Description
South Tyrol, Northern Italy, faces a significant data gap regarding wild bee diversity. In this study, we present findings from 3,313 wild bee specimens collected over two consecutive years in two different studies in agricultural and mountainous environments. Using colored pan traps, we identified 150 species and documented their occurrence data. Our species list enhances regional and national wild bee databases by providing new distribution records for EU extinction-threatened species, including Dufourea dentiventris, Dufourea inermis, Lasioglossum brevicorne, Lasioglossum laevigatum, Lasioglossum monstrificum, Nomada mutica, and Nomada villosa. Additionally, we report recent records of species that help document range expansions, update historical data, and highlight previously unrecorded species in South Tyrol.

Méthodes d'échantillonnage
In the first study (2021) we positioned nine white pan traps at each site to attract wild bees visiting apple flowers. Pan traps were plastic plant saucers (Geli GmbH; 500 mL, internal diameter of 14.5 cm), which were coated with white UV-reflecting colour (Spray-ColorGmbH, Sparvar Leuchtfarbe). Pan traps were arranged along three adjacent rows of trees at the centre of each orchard. Each trap was placed at 1.10 m height at the branch level and spaced 10 m apart along the row (3 m between rows and 10 m from the field margins). Pan traps were filled with water and detergent (one tablespoon of uncoloured, unscented liquid soap per 5 L of water) to reduce surface tension and were deployed for 48 hours in the field. The biological content of each trap was preserved in 70% ethanol. Similarly, also in the second study (2022) pan traps were filled with water and detergent. However, in this case, pan traps were left in the field for 24 hours. Together with white pan traps, we also used blue and yellow ones to attract a broader range of wild bee species. In every site, two sets of three UV-reflecting pan traps (same product specifics as in 2021) were placed at vegetation height. Each set consisted of a blue, a white, and a yellow pan trap placed 5 m apart. The sets were placed 10 m apart and at least 10 m from field margins.
| Etendue de l'étude | The sampling are is South Tyrol, in Northern Italy. In the first study, we visited 14 apple orchards distributed along a gradient from apple-dominated surroundings to a more heterogeneous landscape matrix. Data collection occurred during the apple tree blossoming season (14th April – 3rd June 2021). Sampling comprised three rounds: early, peak, and late mass flowering, with an average interval of 8 ± 3 days between rounds. The second study investigated how wild bee diversity and pollination services were influenced by elevation (coincident with a climatic gradient) and a bioindicator reflecting the local biodiversity used as a proxy for land-use intensity. In this study, we visited a total of twenty-four sites: five apple orchards (visited previously during the first survey), five vineyards, four pastures, six meadows, two orchard meadows, and two annual crops (potato fields). Three rounds of sampling were conducted between 10th May and 18th July 2022, with an average interval of 29 ± 5 days between repetitions. |

Description des étapes de la méthode:
- For the bees collected during the first year, a specimen (of both sexes, if present) per species per site was prepared to be stored in an insect box. In the second year, we prepared one specimen (of both sexes if present) per species. All the other bees are labelled, temporarily stored in 70% ethanol, and checked regularly in case ethanol refilling is necessary. The specimens will be temporarily kept by the Institute for Alpine Environment at Eurac Research for further research and then gifted to the “Naturmuseum Südtirol”, the South Tyrol Museum of Nature in Bolzano/Bozen.
