Molecular Insights and Repellent Efficacy of the Essential Oil and Major Compounds From Piper cyrtopodon (Miq.) C.DC (Piperaceae) Against Aedes aegypti (Linnaeus, 1762) (Culicidae)

open access: yesArchiv der Pharmazie, Volume 359, Issue 6, June 2026.
The essential oil and major compounds from Piper cyrtopodon exhibit potent, long‐lasting repellent activity against Aedes aegypti mosquitoes, combined with low cytotoxicity and favorable molecular docking interactions with odorant‐binding proteins. These findings highlight its potential for the development of alternative products for bite prevention ...

Sensory Morphology of Geodorcus helmsi (Coleoptera: Lucanidae) and its Relevance to the Conservation of New Zealand Stag Beetles

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Insects use sensilla to detect chemical and physical stimuli, mediating behaviours such as mate finding, foraging and mechanosensory responses. The distribution and density of sensilla can be examined using scanning electron microscopy. Investigating these structures can help elucidate rarely observed behaviours (e.g. mate finding and foraging).

Systematics of the New World Rostrate Genus Metaxyphloeus Thomas, 1984 (Coleoptera: Laemophloeidae): Morphological Evidence for Monophyly Supporting a Broader Generic Concept

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT A morphology‐based MP analysis is undertaken to test the monophyly of the lined flat bark beetle genus Metaxyphloeus Thomas, 1984, as well as to hypothesize its intra‐ and intergeneric evolutionary relationships. Based on the results of the present work, Metaxyphloeus, as currently composed, is hypothesized as a monophyletic assemblage of ...

Fighting for Chemicals: Pharmacophagy‐Induced Contest Behaviour and Its Molecular Signatures in a Sawfly

open access: yesMolecular Ecology, Volume 35, Issue 8, April 2026.
ABSTRACT Elucidating the multifaceted effects of plant metabolites sequestered by animals from plants for non‐nutritional purposes, known as pharmacophagy, is fundamental to understanding the evolution of acquired chemical defences. Some herbivorous species do not only take up plant metabolites from plants but also engage in antagonistic interactions ...

Predatory behaviour of some Central European pselaphine beetles (Coleoptera: Staphylinidae: Pselaphinae) with descriptions of relevant morphological features of their heads

open access: yesEuropean Journal of Entomology, 2008
The Pselaphinae is a large subfamily of staphylinid beetles with a characteristic habitus and small body size. Detailed morphological and behavioural studies on these beetles are scarce.
