The hormones of endocrine system act as chemical messengers that regulate different body functions such as growth, metabolism, and reproduction. Crustacean Hormones have multifunctional nature: Ecdysteroids may serve: During embryonic development as morphogens or promote protective membranes From larval to adult life they then function as molting hormones. Ecdysteroids The steroid arthropod molting hormone was first isolated from insects and it was called ecdysone. invertebrates : miriapoda . Such a system may range, at its simplest, from the neurosecretory, involving one or more centres in the nervous system, to the complex array of glands found in the human endocrine system. Therefore, it is likely that the various endocrine systems in invertebrates are subject to modulation by an unforeseeable number of exogenous compounds.

These effects led to a break-down of local oyster production with marked economic consequences. Neurohormones are released from the infracerebral complex into the coelomic fluid through which they travel to their targets. In males, it causes the testes to produce a hormone that regulates sperm production.Adrenocorticotropic hormone (ACTH) stimulates the adrenal gland to produce steroid hormones. Their endocrine system mainly contains the neuroendocrine components and possesses very few true glands. Endocrine glands arise during development for all three embryologic tissue layers (endoderm, mesoderm, ectoderm). 1. ADH controls water balance in the body and blood pressure. EVIDENCE FOR ENDOCRINE DISRUPTION IN INVERTEBRATES The issue of ED in invertebrates has found an increasing scientific interest although only a limited number of confirmed cases have been reported. Department of Pharmacology The class Insectaare the most diverse group of organisms on the Earth.Molting, also called ecdysis refers to the process of shedding the old cuticle during the developmental stages of insects from one instar stage to the next. This gonadotropic peptide hormone (a hormone that has the gonads as its target organ) is stored in a typical neurohemal organ until its release is stimulated. kc.

The well-developed crustaceans have a neurohemal organ, called the sinus gland. Insect Growth Regulators Insect growth regulators (IGRs) represent third generation insecticides and were developed to intentionally interact with the hormonal system of these arthropods, acting as ecdysone agonists, antagonists or juvenile hormone analogs Ecdysteroid antagonists prevent normal diapause induction, and induce an early termination of diapause or a precocious metamorphosis, while juvenile hormone (JH) analogs, interfere with egg hatching, larval development, larval-pupal molts, and ecdysis and reduce the fertility and longevity of exposed specimens.
