Abstract: | Unilateral extirpation of the wing discs was performed on mid- and late-third instar larvae of Sarcophaga peregrina to investigate the regulation capacities of the thoracic discs. Out of 636 operated larvae, 175 became adult and all of them exhibited hemithoracic structures, lacking any adult structures in the operated side, which were normally produced from a wing disc. These findings suggest that the wing disc does not possess the capacity of bicentric regulation to produce the thoracic structures of the opposite side. |
