Novel Ecdysteroids from Serratula wolffii

The Scientific World Journal, 2012
Two new and one known ecdysteroids were identified in the methanolic extract of the roots of Serratula wolffii. The new compounds isolated were ponasterone A-22-apioside (1) and 3-epi-shidasterone (3), together with the known 3-epi-22-deoxy-20 ...

Heterokairic Genes and the Eco‐Evo‐Devo of Timing

Evolution &Development, Volume 28, Issue 2, June 2026.
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 ...

Non‐Invaginated Wing Primordia in Holometabolous Insects: First Report From Mecoptera

Evolution &Development, Volume 28, Issue 2, June 2026.
We investigated wing primordium development in the scorpionfly Mavropanorpa japonica and present the first detailed histological description of a late‐forming, non‐invaginated wing primordium lacking a morphologically distinct peripodial epithelium in Mecoptera.

Practical uses for ecdysteroids in mammals including humans: an update

Journal of Insect Science, 2003
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-response elements. We review here these systems, which are currently mainly used in vitro

Biotechnological potential of aquatic plant ecdysteroids

Romanian Journal of Horticulture
Ecdysteroids are polyhydroxylated sterols initially identified in insects but later reported in numerous terrestrial plants, including Ajuga, Rhaponticum, and Cyanotis. These metabolites display diverse biological properties such as anabolic, adaptogenic,

Evaluation of physiological and molecular tools to assess ovarian stages in the black tiger prawn (Penaeus monodon)

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Advancing knowledge of the molecular mechanisms governing vitellogenesis and spawning in the black tiger prawn, Penaeus monodon, requires an efficient method for identifying ovarian stages. Several physiological and molecular tools have been employed to define these stages in laboratory studies.

Task Performance and Queen Presence Influence the Brain Transcriptome in a Bumble Bee (Bombus terrestris) With a Flexible Division of Labour System

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Division of labour in reproduction and in task performance are two hallmarks of insect societies. Bumble bees and honey bees are both classified as eusocial, but differ in the social organization of their colonies and in the hormonal regulation of division of labour.

Body Size Trade‐Offs Underpin Reproductive Success and Thermal Stress Tolerance in an Invasive Pest, the Small Hive Beetle

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Body size differences have widely been observed in adult small hive beetles (Aethina tumida Murray, SHBs), an invasive pest of honey bee colonies. We hypothesized that parental body size influences reproductive performance, progeny fitness, and stress tolerance in SHBs.

From flower buds to bolls: how cotton reproductive structures shape boll weevil development, reproduction and survival

Pest Management Science, Volume 82, Issue 5, Page 4576-4584, May 2026.
Female boll weevils feeding on flower buds promote reproduction regardless of their immature diet, whereas boll feeding increases lipid reserves and lifespan, revealing a nutrition‐driven trade‐off that sustains survival and reproduction in tropical boll weevil populations.

Investigating Low‐Temperature Stress Responses in Crustacea Aquatic Species Through Comparative Transcriptomics

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Crustaceans, such as shrimp and crabs, are pivotal to global aquaculture, yet their productivity is severely impacted by low‐temperature stress. This study employs comparative transcriptomic and genomic analyses to elucidate the molecular mechanisms underlying crustacean responses to cold stress across five economically significant species ...
