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. suzukiiis 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. suzukiiin 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 Leptopilinagenera, have been associated with D. suzukiiin 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. capitatahas 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 grenadensisAshmead and Leptopilina boulardi(Barbotin, Carton and Kelner-Pillault) and D. suzukii, and between the parasitoid Odontosema albinerveKieffer 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. |
