The purpose of the diploma thesis was to conduct monitoring of the autochthonous and non-native species of the genus Monochamus in the vicinity of two warehouses with wooden packaging material imported from Asia and to determine the caught beetles (Coleoptera). Monitoring took place from 11 May 2018 to 26 October 2018 at the Teharje and Breg locations. WitaPrall IntPt cross-vane panel traps with Galloprotect Pack lure were used, and ethylene glycol was poured into the capture container to collect and preserve the captured specimens. The catch from the traps was generally collected every 14 days, and the lures were changed on every other such occasion. A total of 547 beetles (Coleoptera) were caught at both locations. Overall, 28 different families were represented in the catch, the most numerous of which were the longhorn beetles (Cerambycidae), the true weevils (Curculionidae) and the checkered beetles (Cleridae). Five different species of longhorn beetles were caught, namely Spondylis buprestoides, Monochamus galloprovincialis, Acanthocinus griseus, Arhopalus rusticus and Strangalia attenuata. No alien pine sawyer species (Monochamus spp.) were detected in the catch. Among the bark beetles (Curculionidae: Scolytinae), the most numerous species was Xyleborinus saxesenii, and the checkered beetles were almost entirely represented by Thanasimus formicarius, which is considered to be the most important predator of bark beetles.
