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.

本研究首次记录了自然条件下，数种新热带界原生的赞果蝇属（<italic>Zygothrica</italic>）物种（双翅目Diptera：果蝇科Drosophilidae）对香菇造成严重侵染的现象。此次侵染发生于一种农林复合模式下的中型段木栽培香菇生产体系中。该香菇种植场位于巴西巴拉那州坎波拉戈市，地处大西洋森林生物群落范围内。研究人员于2023年12月采集了该果蝇的雌雄成虫。本研究首次从段木栽培香菇基质中采集到<italic>Zygothrica parapoeyi</italic> Burla, 1956、<italic>Z. hypandriata</italic> Burla, 1956、<italic>Z. ptilialis</italic> Burla, 1956以及<italic>Z. paraptilialis</italic> Burla, 1956这四个物种。此次记录凸显了对巴西森林（尤其是农林复合系统内）中的大型真菌侵染现象开展野外研究的重要性，以及这类侵染潜在的经济影响。基于此背景，本研究同时提出了若干初步的预防性防控措施。
