ABSTRACT

The present study on quantitative and qualitative losses in fruiting body of mushroom due to Tyrophagus putrescentiae Schrank (Acarina: Acaridae) infestation revealed significant effect of initial inoculums levels. The number of T. putrescentiae was statistically more (31.52 mites/ 10 g fruiting body) on highest initial inoculum (30 T. putrescentiae pairs) as compared to 20 mite pairs (18.52 mites/ 10 g fruiting body) and 10 mite pairs (5.90 mites/ 10 g fruiting body). The weight loss in fruiting body was 1.3, 4 and 4.5 percent at 10, 20 and 30 pairs of mites as initial inoculums. At the highest initial inoculation of 30 mite pairs, highest percent reduction in weight was recorded at all durations (0.47, 3.13, 5.13, 6.95, 7.70 and 8 % at 5, 10, 15, 20, 25 and 30 days, respectively). Significant reduction in total sugar, non reducing sugar, protein content of fruiting bodies was recorded during present study. It was 1.77, 1.73, 1.18 mg/10g fruiting body at 30 mite pairs as compared to 1.89, 1.80, 1.38 mg/10g fruiting body in control. Reducing sugar (0.04 mg/10g fruiting body) and starch content (0.02 mg/10g fruiting body) were statistically comparable with control (0.08, 0.03 mg/10g fruiting body, respectively).
