I have 3 hives from feral stock all are the same as the feral bees that i see in many gum trees around here, my friend has 10 hives all bred from very yellow Italian bees that are very gentle and do'nt need smoke. My bees like all the ferals in the area are a mixture of bees with 2 yellow bands and some say 20% with no yellow bands at all.
My friend breeds his own queens in his own yard by just takeing a nuke or 2 and raising new queens.
They have stayed the same this past 10 years and do'nt seem to have mixed with the local "roughies"
Is there an evidance that queens usually mate with drones from their own yards?
