Cicadomorpha (Hemiptera) insects are currently responsible for a growing negative impact on the agricultural economy due to their ability to directly damage crops or through the capacity to act as vectors for plant pathogens. The phytopathogenic bacterium , the causal agent of Pierce's disease in vineyards, is exclusively transmitted by insects of this infraorder. Therefore, knowledge of the Cicadomorpha species and understanding their biology and ecology is crucial. In this work, in 2018 and 2019, the canopy and inter-row vegetation of 35 vineyards distributed in mainland Portugal were sampled to investigate species composition, richness, and diversity of the Cicadomorpha community, with a special focus given to vectors and potential vectors of . A total of 11,834 individuals were collected, 3003 in 2018 and 8831 in 2019. Of the 81 species/morphospecies identified, only five are considered vectors or potential vectors of this pathogen, namely, (Linnaeus, 1758), (Linnaeus, 1758), (Fallén, 1805), (Linnaeus, 1758), and (Linnaeus, 1758). was the most abundant xylem sap feeder, followed by . In addition, Cicadomorpha that cause direct damage to vines and vectors of grapevine yellows' phytoplasmas were also collected and identified in the sampled vineyards. The results suggested that vectors and potential vectors of and a large proportion of the population of Cicadomorpha have a positive correction with inter-row vegetation.
角蝉亚目（半翅目）昆虫目前对农业经济产生越来越大的负面影响，因为它们能够直接损害作物，或者通过充当植物病原体的传播媒介来造成危害。葡萄园中皮尔氏病的致病植物病原细菌仅由该亚目的昆虫传播。因此，了解角蝉亚目物种并掌握它们的生物学和生态学知识至关重要。在这项研究中，2018年和2019年对分布在葡萄牙大陆的35个葡萄园的树冠层和行间植被进行了采样，以调查角蝉亚目昆虫群落的物种组成、丰富度和多样性，特别关注葡萄皮尔氏病的传播媒介和潜在传播媒介。总共收集到11834只个体，2018年收集到3003只，2019年收集到8831只。在鉴定出的81个物种/形态物种中，只有5种被认为是这种病原体的传播媒介或潜在传播媒介，即黄斑黑蝉（林奈，1758年）、大青叶蝉（林奈，1758年）、葡萄斑叶蝉（法伦，1805年）、黑尾叶蝉（林奈，1758年）和二条黑尾叶蝉（林奈，1758年）。黄斑黑蝉是最丰富的木质部汁液取食者，其次是大青叶蝉。此外，在采样的葡萄园中还收集并鉴定出对角蝉亚目昆虫群落造成直接损害的物种以及葡萄黄化植原体的传播媒介。结果表明，葡萄皮尔氏病的传播媒介和潜在传播媒介以及很大一部分角蝉亚目昆虫种群与行间植被呈正相关。
