Kernel-Based Early Detection of Forest Bark Beetle Attack Using Vegetation Indices Time Series of Sentinel-2

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The European spruce bark beetle (Ips typographus L.) is a biotic disturbance that devastates forest environmental services, and its activities are exacerbated due to climate change. Accordingly, researchers seek workflows using remote sensing imagery for

Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

Insect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.

Species diversity and host plant associations of ambrosia beetles in Southeast Asian forests of Laos and Vietnam revealed by DNA barcoding

Insect Conservation and Diversity, EarlyView.
Integrative DNA barcoding of ambrosia beetles and host plants revealed 27 beetle species across 16 genera and extensive, previously undocumented host plant diversity in Laos and Vietnam. Host specificity varied widely among ambrosia beetles, with Xylosandrus crassiusculus emerging as a dominant generalist associated with 19 host species from 12 plant ...

Stump and Site Factor Analysis After Sanitary Logging of Bark Beetle-Infested Forests

South-East European Forestry
Coniferous forests cover 41% of Bosnia and Herzegovina, with Norway spruce (Picea abies) being an ecologically and economically important species. Bark beetles, especially the European spruce bark beetle (Ips typographus), pose a major threat, often ...

Evaluation of drone system for thinning operations–a case study in Sweden

International Transactions in Operational Research, EarlyView.
Abstract Thinning operations in forestry typically involve a two‐machine system (TMS) with a harvester and a forwarder. Its productivity in different forest conditions is well documented. To date, drones have been used for data collection and surveillance but not as an alternative to a TMS.

The Banded Elm Bark Beetle, Scolytus schevyrewi Semenov (Coleoptera, Curculionidae, Scolytinae) in North America: a taxonomic review and modifications to the Wood (1982) key to the species of Scolytus Geoffroy in North and Central America

ZooKeys, 2010
In 2003, an Asian bark beetle, Scolytus schevyrewi Semenov (Coleoptera: Curculionidae: Scolytinae), the banded elm bark beetle, was detected for the first time in North America.

Hydromulches in Organic Strawberry Production: Effects on Densities of Insect Pests and Natural Enemies

Journal of Applied Entomology, EarlyView.
ABSTRACT Liquid‐sprayable cellulose hydromulches (HM) are alternatives to plastic polyethylene (PE) mulches for weed suppression in organic agriculture. However, their impact on arthropod pests and natural enemies remains unexplored. Various HMs made of shredded newsprint, water and guar gum were compared against white‐on‐black PE mulch, paper sheet ...

Forecasting bark beetle early flight activity with plant phenology [PDF]

, 2016
Bark beetle outbreaks are a major threat to forest productivity, and a robust forecast of early flight activity is necessary for inhibition or mitigation of large-scale infestations.
