>>We are talking the real world here and most bees are suffering from

And it is the (commercial?) beekeepers job to make valiant attempts to avoid
this.

It can occur anywhere when the pollen is of low nutritional value.  Bob has
suggested that maize pollen is not much good.  In fact it is less than
useless, but it is not alone in that.

It amazes me that the USA industry has not done the research on their
pollens.   The five secrets of beekeeping- pollen, pollen, pollen, young
queens, shift on time.
