Sumedang Regency in Indonesia is a significant mango production hub, but it faces challenges from fruit fly pests that cause yield loss and chemical residue issues, potentially leading to rejection of mangoes in international markets. Despite farmers' efforts, the pest control is ineffective and results in a loss of 30-40% of fruits. To address this, the West Java-based Center for the Protection of Food Crops and Horticulture (BPTPH) has implemented the Regional Scale Fruit Flies OPT Control Management System (Simpok) since 2018, covering 400 hectares across three regions. The system aims to reduce fruit fly populations and enhance the quality and competitiveness of the gedong gincu mango variety by monitoring, manufacturing, and applying protein baits, among other strategies. The results show a notable decrease in fruit fly populations after 1.5 years of implementation.
