Development Physiology of Silkworms

About this book

Examines moultinism and diapause in silkworms, with chapters on growth equilibrium by environment and by genes, endocrine organs of insects, changes in diapause due to injection of synthetic juvenile hormone and ecdysterone, and changes in levels of juvenile hormone and ecdysone in different instar stages. Other subjects include functions of the brain that affect activity of the corpus allatum, and control of growth by the brain-corpus allatum complex.

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.
