Percentage of Erionota thrax Attacks on Barangan, Ambon, and Rattan Bananas in South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Erionota thrax (L.) is a major pest of banana plants, with damage reaching up to 60%. This study aimed to identify the percentage of leaf damage caused by E. thrax in three banana cultivars: Barangan, Ambon, and Rotan in South Sumatra. This research was conducted using survey and mapping methods by determining coordinate points, specifically the affected plants, and then observing the area around symptomatic plants within a 50-meter radius. The Timestamp application was used for documenting the E. thrax pest. The research results show that E. thax attacks vary across regions and banana varieties. The highest percentage of leaf roller attack rates was found in Muratara Regency, reaching (50%), while the lowest percentage of leaf roller attacks was found in Prabumulih, only reaching (1.06%). The results show that the percentage of Rotan and Barangan bananas is more resistant to the leaf roller pest E. thrax and is not attacked by the banana leaf roller (0%), while the attack percentage on Ambon bananas reaches (50%). This indicates that each type or variety of banana has a different level of resistance, and the environment also affects the level of attack. This attack distribution map can serve as a basis for developing more precise pest control strategies. Selecting cultivars like Banana Rotan is an effective strategy to reduce banana production losses in South Sumatra.]]>
