Field experiments were conducted to assess the extent of losses occurring in rice crop due to the white stem borer (WSB) Scirpophaga fusciflua (Hampson) at different stages of crop growth. Results revealed that maximum infestation in terms of deadhearts and white ears was 11.6% at maximum release level (6 larvae/hill) and the least (6.2%) at 2 larvae/hill. The avoidable losses varied from 7.5 to 32.3%. The infestation % of released larvae was lowest to the economic threshold level.
