dc.description.abstractThe present investigation was undertaken for management of phorid fly, Megaselia sandhui Disney by entomopathogenic nematoides on white button mushroom, Agaricus bisporus (Lange) Singer. The material for management comprised of phorid fly larvae, Galleria larvae, five EPN isolates, one insecticide. The experiments were carried out at Departments of Entomology, Nematology and Plant Pathology, CCS Haryana Agricultural University, Hisar during 2005-06 and CRD design with three replications was followed for layout. Out of 50 soil samples processed by “Insect trap” method five EPN isolates were collected. These were identified as Heterorhabditis indica (two isolates) and one isolate each of Steinernema abbasi, S. pakistanense and an unidentified species of Steinernema. In lab. tests, only Heterorhabditis indica (isolate II) resulted in significant mortality (60-87%) of M. sandhui larvae. Inoculum levels of 300, 400 and 500 were equally effective. H. indica (isolate I), S. pakistanense and S. abbasi also caused infections and larval mortalities, but the results were inconsistent and statistically non-significant. Steinernema sp. was totally ineffective. In vivo experiment using 3 levels of H. indica (isolate II) revealed lowest (5.3%) infestation in case of 10x104 IJs, followed by 5x104 IJs (7.1%) treatments of H. indica. Highest yield (24 kg/q compost) was obtained with H. indica @ 10x104 IJs, which was at par with 5x104 IJs (22.6 kg/q compost), but significantly higher than other treatments.en_US
