Species distribution models of the Spotted Wing Drosophila (Drosophila suzukii, Diptera: Drosophilidae) in its native and invasive range reveal an ecological niche shift

The Spotted Wing Drosophila (Drosophila suzukii) is native to Southeast Asia. Since its first detection in 2008 in Europe and North America, it has been a pest to the fruit production industry as it feeds and oviposits on ripening fruit. Here we aim to model the potential geographical distribution of D. suzukii. We performed an extensive literature review to map the current records. In total, 517 documented occurrences (96 native and 421 invasive) were identified spanning 52 countries. Next, we constructed three species distribution models (SDMs) based on occurrence records in: 1) the native range (SDMnative), 2) the invasive range in Europe (SDMEurope) and 3) a global model of all records (SDMglobal). The models aimed to investigate, whether this species will be able to occupy additional ecological niches beyond its native range and expand its current geographic distribution both globally and in Europe. The SDMs were generated using Maximum Entropy algorithms (Maxent) based on present ...,
Occurrence records of Drosophila suzukii

Microsoft Excel spreadsheet with two worksheets (tabs).
 
First sheet: Information about all 517 occurrence records used in the study, as obtained through extensive literature review and through mining online databases, e.g. Taxodros (http://www.taxodros.uzh.ch) and European and Mediterranean Plant Protection Organization (EPPO - https://www.eppo.int). Columns describe: country, state or region (if applicable), latitude, longitude, the year of the first observation at the specific site (if available), status, and references. Regarding the status we distinguish between: widespread, present, restricted distribution, and few occurrences similar to the EPPO and the National Plant Protection Organizations (NPPOs) of the International Plant Protection Convention (IPPC: https://www.ippc.int/en/news/tag/nppo/). In most information sources, GPS coordinates of occurrences were given, but in the cases where direct coordinates could not be obtained, the GP...,
