Farmers’ Perception Survey and Evaluation of Management Practices for Mango Fruit Borer (Citripestis Eutraphera)

Abstract

Mango fruit borer (MFB) is a significant pest that damages mango fruits and leaves. This study explores farmers’ perceptions of the mango fruit borer and evaluates management practices. Survey findings indicated that 48% of mango growers believed MFB attacks occur during April-May, while 30% identified May-June as the peak season. Additionally, 84% of mango growers believed MFB affects fruits, while only 2% think it also targeted leaves. Most mango growers (78%) preferred chemical methods to manage MFB, with 40% using bifenthrin, 28% using emamectin benzoate, and only 8% applying imidacloprid. Experiments evaluating MFB’s preference for different mango varieties revealed that nearly all commercial varieties had varying infestation levels. Sindhri was the most infested (29.9%), while Doseri was the least infested (12.6%). Light trap data suggested that the maximum moth population occurred during the last week of April. Evaluations of chemical pesticides showed that bifenthrin (250 ml / 100 L of water) was the most effective, while Thiamethoxam + Chlorantraniliprole (80 ml / 100 L of water) was the least effective for MFB. Emamectin benzoate, Chlorantraniliprole, and Lufenuron were better options than synthetic pyrethroids (Bifenthrin) because they were safer for natural enemies and pollinators. Integrated management strategies, such as installing one light trap per hectare and monitoring MFB on mango leaves and weeds in March/April for early detection, were recommended. Additionally, collecting fallen infested fruits and judicious use of insecticides can help mitigate losses caused by MFB.
