摘要： Declining wild honeybee (Apis) resources could cause the extinction of symbiotic relationships between plants and honeybees, reducing food production. Therefore, the protection of genetic resources and the diversity of wild honeybees are crucial. This study examined the honeybees in a plant nature reserve (Leigongshan) to better understand their genetic status in a purely natural state and explored the potential role of this plant nature reserve on pollinators. Nuclear (15 microsatellites) and mitochondrial markers (tRNA(leu) similar to COII and COI) were used to investigate the genetic resources and diversity of eastern honeybees (Apis cerana). Here, 31 new honeybee haplotypes were discovered from the inside and outside regions of the reserve. The honeybees showed a high genetic diversity level (He: 0.6564 +/- 0.1594, Na: 3-18, PIC: 0.6191 +/- 0.1718, H-d in tRNA(leu) similar to COII: 0.6797, H-d in COI: 0.8103), and no apparent genetic differentiation was observed between the two regions. Thus, we speculate that Leigongshan Nature Reserve protects honeybees from human disturbance and prevents a decline in their population size, preserving the honeybee genetic resources and high genetic diversity level. Furthermore, our results have revealed the practical function of the plant nature reserve on honeybee genetic resources, which explains the decreasing honeybee resources.
