I believe one of the members of the list located in Africa has previously
stated that bees deal with SHB in the native range by a combination of
absconding (due to migration of african honey bees across long distances)
and hive death due to infiltration by the Cape bee.

Published reports in the ABJ show that honey bees will propolise the SHB
into small cages and then feed them (as prisoners), rather than killing them
off.  Seems an odd behavior.
