| host use patterns of culicoides spp. biting midges at a big game preserve in florida, u.s.a., and implications for the transmission of orbiviruses. | culicoides spp. biting midges (diptera: ceratopogonidae) are vectors of pathogens that have a significant economic impact on the livestock industry. white-tailed deer (odocoileus virginianus), a farmed species in the u.s.a., are susceptible to two culicoides spp. borne orbiviruses: bluetongue virus and epizootic haemorrhagic disease virus. elucidating host-vector interactions is an integral step in studying disease transmission. this study investigated the host range of culicoides spp. present o ... | 2019 | 30063255 |
| laboratory studies on the oviposition stimuli of culicoides stellifer (diptera: ceratopogonidae), a suspected vector of orbiviruses in the united states. | biting midges of the genus culicoides (diptera: ceratopogonidae) exert a significant impact on animal agriculture worldwide because they transmit bluetongue virus (btv) and epizootic hemorrhagic disease virus (ehdv) to ruminants. without effective vaccines, btv/ehdv vector management strategies are needed, particularly in commercial white-tailed deer (wtd) facilities. however, detailed information on the ecology of midge immatures in/around cervid operations is currently lacking. towards filling ... | 2018 | 29769137 |
| habitat associations of culicoides species (diptera: ceratopogonidae) abundant on a commercial cervid farm in florida, usa. | biting midges in the genus culicoides (diptera: ceratopogonidae) transmit bluetongue virus (btv) and epizootic hemorrhagic disease virus (ehdv) to ruminants, thus exerting a significant economic impact on animal agriculture worldwide. however, very little is known about the larval habitat characteristics of culicoides species associated with btv/ehdv transmission, particularly in southeastern usa, limiting the establishment of effective midge control strategies. in this study, we examined the ha ... | 2019 | 31349854 |
| prospective study of epizootic hemorrhagic disease virus and bluetongue virus transmission in captive ruminants. | bluetongue virus (btv) and epizootic hemorrhagic disease virus (ehdv) cause hemorrhagic disease (hd) in wild ruminants and bluetongue disease (bt) and epizootic hemorrhagic disease (ehd) in livestock. these viruses are transmitted by biting midges in the genus culicoides (family ceratopogonidae). mortality from this disease can reach 90% in certain breeds of sheep and in white-tailed deer (odocoileus virginianus). from january until december of 2012, we conducted a prospective study to determine ... | 2020 | 32083292 |
