| Research Abstract |
The naturalization of the exotic honeybee Apis mellifera may have great detrimental effects on closely related native Japanese honeybee A.cerana. In order to assess its population genetics and reproduction, we estimated the genetic structure of A.cerana in wild queens and cross fertilization queens by analyzing microsatellite DNA markers. Thelytoky is common in the cross fertilization queens, but it occurs with completely sexual production in wild queens. DNA microsatellite markers provided confirmation of the low levels of genetic variation in A.cerana detected by mtDNA analysis. As a result the low genetic variation was suggested with influence by a exotic honeybee.
