Well, I just got back from putting my grafted pure bred SMR larvae into finnishing off hives. It'll be interesting to see what happens. I'd like to keep diversity, but one sample of drone brood from my trusty rusty survival of the fittest local bees had an average 12 mites per larva. And the larvae looked very fat and smug. I wonder though, I got a letter like others of you from Dr. Harbo, and do you guys and gals think that the open mated daughters will also have a shorter life span than other bees? I'm wondering if I'll have to re-queen again in 6 months or so.
