I am looking for the best way to count as accurately as possible varroas on
sticky boards without counting each one individually.  In the context of a
breeding program aimed at developping the natural ability of the bee to
coexist with varroa, I will have to count the mites on around 300 sticky
board twice a year.  I know one can use a grid and count only a limited
number of sections and then multiply.  Has anyone done some stats on how
many section have to be counted to obtain a reasonable precision?  I have
noticed personnally that most of the time the mites are not evenly spread
over the surface of the board.  This makes it more complicated!
