Host plants and vectors of grapevine Flavescence dorée phytoplasmaKseniia Annenkova, 2024, research project (high school)
Abstract: Understanding the epidemiology of Flavescence dorée (FD), a devastating grapevine disease caused by the phytoplasma (FDp), is crucial for developing effective management strategies. This study aimed to provide a comprehensive overview of the host plants and vectors of FDp. Key methods included a review of existing literature and analysis of genetic data to identify potential transmission pathways. The results revealed that FDp infects a wide range of plant species beyond grapevines, complicating control measures. While the leafhopper Scaphoideus titanus is the primary vector, several occasional vectors such as Orientus ishidae, Dictyophara europaea, Phlogotettix cyclops etc. also play roles in transmission. The study identified 22 map genotypes of the 16SrV phytoplasma, categorized into three main clusters (Map-FD1, Map-FD2, and Map-FD3), which are primarily associated with S. titanus and grapevine. The research emphasizes the importance of ongoing studies to further understand the geographic distribution and genotypic variability of FDp, which is crucial for refining control strategies and ensuring their success. Enhanced knowledge of FDp genotypes and their interactions with different vectors and host plants will help in improving targeted and effective disease management interventions.
