| molecular identification of western european species of obsoletus complex (diptera: ceratopogonidae) by an internal transcribed spacer-1 rdna multiplex polymerase chain reaction assay. | in southern europe, orbiviral diseases such as bluetongue (bt) have been assumed to have been largely transmitted by the classical afro-asian vector culicoides imicola kieffer (diptera: ceratopogonidae). recent outbreaks have occurred in regions where c. imicola is normally absent, supporting the theory that other species belonging to the obsoletus or pulicaris complexes may play a role in bt virus transmission. investigations of the ecology of the species within the former group are hampered by ... | 2007 | 18047201 |
| culicoides midges (diptera: ceratopogonidae) as vectors of orbiviruses in slovakia. | in recent years, rapid spread of culicoides-borne pathogens such as bluetongue (bt) and schmallenberg viruses have been reported in europe. in this study we examined the culicoides populations in farms with wild and domestic ruminants in eastern slovakia with the aim to confirm the presence of biting midges serving as potential vectors of important pathogens. the main vector complexes were the obsoletus complex (54%; n=4,209) and the pulicaris complex (23%; n=1,796). to estimate the relative abu ... | 2014 | 25273963 |
| eco-climatic indicators for three culicoides species of the obsoletus complex in italy. | bluetongue, schmallenberg and african horse sickness viruses are transmitted by vectors belonging to the genus culicoides (diptera: ceratopogonidae). among this genus, species of the obsoletus complex play a crucial role in europe. in italy the complex includes three species: culicoides obsoletus sensu strictu, culicoides scoticus and culicoides montanus. these three sibling species were identified in 80 collection sites across italy through a multiplex pcr test. sixty‑four sites were classified ... | 2016 | 27723029 |
