Crop losses caused by the plant pathogenic bacterium ' Phytoplasma solani' (CaPsol) underscore the need to better understand its perplexing epidemiological pathways. (Hemiptera, Cixiidae) is a prominent CaPsol vector with three plant associations in Serbia (/HobsUd; /HobsCa; /HobsCf). Another cixiid planthopper, (Dufour), has been recently confirmed as a noteworthy CaPsol vector. A multi-test study assessed the relevance of associations and populations from and in CaPsol occurrence in sugar beet, maize, and tobacco. Molecular typing of the CaPsol strains transmitted to test plants in experimental trials provided the first evidence of HobsUd transmitting CaPsol tuf-a type to sugar beet, HobsCa infecting maize and tobacco with tuf-b type, and HobsCf transmitting CaPsol tuf-b to maize. Affiliation of with the specific CaPsol genotype, dSTOLg, was reaffirmed in this study. The possible involvement of in maize redness disease and tobacco stolbur was suggested, given that this cixiid was identified as a vector of CaPsol to these crops. The obtained results indicate that the tested vectors pose a threat to cultivated plants in Serbia, underscoring the need to recognize their relevance in CaPsol disease occurrences.
由植物致病细菌“茄植原体”（CaPsol）导致的作物损失凸显了更好地了解其复杂流行病学途径的必要性。（半翅目，角蝉科）是塞尔维亚一种重要的CaPsol传播媒介，与三种植物有关联（/HobsUd；/HobsCa；/HobsCf）。另一种角蝉科飞虱，（杜福尔），最近已被确认为一种值得关注的CaPsol传播媒介。一项多测试研究评估了来自和的关联以及种群在甜菜、玉米和烟草中CaPsol发生情况中的相关性。在实验中对传播到试验植物上的CaPsol菌株进行分子分型，首次证明了HobsUd将CaPsol tuf-a型传播给甜菜，HobsCa用tuf-b型感染玉米和烟草，以及HobsCf将CaPsol tuf-b型传播给玉米。在本研究中再次确认了与特定CaPsol基因型dSTOLg的关联。鉴于这种角蝉科飞虱被确定为CaPsol传播到这些作物的媒介，因此有人提出它可能与玉米发红病和烟草矮化病有关。所得结果表明，所测试的传播媒介对塞尔维亚的栽培植物构成威胁，凸显了认识它们在CaPsol病害发生中的相关性的必要性。
