Abstract The health of bees can be assessed through their microbiome, which serves as a biomarker indicating the presence both beneficial and harmful microorganisms within bee community. This study presents characterisation bacterial, fungal, plant composition on cuticle adult bicoloured sweat ( Agapostemon virescens ). These were collected using various methods such pan traps, blue vane traps sweep netting across northern extent habitat range. Non‐destructive employed to extract DNA from whole pinned specimens these wild bees. Metabarcoding 16S rRNA, ITS rbcL regions was then performed. found that method collection influenced detection certain microbial taxa. Among methods, net samples showed lowest fungal alpha diversity. However, minor differences in bacterial or beta diversity suggest no single is significantly superior others. Therefore, combination techniques cater broader spectrum detection. also revealed regional variations core microbiome A. comprises two bacteria, three fungi association, all are commonly detected other microbes remained consistent different locations. Further extensive studies microbiomes species landscapes will help uncover crucial relationships between pollinator environment.

Planting floral resources is a common strategy for increasing the abundance and diversity of beneficial flower-visiting insects in human-modified systems. However, context local area surrounding landscape may affect attractiveness these resource provisioning plots. We compared relative effects urban land-use on bees flowering plants gardens eastern Tennessee, USA. planted four types garden plots at each five different landscapes representing variety land use: 1) Urban Garden, 2) Forage Grassland, 3) Mixed Agriculture, 4) Forest, 5) Organic Farm. Each plot type had fixed plant community one three families (Asteraceae, Fabaceae, Lamiaceae) or mix all three, were replicated sites. concurrently sampled 50 m radius (local area) around found that size display (i.e. visual flowers) flowers did not bee species richness Although there was significant positive association between developed use 2 km gardens, effect small, no relationship area. There differences composition plots, but largest determinants variation bloom. This finding promising anyone wishing to promote pollinator populations by providing more resources.
