We found that the cultivated oyster mushroom, Pleurotus ostreatus, was damaged by the phorid fly, Megaselia tamiladuensis Disney (Diptera: Phoridae). This fly is newly recorded as a pest in Korea. Brief morphological characteristics are described.

Among flies inside mushroom growing rooms in three farms, Lycoriella ingenua and Megaselia tamilnaduensis were the most common and dominant species during Pleurotus ostreatus cultivation in Korea. In the past, generally, during the incubation period, a low density of mushroom flies was observed in all farms. After the first harvest, mushroom flies density tended to increase sharply. However, many mushroom flies were observed in the summer, despite that season corresponds to the incubation period. This is because annual cultivation systems provide a safe overwintering place compared to seasonal selective ones. The ecology of mushroom flies varies greatly according to the cultivation system. We confirmed that a fallow period reduced the density of mushroom flies. From a survey of the three dimensional distribution of mushroom flies in a growing room, we observed that M. tamilnaduensis showed more positive phototaxis and a higher variation per point of capture than that by L. ingenua. Through this study, two mushroom fly species were identified in the survey farms, with markedly different three dimensional distribution patterns.
