I'm glad this subject came up again.  A post on May 8 bothered me,
and I intended to reply, but it slipped my mind.

Perhaps it is the way it was written and I am misreading the claim,
"I have developed the powdery sugar dusting as a physical control
of Varroa mite."  The powdery sugar detection for Varroa mites should
be attributed to Paula Macedo, a University of Nebraska Graduate Student
working with Marion Ellis.  See:
