Oral Presentation
Honey bees, Apis mellifera L., are essential commercial pollinators. Honey bees not only enhance agricultural production but also play a crucial role in maintaining ecosystem stability, biodiversity, and conservation. Pollen is a vital resource for the bee colony, serving as a primary source of protein essential for brood development. In addition, it also provides critical dietary component, such as lipids, sterols, vitamins, and minerals. Honey bee collected pollen in a specific region reflects the diversity of vegetation utilized by the bee, varying according to local flora and blooming patterns. It also provides reliable insights into the floral resources available to bees and their foraging preferences among the co-flowering plant species. For the present palynology study, pollen was collected using a pollen trap in the Southeast Region throughout the years 2022 to 2024 to assess seasonal and locational variations in bee forage across this region. The collected bee pollens were processed through acetolysis for their identification to the genus and species level. This study found Southeastern region as floristically diverse with a wide range of pollen sources throughout the study period.
