This thesis aims to investigate the phenology and the spatio-temporal distribution of Scaphoideus titanus, the main vector of Flavescence dorée phytoplasmas. The analysis was carried out by monitoring two viticultural areas located in two municipalities of the Treviso district: San Pietro di Feletto and Refrontolo. Monitoring was carried out during the 2022 growing season. There was a large presence of juvenile stages of the insect and several areas of aggregation within these areas; however, the presence of adults was low, suggesting the efficacy of vector control measures.
La presente tesi ha inteso analizzare la fenologia e la distribuzione spazio-temporale di Scaphoideus titanus, vettore del fitoplasma associato alla Flavescenza dorata della vite (FDp). L’analisi è stata svolta mediante monitoraggi puntuali effettuati in due aree viticole situate in due comuni della provincia di Treviso: San Pietro di Feletto (TV) e Refrontolo (TV). I monitoraggi sono stati svolti nel corso della stagione vegetativa 2022. All’interno delle due aree è stata rilevata una forte presenza di stadi giovanili dell’insetto e diverse aree di aggregazione; la presenza degli adulti è invece risultata limitata, indice di una buona efficacia delle strategie di controllo del vettore.

Abstract
This thesis aims to investigate the phenology and the spatio-temporal distribution of Scaphoideus titanus, the main vector of Flavescence dorée phytoplasmas. The analysis was carried out by monitoring two viticultural areas located in two municipalities of the Treviso district: San Pietro di Feletto and Refrontolo. Monitoring was carried out during the 2022 growing season. There was a large presence of juvenile stages of the insect and several areas of aggregation within these areas; however, the presence of adults was low, suggesting the efficacy of vector control measures.File | Dimensione | Formato | |
