>>Some of our hives had so few mites in the sugar... by monitoring the
natural mite fall, I can determine if the infestation of mites are growing or shrinking.

I did not get when you apply the powder sugar.  One limitation or possible misinterpretation stems from the fact that most mites will be [capped?] in brood cells during the brood-rearing season.  As I understand it, sugar dislodges only mites on the adult bees on the frames which is still beneficial.
