Talking to a fellow commercial beek today and he asked if I was having any problems with my hives. He stated that he was having a higher then usual die out of hives from being queenless. The problem seems to be that if the queen dies, instead of building queen cells for new queens the bees are just dying off and not building queen cells. We are wondering if there is some genetic strain that has gotten into the bees that prevents this, maybe some anti-swarming genetic that someone was playing around with. Anyone else experiencing this? The majority of the queens are Kona but it could be anything. Also to note, there is not any unusual AFB or EFB going on and the hives that are not losing queens are exceptionally strong this year....never an easy answer.
