This morning I gave the formerly queenless cell builder colony a careful examination. The queen cells were still there -- yah, so I moved them to a different cell builder colony. The population was, at least, double what it had been -- the native population of this hive were dark bees, now there were a large percentage of the Italian yellow bees. And, finally I saw the new queen, she hadn't begun laying yet, but appeared to be sizing up nicely -- with the completely fuzzy thorax of a recent virgin.
As Michael Bush mentioned, these are quite possibly AHB. If this is typical behavior for AHB, then, how can we expect to keep them out. They could take over anywhere they wished, and how would we even know? Since "hot" colonies are routinely requeened or destroyed, we may soon see calm AHB everywhere they wish to be.
Two years ago, I began requeening with Cordovan Italian, partially in an attempt to monitor the genetics of my bees. At least while the colonies queen continues to exhibit the golden Cordovan trait, and her workers do too, then there is most likely no AHB blood in them. It is said that the Cordovan trait can be bred into any strain/race of honeybee, but my hope if this happens (Cordovan gets bred into AHB), that better traits are preserved -vs- any poor AHB traits. Time will tell.
If I happen to create Cordovan AHB, then I hope, that they retain one good trait, that would be calmness, especially calmness on the combs.
