I don't understand the question.

Varroa mites do not need to interbreed to reproduce.  They only interbreed 
AFAIK when two foundresses or more happen to enter a cell with a pupa which 
survives, uncapped, to emergence.  In that case, any male offspring can mate 
with any of the females which subsequently mature enough, forming a mixed 
family.

Otherwise, it's all in the family and the inbred offspring are as viable 
AFAIK as the offspring of interbreeding.
