dc.description.abstractThe onset of Trioza erytreae, the African citrus psyllid, in the northwest of the Iberian Peninsula (north of Portugal and northwest of Spain) caused great concern among citrus growers in Europe. This insect is a vector of the bacteria Candidatus Liberibacter spp., the causal agent of huanglongbing, one of the most devastating citrus diseases. The first report of T. erytreae presence in mainland Europe refers to an area with isolated citrus trees and no significant citrus orchards. However, it was predictable that T. erytreae could spread quickly reaching the most important citrus growing area, in the south. Therefore, the Portuguese citrus industry is the first to be threatened in Europe, but the entire European citrus industry is at risk. In addition to the containment measures taken by the Portuguese and Spanish Phytosanitary Services, several models were made to predict how the African citrus psyllid could advance through the territory of the two countries. Releases of the parasitoid Tamarixia dryi were used for psyllid control. Despite that, T. erytreae has moved south and is on the verge of reaching the most important Portuguese citrus-producing area, which is connected to the citrus-growing areas of the other Mediterranean countries. This advance took place along the coast, without reaching interior regions of the country, where, according to some models, a high-water vapor pressure deficit hinders the insect's development in warmer areas. Populations of T. erytreae dropped significantly in 2021 and 2022, making it difficult to detect even in previously infested areas. This doesn't give farmers peace of mind because the presence of T. erytreae, even in low populations, could lead to a quick spread of huanglongbing, if or when the disease arrives in Europe. Therefore, it is crucial to continue to monitor T. erytreae populations and implement the necessary containment measures for the vector.pt_PT
