Another reference to wildbee vs honey bee pollination is
 
C.W. Westerkamp, Honeybees are poor pollinators--Why?
Pl. Syst. Evol. 177:71-75 (1991)...I quote the abstract:
 
"Contrary to most other bee species honeybees are highly eusocial and
hold extremely long-lived societies.  Their all-season activities
force them to use whatever plants available and prevent any specific
adaptations--in the flowers, in honeybees, and in all competing bees.
This flexible behaviour in flowers has been a pre condition for
perennial colony life.  But as bees eavde becoming contaminated with
by pollen their visits often do not result in pollination.  Honeybee
monocultures thus must be avoided by all means."
 
The English could be cleaned up a bit, but the point gets across.
