The ability to generate physiologically synchronous groups of insects is vital to the performance of investigations designed to test insect responses to intrinsic and extrinsic stimuli. During a given instar, the silverleaf whitefly, Bemisia argentifolii,

Phytochemical investigation of the fronds of Microsorum membranifolium resulted in the isolation of a new phytoecdysteroid, E-2-deoxy-20-hydroxyecdysone 3-[4-(1-b-D-glucopyranosyl)]-caffeate (1), together with two known phytoecdysteroids, E-2-deoxy-20 ...

BmFoxO Gene Regulation of the Cell Cycle Induced by 20-Hydroxyecdysone in BmN-SWU1 Cells. [PDF]
Ecdysteroid titer determines the state of the cell cycle in silkworm (Bombyxmori) metamorphosis. However, the mechanism of this process is unclear. In this study, we demonstrated that the BmFoxO gene participates in the regulation of the cell cycle ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Heterokairic Genes and the Eco‐Evo‐Devo of Timing
Heterokairic genes as the bridge (Heterokairic Pathways?): Heterokairic genes are heterochronic regulators whose activity is modulated by environmental conditions. External cues (e.g., temperature, nutrition, oxygen, density: yellow box) are sensed (yellow arrows) and converted into endocrine and metabolic signals (purple box and arrow into fish's ...

Phosphorylation of ribosomal protein S6, induced when the fat body of Sarcophaga peregrina (flesh-fly) larvae was incubated in vitro in the presence of 32P, was found to be suppressed by juvenile hormone.

Depression of Synaptic Efficacy at Intermolt in Crayfish Neuromuscular Junctions by 20-Hydroxyecdysone, a Molting Hormone [PDF]
Cooper, Robin L. and Marvin E. Ruffner. Depression of synaptic efficacy at intermolt in crayfish neuromuscular junctions by 20-hydroxyecdysone, a molting hormone. J. Neurophysiol. 79: 1931–1941, 1998. This report demonstrates that ecdysteroids can reduce

A homologue of the ecdysone receptor has been identified and shown to be responsive to 20- hydroxyecdysone in Brugia malayi. However, the role of this master regulator of insect development has not been delineated in filarial nematodes.

During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support
