Abstract : Crop losses due to fruit fly (B. correcta) infestation in some locally preferred mango cultivars were assessed at AES, Paria, Gujarat, India, during 1996-99. Fruit fly infestation (26.66%) and its larval population (2.73 larvae/damaged fruit) were significantly higher in cultivar 'Alphonso' than in 'Kesar', 'Rajapuri', and 'Dasheri'. Out of a hundred randomly selected fruits/trees in each cultivar, Alphonso suffered the maximum weight loss (6.58 kg), while minimum weight loss was recorded from Dasheri (1.43 kg). Similarly, the highest economic loss was in Alphonso (Rs. 49.37) followed by Kesar (Rs. 26.65) and the lowest was in Dasheri (Rs. 7.16).
