Characterising Spectral Sensitivity and the Role of Sunlight Intensity in Japanese Beetle (Popillia japonica) Surveillance and Monitoring (Coleoptera: Scarabaeidae)

open access: yesJournal of Applied Entomology, Volume 150, Issue 1, Page 46-55, February 2026.
ABSTRACT The Japanese beetle (JB) Popillia japonica (Coleoptera: Scarabaeidae) has been a significant invasive pest for over a century in North America. Several studies have reported that plants under direct sunlight are preferred and trap colour affects the number of beetles captured, indicating that visual stimuli influence JB behaviour.

Halogenated Organic Compounds: A Massive Halogen Reservoir and an Intriguing Component of the Marine Dissolved Organic Matter Pool

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Biogeochemical reactions produce volatile halocarbons and semi‐ to nonvolatile dissolved organic halogens (DOX) in marine systems. The former has a large influence on atmospheric chemistry, but little is known about DOX. Here, we present depth profiles of dissolved organic bromine (DOBr) and ‐iodine (DOI) isolated from the Central North ...
