Geographic variation in the Japanese islands of Apis cerana japonica and in A. cerana populations bordering its geographic range
Genetic variation among Apis cerana japonica isolates from Japan
and Apis cerana isolates from the neighboring areas of Russia, South Korea,
and Taiwan was determined from DNA sequences of the mitochondrial DNA
non-coding region (between tRNA leu and COII). Three haplotypes were
identified among 470 colonies samples at 47 Japanese sites. All isolates
from the main Japanese Islands of Honshu, Shikoku, and Kyushu belonged to a
single haplotype, a previously reported Japan 1 haplotype. Two new
haplotypes were found on the far southern Japanese islands of Amami-Oshima
and Tsushima (the Japan 3 and Japan 4 haplotypes, respectively). The A.
cerana from Russia and South Korea were the Japan 1 isolate, the A. cerana
from Taiwan was the previously known Taiwan haplotype. Our studies showed
little genetic variation in the mtDNA of A. cerana japonica, indicating that
this genomic region is of limited use for detecting genetic variation among
closely related populations of A. cerana
