Diet acts on sexual behavior development in a male moth

Insect Science, Volume 32, Issue 4, Page 1439-1452, August 2025.
Drastic changes are observed during sexual maturation characterized by the reproductive system development concomitantly to the sexual behavior ontogenesis. These modifications are under the control of internal and external factors such as food. Knowing that sexual maturation requires considerable energetic investment, diet has been shown to affect ...

Mode of Action of Farnesol, the “Noble Unknown” in Particular in Ca2+ Homeostasis, and Its Juvenile Hormone-Esters in Evolutionary Retrospect

Frontiers in Neuroscience, 2019
Farnesol, the sesquiterpenoid precursor of insect juvenile hormones (JH) that itself has JH activity, existed already long before animals and their hormones came into being.

Developmental transcriptomes predict adult social behaviours in the socially flexible sweat bee, Lasioglossum baleicum

Molecular Ecology, Volume 34, Issue 15, August 2025.
Abstract Natural variation can provide important insights into the genetic and environmental factors that shape social behaviour and its evolution. The sweat bee, Lasioglossum baleicum, is a socially flexible bee capable of producing both solitary and eusocial nests.

Neuropeptide Ecdysis‐Triggering Hormone and Its Receptor Mediate the Fecundity Improvement of ‘Candidatus Liberibacter Asiaticus’‐Infected Diaphorina citri Females and CLas Proliferation

Advanced Science, Volume 12, Issue 18, May 15, 2025.
In CLas‐infected D. citri, CLas lowers 20E levels initially, relieving the suppression of ETH release. The subsequent increase in ETH levels upregulates its receptor DcETHR and activates the JH signaling pathway. The signaling cascade of 20E‐ETH/ETHR‐JH along with miR‐210, targeting DcETHR, boost female fecundity in CLas+ D.

Culex quinquefasciatus Mosquitoes Exposed to a Juvenile Hormone Analog may Take a Bloodmeal While Gravid

Archives of Insect Biochemistry and Physiology, Volume 119, Issue 1, May 2025.
We applied s‐hydroprene, a juvenile hormone analog (JHA), to gravid female mosquitoes that have naturally ceased JH production. We found that gravid females exposed to JHAs blood fed in a dose dependent manner and this behavior could be induced through simulated environmental exposure.

Gene cloning, recombinant expression, and bioassay of an allatotropin in Spodoptera litura Fabricius (Lepidoptera: Noctuidae)

Journal of Basic and Applied Zoology, 2021
Background Allatotropin, a neuropeptide found in several invertebrates indirectly regulates vitellogenesis by stimulating juvenile hormone biosynthesis by the corpora allata.

The moulting arthropod: a complete genetic toolkit review

Biological Reviews, Volume 99, Issue 6, Page 2338-2375, December 2024.
ABSTRACT Exoskeletons are a defining character of all arthropods that provide physical support for their segmented bodies and appendages as well as protection from the environment and predation. This ubiquitous yet evolutionarily variable feature has been instrumental in facilitating the adoption of a variety of lifestyles and the exploitation of ...

Egfr signaling promotes juvenile hormone biosynthesis in the German cockroach

BMC Biology, 2022
Background In insects, an interplay between the activities of distinct hormones, such as juvenile hormone (JH) and 20-hydroxyecdysone (20E), regulates the progression through numerous life history hallmarks.

Histone Deacetylase 3 Is Involved in Maintaining Queen Hallmarks of a Termite

Molecular Ecology, Volume 33, Issue 22, November 2024.
ABSTRACT The role of epigenetics in regulating caste polyphenism in social insects has been debated. Here, we tested the importance of histone de/acetylation processes for the maintenance of queen hallmarks like a high fecundity and a long lifespan.

A new look at the nature of insect juvenile hormone with particular reference to studies carried out in the Czech Republic

European Journal of Entomology, 2015
This article is a comprehensive summary of the 50-year history of physiological investigations in the Czech Republic into the mode of action of the corpus allatum hormone (CAH) in insects, which is commonly known as the juvenile hormone (JH). During this
