vector-borne disease that affects domestic and wild ruminants. Since its recent outbreak in northern Europe, this viral disease has caused considerable economic losses. The biological vectors of the bluetongue virus are biting midges belonging to the genus Culicoides (Diptera: Ceratopogonidae). Several light trapping campaigns targeting these adult midges have been previously conducted in Belgium within cattle and sheep farms, but none have been performed inside pig farms. This study therefore aims to assess, using light traps, the levels of Culicoides populations that may have been present inside two Belgian pig farms during the fall and winter of 2008. The presence of (potential) Culicoides vector species was demonstrated inside the pig buildings during the fall: 8 and 749 specimens belonging to 2 and 7 species were respectively trapped inside the pigsties, with the majority being Obsoletus complex females. The opening up of the buildings seemed to strongly influence their presence. Observation of the females' nutritional status suggests that these midges were likely to have fed or to have laid eggs inside the pig farms, despite the fact that pig's blood could not be identified in the abdomen of engorged females and that pig manure did not reveal the presence of larvae. Pigs could thus be involved in the maintenance of potential vector species populations of the BT virus, or of the new Schmallenberg virus.
