Hi All.
    A relationship of logistics.  My apologies.  It seems that I may
given cause for confusion by not going into details about this
expression.  My career in the militay leads me astray sometimes,
thinking in terms of logistics.  My resoning (logistically) is that one
(beekeepers) does not break open queen cells routinely to inspect for
Varroa.  There are not that many queen cells available to break open,
except during swarming season at which time the cell may not even have a
queen in it.  But the most important reson is the based on the fact that
because queens have a shorter incubation period, the nursing bees
(bearing the mites) will visit the queens fewer times and because queen
cells are capped sooner than worker bees and much sooner than drone
cells.  In my reasoning, logistically, developing queen larvae are less
likely to be invaded by mites, (theory).
     In practice, it is worth keeping in mind, and as stated previously,
I will dedicate time to that effort, especially during swarming season
when I will be removing unwanted queen cells.  I believe this subject is
of particular interest to queen breeders, and their reply to this thread
should be interesting.
Sincerely.
