Effect of six insecticides has been studied on seven edible fungi under in vitro conditions by food poisoned technique and also on sciarid larvae under in vivo conditions during Agaricus bisporus cultivation by giving 4 sprays stating at casing. Under in vitro studies dichlorvos (0.1%) and chlorpyriphos (0.1%) completely inhibited the growth of all edible fungi and cyromazin was found highly toxic to Lentinula edodes and Pleurotus ostreatus. Deacamethrin was found nontoxic to Lentinula edodes and Pleurotus ostreatus. Malathion for A. bisporus and Neemax (1.0%) was observed least toxic to all the edible fungi except L. edodes. Tunnelling index was found nil in mushroom fruit bodies when malathion was sprayed and yield was also marginally reduced over control. Highest yield (14.78kg) was recorded in case of decamethrin. Highest tunnelling index (4) was recorded in case of Neemax and lowest yield in chlorpyriphos.
