Abstract : The objective of this experiment was to explore the effects of dietary crude protein level on the quality of rearing queens for Apis cerana cerana.

Glass hives offer a close-up view of the bees at work, with the queen bee in each hive marked by a white dot.

S. and other countries, bees in massive numbers began to disappear over the winter. Beekeepers would lift the lid of a hive to find only the queen and a few stragglers, the worker bees gone.
