Here, we provide abundance data, the respective R-script and R-readable data files from a small-scale study on hymenopteran parasitoid communities and their hosts, with special focus on pentatomoid bugs and their egg parasitoids. This comparative study was conducted in farmland and semi-natural ecotones from June to September 2020 in South Tyrol, Italy. The fauna was sampled during four sampling events with sweep netting, beat netting, yellow pan traps, Malaise traps and visual inspections. Arthropods were identified to order level, hymenopteran parasitoids to family level, pentatomoid bugs to species level and egg parasitoids of pentatomoids as far as possible to species level. If identification was not possible, pentatomoid parasitoids were left at genus level. The abundance data collected with each survey method were pooled per survey events and survey site.
