Abstract
The research was conducted from September to November 2025 using a method diagonal sampling in four villages: Matang Ara Jawa, Alue Sentang, Tanjung Neraca, and Simpang Lhee. The research was conducted with the aim of morphological identification of pests in the field and laboratory, as well as measurement of attack intensity and plant damage intensity. The results showed that two dominant rice stem borer species were found attacking rice plants in the study area, namely the yellow rice stem borer (Scirpophaga incertulas Walker) and the white rice stem borer (Scirpophaga innotata Walker). The highest damage intensity was recorded in Matang Ara Jawa Village at 27.52%, while the lowest was in Simpang Lhee Village at 16.75%, categorized as light to moderate damage. Linear regression analysis indicated a significant relationship between the stem borer population and the intensity of rice plant damage, expressed by the regression equation y = 0.0602x – 0.148. The model indicates that each additional larva predicts a 0.0602% increase in damage.
Rice stem borer pests are a plant pest that can cause serious damage to the growth and production of rice plants (Oryza sativa L.). This study aims to determine the species composition and intensity of rice stem borer attacks. This study was conducted from March to October 2025 in Poowo Village, Kabila District, Bone B...
