Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

Vegetal residue‐based formulation of Trichoderma ossianense, a new indigenous vineyard species adapted to alkaline pH with potential biocontrol ability against Black‐foot disease pathogens

Pest Management Science, Volume 82, Issue 4, Page 2910-2924, April 2026.
The study identifies Trichoderma ossianense, was can be isolated from grapevine roots, is capable of growing at alkaline pH and controls black‐foot pathogens, highlighting the vegetal residue‐based formulations that preserve its viability. Abstract BACKGROUND Fungi of the Trichoderma genus are used in vineyards as biological control agents mainly ...

Chrysoperla externa (Neuroptera: Chrysopidae) as a Potential Biological Control Agent of Raoiella indica (Acari: Tenuipalpidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 335-342, April 2026.
First and third instar Chrysoperla externa showed efficient predatory capacity at low R. indica density, but second instar C. externa exhibits a density‐dependent predatory ability. The lacewing C. externa shows promise as a biocontrol agent for R. indica in coconut because it consumed 8362 R. indica females across all its larval instars.

Surveillance of ash trees under multiple threats: Integrating emerald ash borer and ash dieback dynamics with stakeholder behaviour

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Tree‐health policies must balance identifying likely entry points and deployment of traps, targeted information campaigns and surveillance subsidies for land managers. Our unique, cross‐disciplinary approach can be applied to other pest/pathogen systems to inform tree‐health plans and how to balance resources.
