▪ Abstract Environmental and hormonal regulators of diapause have been reasonably well
defined, but our understanding of the molecular regulation of diapause remains in its …

Insect diapause is a dynamic process consisting of several successive phases. The
conception and naming of the phases is unsettled and, sometimes, ambiguous in the …

▪ Abstract Agrochemical research over the last two decades has resulted in the discovery of
chemically novel insecticides that mimic the action of the two insect growth and …

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 …

▪ Abstract We discuss a framework for studying the evolution of morphology in insects, based
on the concepts of “phenotypic plasticity” and “reaction norms.” We illustrate this approach …

Ecdysteroids are widely used as inducers for gene-switch systems based on insect
ecdysteroid receptors and genes of interest placed under the control of ecdysteroid …

Various animals across the tree of life express some form of programmed dormancy (eg
hibernation, diapause) to maximize fitness in highly seasonal environments. The integrated …

Concurrent with our expanding knowledge of the general field of endocrinology has come
the revelation that what was accepted as a central dogma is no longer true. In the case of …

It is well known that there is no necessary one-to-one relationship between the genetic
makeup of an organism-its genotype-and the various characters and properties that …

The molting process in arthropods is regulated by steroid hormones acting via nuclear
receptor proteins. The most common molting hormone is the ecdysteroid, 20 …
