Interceptions of Bactrocera zonata in Austria
In Austria, Bactrocera zonata (Diptera: Tephritidae – EPPO A2 List) was caught in 2011 in a trap for Ceratitis capitata (Diptera: Tephritidae – EPPO A2 List) in Vienna. As part of a survey for Bactrocera species (EPPO RS 2019/226) conducted between 2012 and 2018, 12 adults of B. zonata were trapped at 3 sites in Vienna. All findings were in urban areas in Vienna. No specimens were found in fruits or traps in agricultural areas outside Vienna. Because the Austrian climate and environment are unsuitable for the establishment of B. zonata, and molecular sequencing has showed that the specimens caught were from genetically different origins, it is considered that the findings in Vienna are linked to repeated entries of larvae in infested fruit and not to an outbreak.
The pest status of Bactrocera zonata in Austria is officially declared as: Absent, confirmed by survey.
