    Summary
    The removal of small hive beetle [=SHB] eggs and larvae was studied in queenright and recently queenless Cape honeybee, Apis mellifera capensis, colonies over a range of phenotypes. The overall removal efficiency was not influenced by phenotypes or queenstate, because all introduced eggs and larvae were removed within 24 hours. Queenless colonies removed them merely slower than queenright ones. The latter ones rejected up to 300 larvae within one hour. However, colonies undergoing preparation for absconding did not completely remove SHB offspring, suggesting that removal efficiency was reduced. Since even small and recently queenless colonies effectively removed immature SHB, and no differences in the overall efficiency was found compared to A. m. scutellata we conclude that this defense behavior is well developed in African honeybees
