(Wagner, 1961) (Hemiptera: Triozidae): The Prevalent Psyllid Species in Leek Fields of Northwestern Spain.

(Wagner, 1961) (Hemiptera: Triozidae), the onion and leek psyllid, belongs to the Förster complex, along with and . In contrast to the other two species, there has been a notable absence of studies examining the distribution and seasonal occurrence of , despite its association with significant issues in leek crops. Surveys were conducted between 2017 and 2020 in the main leek-growing area of Castile and Leon (Spain).

Survey of Liberibacter Solanacearum and Its Associated Vectors in Potato Crop in Spain.

' Liberibacter solanacearum' (CaLsol), the etiological agent of potato zebra chip (ZC), is transmitted to potato plants by the psyllid (Šulc, 1909) in North and Central America and New Zealand. The risk of the dispersion of ZC in Spain depends on the presence of an efficient vector. This work studies the presence and abundance of ZC symptoms and CaLsol in potato plants, as well as the presence and abundance of psyllid species associated with potato crops in the main producing areas in Spain.
