Effect of Hormones on the Respiration of Body Fragments of Adult Pyrrhocoris apterus L. (Hemiptera)

Nature volume 205, pages 416–417 (1965)Cite this article

Abstract

PREVIOUS investigations of normal adult female Pyrrhocoris have demonstrated cyclic changes in the rate of oxygen consumption closely correlated with cycles of ovarian development and oviposition. These cycles disappear in females deprived of corpus allatum; when the corpora cardiaca were also removed, the absolute level of oxygen consumption decreased to low and steady levels similar to those encountered in normal adult males or diapaushig adult females. The hormones seem to affect the total metabolism indirectly. For example, the activation hormone (AH) secreted by the brain neurosecretory cells—corpora cardiaca system—is a trophic factor which stimulates metabolic activity in tissues engaged in digestion and food utilization. The corpus allatum hormone (CAH) is thought to regulate metabolic activity in reproductive system1–3.
