摘要: Feeding conditions and energy status, communicated by the parallel complementary Amino acid sensing, TOR insulin pathways, determine go or no-go for progeny reproduction in insects. In adult, addition to genetic cell specific gender imprint, Juvenile Hormone ecdysteroids, main hormonal actors during pre-adult development, are re-used as regulators of reproduction. Molecular evidences indicate functional threshold values either hormone being decisive proceeding arresting production yolky eggs. Depending upon species, 20-OH-ecdysone acts positive regulator whereas other usually becomes a negative balancer. Accordingly, neurosecretory hormones, including gonadotropins gonadostatins regulate their release interaction. Metabolic regulators, corpora cardiaca derived Adipokinetic ovarian hormones Trypsin Modulating Oostatic factors interfere affecting availability use circulating amino building blocks. Importantly, males when needed fertilization, sperm, deliver endocrine Sex-peptide Ovulin even 2O-OH-ecdysone that affect both female reproductive physiology post-mating behavior.
