Little has been published on scolytine beetles of the Moravian-Silesian Beskids, a mountain range at the border of Czechia and Slovakia. Available information was either very general or focused on bark beetles of spruce forests. Several beech-fir forests have been preserved in the area, the most valuable ones protected in nature reserves. Due to a general decline of the silver fir, monophagous species developing in this tree species should be considered threatened. In 2008, assemblages of bark and ambrosia beetles were studied in four montane old-growth beech-fir forests (situated in the reserves Mionší, Smrk, Salajka, and Razula) in the Beskydy (Beskids) Protected Landscape Area (north-eastern Czech Republic) using flight interception traps arranged into vertical transects (0.5 to 21 m above ground level). In total, 6,705 specimens of 27 species were collected. Three species were recorded for the first time from this area: Trypodendron laeve, Scolytus multistriatus and Xyleborinus attenuatus. S. multistriatus is given as vulnerable in the Red List for the Czech Republic and X. attenuatus is a non-indigenous species from eastern Asia. Also T. laeve was considered an introduced species from the Far East but currently it is assumed that its occurrence in Europe is autochthonous.
