Microorganism changes'in the"gutof Apis-melliferasurviving for long term in Camellia oleifera forests

The a-galactosides (oligosaccharides) in C. oleifera nectar and pollen causehoney bee larvae rot and worker bloat. However, honey bee colonies surviving in Coleifera forests for a long period oftime have lowrates oflarvae rots and worker bloat.but the mechanismof oligosaccharide metabolism involved is not clear. In this study, we used metagenomics and metabolomics to investigate the structure and function ofthe gut flora and thedigestion characteristicsofoligosaccharides ingut of.A. melliferaforagers (CN group) that had been in the C, oleifera forest for a long period oftime(14years), and those that had not been pollinated with oil tea (N group) after 24-h ofconsumptionofC. oleiferahoney.
