Mature larvae and prepupae of Ephestia were divided into four age groups ( A 1– A 4). In each age group two operations were carried out alone or in combination: a. extirpation of one or both hind wing imaginal disks; b. ligation behind the lead (removal of the neurosecretory cells of the brain) or between meso‐ and metathorax (removal of brain and prothoracic glands). Pupation and regeneration of the extirpated wings were observed. Consequently, 36 different experiments were carried out in all, demonstrating varying results at different stages but ultimately confirming the conclusion from previous experiments that during the time of regeneration the activities of the brain and of the prothoracic glands are suppressed.
