Juvenile hormone counteracts the bHLH-PAS transcription factors MET and GCE to prevent caspase-dependent programmed cell death in Drosophila [PDF]

open access: yes, 2009
Juvenile hormone (JH) regulates many developmental and physiological events in insects, but its molecular mechanism remains conjectural.

Non‐chemical stresses do not strongly induce male offspring in Daphnia magna ascertained using the short‐term juvenile hormone activity screening assay

open access: yesJournal of Applied Toxicology, Volume 44, Issue 12, Page 1914-1923, December 2024.
Abstract Juvenile hormone (JH), together with ecdysone, regulates molting, metamorphosis, growth, and reproduction in arthropods. The effects of its analogs used as insecticides on nontarget species are of concern. Since JH and JH analogs (JHAs) induce male offspring in daphnids, which generally reproduce by parthenogenesis, short‐term JH activity ...

Control of corpus allatum activity in the adult Colorado potato beetle [PDF]

open access: yes, 1983
Control of corpus allatum activity was investigated in adult Leptinotarsa decemlineata (Say) under various external conditions. Gland activity was measured in vitro utilizing the incorporation of ( 14 C)-methyl-Methionine into juvenile hormone III by ...

Giovanni Pontano hears the street soundscape of Naples

open access: yesRenaissance Studies, Volume 38, Issue 4, Page 519-540, September 2024.
Abstract Giovanni Pontano’s dialogue Antonius can be read almost as a thick description of the soundscape of a Neapolitan street in the mid‐ to late‐15th century, complete with public announcements, street performers, domestic arguments, workers’ banter, charms and spells, processions, errand boys, bells, clocks, cockerels, and much more.

A comparative study of metabolic effects of the corpus allatum in two adult Coleoptera, in relation to diapause [PDF]

open access: yes, 1965
Two problems were studied: a) Whether a lower titre of the corpus allatum hormone had a different influence on the tissues of an adult insect with a diapause mechanism than on those of one without a diapause.

Transcriptome Analysis of Drosophila melanogaster Third Instar Larval Ring Glands Points to Novel Functions and Uncovers a Cytochrome p450 Required for Development

open access: yesG3: Genes, Genomes, Genetics, 2017
In Drosophila melanogaster larvae, the ring gland (RG) is a control center that orchestrates major developmental transitions. It is a composite organ, consisting of the prothoracic gland, the corpus allatum, and the corpora cardiaca, each of which ...

Deciphering the cellular heterogeneity of the insect brain with single‐cell RNA sequencing

open access: yesInsect Science, Volume 31, Issue 2, Page 314-327, April 2024.
Single‐cell RNA sequencing (scRNA‐seq) has emerged in the past decade and profoundly accelerated our understanding of brain complexity. scRNA‐seq has a higher resolution than bulk RNA‐seq, which enables novel cell type classification, dynamic trajectory construction, and gene regulatory network identification.

Changes in Size of the Corpus Allatum in a Polymorphic Insect [PDF]

open access: yesNature, 1965
IN order to gain some insight into the part played by the endocrine system in determining form in a polymorphic insect, an investigation was undertaken of changes in volume of the corpus allatum in virginoparous alate and apterous forms of the cabbage aphis, Brevicoryne brassicae (L.).
