The results of a pilot study of xylophagous insects in a ribbon pine forest, weakened by pine tree lappet moth Dendrolimus pini and ground fire, in the southern Altai Area are presented here. In June–July 2025, overall, 447 specimens from 17 species and three families (Cerambycidae, Curculionidae, and Buprestidae) were captured in two pheromone traps. The pine sawyer beetle Monochamus galloprovincialis and the six-toothed bark beetle Ips sexdentatus were dominant (in total up to 68 % of catches). These insects, along with the bark beetle Ips acuminatus, the weevils Pissodes piniphilus and Hylobius abietis, and the jewel beetles Phaenops cyanea and Buprestis haemorrhoidalis, are economically significant species. The assessment of the composition and abundance of xylophages in the catches is provided, which can serve as a basis for further monitoring and optimization of forest protection measures in the region.
