The steroid hormone ecdysone is the central regulator of insect developmental transitions.
Recent new advances in our understanding of ecdysone action have relied heavily on the …

Phenotypic plasticity is the primitive character state for most if not all traits. Insofar as
developmental and physiological processes obey the laws of chemistry and physics, they …

Employing the clear, student-friendly style that made previous editions so popular, Insect
Physiology and Biochemistry, Fourth Edition presents an engaging and authoritative guide …

The mechanisms that control the sizes of a body and its many parts remain among the great
puzzles in developmental biology. Why do animals grow to a species‐specific body size …

In insects juvenile hormone (JH) regulates both metamorphosis and reproduction. This
lecture focuses on our current understanding of JH action at the molecular level in both of …

Publisher Summary This chapter discusses the ecdysone receptors and their biological
actions. It also summarizes the insect endocrinology and the roles of these steroids in the …

Publisher Summary This chapter describes the premetamorphic actions and general
consideration of cellular and molecular actions of juvenile hormone (JH). The chapter …

Nuclear receptors are ancient ligand-regulated transcription factors that control key
metabolic and developmental pathways. The fruitfly Drosophila melanogaster has only 18 …

▪ Abstract This review explores the roles of ecdysone and juvenile hormone (JH) in the
evolution of complete metamorphosis and how metamorphosis, in turn, has impacted …

Precise neural circuit assembly is achieved by initial overproduction of neurons and
synapses, followed by refinement through elimination of exuberant neurons and synapses …
