Aphid parasitoids (Hymenoptera; Aphidiidae) were surveyed within grain production landscapes in Victoria, Australia between 2017 and 2018, as well as more sporadically nationwide between 2016 and 2019. In addition, aphidiine records were collated from insect depositories around Australia and online databases. The 5551 specimens recorded constituted a total of 23 species and seven genera. Diaeretiella rapae (MIntosh) was the most common species, representing more than 70% of all aphidiines recorded. This species also showed a greater northerly geographic range than other aphidiines. During sampling between 2017 and 2019, aphidiines were reared from mummies to ascertain host-parasitoid relationships. Diaeretiella rapae was again the most commonly reared parasitoid, although aphidiine preference varied with aphid host and between states and territories. An illustrated dichotomous key to Australian aphidiines in grain production landscapes is provided for the 11 species sampled in our field surveys. This is the first comprehensive review of aphidiines sampled within Australia in over two decades. Knowledge about the diversity and distribution of these parasitoids is important for understanding their impact on current and future invasions of aphid species. In addition, understanding the interactions between grain aphids and their associated parasitoids will further support the inclusion of parasitoid wasps into integrated pest management (IPM) strategies.

在澳大利亚谷物生产景观中，蚜虫黄蜂（膜翅目：Aphidiidae）寄生蚜虫（半翅目：Aphididae）的分类学，分布和寄主关系

在2017年至2018年之间，在澳大利亚维多利亚州的谷物生产景观中，以及在2016年至2019年间，在全国范围内对蚜虫类寄生虫（膜翅目；蚜虫科）进行了调查。此外，蚜虫碱记录来自澳大利亚各地的昆虫存放处和在线数据库。记录的5551个标本共构成23种7属。雷柏氏小肠藻（Mintosh）是最常见的物种，占记录到的所有蚜虫中的70％以上。与其他蚜虫相比，该物种的北区地理范围也更大。在2017年至2019年之间的采样中，从木乃伊中饲养了蚜虫碱，以确定宿主-寄生虫的关系。雷帕氏小肠藻再次是最常见的寄生蜂，尽管蚜虫的偏好随蚜虫寄主的不同以及州和领地之间的差异而变化。在我们的田间调查中，为11种物种提供了在谷物生产景观中澳大利亚蚜虫碱的图解说明的二分法关键。这是二十多年来澳大利亚境内首次对蚜虫碱进行的全面综述。了解这些寄生虫的多样性和分布对于了解它们对当前和未来蚜虫入侵的影响非常重要。此外，了解谷物蚜虫及其相关寄生虫之间的相互作用将进一步支持将寄生虫黄蜂纳入害虫综合治理（IPM）策略。这是二十多年来澳大利亚境内首次对蚜虫碱进行的全面综述。了解这些寄生虫的多样性和分布对于了解它们对当前和未来蚜虫入侵的影响非常重要。此外，了解谷物蚜虫及其相关寄生虫之间的相互作用将进一步支持将寄生虫黄蜂纳入病虫害综合治理（IPM）策略。这是二十多年来澳大利亚境内首次对蚜虫碱进行的全面综述。了解这些寄生虫的多样性和分布对于了解它们对当前和未来蚜虫入侵的影响非常重要。此外，了解谷物蚜虫及其相关寄生虫之间的相互作用将进一步支持将寄生虫黄蜂纳入害虫综合治理（IPM）策略。
