A neuroendocrine feedback mechanism in the insect moulting cycle

Abstract

THE principles of neuroendocrine integration and regulation developed by the Scharrers1,2 are central to current concepts of the regulation of the hypothalamo–hypophyseal system and are applicable to all neurosecretory systems. The importance of these principles in the regulation of the analogous system in insects (the protocephalic corpus cardiacum–allatum system) has, however, been little studied. Here I illustrate certain general functional parallels in the regulation of the vertebrate and insect systems by reference to work on the regulation of the neurosecretory pathway controlling moulting in Rhodnius prolixus.
