A Review of Native Wild Bee Nutritional Health

Abstract EN

Declines in wild and managed bee species richness and abundances have been observed throughout Europe and North America in recent decades.

These declines have led to questions regarding pollination of wild and cultivated plants.

In response to these concerns, efforts towards the conservation of pollinators have been initiated.

Part of this conservation effort should be to provide the basic nutritional needs for bees.

Nutrition plays one of the most important roles in bee growth, development, and reproduction.

There is a large body of information regarding honey bee nutrition, whereas we lack nutritional information on native wild bees.

Our knowledge of bumble bee nutritional needs has increased since the introduction of commercial rearing and sale of certain bumble bee species; however, there is still a lack of basic nutritional guidelines such as minimum dietary needs of proteins, amino acids, lipids, and sterols.

The large difference in physiology and life history between honey bees and North American wild bees suggests that their nutritional requirements could be quite different.
