Phytochemical Profiling and Evaluation of Antibacterial, Anticancer, Anti‐inflammatory, and Wound‐Healing Activities of Endophytic Fungi Isolated From Atalantia racemosa

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
ABSTRACT Endophytic fungi are recognized as prolific sources of structurally diverse secondary metabolites with significant pharmaceutical potential. In the present study, endophytic fungi were isolated from healthy tissues of Atalantia racemosa (Rutaceae), an ethnomedicinal plant traditionally used for respiratory disorders and blood purification.

Pharmacological Properties and Function of the PxOctβ3 Octopamine Receptor in Plutella xylostella (L.)

Insects, 2022
The diamondback moth (Plutella xylostella) is one of the most destructive lepidopteran pests of cruciferous vegetables, and insights into regulation of its physiological processes contribute towards the development of new pesticides against it.

Acute Exposure to Traces of Chlorantraniliprole Does Not Alter Antipredator Behaviour in Wild Crickets

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We tested whether acute, residue‐level exposure to a widely used insecticide alters antipredator behaviour in wild field crickets. Using a field‐based behavioural assay, we found no detectable effects on escape speed or re‐emergence latency over the days following exposure.

Octopamine receptors in Drosophila larvae: expression, development, and behavior

Frontiers in Molecular Neuroscience
Octopamine is involved in a variety of physiological and behavioral mechanisms throughout the Drosophila melanogaster life cycle. Octopaminergic neurons in both the central and the peripheral nervous system target a multitude of neurons and even non ...

Peptidoglycan-dependent NF-κB activation in a small subset of brain octopaminergic neurons controls female oviposition

eLife, 2019
When facing microbes, animals engage in behaviors that lower the impact of the infection. We previously demonstrated that internal sensing of bacterial peptidoglycan reduces Drosophila female oviposition via NF-κB pathway activation in some neurons (Kurz

Small molecules as arthropod kinin receptor antagonists, feeding modulators, or novel mosquitocidal agents

Pest Management Science, Volume 82, Issue 7, Page 6842-6863, July 2026.
A two‐pronged screen of small molecules – (1) on recombinant kinin receptor and (2) through topical application – identifies kinin receptor antagonists, feeding behavior modulators, and new mosquitocidal molecules. Abstract BACKGROUND Aedes aegypti and Culex quinquefasciatus mosquitoes are primary vectors for numerous human and animal pathogens and ...

Octopamine neuromodulation regulates Gr32a-linked aggression and courtship pathways in Drosophila males. [PDF]

PLoS Genetics, 2014
Chemosensory pheromonal information regulates aggression and reproduction in many species, but how pheromonal signals are transduced to reliably produce behavior is not well understood.

Regulation and modulation of biogenic amine neurotransmission in Drosophila and Caenorhabditis elegans

Frontiers in Physiology, 2023
Neurotransmitters are crucial for the relay of signals between neurons and their target. Monoamine neurotransmitters dopamine (DA), serotonin (5-HT), and histamine are found in both invertebrates and mammals and are known to control key physiological ...

Octopamine Neurons in Lobsters: Location, Morphology, Release of Octopamine and Possible Physiological Role

Cold Spring Harbor Symposia on Quantitative Biology, 1976
Octopamine cells are found along second thoracic roots, where they serve as neurosecretory neurons capable of releasing octopamine at two distinct points: one into the hemolymph immediately before it enters the gills; one into the hemolymph immediately after it leaves the gills. The octopamine cells receive a cholinergic synaptic input. We presume that
