I collected about fifty or more crawling bees from the front of the *each*
five infected hives, froze them overnight, and counted the mites, under a
microscope at school, and I found about three to ten mites in each sample;

The above might be a primative method to see if varroa is in the hive but
incorrect for  determining levels of infestation as used by researchers and
the USDA.

You went to a whole lot more work than needed Yoon.

Simply catch around 300 bees in a jar from THE BROOD NEST and spray starting
fluid in the jar. Roll and count the varroa on the side of the jar. Easily
visable with the naked eye.

You only need the microscope for tracheal mites (and I only use the
microscope to back up my field opinion done with a 16 power glass).

Did you check for a tracheal mite infestation while sitting at the
microscope?

All the above is in the archives.
