One other point to note about small cell bees is this,(this only in theroy, so don't anyone go off). The host-perisite relationship usually is not as detrimental to the host as has been the verrona mite-honeybee relationship. As I understand it, verrona normally only infects drone brood, which would allow for hive survial, and continued host supply for the mite. But because our commercial honeybees are larger than the ones in the wild, the mites can't tell the difference between worker cells and drone cells, and so infects both. Which kills the host, as well as the mite who nolonger has a host to live off. Survialal of the host = survailal of the perisite, and vise versa. As I said this is only theroy at this point but it does make sense. Just some thoughts.
