Misdiagnosis of CCD is more than easy without microscopic study..
I had a beekeeper to call me an he stated that he had CCD. 80 % of his
hives, about 45 in total had died during winter. Very few dead bees left.
Clean frames, no visble sings of pest or desease.
I sugested taking bee samples to a bee lab. The few remaining bees were
heavily infested with acarapis mites. So that was the case. I would not
recommend anyone stating CCD without looking the remaining bees with a
microscope for heavy nosema or acarapis.
