What  effect does this double queen system have on the expansion of  
varroa  in the hive.



I don't do it often enough to have a handle on this; however if the first  
brood that the old, artificially swarmed, queen produces is destroyed as soon as 
 it is sealed and the same is done with that of the daughter (the bees 
attending  the daughter will be flying from a different entrance to Mum's) that 
should mop  up lots of mites, unless the mites make their way from one brood nest 
to the  other.  That might be an experiment worth trying next season with a 
couple  of matched hives, using one as a control.
