Attack density negatively affects reproductive success but not fecundity or offspring body size in a bark beetle

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 1, Page 76-81, February 2026.
Neither gallery length nor eggs per female varied significantly with attack density, suggesting P. proximus adults disregard galleries constructed by conspecifics and continue to lay eggs irrespective of attack density. Number of adult offspring per female decreased significantly as attack density increased, indicating that intraspecific competition ...

Repellent Effects of Host Essential Oils and Limited Effects of Host Length on Tree‐Killing Bark Beetle Attacks

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 1, Page 37-44, January 2026.
This study demonstrated that the host essential oil significantly reduced Polygraphus proximus Blandford (Coleoptera: Scolytinae) attack density, but the density did not differ significantly among logs of various lengths of Abies sachalinensis. Our study suggests that host essential oils can perform as repellents against conifer‐infesting bark beetles.

Evolutionary History and Rhizosphere Microbial Community Composition in Domesticated Hops (Humulus lupulus L.)

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Humulus lupulus L., commonly known as hop, is a perennial crop grown worldwide and is well known for its pharmacological, commercial, and most importantly brewing applications. For hundreds of years, hop has undergone intense artificial selection, with over 250 cultivated varieties being developed worldwide, all displaying differences in key ...

Semiochemical applications for managing the grey field slug (Deroceras reticulatum Müller), a major pest of arable crops

open access: yesPest Management Science, Volume 81, Issue 11, Page 7288-7301, November 2025.
Trends in semiochemical research highlight promising attractants and repellents for ‘push–pull’ pest control strategies of the grey field slug. Extracts from plants, predators, entomopathogenic fungi, and essential oils demonstrate potential in modifying grey field slug behaviour, inducing avoidance, antifeeding responses, or mortality, offering ...
