The Area-Wide Control Program (AWCP) was implemented in the Sikkim region to address the severe infestations of the Chinese citrus fly (Bactrocera minax) that significantly impact Mandarin (Citrus reticulata) plantations. The program also sought to increase farmer awareness about pest control strategies, empowering them to adopt integrated pest management practices for long-term sustainability. The long-term sustainability of the AWCP lies in its reliance on eco-friendly pest control methods and its ability to engage local farmers in the process. The pilot project, conducted in the Khamdong Block of Gangtok District, employed sustainable pest control methods, including protein baits combined with biological insecticides (Spinosad 45%) and the use of mimic traps for monitoring. Protein baits, which were combined with biological insecticides such as Spinosad 45%, were applied in the orchards. This research highlights the economic and ecological benefits of adopting integrated pest management (IPM) strategies, particularly in regions committed to organic farming. Despite challenges related to the region's terrain and weather conditions, the AWCP proved to be a cost-effective and environmentally sustainable solution. The use of chemical pesticides is not only restricted due to organic certification requirements but also due to the ecological sensitivity of the region. The program successfully reduced the Fruit Damage Rate (FDR) to approximately 20%, leading to increased yields and improved fruit quality in Mandarin. The study further explores the potential for scaling the AWCP to other regions and crops affected by similar pest infestations, emphasizing the long-term sustainability of such programs in enhancing the agricultural productivity

The data of this Area Wide Control Program shows that the application of protein bait solution reduced the average fruit drop rate and helped achieve managing of Chinese citrus fly in Sikkim Mandarin in Khamdong Block. The AWCP and orchard sanitation both the technical and managerial aspects run side by side for successfully reducing the Chinese citrus fly. Protein Bait (Great Fruit Fly Bait) solution is highly effective and convenient for area-wide application, it has an economical and ecological significance in the control of Chinese Citrus fruit fly. It can effectively increase farmer income with improved production efficiency and quality produce. It will result in better reduction of the pest infestation of CCF if applied every year. AWCP includes eco-friendly pest management measures in contrary to traditional blanket pesticide spray therefore it is economically viable and environmentally friendly due to its sustainable approach
