Rear and manage populations of solitary bees
A replicated controlled laboratory experiment at the University of Bologna, Italy, found that 408 European orchard bees Osmia cornuta reared on pollen-based artificial diets showed high larval mortality (76-100%; Ladurner et al. 1999). The 331 control bees allowed to consume the pollen lump provided by their mother had lower mortality rates (4-32%). These authors suggest this is because female O. cornuta bees add something, perhaps an enzyme, to the pollen they provide for their larvae.
