Incursion of Bactrocera dorsalis in Spain
The NPPO of Spain recently informed the EPPO Secretariat of the first finding of Bactrocera dorsalis (Diptera: Tephritidae – EPPO A1 List) on its territory. In October 2025, three adults of B. dorsalis were caught in a trap located in an orchard in El Astillero municipality (Cantabria). The identity of the species was confirmed as Bactrocera dorsalis by the Regional Laboratory. Official phytosanitary measures have been implemented including intensive surveillance and safe disposal of any fallen fruit from host plants within a 500 m radius of the original trap. According to an assessment on B. dorsalis by EFSA (2025), the NPPO of Spain does not believe that B. dorsalis can establish in Cantabria. The source of the outbreak is not known but the NPPO notes that several entry points are located in the vicinity (a wholesale market, the port and airport of Santander).
The pest status of Bactrocera dorsalis in Spain is officially declared as: Transient, actionable, under eradication.
