The mango (Mangifera indica L.), a highly valued tropical fruit, faces significant production challenges due to various factors, including insect pests like fruit flies. In Nepal, mango farming spans 43,689 hectares with an average yield of 12.61 metric tons per hectare. Low productivity stems from pests, diseases, climate change, and inadequate infrastructure. Fruit flies, particularly detrimental to mango production, necessitate long-term solutions for effective control. This study, conducted on the Amarpali variety of mango at NARC, Tarahara, Sunsari, aimed to evaluate the impact of pheromone trap heights on mango fruit fly captures. Utilizing a Randomized Complete Block Design (RCBD), traps were placed at varying heights (2-7 feet) and monitored weekly. Results revealed that traps at 5 feet (T4) consistently captured the highest number of fruit flies, indicating this height aligns with the flies’ natural behavior within the tree canopy. Conversely, traps at 7 feet (T6) recorded the lowest captures. The findings suggest that placing methyl eugenol pheromone traps at 5 feet is optimal for monitoring and controlling mango fruit fly populations. This recommendation offers a practical solution for farmers in Sunsari and similar regions to enhance pest management, thereby improving mango yield and economic benefits, particularly for those cultivating the Amarpali variety.
