Types of insects attacking white button mushrooms and their population fluctuation were studied during the cropping season of 1990-1991. Mean total population revealed a relationship with temperature fluctuation during the period. Insects belonging to five orders viz., Diptera, Hymenoptera, Coleoptera, Collembola and Homoptera were recorded, among which Diptera accounted for the highest population (18.5 +- 0.53/trap/day, 94.9% of the total population). Highest overall population among the Dipterans was attributed to Phoridae (8.58 +- 0.31), followed by Sciaridae (5.58 +- 0.26) and Cecidomydae (4.56 +- 0.23). In respect of the families, population fluctuation revealed a varying trend in the different months. Crop yield was considerably affected by insect pest damage (49% reduction in comparison to control).
