Zoos and botanical gardens have a special role in the promotion, presentation and conservation of biodiversity in urbanised environments. Additionally, they provide special habitats for alien and invasive species. The formerly used methods of biodiversity assessments (e.g., light trapping, transect counts, etc.) are mostly labour-intensive and/or not efficient enough. In the Zoo of Debrecen, the efficacy and suitability of a synthetic (FLO) and a semisynthetic (SBL) lure for this purpose were proven. The qualitative and quantitative compositions of a moderately rich moth assemblage including 52 moth species were revealed, and the appearance and population dynamics of three invasive (<i>Helicoverpa armigera</i>, <i>Autographa gamma</i> and <i>Cydalima pespectalis</i>) and nine harmful pest species were also recorded. The results proved that the lures tested and traps used provide an easy-to-use, standardised and relatively cheap method for Zoos and botanical gardens to assess their biodiversity even in the case of limited resources.
