Abstract : A field experiment was conducted in Maharashtra, India during 1998, 1999 and 2001 to evaluate the yield loss in mango cv. Alfonso caused by the mango hopper (Idioscopus niveosparsus). Monocrotophos was applied at 1, 2 and 3 sprays as individual treatments, during panicle emergence stage and at subsequent 15-day intervals. The hopper population was 6.71 and 8.5/panicle in 2 and 3 sprays, respectively, which was significantly less than the untreated control. Approximately 46.30 and 41.09% increase in yield was observed over the control, with 2 and 3 sprays, respectively. Two sprays applied first at panicle emergence and second at 15 days after the first spray were effective.
