Interpretive Summary: A new fungal disease of Spotted Wing Drosophila Flies is described with notes on its potential for biological control.

Technical Abstract: We report on the first confirmed case of a fungal (Entomophthora spp.) epizootic on wild spotted wing Drosophila (SWD) populations visiting fig trees in Central Mississippi. Host behavior is typical of other fly hosts infected with Entomophthora; flies seek high spots in moist and dark microhabitats. Infection may be further enhanced when males copulate with diseases female SWD. The unusually cool and rainy June in Mississippi may have spurred this epizootic, providing some hope that this disease could be exploited to control SWD during the summer months.
