Varroa jacobsoni : ウィキペディア英語版 | Varroa jacobsoni
''Varroa jacobsoni'' is a species of mite that parasitises ''Apis cerana'' (Asian honey bees). The more damaging ''Varroa destructor'' was previously included under the name ''V. jacobsoni'', but the two species can be separated on the basis of the DNA sequence of the cytochrome oxidase I gene in the mitochondrial DNA. ==Biogeography== Prior to recent studies, ''V. jacobsoni'' was considered homogeneous; however, current research has detected genetic variance among populations by using genetic markers. This finding has led to the belief that ''V. jacobsoni'' was introduced to the Americas multiple times. The hosts switching between the eastern ''A. cerana'' and the western ''A. mellifera'' is the major factor that broadens the pathological transmission of ''V. jacobsoni''. It has spread worldwide with the exception of Australia, central Africa, and New Zealand.
