Involvement in reproduction 6. Regulation of metabolic activities and general body functions 7. Regulation of behavior 8. Regulation of preprogrammed cell death 1. Regulation of molting 2. Determination of form at metamorphosis 3. Effects on polymorphism 4. Regulation of diapause Along with the nervous system, hormones provide the necessary communication between all the cells that constitute a multicellular animal Produced within an organism’s body by neuronal, neuroglandular or glandular centres Transported to their target tissues by haemolymph, often water-soluble Influence a remarkable variety of physiological processes, even though present in extremely small quantities INSECT HORMONES There are dozens of known insect hormones Best known system = “the Triumvirate” of Ecdysteroids 蜕皮激素 Juvenile hormones 保幼激素 Neurohormones (neuropeptides) 神经激素 They are integral to the growth and reproductive functions in insects Some insect hormones are used as pesticides BEST KNOWN HORMONES Endocrine Centers The hormones of the insect body are produced by neuronal, neuroglandular, or glandular centers Major hormonal centers include Brain (Neurosecretory cells 神经分泌细胞) Corpora cardiaca (sl. corpus car
