Bark beetle protein elicitors trigger biphasic immune responses in Norway spruce seedlings

This study shows bark beetle protein elicitors induce a biphasic immune response in Norway spruce seedlings, with early signaling and later defense protein accumulation, mirroring responses in mature trees.

Pioneer bark beetle attacks induce multifaceted localized defense responses in Norway spruce

This study investigates Norway spruce defense responses to bark beetle attacks using multi-omics approaches, revealing hormone-induced gene expression and metabolic changes that deter beetle colonization.

Efficacy of Mating Disruption Treatments Against Spongy Moth (Lymantria dispar dispar) Applied Using Unmanned Aerial Vehicles

This study evaluates UAV-applied SPLAT(R) GM-Organic for spongy moth control, finding it reduces trap catches by >90% for 10 weeks and maintains 28-67% reduction one year later, comparable to fixed-wing treatments.

Combined phylogenetic and geographic data can predict plant-pest interactions with high accuracy

The paper builds a Bayesian model to predict plant-pest interactions using phylogenetic and geographic data, achieving high accuracy in identifying host risks for Agrilus beetles.

An integrative field and modelling study of the bottom-up, top-down and indirect effects of native species on invasive insects and their biological control : the case of the worldwide chestnut tree pest, Dryocosmus kuriphilus, in the French Eastern Pyrenees

The paper investigates indirect effects of native species on an invasive insect and its biological control in chestnut trees using ecological and statistical methods.

Temperature impacts on mating and oviposition of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae)

This study examines how temperature affects the reproduction of emerald ash borer beetles, finding that temperatures above 21°C are necessary for successful egg hatching.

Unravelling the bottom-up and top-down control of a worldwide chestnut tree pest invader through integrative ecological genomics

The paper identifies the relative impacts of host trees, resistance pathways, and natural enemies on the invasion potential of a chestnut tree pest using ecological and genomic analyses.

A novel integrated framework to identify and characterize regional-scale pest insect dispersal

The paper develops an integrated framework combining isotope geolocation, ecological data, and atmospheric modeling to trace regional-scale pest insect dispersal, demonstrating long-distance dispersal of spruce budworm across 400 km.

Climate change has already reshaped North American forest pest dynamics: Insights from multidecadal process-based modelling

This study uses process-based climate models to show climate change has already shifted the distribution and increased the climatic suitability of North American forest pests.

Factors Influencing Emerald Ash Borer Ecological Interactions

The paper analyzes ecological interactions of emerald ash borer beetles using DNA metabarcoding, finding that collection date and life stage best predict interaction detection.

Growth variation of an ambrosia fungus on different tree species indicates host specialization

This study examines the growth of the ambrosia fungus Dryadomyces montetyi on different tree species, finding it performs best on angiosperm hosts like oak.

Unlocking plant health survey data: an approach to quantify the sensitivity and specificity of visual inspections

This paper quantifies the sensitivity and specificity of visual plant health surveys using citizen scientists and Bayesian modeling to estimate these metrics without a gold-standard dataset.

Size-dependent behavioral and antennal responses to doses of (+)-isopinocamphone and 1,8-cineole mixed with pheromone: a potential host selection strategy in female Ips typographus L.

This study shows that larger female Ips typographus are more attracted to (+)-isopinocamphone and have larger antennal clubs, while smaller females show less repulsion to 1,8-cineole despite smaller antennae, suggesting size-dependent olfactory processing.

Intra- and interspecific variations in flight performance of oak-associated Agrilinae (Coleoptera: Buprestidae) using computerised flight mills

This study evaluates flight performance variability among oak-associated Agrilinae beetles, finding interspecific differences and limited average dispersal capacities.

Progress in Developing a Bark Beetle Identification Tool

This paper introduces a MaxViT-based model for bark beetle genus identification from images, achieving high F1 scores and serving as a foundation for future tools in forest management and ecology.

Recent climate change strongly impacted the population dynamic of a North American insect pest species

This study shows climate change has caused a northward shift in spruce budworm populations and altered their phenology and reproduction rates across North America.

The distribution of the hemlock woolly adelgid in Canada.

This paper maps the distribution of the hemlock woolly adelgid in Canada, identifying native and invasive populations and estimating spread rates in Nova Scotia.

Eruptive insect outbreaks from endemic populations under climate change

The paper presents a mechanistic model of mountain pine beetle population dynamics, showing how climate change can shift parameters to eliminate endemic equilibria and trigger outbreaks.

Tree diversity reduces pathogen damage in temperate forests: a systematic review and meta-analysis

This study conducts a systematic review and meta-analysis showing that tree species diversity reduces pathogen damage in temperate forests, with neighbour identity playing a key role.

A highly contiguous genome assembly of a major forest pest, the Eurasian spruce bark beetle Ips typographus

The paper presents a high-quality genome assembly of the Eurasian spruce bark beetle, revealing gene families related to plant cell wall degradation and providing resources for studying its evolutionary biology and pest control.
