“…There were two consecutive D. suzukii invasion events in Argentina from previously invaded areas such as North America and Brazil (de la Vega et al., 2020). Since its first detection in the country in 2014 (Funes et al., 2023), a broad range of resident figitid larval‐pupal parasitoid species have been identified in the last few years attacking D. suzukii , such as L. clavipes, Ganaspis hookeri Crawford (Lue et al., 2017) , G. pelleranoi (Brèthes) (Gallardo et al., 2022a), G. brasiliensis (Gallardo et al., 2022b), L. boulardi (Garrido et al., 2018), Euxestophaga argentinensis Gallardo, Hexacola bonaerensis Reche, and Dieucoila octofagella Reche (Reche et al., 2021). Despite this diversity, none of these parasitoid species were abundant, nor did they provide reliable control of the invasive pest, which is expected due to the short interaction time.…”

The Asian Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a harmful invasive pest widespread throughout Argentinian fruit‐producing regions. It coexists with both pests, the sub‐Saharan African Ceratitis capitata (Wiedemann) and the Neotropical‐native Anastrepha fraterculus (Wiedemann) (both Diptera: Tephritidae), in northwestern Argentina. The Neotropical‐native parasitoid Ganaspis pelleranoi (Brèthes) (Hymenoptera: Figitidae) is frequently found in non‐crop fruit infested by those frugivorous dipterans. The northwestern Argentinian region is known for producing and exporting berries and citrus, which are affected by those pests. Thus, eco‐friendly control strategies are under assessment. This study mainly assessed the potential of the G. pelleranoi population lineage from Tucumán (GpTuc) as a D. suzukii biocontrol agent. First, both the host‐killing effectiveness and the reproductive success of GpTuc on larvae of D. suzukii, C. capitata, A. fraterculus, and Drosophila melanogaster Meigen were compared in no‐choice tests under laboratory conditions. Then, the GpTuc host preference was evaluated in dual‐choice tests (D. suzukii vs. C. capitata or A. fraterculus) under laboratory and field conditions. Naive parasitoid females were allowed to forage for 8 h on screen‐covered Petri dishes filled with host larvae under laboratory conditions and for 48 h on peaches inoculated with host larvae under field conditions. Host puparia dissections were performed to determine the number and condition of parasitoid eggs, first and second instars, such as alive/dead, without/with melanization process, and proportions of parasitized, superparasitized, and dead puparia. Drosophila suzukii was not a suitable host for the successful development of GpTuc immature stages as they did not overcome the host's immune system. However, GpTuc performed efficiently regarding D. suzukii mortality, but parasitoid specificity was restricted to both tephritid species as only thriving offspring were achieved from them. Interestingly, the effectiveness of GpTuc on D. suzukii increased when it co‐occurred with C. capitata instead of A. fraterculus, the preferred host.

“…They have since established adventive populations (Beers et al, 2022). G. brasiliensis is also found in several Central and Southern American countries (Buffington & Forshage, 2016; Gallardo et al, 2022; Gonzalez‐Cabrera et al, 2020) and has been released since 2021 as part of a classical biological control programme in Italy (Fellin et al, 2023). L. japonica is less widely distributed and the only report outside of its area of origin in Southeast Asia (Novković et al, 2011) or North America (Abram et al, 2020) is from Italy in 2019 (Puppato et al, 2020).…”

First record of Leptopilina japonica Novković & Kimura, 2011 (Hymenoptera: Figitidae) in Germany, a parasitoid of the Spotted Wing Drosophila Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae)

Two years after the first European record in Italy, we report the first occurrence of the parasitoid wasp Leptopilina japonica Novković & Kimura, 2011 (Hymenoptera: Figitidae) in Germany. The species is a larval‐pupal parasitoid of Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), which is a widespread invasive and economically important pest of soft‐skinned fruit. In total, we found 29 specimens of L. japonica in five different locations in southern and western Germany in the years 2021, 2022 and 2023. We examined the specimens morphologically and generated their DNA barcodes for identification. In three of the locations, L. japonica was sampled from raspberries. In two locations, L. japonica was caught in two and three consecutive years, respectively, which indicates adventive establishment. As D. suzukii and L. japonica originate from the same region in Asia, the possible establishment of L. japonica could be a case of unintentional biological control in Germany. In addition to this first record in Germany, we present a diagnosis of L. japonica to distinguish the species from the rest of the European Leptopilina fauna.
