Farnesol and farnesal dehydrogenase(s) in corpora allata of the tobacco hornworm moth, Manduca sexta.

Journal of Lipid Research, 1983
The metabolism of [3H]farnesol was studied in cell-free preparations of corpora allata from the tobacco hornworm, Manduca sexta, to assess the role of this presumed biosynthetic precursor of juvenile hormone (JH) III.

Neuropeptide receptor transcriptome reveals unidentified neuroendocrine pathways. [PDF]

PLoS ONE, 2008
Neuropeptides are an important class of molecules involved in diverse aspects of metazoan development and homeostasis. Insects are ideal model systems to investigate neuropeptide functions, and the major focus of insect neuropeptide research in the last ...

Farnesol-like endogenous sesquiterpenoids in vertebrates: the probable but overlooked functional "inbrome" anti-aging counterpart of juvenile hormone of insects?

Frontiers in Endocrinology, 2015
Literature on the question whether the juvenile stage of vertebrates is hormonally regulated is scarce. It seems to be intuitively assumed that this stage of development is automated, and does not require any specific hormone(s).

Juvenile Hormone Is Required in Adult Males for Drosophila Courtship. [PDF]

PLoS ONE, 2016
Juvenile Hormone (JH) has a prominent role in the regulation of insect development. Much less is known about its roles in adults, although functions in reproductive maturation have been described.

Approaches and Tools to Study the Roles of Juvenile Hormones in Controlling Insect Biology

Insects, 2020
The juvenile hormones (JHs) are a group of sesquiterpenoids synthesized by the corpora allata. They play critical roles during insect development and reproduction.

Genetic dissection of stress-induced reproductive arrest in Drosophila melanogaster females. [PDF]

PLoS Genetics, 2018
By genetic manipulations, we study the roles played by insulin-producing cells (IPCs) in the brain and their target, the corpora allata (CA), for reproductive dormancy in female Drosophila melanogaster, which is induced by exposing them to a combination ...

Antibodies Against the Clock Proteins Period and Cryptochrome Reveal the Neuronal Organization of the Circadian Clock in the Pea Aphid

Frontiers in Physiology, 2021
Circadian clocks prepare the organism to cyclic environmental changes in light, temperature, or food availability. Here, we characterized the master clock in the brain of a strongly photoperiodic insect, the aphid Acyrthosiphon pisum ...

Neurohormones in insect stress: A review [PDF]

Archives of Biological Sciences, 2006
The neurohormones are the master regulators of all life processes in insects and they create a strategy of stress protecting events. Neurohormones are synthesized mainly in insect brain neurosecretory neurons.

THE RELATION BETWEEN CORPORA ALLATA SECRETION AND PROTEIN SYNTHESIS IN MALE SEXUAL ACCESSORY GLANDS OF Spodoptera littoralis (Boisd.) [PDF]

Journal of Plant Protection and Pathology, 2011
The relation between juvenile hormone (JH) released from the corpora allata of the Spodoptera  littoralis  male moths and protein synthesis in the sexual accessory glands (SAGs) of the reproductive system had been studied in the present work.
