That sounds like a great opportunity to spread the resistant parasites from hive to hive and region to region.
I doubt that there's any hope at all of controlling mites in free-roaming honeybees. I'd wager that we've done damage with overuse of miticides (which are insecticides, btw -- the article doesn't connect those dots) in a misguided attempt to control nature.

Probably the better solution here is to stop trying to do industrial farming of bees, and move to a system where local populations of pollinators are cultivated and maintained year round. But sure, RNAi is probably better than the chemicals they're using now.
