This text covers the development physiology of silkworms, including growth equilibrium by genes and by environment.
Contents
Growth equilibrium by environment; growth equilibrium by genes; endocrine organs of insects; changes in diapause due to injection of synthetic juvenile hormone and ecdysterone; changes in the levels of juvenile hormone and ecdysone in different instar stages; functions of the brain that affect activity of the corpus allatum; control of growth by the brain corpus allatum system; functions of genes that govern the quantitative features and the environment; actual application of hormones; conclusion - development balance. Supplement: studies on the release of brain hormone from the corpora allata; the significance of establishing the role of the brain-corpus allatum - prothoracic gland; the significance of hormones in practical applications; methods used in experimentation and observation.
