I can't help with this request, but would like to make a point. Some one
asked why our border was closed to bees from down South? This is the reason,
to try prevent AHB genes from polluting our gene pool, whether deliberately
or accidently. If you're  the slightest bit nervous about contamination by
AHB, my advice, buy your queens from up north, we know we are pure!!!
