Studies on pest complex and efficacy of botanicals against major pest of Oyster Mushroom in Meghalaya / Badarikynti Nongkynrih - Umiam : CPGS, CAU, c2014 - [30], 84p. : ill., some col. ; - [Entomology, School of Crop Protection] .
The oyster mushroom is the second most important mushroom in production in the world, accounting for 25% of total world production of cultivated mushrooms. The damage caused by various insect pests has reduced the production of oyster mushroom to a large extent.The population of the pests fluctuates from season to season.Several times pesticide appications become mandatory for the management of these noxious pests. Therefore, experiments were carried out to study the pest complex, their population dynamics and toxicology of three most widely used bio-pesticides and an indigenous plant extract on the major pests of oyster mushroom. All the experiments were carried out in mushroom house, Division of Plant Pathology, IPM and Biological Control Laboratory, ICAR RC for NEH Region, Umiam at ambient conditions. Overall results revealed that several insect pests viz., pleasing fungus beetles ( Triplax spp., Scaphisoma spp., and Megalodacne spp.,) sciarid fly (Bradysia spp.), phorid fly (Megaselia spp.), fruitfly (Drosophila spp.), rove beetles (Staphylinus spp.), noctuid moth (Diomea rotunda), springtail (Lepidocyrtus spp.) and mites (Tyrophagus spp.) were found to infest oyster mushroom in Meghalaya. It was observed that the percent damage of harvested oyster mushroom due to these pests was highest during the summer months (May, June, July and August); where 100% damage was recorded, while minimal damage and infestation of the pests was observed during cold months. Biology studies have showed that Bradysia spp., Megaselia spp. and Triplax spp. took 19-23 days, 16-20 days and 20-22 days, respectively to complete their life cycle under laboratory conditions. Overall results on studies of toxicity of bio-pesticides against Bradysia spp. and Triplax spp. revealed that Anonin 1% EC and ethanol extract of Zanthoxylum armatum were found most toxic among all the tested bio-pesticides; which was found to cause quick and higher mortality of the two pest species. Neem 0.15 EC and Karanjan 2% EC were found to be moderately toxic to these insect pests.
