I looked at the video that was cited. He mentions the Calderone drone trapping study. This took place 20 years ago at the Dyce Lab and I was a participant. Drone comb removal is very labor intensive and suffers from two other problems. 1) it can reduce mite build-up but it will not eliminate the need for fall treatment in our region.  2) in August it was difficult to get bees to raise drones at all. 

He also mentions Cuba and says that drone trapping reduces varroa infestations. Reports are that the bee populations of Cuba and also PR, have developed behavioral mite resistance. My view is that behavioral resistance develops in large unmanaged or semi-unmanaged populations. In a situation where the bees are constantly being moved and mixed, I don't see how it's possible.
