Honeybees and bumblebees play a crucial role as essential pollinators. The special gut microbiome of social bees is key factor in determining the overall fitness health host. Although harbor relatively simple microbial communities at genus level, recent studies have unveiled significant genetic divergence variations gene content within each bacterial genus. However, comprehensive refined genomics-based taxonomic database specific to bee microbiomes remains lacking. Here, we first provided an overview current knowledge on distribution function bacteria, well factors that influence population dynamics. We then consolidated all available genomes bacteria species-level taxonomy, by constructing maximum-likelihood core genome phylogeny calculating genome-wide pairwise average nucleotide identity. On basis species constructed curated genomic reference database, named microbe sequence (BGM-GDb). To evaluate species-profiling performance BGM-GDb, retrieved series metagenomic data inferred composition using intra-species diversity analysis system (MIDAS), compared results with those obtained from prebuilt MIDAS database. found default BGM-GDb excelled aligned read counts richness. Overall, this high-resolution precise will facilitate research understanding community structure bees.

Abstract The gut microbiota has been linked to the pathophysiology of inflammatory bowel disease (IBD). Current animal models are limited in generation germ‐free animals evaluate roles bacteria intestinal health. Here, we used honeybee ( Apis mellifera ) as a model develop colitis‐like permeability induced by dextran sodium sulfate (DSS) treatment. We found that DSS could increase and compromise mucosal barrier honeybees, resulting decreased survival rates, midgut elongation, edema. treatment upregulated expression wnt‐1 rhomboid downregulated pathways cytochrome P450 (CYP) peroxisome proliferator‐activated receptor signaling. Moreover, disrupted structure functional profiles microbiota. Our results showed medications reduced mortality moderated leaky syndrome DSS‐treated bees. Notably, 5‐aminosalicylic acid (5‐ASA) attenuate honeybees through activating PPAR γ signaling, which mimics human. Honeybees offer promising experimental for investigating etiology diseases disentangling symbionts

Abstract Bumblebees play an important ecological economic role as pollinators in nature and agriculture. For reasons of biosecurity, many countries promote the cultivation native bumblebee species for crop pollination instead importing “alien” species. In South China, a few are considered useful this way, particularly, Bombus atripes , bicoloratus breviceps . However, whether they suitable artificial rearing forming healthy colonies pollination, remains unknown. project, queens from 3 Guizhou Province were collected started under standardized conditions. The scored based on 19 parameters, including stage colony development, number weight offspring, diet consumed. data revealed that B. had best performance, produced more workers consumed smallest diet. Next, we performed 16S rDNA sequencing bacterial communities found guts offspring workers, then correlation analysis between performance gut bacteria was conducted. Here, showed highest diversity composition, dominated by Gilliamella Snodgrassella Enterobacter Lactobacillus Firm5. higher abundance better foundation stage, later Firm5, Apibacter Bifidobacterium beneficial during stages rapid growth decline. Although do not understand all interactions yet, these correlations explain why demonstrated performance. Our provide valuable information breeding local will contribute to developing strong pollination.

Abstract The three ecologically similar species of hemipteran sucking insects, brown planthopper (BPH) Nilaparvata lugens , small (SBPH) Laodelphax striatellus and white‐backed (WBPH) Sogatella furcifera are destructive pests causing severe damage to rice throughout Asia, but they have different host plants that BPH is monophagous insect just feeding rice, WBPH SBPH oligophagous insects additionally wheat barley can also feed maize. This study was investigated the gut bacterial communities in BPH, by high‐throughput amplicon sequencing order explain differences range (SBPH>WBPH>BPH) habit (BPH with monophagy vs. oligophagy) planthoppers. It revealed flora most complex, simplest. diversity community significantly higher than SBPH, respectively, there not only significant difference α‐diversity metrics β‐diversity metrics. KEGG enrichment analysis furtherly indicated relative abundance some functional categories (including those related biosynthesis amino acids, fatty lipids carbohydrate) among which were closely their nutrient absorption metabolism. presumed composition bacteria may lead metabolism, alter habit.
