title: Data for: International non-native Hemiptera invasion database

description: Aim The Hemiptera is the fifth-largest insect order but comprises more
 established non-native insect species than any other insect order. This
 over-representation may result from high propagule pressure or from high
 species invasiveness. Here, we assess the reasons for over-representation
 in this group by analyzing geographical, temporal and taxonomic variation
 in numbers of historical invasions. Location Global Method We assembled
 lists of historical Hemiptera invasions in 12 world regions, countries or
 islands (Australia, Chile, Europe, New Zealand, North America, South
 Africa, South Korea, Japan, and the Galapagos, Hawaiian, Okinawa, and
 Ogasawara Islands) and border interception data from 9 countries
 (Australia, Canada, European Union, United Kingdom, Hawaii, Japan, New
 Zealand, South Korea, USA mainland, South Africa). Using these data, we
 identified hemipteran superfamilies that are historically over-represented
 among established non-native species, and superfamilies that are
 over-represented among arrivals (proxied by interceptions). We also
 compared temporal patterns of establishments among hemipteran suborders
 and among regions. Results Across all regions, patterns of over- and
 under-representation were similar. The Aphidoidea, Coccoidea,
 Aleyrodoidea, Cimicoidea and Phylloxeroida were over-represented among
 non-native species. These same superfamilies were not consistently
 over-represented among intercepted species indicating that propagule
 pressure does not completely explain the tendency of some Hemiptera to be
 over-represented among invasions. Asexual reproduction is common in nearly
 all over-represented superfamilies and this trait may be key to explaining
 the exceptional invasion success of these superfamilies. Geographical and
 temporal patterns of historical numbers of species established per decade
 mirror trends of naturalization of non-native plants. Conclusions We
 conclude that both propagule pressure and species invasiveness traits are
 drivers of the exceptional invasion success of the Sternorrhyncha suborder
 and Hemiptera in general. Most Hemiptera are plant-feeding; we conclude
 that non-native plant invasions provide ecological niches for non-native
 Hemiptera and play a role in driving their invasions worldwide.
description: These data list individual non-native Hemiptera species
 established in 12 regions around the globe: Australia, Chile, Europe
 (including its major islands and the European part of Russia), the
 Galapagos Archipelago, the Hawaiian Archipelago,  Japan (excluding
 outlying islands), New Zealand, Okinawa (Nansei Islands), North America
 (Canada, continental USA), the Ogasawara Islands (also known as Bonin
 Islands, Japan), South Africa, and South Korea. Family, superfamily and
 the year of initial discovery in each region where it is present are
 included for records when these data are available.
 This dataset was assembled from various sources by an
 interdisciplinary scientific working group. Most of the records here are
 also included in Turner, R., Blake, R., & Liebhold, A. M. (2021).

 [https://doi.org/10.5061/dryad.7m0cfxq2v](https://doi.org/10.5061/dryad.7m0cfxq2v) These data list individual non-native Hemiptera species established in 12 world regions, Australia, Chile, Europe (including its major islands and the European part of Russia), the Galapagos Archipelago, the Hawaiian Archipelago, Japan (excluding outlying islands), New Zealand, North America (Canada, continental USA), the Ogasawara Islands (also known as Bonin Islands, Japan), Okinawa (Nansei Islands), South Africa, and South Korea. Taxonomy, attributes and occurrences for each taxa are included.  Occurence records for species that were intentionally introduced, were successfully eradicated or are only established indoors (e.g., in greenhouses) were excluded from this database. Data have been cleaned of most typographic and taxonomic errors using the code in the R package insectcleanr: Initial release (DOI: 10.5281/zenodo.4555787), which is based on the Global Biodiversity Information Facility (GBIF) taxonomic backbone (GBIF Secretariat (2021).

Data cells containing "NA" correspond to missing data. One record corresponds to the first record of an established species in one of the 12 regions. Species that are established in multiple regions therefore will have multiple entries.  ## Sharing/Access information This database is mostly (but not entirelly) a subset of Turner, R., Blake, R., Mally, R., & Liebhold, A.
