HORMONAL CONTROL OF RESPIRATORY METABOLISM DURING GROWTH, REPRODUCTION, AND DIAPAUSE IN MALE ADULTS OF PYRRHOCORIS APTERUS L. (HEMIPTERA)

The respiratory metabolism of adult Pyrrhocoris males is very low when compared with that of females, and it is independent of hormones. Allatectomy, cardicallatectomy, castration and diapause have no profound effect on the rate of respiration in the adult male, unlike the situation in the adult female. Indeed, males respire at about the same rate as females deprived of endocrine glands. The sexual dimorphism in respiration and hormone action is correlated with the differences in growth, digestion and reproduction. It is shown that the hormones influence the over-all metabolism indirectly by regulating the morphology and physiological activity of specific tissues.
