A field study was designed to evaluate the efficacies of some bait sprays against fruit fly in comparison with a standard insecticide and a bait trap. ‘The bait spray of Malathion mixed with molasses significantly reduced (8.07%) fruit fly infestation by number and this was similar to Malathion cover spray (10.07%). However the bait spray with Diazinon + molasses, bait spray with Fenitrothion + molasses and bait trap with Malathion cover spray showed statistically similar effect on fruit infestation by weight. The maximum edible yield reduction per fruit was found in fruits with higher intensity of infestation at grade IV followed by grade Ⅲ, Ⅱ and I with 4, 3, 2 and 1 punctures per fruit, respectively.
