' 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. Eighty-eight plots were surveyed punctually to detect ZC symptoms and psyllid species in the main potato-producing areas. Furthermore, fourteen potato plots were surveyed by different sampling methods during the cropping season to detect psyllid species from 2016 to 2018. Very few symptomatic and CaLsol-positive plants were detected in Mainland Spain, and any positive plant was detected in the Canary Islands. Most of the adult psyllids captured were identified as (Foerster, 1848), and some of them as , but no was detected. was found widely distributed in the northern half of the Iberian Peninsula; however, this psyllid does not seem sufficient to pose a threat to potato production, due to the scarce number of specimens and because the frequency of specimens that were CaLsol+ was very low.
番茄刺皮瘿蚊（CaLsol）是马铃薯斑马薯片病（ZC）的病原体，在北美、中美洲和新西兰，它由木虱（Šulc，1909）传播给马铃薯植株。在西班牙，ZC扩散的风险取决于是否存在有效的传播媒介。这项研究调查了西班牙主要产区马铃薯植株上ZC症状和CaLsol的出现情况及丰度，以及与马铃薯作物相关的木虱种类的出现情况及丰度。对88个地块进行了定点调查，以检测主要马铃薯产区的ZC症状和木虱种类。此外，在2016年至2018年的种植季节，通过不同的采样方法对14个马铃薯地块进行了调查，以检测木虱种类。在西班牙大陆检测到的有症状且CaLsol呈阳性的植株极少，在加那利群岛未检测到任何阳性植株。捕获的成年木虱大多被鉴定为（Foerster，1848），其中一些被鉴定为，但未检测到。在伊比利亚半岛北半部广泛分布；然而，由于样本数量稀少且CaLsol呈阳性的样本频率很低，这种木虱似乎不足以对马铃薯生产构成威胁。
