Stem borer is one of the main pests of lowland rice in South Sulawesi. Types of stem borer found include white stem borer (Scirpophaga innotata, yellow stem borer (S. incertulas), and striped stem borer (Chilo suppressalis) and red rice stem borer guava (Sesamia inferens (Walker). The four types of stem borer pests that most attack and cause damage to lowland rice in South Sulawesi are white stem borer (S. innotata). This study aims to determine the best agroecosystem model for the management of rice stem borer in South Sulawesi. Inventory research on the level of damage and insecticide use in stem borer is carried out in 2018/2019 spread in four districts, namely Wajo, Sidrap, Maros, and Barru regencies. The combine between cropping system with planting times are 5 treatments and farmers as replications (3 replications). The treatments are monoculture with 2 planting times year -1 in Sidrap Regency, monoculture with 1 planting times year -1 (Wajo District), polyculture with 3 planting times in Maros Regency, polar vegetation with 2 planting times year -1 (Barru Regency), polyculture with 1 planting times year -1 (Pangkep Regency). The results showed that the highest level of attack of rice stem borer was found on monoculture with 2 planting times year -1 (38.25%), then followed by polyculture vegetation with 3 times year -1 (31.12%), monoculture with 1 planting times year -1 (20.32%), and polyculture with 2 planting times year -1 (15.68%), and polyculture with 1 planting times year -1 (6.59%). The lowest use of insecticides is found in polyculture with 1 planting times year -1 (1.10 l ha -1 per season) and the highest in monoculars with 2 planting times year -1 (5.5 l ha -1 per season).
