Bactrocera dorsalis is a species of tephritid fruit fly that is endemic to Southeast Asia, but has also been introduced to Hawai'i, the Mariana Islands and Tahiti. It is one of the major pest species in the genus Bactrocera with a broad host range of cultivated and wild fruits, second in damage only to B. papayae.[1]

It is similar to the closely related species B. carambolae, B. papayae, B. occipitalis, B. philippinensis and B. invadens in color pattern. In reality, recent scientific evidence showed that B. papayae, B. invadens and B. philippinensis belong to the same biological species as B. dorsalis.[2]

Males of the species respond strongly to methyl eugenol and this is used for monitoring and estimating populations.[3] [4] They are also important pollinators/visitors of wild orchids, Bulbophyllum cheiri and Bulbophyllum vinaceum, in Southeast Asia, which lure the flies using methyl eugenol.[5][6]
