| Abstract: | The neuroendocrine factors synthetized by various regions of the nervous system and which have inhibiting or stimulating effects can control the male and female physiology of malacostraca via sexual hormones and moulting hormone. There are between decapods and peracarids functional homologies but some differences can be noticed as to the localization of these antagonistic neurosecretory systems. The functioning of these systems is regulated by external factors such as the photoperiod and the temperature. The interactions between these different neurohormones, the sexual hormones and the moulting hormone are discussed. |
