A Comparative Test of the Pollen Substitutes

Scientific Beekeeping     By Randy Oliver 

The growth and health of honey bee colonies is primarily dependent upon the availability of high-quality pollen. Pollen and its fermented form, beebread, is the colony’s primary source of protein, lipids, vitamins, minerals, and sterols [1].

When there is a dearth of quality pollen, colonies suffer [2]. Broodrearing comes to a halt and the nurses may cannibalize eggs and larvae. Colonies stop growing or go downhill. Protein-starved colonies are unable to hold their own against parasites and pathogens; diseases set in. Inadequate protein nutrition in late summer and fall leads to poor wintering and colonies unable to make grade for almonds.

To mitigate the above problems during times of pollen dearth, beekeepers...
