The peach fruit ny, Bactrocera ZOllala attacks many hosts in Egypt. Studies were carried out to determine host preference of B. ZOllala among different hosts (peach. apricot, apple, mango, guava and citrus) in five districts at Sharkia Governorate. The total mean numbers of captured male flies using pheromone traps (distributed in each orchard) were counted. The data obtained showed that there were highly significant variations between hosts. The apple fruits were the most preferable tested host (52.23 - 158.84 flies 110 trap) followed by peach & mango (42.00 - 151.11 flies I HI trap) and apricot & guava (36.9 - 147.0 flies I 10 trap). The citrus fruits recorded the least attractant host (35.31 - 80.5 fliesl 10 trap). Also,. the preferability was varied significantly from one district to another, where Abo-hammad, belbeis and Faquse represented the highest district of infestation (62.36 - 158.84 flies I 10 trap), while Menia Elkamh and Elsalhia represented the lowest district of infestation (33.72- 91.00 flies 110 trap) on different tested hosts.
