Abstract
The occurrence of white stem borer (Scirpophaga innotata Walker) in relation with other insect pest and natural enemies in the irrigated and rainfed lowland ricefields in Agusan del Norte was studied for two cropping seasons. Seasonal abunance of the white stem borer and associated arthropods were determined through sweep net, quadrat, and pan sampling in 12 individual harvest. There were three generations of white stem borer recorded during the survey as shown by the occurence of egg masses althought overlapping of generations was also noted. However, its population fluctuated as the crop matured.
