Mechanical egg mass removal: an effective strategy for managing white stem borer
Issue Date

Abstract
White stem borer (WSB), Scirpophaga innotata Walker, is one of the most serious pests of rice in irrigated and rainfed environments in Agusan del Norte. High levels of WSB infestation may result in tremendous yield losses estimated at 50 to 60% or even higher during pest outbreak. The effectiveness of mechanical egg mass removal in managing WSB was evaluated in the experimental area of PhilRice Agusan and in selected farmers' fields for four cropping seasons (2002-2003). Mechanical removal of egg masses in the field significantly reduced WSB damage resulting in yield and income higher than those in the insecticide-treated and untreated fields. Yield decreased as the degree of WSB damage (%whiteheads) in PSB Rc82 rice variety increased.
