The intestinal microbial community composition of different bee species typically has host specificity, yet little is known about the underlying formation mechanism. There are signs that dietary habits vary in different bee species, suggesting that there may be close relationships between dietary habits and intestinal microorganisms. We explored this hypothesis by comparing the dietary habits and gut microbiota of two common bee species ( L. and ) in China. Bee bread and midgut samples from wild and laboratory-reared bees were collected, and the differences in intestinal microbial community composition and growth and development before and after the change in dietary habits of different bee species were compared. We found that the two sympatric species had different dietary specializations and similar metagenomic diversities. The microbiota composition differed between the two species. Moreover, we revealed that changes in native dietary habits destroyed the intestinal microbiota community composition, negatively affecting the growth and development of honeybees.
不同蜜蜂种类的肠道微生物群落组成通常具有宿主特异性，但对其潜在的形成机制知之甚少。有迹象表明，不同蜜蜂种类的饮食习惯存在差异，这表明饮食习惯与肠道微生物之间可能存在密切关系。我们通过比较中国两种常见蜜蜂种类（意大利蜜蜂和中华蜜蜂）的饮食习惯和肠道微生物群来探索这一假设。采集了野生和实验室饲养蜜蜂的蜂粮和中肠样本，并比较了不同蜜蜂种类饮食习惯改变前后肠道微生物群落组成以及生长发育的差异。我们发现，这两种同域分布的蜜蜂种类具有不同的饮食特化和相似的宏基因组多样性。两种蜜蜂的微生物群组成不同。此外，我们还发现，原生饮食习惯的改变破坏了肠道微生物群落组成，对蜜蜂的生长发育产生了负面影响。
