To develop biological programs for the spotted wing drosophila, Drosophila suzukii (Matsumura), the Mexican government placed sentinel traps with larvae and pupae of D. melanogaster Meigen from December 2017 to May 2018 in berry crops of Jalisco, Mexico. From those explorations, Ganaspis brasiliensis Ihering was identified as a first report in Mexico, although its presence in America has been noted in Brazil, Guadeloupe and Panama. This local parasitoid could contribute to the protection of the national berry industry by its field release or its hybridization with an exotic population highly specialized on D. suzukii.
