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. > Keith Malone wrote: > > What do honey bees do to combat SHB in it's place of origin, they immobilize > the beetle by propolising it.
