Global risks posed by hornets to the provision of crop pollination (UIB, IPE-CSIC)

Hornet (Vespa spp.) occurrences from the paper "Global risks posed by hornets to the provision of crop pollination". We carried out an extensive bibliographic review in search of occurrences present in papers published in English in Google Scholar and Web of Science. We employed keywords such as (?Vespidae? OR ?Vespa? OR ?hornet?) AND (?occurrence? OR ?distribution? OR ?native? OR ?invasive?) until November 2023 to identify relevant studies. Considering that many events are not published in scientific outlets because they are chance or isolated encounters, we also performed a Google search in English. Some of these occurrences only mentioned the location where individuals were found (village, city, or region), that were georeferenced through the Google Geocoding API, which returns central geo-coordinates. In total, we obtained 1210 from 49 research papers
