Abstract : We examined the responses of oriental fruit flies, Bactrocera dorsalis, to the odours of different stages and types of fruit presented on potted trees in a field cage. Females were most attracted to odours of soft, ripe fruit. Odours of common guava were more attractive to females than pawpaw and starfruit (Averrhoa carambola), and equally as attractive as strawberry guava (Psidium cattleianum), orange, and mango. In field tests, McPhail traps baited with mango, common guava, and orange captured equal numbers of females. Traps baited with mango were compared with 2 commercially available fruit fly traps. McPhail traps baited with mango captured more females than visual fruit-mimicking sticky traps (Ladd traps) and equal numbers of females as McPhail traps baited with protein odours. Results from this study indicate that host fruit volatiles could be used as lures for capturing oriental fruit flies in orchards.
