Impact of steroid hormone signals on
Cell Division, 2009 Metamorphosis of Drosophila involves proliferation, differentiation and death of larval tissues in order to form the adult fly. The major steroid hormone implicated in the larval-pupal transition and adult tissue modelling is ecdysone.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum
Insect Science, EarlyView.RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Novel functions of Ecdysone receptor B1 isoform during Drosophila oogenesis
, 2008 In Drosophila, ecdysone signaling is mediated by a heteromeric receptor composed of the Ecdysone Receptor protein (EcR) and the RXR homolog transcription factor Ultraspiracle (USP).

Function and Evolution of Nuclear Receptors in Environmental-Dependent Postembryonic Development
Frontiers in Cell and Developmental Biology, 2021 Nuclear receptors (NRs) fulfill key roles in the coordination of postembryonal developmental transitions in animal species. They control the metamorphosis and sexual maturation in virtually all animals and by that the two main environmental-dependent ...

Assessing Predator Activity on Clay Models in Response to Common Insecticides in Turfgrass
Entomologia Experimentalis et Applicata, EarlyView.Insecticides exhibited clear but time‐dependent effects on predatory activity, as reflected by impression types and density on clay models in turfgrass. Certain insecticides (bifenthrin, and in some cases acephate + imidacloprid, imidacloprid, chlorantraniliprole, and tetraniliprole) reduced total impressions shortly after application and again later ...

Ecdysone-mediated programmed cell death in Drosophila
, 2015 During Drosophila development, the steroid hormone ecdysone plays a key role in the transition from embryo into larva and then into pupa. It is during larval-pupal metamorphosis that extensive programmed cell death occurs to remove large obsolete larval ...

Insect Molecular Biology, EarlyView.Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Frontiers in Marine Science, 2021 C-type allatostatins (C-type ASTs) are a family of structurally related neuropeptides found in a wide range of insects and crustaceans. To date, the C-type allatostatin receptor in crustaceans has not been deorphaned, and little is known about its ...

Molecular characterisation of the salmon louse, Lepeophtheirus salmonis salmonis (Krøyer, 1837), ecdysone receptor with emphasis on functional studies of female reproduction [PDF]
, 2014 The salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae) is an important parasite in the salmon farming industry in the Northern Hemisphere causing annual losses of hundreds of millions of dollars (US) worldwide.

Ecdysone metabolism in the tick Ornithodoros moubata (Argasidae, Ixodoidea)
, 1982 The metabolism of injected [3H]ecdysone was studied in final-instar nymphs of Ornithodoros moubata (Murr.) at different stages of the moult cycle in the laboratory in Switzerland.
