Mushroom sciarid fly Lycoriella ingenua (Dufour), syn. L. mali (Fitch) is one of the most common fly pests affecting the mushroom cultivation in Korea. This study was carried out to investigate the development at different temperatures and damages of L. ingenua in A. bisporus mushroom cultivation. Rearing of mushroom flies were carried out on mycelial culture in Petri dishes. The development of L. ingenua from egg to adult at the temperature of 16, 20, 24, 28oC were 35.2, 25.8, 23.5, and 22.2 days, respectively. Adult flies invade mushroom farms and oviposit in freshly spawned compost. Damages are mainly caused by the larvae of 1-7 mm, which feed on growing mycelium and also developing stipes and caps of mushrooms. Adult flies spoil the appearance of the fruiting bodies, spread various fungal and bacterial disease, and transmit mites. The damages by mushroom flies increased without pest control causing yield loss of up to 27%.
