title: Fertile diploid drones in africanized honeybees, Apis mellifera adansonii.
abstract: 59 diploid drones of Apis mellifera adansonii, 12-37 days old, were tested for the presence of semen after provoked ejaculation; 13 drones ejaculated semen enough to be used in an instrumental insemination, but only three on them (5%) furnished 1 mm3 of semen. The problems referring to the attainment of descendants from the 2n drones are briefly discussed.
