Adipose tissue of Drosophila melanogaster. II. The effect of the adult internal environment on growth, protein deposition, and histolysis in the larval fat body

Abstract

AbstractTransplantation experiments show that growth, protein deposition, and histolysis in the larval fat body of Drosophila melanogaster are controlled by a secretion of the larval ring gland. The internal environment of the normal adult female generally mimics the effect of the ring gland. However, the female environment induces more growth but less histolysis than the ring gland. The internal environment of the adult male stimulates only growth in the fat body. Transplantation studies with normal, castrated, and mutant adults indicate that the ovary is important in the stimulation of growth, protein deposition, and histolysis. The corpus allatum‐corpus cardiacum complex of adult D. virilis females will induce growth, protein deposition, and histolysis in the larval fat body of D. melanogaster.
