The aim of this study was to assess its occurrence in Slovakia based on multi-year surveys conducted in the Z\u00e1horie region and to document its first national record. Monitoring was carried out in 2021 and 2025 in pine-dominated stands using traps baited with pheromone and kairomone attractants. No individuals were detected in 2021. In 2025, two adults of G. materiarius were captured at a single site during the first inspection of traps baited with a (+)-\u03b1-pinene and ethanol blend. A large volume of stored pine timber was present in close proximity to the capture site, providing suitable breeding material. The findings suggest a recent introduction or early stage of establishment in Slovakia. Although the species is regarded as a technical pest of coniferous wood, it does not colonize healthy trees and currently poses a limited risk to vital forest stands. Continued targeted monitoring is important to assess its further spread.<\/jats:p>","DOI":"10.3390\/insects17050532","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T15:02:27Z","timestamp":1779375747000},"page":"532","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["First Confirmed Detection of Gnathotrichus materiarius (Fitch, 1858) (Coleoptera: Curculionidae: Scolytinae) in Slovakia"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1794-5222","authenticated-orcid":false,"given":"Michal","family":"Lal\u00edk","sequence":"first","affiliation":[{"name":"National Forest Centre, Science and Research Section, T.
