Randy speaks soberly of the effect that selecting for a few traits and requeening colonies en-mass with these hybrids from closely mated lines has had on the diversity of the gene pool (both from the selection on the breeding end, and in the introduction of homogenous hybrid stock into apiaries).  He promotes an old (and almost never talked about) practice of requeening by making a split to ward off swarming (making sure eggs, honey and brood are present within the split).  Simply wait two months, and recombine the two colonies.  In most cases, you will end up with a new queen (and in those that you don’t, you are likely better off with the old one).
