Zygothrica species_Data.xlsx

We document the first observation of a severe shiitake mushroom infestation by several native Neotropical <i>Zygothrica</i> species (Drosophilidae, Diptera) under natural conditions. This infestation occurred in an agroforestry model, a medium-scale, log-based shiitake mushroom production culture. The mushroom farm is located in the Campo Largo municipality in the state of Paraná, Brazil, within the Atlantic Forest Biome. Adult flies, both males and females, were collected in December 2023. This study represents the first collection of <i>Zygothrica parapoeyi</i> Burla, 1956, <i>Z. hypandriata</i> Burla, 1956, <i>Z. ptilialis </i>Burla, 1956<i> </i>and <i>Z. paraptilialis</i> Burla, 1956 from shiitake log culture. This record underscores the importance of field studies on macroscopic fungal infestations in Brazilian forests, particularly those within agroforestry systems, and their potential economic impacts. In this context, we also propose some preliminary preventive management actions.
