MARCUCCI, Bruno et al. Presencia de Goniozus legneri (Hymenoptera: Bethylidae) y su asociación con lepidópteros plagas en el oasis cultivado Norte de la provincia de Mendoza, Argentina. Rev. Soc. Entomol. Argent. [online]. 2023, vol.82, n.2, pp.5-5.  Epub 25-Jun-2023. ISSN 0373-5680.

Goniozus legneri Gordh (Hymenoptera: Bethylidae) is a larval ectoparasitoid of lepidopterans, with a worldwide history as a biocontrol agent of various agricultural pests. By means of extensive monitoring, this wasp was found in four distant districts of Mendoza province parasitizing three lepidopteran pests: Lobesia botrana (Den. et Shiff.) in grapevine, Ectomyelois ceratoniae (Zeller) in walnut and “espinillo” (Vachellia caven (Molina) Seigler et Ebinger) and Cydia pomonella (L.) in walnut. To corroborate the parasitoid species identification and to analyze its population viability in this region, studies of male genitalia and sexual crossings between wild and laboratory-reared wasps were conducted. Further, we report for the first time the natural host-parasitoid interaction of L. botrana with this parasitoid in vineyards from Argentina.
