>Question for hard wood. How long does it take for an aging Queen to start rearing aggressive bees?
> I have always heard as the queen ages the bees become more aggressive, progressively. How true is this?
I think it is a combination of genetics and an aging queen, perhaps, but I have a lot of four year old queens and no aggressive bees.
>Is a queen from 3 states over considered local if the weather patterns are the same?
I think you view it as two levels of "local". One is that they have as hard of winters as you, this helps winter survival. The other is that they actually have the same flows as you, and this can vary in a few miles...
> It's good to bring in queens from different breeders from time to time trying to maintain genetic diversity.
I disagree. Unless you are insistent on buying all your queens, I would try to maintain local stock and not bring in outside stock.
