First Record and Distribution of Ganaspis brasiliensis(Hymenoptera: Figitidae: Eucoilinae), a Parasitoid of Drosophila suzukii(Diptera: Drosophilidae) in Argentina

Abstract

The eucoiline species Ganaspis brasiliensis(von Ihering) (Hymenoptera: Figitidae) is recorded for the first time in Argentina, with confirmation of parasitism of Drosophila suzukii (Matsumura) infesting healthy raspberry fruit (Rubus idaeus L. cv. Heritage) still on the plant. Drosophila suzukiipuparia were recovered from fruit collected in an organic farm in Tafí del Valle, Tucumán, Argentina. One G. brasiliensisspecimen was obtained from an isolated D. suzukiipuparium. An additional 83 specimens, deposited in the entomological collection of the Museo de la Plata, Argentina, were also identified as G. brasiliensis. This parasitoid species is distributed in four biogeographical provinces of Argentina. The specimens of G. brasiliensiscollected in Argentina are assumed to belong to a worldwide distributed and generalist lineage, parasitizing several Drosophilaspecies. A taxonomic key of known Ganaspisspecies from Argentina is provided.
