Fields of Application of the Red Mason Bee (Osmia rufa L.)

Osmia rufa is a wild bee endemic in Middle Europe. It pollinates a wide spectrum of miscellaneous plant species.
The high pollination activity by polylectic foraging results in multi-purpose fields of application:

Main field

Field of application Examples Notes
Seed- and
Fruit Production

Assurance of seedset to
conserve plant species and
breeding of new varieties

Seed production,
hybrid breeding programmes
Suitability for
isolation chambers and

Increase of fruit yield
in orcharding

Strawberry production,
blueberry production,
apple- and cherry cultivation

(bee hotels)
for settling at teaching location

Advantages of Osmia rufa compared to social insects (e.g. honey bees or bumble bees):

1. Effective application possible not only in the field but also in large and small greenhouses;
2. Higher pollination activity of a single bee;
3. Short distances for foraging restrict the spread of diseases (e.g. of fire blight);
4. Cocoons under cold storage (4C) available to application at every time from March to September
5. Red mason bees do not sting!
