Update on the situation of Trioza erytreae in Portugal
In mainland Portugal, Trioza erytreae (Hemiptera: Triozidae – EPPO A2 List, vector of huanglongbing) was first found in the region of Porto in January 2015 (EPPO RS 2015/204). Subsequent official surveys (yellow sticky traps and observation of leaf galls) have shown that the pest currently occurs in a total of 36 municipalities (corresponding to a total of 178 parishes) in the Norte and Centro regions. A detailed map of demarcated areas can be viewed on the DGAV website. During these surveys, samples were also collected and tested for ‘Candidatus Liberibacter spp.’ to verify the absence of huanglongbing. Phytosanitary measures have been taken to eradicate T. erytreae.
The pest status of Trioza erytreae in Portugal is officially declared as: Present, under eradication.
