主 题：Bombus terrestris gut microbiota immunity Lactobacillus melliventris transcriptome
摘 要：Bumblebees are important pollinators in agricultural ecosystems,but their abundance is declining *** is an urgent need to protect bumblebee health and their pollination *** possess specialized gut microbiota with potential to be used as probiotics to help defend at-risk bumblebee ***,evidence for probiotic benefits on bumblebees is ***,we evaluated how supplementation with Lactobacillus melliventris isolated from bumblebee gut affected the colony development of Bombus *** native strain colonized robustly and persisted long-term in bumblebees,leading to a significantly higher quality of ***,the tyrosine pathway was upregulated in the brain and fat body,while the Wnt and mTOR pathways of the gut were ***,the field experiment in the greenhouse revealed the supplementation of *** led to a 2.5-fold increase in the bumblebee survival rate and a more than 10%increase in the number of flowers visited,indicating a better health condition and pollination ability in field *** study represents a first screening for the potential use of the native gut member,***,as probiotic strains in hive supplement for bumblebee breeding,which may be a practical approach to improve immunity and hive health.
