I've found it can vary significantly depending on the nectar flow or if you are feeding the cell builder.  In general you probably don't get much wax reuse in queen cells, but at times during the year the queen cells are significantly darker indicating that wax reuse was likely.

We shouldn't forget the other half of puzzle.  Drones are often raised in the old damaged comb that should have been melted down years ago and we don't know how susceptible they may be to most of these chemicals.   We already know that coumaphos, fluvalinate, and Apilife VAR have a significant negative effect on viability and/or quantity of sperm.   ( http://scholar.lib.vt.edu/theses/available/etd-08162007-092313/ )  Could this have a noticeable impact on the queens reared both during and for several weeks after a spring varroa treatment?   I believe they've also shown that comb with acceptable levels of contamination by coumaphos also causes similar drone problems.
