Do you reckon they're AHB? (Given the percentage that were below ground? If so, how long do you figure they have been in the stump? Was there evidence they had been in a taller tree, but over time moved down as the upper part went away?
Would you be interested in sending me a dozen freshly dead bees and I could genotype the colony to get an idea of what percentage Africanized genetics?
I don't beleve they are any AHB in this colony. For one I have been working the hive without gear. they are very calm bees. the size cells they have are close to the 4.9mm. they moved into a stump that was ate out by termites. the cavity was only in the bottom of the Pine tree. The upper part of the stump was solid Fatlight. I have for starting the fireplace this next winter.
