Updated situation of Trioza erytreae in Spain
In Spain, the first signs of the presence of Trioza erytreae (Hemiptera: Triozidae – EPPO A2 List, vector of huanglongbing) were seen in August 2014 on lemon trees (Citrus limon) in Vilanova de Arousa (province of Pontevedra, Galicia) and the identity of the pest was later confirmed (EPPO RS 2015/022). Further surveys detected T. erytreae in the municipalities of Cambados, Cangas, Illa de Arousa, O Grove, Poio, Pontevedra, Sanxenxo, Vilagarcía de Arousa, (province of Pontevedra), as well as in Boiro, Padrón and Rianxo (province of La Coruña, also in Galicia). A large majority of positive samples have been collected from lemon trees (C. limon), but a small number have been collected from orange trees (C. sinensis). On all sites where T. erytreae specimens were found, additional plant samples were collected and tested for the presence of ‘Candidatus Liberibacter spp.’ that are associated with huanglongbing. All results were negative. It is recalled that measures are being taken to prevent the spread of T. erytreae in Spain.
