Bee Pastures and Pollination

Changed on: 13.08.2018

Nutritional Foundations of Bee Colonies

The availability of sufficient supplies of the appropriate nutrition (water, pollen, nectar, honeydew) is vital for the healthy and continuous development of bee colonies. Additional substances, such as propolis, are also needed.

Flowering plants that are visited by bees for feeding are referred to as bee pastures or nectar sources. The individual plant species are of varied significance for bees’ diets.
Thus, research projects on bee pastures make valuable contributions to biodiversity and provide alternatives to maize with the "energy plant" silphium.

GMO and Bees

Bees can come in contact with genetically modified plants and their derivative products in several ways:

  • Food sources (nectar, pollen) 
  • Feed for bees made of GMO plants (e.g. pollen substitutes based on GMO soymeal) or enzymes formed by GMO microorganisms (e.g. corn syrup).

The appropriate legal regulations in regards to tolerance levels and labelling for food and feed are in place.
