Abstract
A novel trap designed for monitoring parasitoids of spotted-wing Drosophila (SWD) is described. This new trap utilizes host fruits that are known host substrates for SWD and chocolate or vanilla baits, yielding a more accurate measure of SWD-parasitoids populations than banana traps. Fieldwork was carried out in Michoacan, Mexico, and the dominant parasitoids captured were all Figitidae: Leptopilina boulardi Barbotin, Carton and Kelner-Pillault and Ganaspis brasiliensis Ihering. The capture of Ganaspis brasiliensis is the first record of this species in Michoacan, and using DNA ‘COI barcode’ data, this Mexican population is consistent with the G5 population. We conclude that it is possible to promote this species as a biological control agent through inoculation and conservation in organic production of blackberry against D. suzukii, through an “Augmentoria” strategy using our sentinel trap with chocolate baits and preferred host of SWD to attract more SWD-parasitoids.
