I just finished requeening 52 hives today, and I noticed quite a few cases of two queens per hive, even though the average hive is just 4 frames of brood or so. I've seen it on occasion like many of the rest of you have, but not like this year. The first time was last Fall when a hive in some Raspberries I was pollinating savagely attacked me, stinging me through the suit and following my car to the gate which I estimate a quarter mile away. It reminded me of the worst of the feral, never medicated or domesticated Scuts I had in Africa. I took some in later to the ag commissioner, and they were confirmed AHB. I went back later and killed the queen and reduced the amount of brood. A week and a half later I went back to requeen it, but there was a big, mature queen there and the hive was full of eggs and larva. This last operation where I requeened there were about ten percent double queens, but I saw no link to aggressive behavior. Just more that usual. I wonder if that particular characteristic isn't necessarily linked to aggression. -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
