Abstract

We report the first detection of the plant pathogenic yeast Eremothecium coryli in the Czech Republic and identify the invasive brown marmorated stink bug, Halyomorpha halys, as a vector. E. coryli causes yeast spot diseases in crops such as soybeans, hazelnuts, and tomatoes, primarily in tropical and subtropical regions. The yeast was identified in the foregut of H. halys specimens collected in a cherry orchard near the hazelnut shrubs using PCR amplification and sequencing of the ITS and LSU gene regions. Phylogenetic analysis confirmed the identity of E. coryli and its association with H. halys, as discussed.
