Impact of non-native honeybee and the parasite species on native honeybee Apis cerana.

外来蜜蜂的归化可能会有很大的不利影响，密切相关的本地日本蜜蜂A. cerana。为了研究东方蜜蜂的种群遗传学和繁殖规律，本研究利用微卫星DNA标记对东方蜜蜂的野生蜂王和异花受精蜂王进行了遗传结构分析。交配在异花受精的蜂王中很常见，但在野生蜂王中完全有性生殖时也会发生。DNA微卫星标记证实了线粒体DNA分析检测到的东方蜜蜂低水平的遗传变异。结果表明，低遗传变异与外来蜜蜂的影响。

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.
