Abstract
Â
 The predominant dipteran insects collected from mushroom farms located in various districts of H.P. were identified as Sciara sp with the help of available literature and taxonomic keys. Identification was got confirmed from the taxonomist Dr. V V Rama Murthy, division of Entomology at IARI. Sciara eggs collected from Agaricus bisporus mycelium were microscopic, smooth and oval in shape averagely measuring 0.21 mm in length and 0.15 mm in breadth. The newly hatched maggots were cylindrical with a shining black head and body tapering towards the posterior end. The maggots matured through four larval instars within 13-14 days to reach the average length of 5.58 mm and breadth of 0.50 mm. The matured maggots turned into non-feeding pre-pupae. Pre-pupal phase lasted for 1-3 days. Pupal period varied from 2 to 3 days with an average of 2.27±0.44. Average duration of female and male fly was 5 to 7 days and 4 to 6 days, respectively. The development period from egg to adult emergence varied from 11 to 19 days and averaged 13.67±2.44 days.
