| molecular differentiation of the old world culicoides imicola species complex (diptera, ceratopogonidae), inferred using random amplified polymorphic dna markers. | samples of seven of the 10 morphological species of midges of the culicoides imicola complex were considered. the importance of this species complex is connected to its vectorial capacity for african horse sickness virus (ahsv) and bluetongue virus (btv). consequently, the risk of transmission may vary dramatically, depending upon the particular cryptic species present in a given area. the species complex is confined to the old world and our samples were collected in southern africa, madagascar ... | 2001 | 11472544 |
