The influence of hormones on the lipid profile in the fat body of insects [PDF]

Invertebrate Survival Journal, 2015
Peptide hormones play a special role in the neuroendocrine systems of insects and affect a number of physiological processes related to their development, reproduction and behavior.

Further characterization of locust low density lipophorin induced by adipokinetic hormone

Journal of Lipid Research, 1991
This study was designed to resolve basic questions concerning the nature of low density lipophorin (LDLp) which is induced by adipokinetic hormone (AKH).

Sensitivity of gypsy moth neurosecretory neurons to acute thermal stress [PDF]

, 2013
In gypsy moth caterpillars exposed to a temperature of 35°C (for 1, 12 and 24 h and caterpillars that were exposed to elevated temperature for 12 h and were allowed to recover for 12 h at 23°C), changes in the brain protein profiles and morphometric ...

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.

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 ...

Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...

Methoprene modifies adipokinetic hormone characteristics in the firebug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

European Journal of Entomology, 2010
In the present study the hypothesis that there is a feedback between juvenile hormone and adipokinetic hormones (AKHs) was investigated by topical application of the juvenoid methoprene on 9-day-old adult males of the firebug Pyrrhocoris apterus.

Thermosensory TRPV Heterotetramers Drive Seasonal Polyphenism: Molecular Basis of CcIav/CcNan‐PKCα‐AKH/AKHR Signaling in Pear Psyllid Morph Transition

Advanced Science, Volume 12, Issue 45, December 4, 2025.
At 2 5 °C, thermal activation initiates: i) CcIav/CcNan heterotetramer assembly → Ca2⁺ influx; ii) CcPKCα phosphorylation → AKH signaling potentiation; iii) CcAKH1 binding to membrane‐localized CcAKHR → energy mobilization (lipid catabolism/glycogenolysis) and vitellogenin transport via follicular patency; iv) Oocyte maturation → summer‐form nymph ...

Functional characterization of hypertrehalosemic hormone receptor in relation to hemolymph trehalose and to oxidative stress in the cockroach Blattella germanica

Frontiers in Endocrinology, 2012
Hypertrehalosemic hormone (HTH) is a peptide hormone that belongs to the AKH/RPCH (adipokinetic hormone/red pigment concentrating hormone) family, which exerts pleiotropic actions related to catabolic reaction and stress response.
