▪ 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 …

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 …

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

The ecdysone receptor is a heterodimer of the two nuclear receptors EcR and ultraspiracle
(USP). We have identified the regions of Drosophila EcR and USP responsible for …

Using the Drosophila melanogaster ecdysone receptor (DmEcR) BI cDNA clone, we isolated
three genomic clones for EcR from the tobacco hornworm, Manduca sexta. Subsequent …

Mating causes dramatic changes in female physiology, behaviour, and immunity in many
insects, inducing oogenesis, oviposition, and refractoriness to further mating. Females from …

The developing ovariole of the silkmoth Bombyx mori represents an excellent model for
studies on the changes that occur in gene expression during the execution of long-term …

Nineteen canonical and two Knirps-like family nuclear receptors (NRs) were identified in the
genome of Tribolium castaneum. The current study was conducted to determine the function …

Publisher Summary This chapter examines the information gathered about the ecdysteroid
receptor at three levels and provides brief descriptions and references for the tools used to …

Our studies of the Bombyx mori ecdysone receptor (BE) revealed that, unlike the Drosophila
melanogaster ecdysone receptor (DE), treatment of BE with the ecdysone agonist …
