Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Regulatory mechanisms of reproduction in locusts and grasshoppers

New Plant Protection, Volume 3, Issue 1, March 2026.
Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

Structure-Activity Studies on the Hypertrehalosemic Hormone II of the Stick Insect Carausius morosus (Phasmatodea): Carbohydrate-Mobilization and Cardio-Stimulatory Activities

Frontiers in Physiology, 2020
The corpora cardiaca of the Indian stick insect, Carausius morosus, synthesize two decapeptide neuropeptides of the adipokinetic hormone (AKH) family, both of which can increase the trehalose levels in the hemolymph when the stick insect is ligated ...

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐

Inter-organ metabolic feedback via BCAA catabolism regulates glucagon-like hormone secretion in Drosophila

Nature Communications
Metabolic homeostasis regulated by nutrient-responsive endocrine hormones is essential for organismal survival. In insects, lipid and carbohydrate mobilization is controlled by adipokinetic hormone (Akh), a glucagon-like peptide secreted from ...

Biological impact, oxidative stress and adipokinetic hormone activities of Agrotis ipsilon in response to bioinsecticides

Plant Protection Science, 2022
The use of biological control products enhances the reduction of harmful pressures on the environment caused by the use of conventional pesticides. Therefore, this study aims to evaluate the toxicity of eight bioinsecticides on the black cutworm Agrotis ...

In vitro study of the action of adipokinetic hormone in locusts.

Journal of Lipid Research, 1989
The in vitro study was performed in order to demonstrate the structural changes of lipophorin induced in vivo by the injection of adipokinetic hormone (AKH) into adult locusts.

Characterization of Triacylglycerol Dynamics and Lipid Metabolism in the Beetle Tribolium castaneum

Archives of Insect Biochemistry and Physiology, Volume 120, Issue 3, November 2025.
Tribolium castaneum larvae accumulate triacylglycerol (TAG) during development, while adults rapidly deplete reserves post‐emergence. Under starvation, beetles prioritize protein catabolism over lipid mobilization, despite increased expression of lipolysis genes, revealing stage‐specific metabolic adaptations in this model insect.

Insight Into Mosquito GnRH-Related Neuropeptide Receptor Specificity Revealed Through Analysis of Naturally Occurring and Synthetic Analogs of This Neuropeptide Family

Frontiers in Endocrinology, 2019
Adipokinetic hormone (AKH), corazonin (CRZ), and the AKH/CRZ-related peptide (ACP) are neuropeptides considered homologous to the vertebrate gonadotropin-releasing hormone (GnRH).

Imbalanced Hemolymph Lipid Levels Affect Feeding Motivation in the Two-Spotted Cricket, Gryllus bimaculatus. [PDF]

PLoS ONE, 2016
Insect feeding behavior is regulated by many intrinsic factors, including hemolymph nutrient levels. Adipokinetic hormone (AKH) is a peptide factor that modulates hemolymph nutrient levels and regulates the nutritional state of insects by triggering the ...
