I checked my 3 Russian hives a couple weeks ago and all was good - plenty of honey - pollen stores were good and the bees where flying...
Today my plan was to split hives starting with the Russians - they're located 10 miles from my main bee yard. When I arrived there was no activity from two hives. These two hives were empty of bees - but there was honey and pollen left behind in one of the hives. The third hive ( all these hives are side by side ) was busting with bees. There were no dead bees in or around the two quite hives. Whatever happen I suspect it happened with the bees leaving all at once with none left behind..... The third hive must have robbed the hive that was empty of honey - there was wax cappings on the bottom board where they had taken the honey - the drawn comb was clean almost polished. The other hive still had plenty of honey ( super was 80% full ) and pollen but also not one bee to be found. I guess the strong hive not found it yet or didn't have any where to put the honey.
I went ahead and did the split on the strong hive - I had to add a drawn comb super after the split - the winter super was full on honey - bees covering the inner cover. it looked like something you'd see in June or July...not the last week of Feb. in SC.. I'll try to give these Russians a fair shot but I haven't had very good luck with them.. I requeened one of my Italian hives last spring after a swarm, I did it with a Russian queen. I checked the hive today - I found the marked bred queen but the hive never grew past one brood box in size. This hive is sitting in line with 9 Italian hives that I started splitting today also. These 9 were more than ready to split - bringing loads of pollen in and had large stores of honey. I split 3 of the 9 Italians today - I'll finish them tomorrow then move to my last group of 5 Italian hives caught from swarms last yr..
Like I said I had just checked those hives a couple weeks ago and now it's like the bees just vanished for no reason.... I hope this isn't a trait of Russians to abandon the hive for no reason and the 1 brood box queen, I don't have a clue. Any ideas.....
Russians start slow, being a cold weather bee by origin. They will take of in a month or so and by June you shouldn't be able to tell which was which by measure of activity and population. Everything else being equal a softball size cluster of Russians will build to the same size hive as a basketball size cluster of Italians by Mid-May. Slower start, higher top speed.
