I also found hives with no queen and no emergency cells in the spring. About 10% of my queens were lost later in the season without any reason I could see. They were mostly newly mated queens that had been laying for some weeks that suddenly were gone. In at least one hive the bees had started making emergency cells before the queen stopped laying. I don't have varroa yet, so no medication has been done. There is very little spraying going on, and the farmers are well aware of the risk of killing bees. There were good weather with a good honey flow and plenty of pollen available. I have never seen anything like it before, don't belive it's bad mating or poorly reared queens. But something is affecting the bees. Anyone else with similar experience? -- Regards P-O Gustafsson, Sweden [log in to unmask] http://www.kuai.se/~beeman/
