	Note that this is a rule of thumb only.  Temperature and species
may require different counting intervals.  One way to be sure you're
getting virgins is to keep the culture bottles that you hold the alleged
virgins around for a few days after you use them.  If you see any larvae
running around, the flies weren't all virgins, or you put a male in there.
