Abstract

Screening, seasonal activity and management studies of mango leaf webber, Orthaga euadrusalis Hampson, (Pyralidae : lepidoptera) carried out at Fruit Research Station (FRS), Entkhedi, The least susceptible varieties were Chinnarasm, Piddarasm, Bombaygreen, Malda, Sindhuri and Alphanjo. While the most susceptible varieties were Mango Glass, Dahiyar, Temuria and Langrah. Significantly higher infestation was recorded in varieties had higher and dense tree canopy (r value = 0.838). Pest remained active in mango orchard from June to December and completed different over lapping generations during this period.Mechanical removal in early part of the season spot treatment with Imidacloprid (0.02%) and application of insect growth regulator Diflubenzuron were found effective and most feasible for the management of mango leaf webber.
