The ecdysone receptor signalling regulates microvilli formation in follicular epithelial cells. [PDF]

open access: yesCell Mol Life Sci, 2016
Epithelial morphogenesis contributes greatly to the development and homeostasis of the organs and body parts. Here, we analysed the consequences of impaired ecdysone receptor (EcR) signalling in the Drosophila follicular epithelium. Besides governing cell growth, the three EcR isoforms act redundantly in controlling follicle cell positioning ...

Lethal and Sublethal Effects of Methoxyfenozide on the Development, Survival and Reproduction on of the Fall Armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) [PDF]

open access: yes, 2011
The lethal and sublethal effects of the ecdysone agonist methoxyfenozide on the fall armyworm, Spodoptera frugiperda (J. E. Smith), were investigated by feeding a methoxyfenozide-treated diet to fifth instars until pupation in doses corresponding to the ...

Computational Binding Study Hints at Ecdysone 20-Mono-Oxygenase as the Hitherto Unknown Target for Ring C-Seco Limonoid-Type Insecticides

open access: yesMolecules
The insecticidal property of ring C-seco limonoids has been discovered empirically and the target protein identified, but, to date, the molecular mechanism of action has not been described at the atomic scale.

In vitro cultures of pupal integumental explants to bioassay insect growth regulators with ecdysteroid activity for ecdysteroid amounts and cuticle secretion [PDF]

open access: yes, 2007
The present study evaluated the in vitro bioassay with pupal integumental explants of the mealworm Tenebrio molitor to test the activity of two types of insect growth regulators (IGRs) with ecdysteroidal action. We assessed the imidazole derivative KK-42,

The ecdysteroidome of Drosophila: influence of diet and development [PDF]

open access: yes, 2015
Ecdysteroids are the hormones regulating development, physiology and fertility in arthropods, which synthesize them exclusively from dietary sterols. But how dietary sterol diversity influences the ecdysteroid profile, how animals ensure the production ...

Functional investigations of the Ecdysone Receptor and production of ecdysone in the salmon louse (Lepeophtheirus salmonis)

open access: green, 2016
The salmon louse Lepeophtheirus salmonis is a marine ectoparasitic copepod naturally infecting salmonid fishes in the Northern hemisphere. At present, salmon louse infections are the most severe disease problem in the salmon farming industry causing significant economical losses.
