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.

本研究记录了自然条件下，数种新热带区原生的Zygothrica属（Zygothrica，隶属于双翅目（Diptera）果蝇科（Drosophilidae））严重侵染香菇（shiitake）的首例观测结果。此次侵染发生于农林复合模式下的中型段木香菇栽培体系中。该香菇栽培场位于巴西巴拉那州（Paraná）坎普拉戈市（Campo Largo），地处大西洋森林生物群区（Atlantic Forest Biome）内。研究团队于2023年12月采集了该类成虫的雌雄个体。本研究首次从段木香菇栽培体系中采集到Zygothrica parapoeyi Burla, 1956、Z. hypandriata Burla, 1956、Z. ptilialis Burla, 1956及Z. paraptilialis Burla, 1956这四个物种。此次记录凸显了针对巴西森林（尤其是农林复合系统内）的大型真菌侵染开展野外研究的重要性，以及这类侵染潜在的经济影响。基于此研究背景，本团队同时提出了若干初步的预防性防控措施。
