摘要： Qualitative melittopalynological data of 34 honey samples obtained from Apis cerana and Apis mellifera between 2011 and 2012 in Mengzi (Yunnan, China) are analyzed. And trophic niche of the two bee species on pollen food resources are also investigated in the present study. Results show that a diverse spectrum of 17 pollen types was identified into 14 families, and the Asteraceae and Myrtaceae are the most frequent at non-nectar flow and the Lythraceae are most frequent at main nectar flow of pomegranate in our study area. As for trophic niche analysis of Apis cerana and Apis mellifera, the niche breadth value is 0.65 and 0.57 at non-nectar flow and 0.41 and 0.24 at nectar flow, respectively. Meanwhile, the value of trophic niche overlap index at nectar flow (0.68) is greater than that of non-nectar flow (0.61). And the value of interspecific competition index at nectar flow (0.92) is greater than non-nectar flow (0.77), too. These results may promote the development of local beekeeping and provide some reference for scholars to assess the influence of introducing exotic bees on Chinese native bees.
