Hymenoptera Catches of Traps with Synthetic Generic Lures from Transcarpathia (West Ukraine)

Between 2014 and 2016, traps baited with synthetic generic lures were used to collect data on insect diversity, with a focus on Lepidoptera pest assemblages in the surroundings of Velyka Dobron' in Transcarpathia, West Ukraine. Traps captured a large number of insects from various taxa, including Hymenoptera, providing valuable data on both the poorly known regional fauna and the attractiveness of the lures to different Hymenoptera groups. In total, 1214 individuals were recorded, representing 11 families and 39 species, of which 17 species are reported from Transcarpathia for the first time. The majority of the sample (97%) belonged to the families Apidae and Vespidae. The Apidae and Halictidae species were predominantly attracted to phenylacetaldehyde-based lures, while Vespidae species responded more to semisynthetic lures containing isoamyl alcohol. The parallel use of the tested lures with different selectivity appears to be an effective, user-friendly, standardized method for studying Hymenoptera assemblages. Furthermore, knowledge of lure selectivity allows for the target collection of species belonging to different ecotypes.
