Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Pathogenicity of Beauveria bassiana strains isolated from Ostrinia nubilalis Hbn. (Lepidopte­ra: Pyralidae) to original host and to ladybirds (Coleoptera: Coccinelidae)

open access: yesPlant Protection Science, 1999
B. bassiana strains isolated from 0. nubilalis were tested against the larvae of 0. nubilalis and coccinellid beetles in laboratory conditions (25°C). The first dead 0. nubilalis larvae were observed 48 hours after the application.

Sexual calling behaviour, and the effects of immediate mating history and consexual presence in the seven‐spot ladybird, Coccinella septempunctata

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 5, Page 393-402, May 2025.
To attract mates, several coleopteran taxa release volatile sex pheromones via a behaviour termed calling. We studied a postulated calling behaviour in the seven‐spot ladybird Coccinella septempunctata L. for the first time. We also investigated the effects of immediate mating history and the presence of conspecifics on calling behaviour.

Spray‐induced gene silencing to control plant pathogenic fungi: A step‐by‐step guide

open access: yesJournal of Integrative Plant Biology, Volume 67, Issue 3, Page 801-825, March 2025.
Spray‐induced gene silencing is an innovative, eco‐friendly technology for controlling plant fungal diseases by applying RNA molecules that silence key fungal genes via RNA interference. This guide explores how to develop safe and effective formulations based on current knowledge, aiming to improve their efficacy under real‐world conditions.
