Abstract

To determine a period for pest control, we surveyed the occurrence patterns of Scotinophara lurida in eco-friendly paddy fields between 2023 and 2024. The surveys were conducted once a week at two sites in Jeollanam-do, Yeosu Hwayang-myeon and Gokseong Seokgok-myeon, with three replicates per site. Monitoring began when rice planting was complete and continued until harvest. The overwintered generation of S. lurida first appeared between the second (June 8, 2023) and fourth (June 29, 2023) weeks after the rice transplantation was complete. Peak adult populations were recorded between the sixth (July 6, 2023) and seventh weeks (July 13, 2023, and July 25, 2024) after transplanting. The second generation of adults emerged between 10 (August 15, 2024) and 12 weeks (August 17, 2023) after transplanting and then moved to overwintering sites in early September, shortly following the highest occurrence peak. Based on the occurrence patterns of S. lurida, we suggest that control measures for S. lurida using eco-friendly agents or attractants be timed appropriately.
