Top of page Bactrocera dorsalis is a member of the Oriental fruit fly B. This species complex forms a group within the subgenus Bactrocera and the name may therefore be cited as Bactrocera Bactrocera dorsalis. Native range of true B. Bactrocera invadens was later described by Drew et al. Bactrocera philippinensis was designated a synonym of B. This resulted in the synonymization of B. Records of B. Description Top of page Eggs The eggs of Bactrocera oleae were described in detail by Margaritis and those of other species are probably very similar.
They are 0. The chorion is reticulate requires scanning electron microscope examination. Creeping welts with small, stout spinules, with one posterior row of spinules larger and stouter than remainder. A8 rounded with prominent intermediate areas and obvious sensilla. Anterior spiracles: tubules. Posterior spiracles: spiracular slits thick walled, approximately 2.
Spiracular hairs just longer than a spiracular slit; dorsal and ventral bundles with broad, flat hairs, branched apically; lateral bundles with similarly shaped hairs. The inner rows of spinules stout, slightly curved, sharply pointed becoming larger just below the anal opening, outer rows with smaller spinules.
Puparium Barrel-shaped with most larval features unrecognisable, the exception being the anterior and posterior spiracles, which are little changed by pupariation. White to yellow-brown. Adults Drew and Hancock distinguish the B. Scutum generally black with lateral vittae present and medial vitta absent; yellow scutellum, except for basal band which is usually very narrow; abdomen with a medial dark stripe on T3-T5; dark laterally but form of marking varies from species to species.
It is noteworthy that colour of scutum varies in B. Populations from the Indian subcontinent and Africa have extensive pale markings Leblanc et al. When B. The distribution and invasion history of B. Whether or not B. The distribution of B. An interactive distribution map for B.
