Abstract - Artificial queen cells with grafted young worker larvae of Apis cerana and Apis koschevnikovi were simultaneously introduced into queenless colonies of either A cerana and A koschevnikovi. All colonies preferred to rear conspecific larvae. The degree of this larval preference was different: A cerana colonies were more selective than A koschevnikovi colonies against alien larvae. In contrast, the A koschevnikovi colonies destroyed most of the introduced mature A cerana queen cells and killed all the queens that were able to emerge. A long term acceptance of alien queens occurred in A cerana colonies. The A koschevnikovi queens performed successful mating flights from A cerana colonies and the time of mating flights of these queens did not differ from A koschevnikovi queens flying from conspecific colonies. The mated A koschevnikovi queens laid eggs and the emerged bees were successfully reared by the A cerana worker bees. The A cerana host colonies were gradually transformed into A koschevnikovi colonies.
