Background The introduction of species to new regions is occurring at an increasing rate. These introductions typically consist of species that are deliberately introduced for the purposes of biological control of pests or of species that are accidentally introduced through human-mediated transport networks. Understanding the potential and actual impacts of these introduced species requires comprehensive information on their geographic distributions and biological associations. However, apart from a few well-known case studies, such information is lacking for many introduced species which severely hinders further assessment of risks and impact. New information A dataset is provided on host associations, geographic distributions and dates of collection for both deliberately and accidentally-introduced parasitoid wasp species (Hymenoptera) in New Zealand. Information was obtained by digitising specimens from the New Zealand Arthropod Collection. Dates of records range from 1921 to 2017. The dataset includes 1265 specimen records, representing 127 parasitoid species from 12 families, with host records for 177 host species from 61 families and eight insect orders. These data provide baseline information to help evaluate the risk from introduced parasitoids to non-target and native species.

新西兰引进寄生蜂物种（膜翅目）的宿主记录数据集

背景 将物种引入新地区的速度越来越快。这些引入通常包括为生物防治害虫目的而故意引入的物种或通过人类介导的运输网络意外引入的物种。了解这些引进物种的潜在和实际影响需要有关其地理分布和生物关联的全面信息。然而，除了一些著名的案例研究外，许多引进物种缺乏此类信息，这严重阻碍了对风险和影响的进一步评估。新信息提供了有关主机关联的数据集，新西兰有意和意外引入的寄生蜂物种（膜翅目）的地理分布和收集日期。信息是通过对新西兰节肢动物收藏的标本进行数字化获得的。记录日期从 1921 年到 2017 年。该数据集包括 1265 个标本记录，代表 12 个科的 127 个寄生蜂物种，有来自 61 个科和 8 个昆虫目的 177 个寄主物种的宿主记录。这些数据提供了基线信息，以帮助评估引入的寄生蜂对非目标和本地物种的风险。有来自 61 个科和 8 个昆虫目的 177 个寄主物种的寄主记录。这些数据提供了基线信息，以帮助评估引入的寄生蜂对非目标和本地物种的风险。有来自 61 个科和 8 个昆虫目的 177 个寄主物种的寄主记录。这些数据提供了基线信息，以帮助评估引入的寄生蜂对非目标和本地物种的风险。
