I don't think we can compare pandas to bees to well but it's something to think about.
We have'nt for the most part had any new stock brought in since the pilgrims brought them here, then you add on the fact that for years Queen breeders have selected for low swarming , where has the vigor gone??
In my opinion not to search the world over for stock and obtain it ,we have weakened our bees. It's not like we (the USA) have kept out all of the bad pests from the rest of the world.
