D. kuriphilus dispersion

Sampling campaigns were carried out in Galicia since 2014 by Estación Fitopatolóxica Areeiro (EFA, Deputación de Pontevedra) in collaboration with SEAGA, a public company related to Consellería do Medio Rural (Xunta de Galicia). Main initial criteria for campaign design were D. kuriphilus personal and authority reports (i.e. infested and neighbouring areas) and high chestnut fruit production locations. Sampling radius and transected areas were progressively increased as more infested areas were detected. We have as well taken advantage of ongoing sampling campaigns of different plant species to sample Castanea spp. too.
