    STUDY ON CERTAIN ASPECTS OF VECTOR CAPACITY OF CULICOIDES SPECIES IN RELATION TO BLUETONGUE
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2006) SATHEESHA, S- P.
    Culicoides flies are tiny insects commonly known as â biting midgesâ ?. These midges are the most abundant and smallest haematophagous insects occurring throughout most of the inhabited world. They are the pests of veterinary and medical importance and inflict painful bites. In addition to feeding on blood of domestic animals and man, they cause annoyance and allergic reactions. However, their importance lies in the transmission of a greater number of assorted pathogens of human, domestic and wild animals. But it is as vectors of arboviruses, particularly arboviruses of domestic livestock, that they achieve their prime importance. To date, over 50 viruses have been isolated from Culicoides species. Among these, bluetongue virus (BTV) causes disease of such international significance that it has been allocated OlE list A status. The resultant consequence is the trade barrier on movement of ruminants, their germplasms and other animal products, thus, disrupting the international commerce (Mellor, 1996).
