that  caged bees fed unfermented pollen 


What was the source of 'unfermented pollen'? Did the experimenters collect  
it direct from the plants or was it pollen pellets collected by bees?  If  so 
it would probably have already been innoculated with digestive juices from  the 
salivary glands of the bees as they moisten pollen with regurgitated nectar  
during the collection process.
