Attractive planting of species of potentially expanding bee pastures for bees
ŠEBESTA, Tomáš
This diploma thesis entitled "Attractiveness of Planting Species with a Potential to Extend Bee Forage for Bees" discusses pollen and nectar plants planted in the Brník municipality in the Central Bohemian Region. The thesis consists of two parts. The theoretical part describes honeybees, bee plants and their pollen- and nectar production ability as well as bee forage from early spring until late autumn so as to reflect the needs of pollinators as best as possible. The practical part uses pollen analysis to microscopically analyse the representation of pollen grains of plants in the honey produced by local bee colonies. Pollen analyses of honey from own bee colonies are compared with that from bee colonies belonging to neighbouring beekeepers.
Effect of grazing diversity on bee colony health status
ŠEBESTA, Tomáš
The Bachelor thesis aims at establishing the impact that diversity of bee forage has on the state of health of the bee colony. Honeybees are important for the life on this planet. The first part of the thesis presents a description of honeybees and of what is natural for, and indispensable to, their life. It presents plants that offer high- or low-quality pollen and nectar in our climate conditions during the year according to the phenological calendar, and also discusses changes in our landscape in the course of history. The second part focuses on substances that may help bees to fight against diseases and pests.
