Resumo

— Honey bee colonies (Apis mellifera carnica), infested with Varroa jacobsoni were de- queened and divided into 2 subunits.Each pair of subunits were requeened with an inseminated A m capensis and A m carnica queen.The development of the mite population was monitored by de- termining the number of mites in samples of brood, and worker bees, and the number of dead mites on the bottom board of the hive.The mite population showed a restricted development in A m ca- pensis colonies.Varroa mites were found at surprisingly low frequencies on adult worker bees of the Cape honeybee.A more efficient grooming activity, in combination with the short post-capping stage of the brood, may be the central factors for the restricted development of the mite population in A m capensis.
