EPPO Reporting Service (2009/182) : it was first observed in 1929 on bark samples collected from branches of Castanea crenata in the Beira Interior Province. These initial infections were probably successfully eradicated, as no further reports were made until 1989 when two outbreaks were found on C. sativa in the Trás-os-Montes province (which is the main chestnut-growing area in Portugal). In recent surveys, C. parasitica was detected across four mainland provinces (Minho, Trás-os-Montes, Beira Interior, Alentejo), Azores (Pico, San Miguel, Terceira) and Madeira.
