Host tree preference and performance of the Eurasian spruce bark beetle (Ips typographus) on Scots pine

open access: yesPest Management Science, Volume 82, Issue 6, Page 5850-5860, June 2026.
Ips typographus showed lower reproductive output in an occasional host (Pinus sylvestris) under laboratory conditions, and did not prefer its main host (Picea abies) over P. sylvestris in two‐choice bioassays. Abstract BACKGROUND The Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with ...

Comparative study of volatile components from male and female flower buds of Populus × tomentosa by HS-SPME-GC-MS

open access: yes, 2018
The differences of volatile components in male (MFB) and female flower buds (FFB) of Populus × tomentosa were analysed and compared by HS-SPME with GC-MS for the first time. A total of 34 compounds were identified.

Comparison of Different Solid-Phase Microextraction Formats Dedicated to the Analysis of Volatile Compounds—A Comprehensive Study

open access: yesMolecules
The coupling of Solid-Phase Microextraction (SPME) technology with gas chromatography (GC) has a well-established and successful history. Traditionally, SPME fibers have been the most popular form thanks to their versatility and the ease with which they ...

SPME-multicapillary GC coupled to different detection systems applied to volatile organo-selenium speciation in yeast

open access: yes, 2004
In this work the versatility of solid phase microextraction (SPME) in combination with multicapillary gas chromatography (MC–GC) was evaluated using different common detectors for organo-selenium speciation.

Validation of an analytical method using HS-SPME-GC/MS-SIM to assess the exposure risk to carbonyl compounds and furan derivatives through beer consumption

open access: yes, 2019
Compounds with toxic potential may occur in beer, such as carbonyl compounds (acetaldehyde, acrolein, ethyl carbamate [EC] and formaldehyde) and furan derivatives [furfural and furfuryl alcohol (FA)].

Monitoring of Volatile Additives from Plant Protection Products in Tomatoes Using HS-SPME-GC-HRMS: Targeted and Suspect Approaches

open access: yes
Additives present in plant protection products (PPPs) are normally not monitored after sample treatments. In this study, the fate of additives detected by targeted and nontargeted analysis in tomato samples treated with two PPPs was carried out.

Green sampling of gas-phase volatile organic compounds using time-weighted average solid phase microextraction and gas chromatography - mass spectrometry: A critical review

open access: yesGreen Analytical Chemistry
Time-weighted average solid-phase microextraction (TWA-SPME) is a solvent-free passive sampling technique increasingly applied to volatile organic compounds (VOCs) monitoring in air. This review critically examines the theoretical foundations of TWA-SPME
