If  numbers are kept low, what is the likelihood of them   interbreeding?

I don't understand the question.

Varroa mites do  not need to interbreed to reproduce.


Exactly!  It therefore follows that if numbers are kept low, by  whatever 
means, the chances of selection of resistance by mixing genes is  slight; 
however that still leaves selection for resistance by mutation.
