Interceptions of Bactrocera species in Austria
Several specimens of Bactrocera dorsalis sensu lato (Diptera: Tephritidae – EPPO A1 List) were trapped during surveys conducted in Austria in 2012-2018 (EPPO RS 2019/226) and considered to be linked to the entry of larvae with infested fruits. The official survey continued in 2019, and fruit fly traps combined with highly attractive lures were used in Vienna (14 sites) and all other Austrian provinces (27 sites). Seven adult individuals belonging to the Bactrocera dorsalis complex were trapped at 5 out of the 14 sampled sites in Vienna in 2019 (only urban areas). Six of these adult flies belong to Bactrocera dorsalis s.l. and one individual belongs to Bactrocera kandiensis (Diptera: Tephritidae – EPPO A1 List). One individual of Bactrocera zonata (Diptera: Tephritidae – EPPO A2 List) was trapped in one out of 14 sites in Vienna. All these findings are considered to be linked to the entry of larvae with infested fruits. As in previous years no specimens of B. dorsalis, B. zonata or B. kandiensis were caught in traps placed in the 27 sites of the other 8 Austrian provinces. These species were never found during surveillance of orchards.

The pest status of Bactrocera kandiensis in Austria is officially declared as: Absent, confirmed by survey.
The pest status of Bactrocera zonata in Austria is officially declared as: Absent.
