Abstract : Choice responses of oriental fruit fly, Dacus dorsalis [Bactrocera dorsalis] adults (immatures and matures) at different time (5, 10, 15, 20, 30, 40, 50 and 60 min) to the volatiles from intact mango fruits at different doses (250, 500, 750 and 1000 g), and that from mango pulps at different doses (0.01, 0.1, 1.0, 10 g) were bioassayed by using Y-Tube olfactometer in the laboratory, respectively. The results showed that the both sexes of adults including immatures and matures could respond significantly to the volatiles from mango pulps but not to that from intact mango fruits. Dose-response indicated that the adults were more attracted when the dose of mango pulps was increased. Time-response mean that the adults became more and more attracted to the volatiles from mango pulps when testing time progressed from the 5th min to the 60th min. It was also confirmed that sexually immature adults were more physiologically sensitive to the volatiles from mango pulps than sexually mature adults, and females were more sensitive to the volatiles than males.
