The Southeast Asian–native Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), also known as “spotted-wing Drosophila,” is one of the most globally invasive agricultural species. Although D. suzukii is a pest spread throughout all the Argentinian fruit-growing regions, few information has been published on its impact on local fruit production. Parasitoid species associated with D. suzukii in Argentina belong to Pteromalidae (Chalcidoidea), Diapriidae (Diaprioidea), both attacking host pupae, and Figitidae (Cynipoidea), which attack host larvae. Nine Eucoilinae (Figitidae) species, belonging to Dicerataspis, Dieucoila, Euxestophaga, Ganaspis, Hexacola, and Leptopilina genera, have been associated with D. suzukii in Argentina. Ceratitis capitata (Wiedemann), commonly known as “medfly,” is native to Africa and has a worldwide distribution, covering many tropical, subtropical, and temperate regions. In Argentina, C. capitata has been associated with several native hymenopterous parasitoids belonging to Braconidae (Ichneumonioidea), Eulophidae (Chalcidoidea), Pteromalidae, Diapriidae, and Figitidae families. Only two eucoline species, Ganaspis pelleranoi (Brèthes) and Leptopilina haywardi (Blanchard) have been related to medfly in Argentina. We report new trophic associations between the parasitoids Dicerataspis grenadensis Ashmead and Leptopilina boulardi (Barbotin, Carton and Kelner-Pillault) and D. suzukii, and between the parasitoid Odontosema albinerve Kieffer and C. capitata, after surveys conducted in Tucumán, northwestern Argentina. An annotated checklist and a taxonomic key of Eucoilinae associated with both invasive pests, in Argentina, are also provided.

东南亚本土果蝇 suzukii（松村）（双翅目：果蝇科），也称为“斑翅果蝇”，是全球最具入侵性的农业物种之一。尽管铃木果蝇是一种遍布阿根廷所有水果种植区的害虫，但关于其对当地水果生产影响的信息却很少。阿根廷与D. suzukii相关的拟寄生物种类属于 Pteromalidae (Chalcidoidea)、Diapriidae (Diaprioidea)（均攻击寄主蛹）和 Figitidae (Cynipoidea)（攻击寄主幼虫）。九种真蠹亚科 (Figitidae) 物种，分别属于Dicerataspis、Dieucoila、Euxestophaga、Ganaspis、Hexacola和Leptopilina属，与阿根廷铃木蠹虫有关。头状实蝇（Wiedemann）俗称“地中海蝇”，原产于非洲，分布于世界各地，覆盖许多热带、亚热带和温带地区。在阿根廷，C. capatata与属于茧蜂科 (Ichneumonioidea)、Eulophidae (Chalcidoidea)、翼龙科 (Pteromalidae)、Diapriidae 和 Figitidae 科的几种本地膜翅目寄生蜂有关。在阿根廷，只有两种真绿物种与地中海果蝇有亲缘关系：Ganaspis pelleranoi (Brèthes) 和Leptopilina haywardi (Blanchard)。在阿根廷西北部图库曼进行调查后，我们报告了寄生蜂Dicerataspis grenadensis Ashmead 和Leptopilina boulardi (Barbotin、Carton 和 Kelner-Pillault) 与D. suzukii之间，以及寄生蜂Odontosema albinerve Kieffer 和C. capitata之间的新营养关系。还提供了阿根廷与这两种入侵害虫相关的带注释的清单和分类索引。
