Managing bees in areas with AHB presence is certainly not as simple as it was before their arrival. My personal approach is to keep a close eye on the temperament of my hives and re-queen with queens of known genetics any that are consistently aggressive when conditions (weather, nectar flow, time of day, etc.) are optimal for them to not be so. I also keep plenty of drone frames in hives headed by a queen of known genetics in an attempt to reduce the influence of AHB drones. At this point, I have not had any of my hives require more drastic action. At least half of my hives are of feral origin and so far none have proved to be unmanageable with this approach. Re-queening with Cordovan queens is another option that allows you to have a more visual indicator of when the hive supersedes and could be at risk.

The AHB problem is an ongoing battle and until such point that those who regulate beekeeping in our state/country acquiesce to them, we must continue to "fight the fight". I think that it is abundantly clear that we will never be able to eradicate them, but it does appear to me that there has been some measure of success at mitigating their influence.
