Abstract
This dataset provides ecological, climatic, and entomological field data related to the monitoring of ambrosia beetle populations in the Pesio and Susa valleys, NW Italy, across two years (2024 and 2025). The dataset comprises 1,680 observations and 36 variables, structured to facilitate the analysis of beetle trapping data in relation to environmental and habitat parameters. The data are provided in a tabular format where key variables include temporal and spatial identifiers (year, date, area, city, trap ID, and trapping replicate) alongside localised climatic averages (temperature and precipitation). The habitat context is deeply characterised by the type of environment (chestnut orchard vs. mixed environment), the specific trap placement relative to the forest edge (interior vs. exterior), and the surrounding tree community composition (quantified for multiple tree species such as Castanea sativa, Prunus avium, Betula pendula, among others). The biological response variables consist of individual count values for specific beetles, recorded under the columns: Ad (Anisandrus dispar), Xc (Xylosandrus crassiusculus), Xg (Xylosandrus germanus), Xs (Xyleborinus saxesenii), Xm (Xyleborus monographus), Am (Anisandrus maiche), collected from the traps. This dataset holds high reuse potential for researchers in entomology, forest ecology, and climate impact studies. The data can be integrated into broader meta-analyses, used to model the population dynamics and phenology of ambrosia beetles, or employed to investigate how forest edges, local tree biodiversity, and climatic factors influence beetle distribution. It provides a robust baseline for monitoring potential invasive pests or studying forest health management strategies.
Dataset Information
This dataset contains ecological, climatic, and entomological field data related to the monitoring of ambrosia beetles community in the Pesio and Susa valleys, NW Italy, across two years (2024 and 2025).

Data was derived from field trapped ambrosia beetles.
Data & File Overview
File List:
'DB_scolytidae.csv': dataset containing all environmental, climatic, and beetle trapping data.
File format:
'DB_scolytidae.csv': semicolon-delimited with commas for decimal separators.
Methodological Information
Data were collected in the field using traps placed in chestnut orchards and mixed environments, both at the interior and exterior of the site. Localised environmental parameters (temperature and precipitation) were recorded, and the surrounding tree community composition was evaluated for multiple species. Traps were checked every ten days from March to October.

Missing data codes:
'NULL' cells: In the columns relating to beetle counts (Ad, Xc, Xg, Xs, Xm, Am), NULL values indicate that during that specific replicate, the traps were found on the ground due to adverse weather conditions, making it impossible to collect the samples and count the individuals.
