Contrôle endocrine et neuroendocrine de la mue de puberté chez les mâles de Sphaeroma serratum (Fabricius, 1787) (Crustacea,Isopoda, Flabellifera)

In the males of Sphaeroma serratum, the course of the puberty molt is controled by the Y organs, the brain, and perhaps the antennary glands. Y organs initiate and follow up proecdysis (probably by participating in production of ecdysterone, the physiological rate of which is high during D₀ and D₁) and secrete an ecdysis factor. After the puberty molt, they degenerate and the rate of ecdysterone reduces to zero. The brain initiates proecdysis, probably by secreting a Y-stimulating neurohormone (YSH), and in the control of ecdysis; it could stop in C₄ the molting cycle of adult males. The antennary glands control the mineral water metabolism and could act during the ecdysis, paticularly during the physiological ecdysis. These controls and their connections are discussed and a synthetic diagram is proposed.
