The adrenal gland releases too little of the hormone cortisol and sometimes, aldosterone. Crustaceans also have a hormone very similar to the JH III of insects, known as methyl farnesoate (MF) The hormone is synthesized by the mandibular organs, which are endocrine glands close to the mandibles. 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. It uses glands to regulate these processes which release hormones. As You know: Invertebrates are animals without a backbone. Hormonal System of Invertebrates.
