The neuroendocrine stress-response in insects: the history of the development of the concept

open access: yesВавиловский журнал генетики и селекции, 2017
The neuroendocrine stress-response is an effective defense mechanism against adverse influences of various nature. This reaction is universal and appears in response to stimuli that are unusual not just for living and habitat of the species, but also for

The insect somatostatin pathway gates vitellogenesis progression during reproductive maturation and the post-mating response

open access: yesNature Communications, 2022
In mammals, somatostatin plays a role in preventing the release of sex hormones before puberty begins. A Drosophila study uncovered the process by which insect somatostatin controls ovarian development in response to developmental and mating signals.

Characterization of the swede midge, Contarinia nasturtii, first instar larval salivary gland transcriptome

open access: yesCurrent Research in Insect Science, 2023
Proteins in saliva of gall-forming insect larvae govern insect-host plant interactions. Contarinia nasturtii, the swede midge, is a pest of brassicaceous vegetables (cabbage, cauliflower, broccoli) and canola.

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

open access: yesFrontiers 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.

Special Types of Pesticides

open access: yesEDIS, 2005
This guide discusses some unique materials that are used as pesticides. Some types of pesticides do not belong to any specific chemical groups. Some of these are synthetically manufactured; some occur naturally in the environment, and others are ...

Intraluminal Farnesol and Farnesal in the Mealworm's Alimentary Canal: An Unusual Storage Site Uncovering Hidden Eukaryote Ca2+-Homeostasis-Dependent “Golgicrine” Activities

open access: yesFrontiers in Endocrinology, 2019
Farnesol, the sesquiterpenoid precursor of the six presently known insect juvenile hormones (JHs) was for the first time chemically identified in 1961, not in JH synthesizing glands or whole body extracts, but in excrements of the mealworm Tenebrio ...

Hormones, neuroblasts and the adult insect [PDF]

open access: yes, 1994
Insect neurogenesis has been subjected to extensive study and as a result is regarded as being well understood. It is, therefore, all the more surprising when a fundamentally novel aspects of the process is uncovered.

Full-length transcriptome and targeted metabolome analyses provide insights into defense mechanisms of Malus sieversii against Agrilus mali [PDF]

open access: yesPeerJ, 2020
Malus sieversii is the wild progenitor for many cultivars of domesticated apple and an important germplasm resource for breeding. However, this valuable species faces a significant threat in the areas north of the Tianshan Mountains in China, by the ...

Inducible Expression of Several Drosophila melanogaster Genes Encoding Juvenile Hormone Binding Proteins by a Plant Diterpene Secondary Metabolite, Methyl Lucidone

open access: yesInsects, 2022
Juvenile hormones prevent molting and metamorphosis in the juvenile stages of insects. There are multiple genes encoding a conserved juvenile hormone binding protein (JHBP) domain in a single insect species.
