| Abstract: | We report the first widespread survey of tephritid fruit flies attempted in a single time period. 1,471 cue lure traps caught 17 species, and extensions to previously recorded geographical ranges were detected for seven of them: Bactrocera tryoni, B. neohumeralis, B. frauenfeldi, B. aeroginosa, Dacus absonifascies, D. aequalis and D. newmani. the traps also unexpectedly caught several B. cacuminata and also both males and females of Dirioxa pornia and Ceratitis capitata. the geographical variation in the relative abundance of B. tryoni and B. neohumeralis in the region of their co-occurrence was in substantial agreement with earlier estimates. the regional variation in abundance of B. tryoni in the eastern states was in accordance with the predictions of a published bioclimatic model. Furthermore, the spread of this species (expected from the model) to several locations in the Northern Territory is recorded here for the first time. |
