We allocated some new types of bait traps using different volatile aromatic compounds in the Velyka Dobron’ Game Reserve (Ukraine, Transcarpathian region) where light trap surveys on Macroheterocera were already carried out since 2009. The phenylacetaldehyde-based traps were especially effective for the species of subfamilies Plusiinae and Helio-thinae, while the members of some other subfamilies (Hadeninae, Noctuinae) were more attracted by the isoamyl-alcohol-based traps. The highest attractivity was observed in case of the mixture containing isoamyl-alcohol, acetic acid and red wine. The highest num-ber of species was observed in mid-July, but the peak of individual numbers appeared in early August. Majority of species of this assemblage was formed by bivoltine species connected to herbaceous food plants. The dominant species of this late summer period was Trachea atriplicis (second brood). It was sharply replaced by the monovoltine Allophyes oxyacanthae in September. The bulk of species of this early autumnal period was formed by monovoltine species with woody-shrubby larval food plants. Biogeographical spectrum of the assemblage was dominated by widely distributed Euro-Siberian species combined with significant presence of Mediterranean and Boreo-continental faunal elements. In the ecological spectrum of the assemblage the species connected to forested habitats are well represented but together with the presence of numerous generalist species.
