Concordance between the mitochondrial haplotypes of the Eastern honey bee, Apis cerana, and its ectoparasitic Varroa mites across the Isthmus of Kra in Thailand has suggested that local host–pathogen co-evolution may be responsible for the geographic distribution of particular genotypes. To investigate nuclear microsatellites population structure in A. cerana, single workers of A. cerana colonies...
Summary. New investigations into the biogeography of Asian honey bees are bringing to light previously unrecognized species. On the Indonesian island of Sulawesi, morphometrically distinct populations of Asian cavity-nesting honey bees occur in close sympatry. One population is the widespread species Apis cerana; the other has been proposed as a separate species, A. nigrocincta. A non-coding region...
