A study was conducted to assess the role of Tyrophagus putrescentiae in dispersal of Mycogone perniciosa, a causative agent of wet bubble disease in Agaricus bisporus. T. putrescentiae started feeding as soon as they were released in M. perniciosa culture plates. A continuous significant increase in mite number was recorded at each observation period with peak (150.50 mites) after 20 days which was statistically comparable with 145.50 mites at 18 days. After 15 days, 10 T. putrescentiae pairs were released from M. perniciosa infected plates to A. bisporus culture plates under aseptic conditions. After 6 days, whitish mouldy growth was started appearing on A. bisporus culture which soon spread to whole culture plate within 18 days. Mites were feeding and multiplying at this stage. The mite number significantly increased with increase in observation period on A. bisporus culture plates till 22nd day. At this stage peak in the population was recorded (177.25 mites).
