In the Aleppo pine forests at the Croatian Mediterranean in 2017, a Mediterranean bark beetle (Orthotomicus erosus) appeared in population densities that had not been recorded before and until then was not considered a significant pest in that area. Natural enemies are not able to follow a sudden increase of the bark beetle population, which results in rapid increase of drying trees. As a part of the suppression of the Mediterranean bark beetle in 2018, pheromone traps have been installed in Croatia for monitoring purposes. Although there are multiple options for applying different types of traps and pheromone preparations for the Mediterranean bark beetle, so far the differences in catches of different types of traps and their selectivity have not been investigated. In 2019, 40 pheromone traps were placed in the Forest Park ​​Marjan (Split) on 196 ha of forest area. A pairs of pheromone preparations Pheroprax and Erosowit were compared, a system of three traps (Triplet) with a single flight barrier trap as well as the modified wet flight barrier trap with a regular flight barrier trap. In addition to the average number of catches in pheromone traps, particular attention was given to selectivity. Two predator species Tanasimus formicarius and Temnochila caerulea were found in traps, with T. formicarius in insignificant quantities relative to T. caerulea. The results indicate that Erosowit exhibits significantly higher catches compared to Pheroprax and is significantly more selective. Pheroprax has a very high catches of T. caerulea predators and is not recommended for practical use. The Triplet had only slightly better catches compared to the single flight barrier trap, but also showed slightly better selectivity. The Triplet did not show the expected effect due to the amount of the catch, which was slightly higher than in the single trap, but not significantly in order to recommend their use.; U šumama alepskog bora na hrvatskom Mediteranu u 2017. godini pojavio se mediteranski potkornjak (Orthotomicus erosus) u gustoćama populacije koje do tada nisu zabilježene te se nikada prije nije smatrao značajnim štetnikom na tom području. Naglo povećanje populacije potkornjaka prirodni neprijatelji nisu u stanju pratiti, a ishod je naglo povećanje sušaca. U sklopu mjera zaštite za suzbijanje mediteranskog potkornjaka u 2018. godini u Hrvatskoj su postavljene feromonske klopke u svrhu monitoringa. Iako postoji više mogućnosti primjene različitih vrsta klopki i feromonskih pripravaka za mediteranski potkornjak, do sada nije istraženo koja je razlika u ulovima različitih vrsta klopki niti koliko su selektivne. U 2019. godini na području Park šume Marjan (Split) na 196 ha šumske površine postavljeno je 40 feromonskih klopki. Uspoređeni su parovi feromonskih pripravaka Pheroprax i Erosowit, sustav triju klopki Triplet sa običnom naletno barijernom klopkom te modificirana klopka sa mokrim ulovom i obična naletno barijerna klopka. Osim prosječnog broja ulova u feromonskim klopkama posebna pozornost dana je selektivnosti. Od predatora u klopama su značajnije su nađene dvije vrste, Tanasimus formicarius i Temnochila caerulea, s tim da je T. formicarius u odnosu na T. caerulea bio u zanemarivim količinama. Rezultati ukazuju kako pripravak Erosowit u odnosu na Pheroprax pokazuje značajno veće ulove, te je značajno selektivniji. Pheroprax ima vrlo visoke ulove predatora T. caerulea te se ne preporuča za praktičnu primjenu. Triplet je u odnosu na običnu naletno barijernu klopku pokazao tek neznatno bolje ulove, ali i nešto bolju selektivnost. Triplet nije pokazao očekivani učinak s obzirom na količinu ulova koja je bila nešto viša u odnosu na običnu klopku, ali ne značajnije kako bi se preporučila njihova primjena.
