There are a few feedback mechanisms that have been suggested/researched
(e.g., Camazine), plus Rob Page's work with the different degree of the
high Vg pollen-collecting lines.

In queenless colonies I also see a diminution of pollen foragers, yet also
commonly see the bottom frames packed with polished pollen.
