We found the buckfast bees tended to be quite a bit more "spirited" in their hive defense 7 or 8 years prior to the area becoming Africanized and I consider that a Buckfast Trait from our experiance. We did not consider the level of defensiveness to outweigh the value of their higher vigor. The all Americans gave us less performance in our operation than the Buckfast. Dennis VanEnglesdorp, PA state beekeeper, raved to me about the Canadian Buckfast when he was working at Dyce and I look forward to trying them in the future. Did I see a post somewhere about Buckfasts being bred in Missouri?
