First record of Stigmatomyces (Ascomycota: Laboulbeniales) on Drosophilidae from Japan

Abstract

Three Stigmatomyces species were detected on five drosophilid species from Japan. We report Stigmatomyces majewskii on Drosophila rufa and Drosophila suzukii, Stigmatomyces scaptodrosophilae on Scaptodrosophila coracina and Scaptodrosophila subtilis, and Stigmatomyces sacaptomyzae on Scaptomyza graminum. Except for Scaptomyza graminum, each of these species is a newly identified Stigmatomyces host. Our discovery that D. suzukii is a host of S. majewskii may provide new pest management approaches for this global agricultural pest insect.
