During the growing season 2022 we studied the phenology and the spatial and temporal distribution of Scaphoideus titanus, the main vector of the phytoplasma associated to the “Flavescence dorée” disease. The study was conducted in vineyards comprised in two areas of the municipality of Valdobbiadene (Treviso). The data confirmed the presence of aggregation spots of nymphs of S. titanus, and the prolonged occurrence of different development stages during the growing season.
Nel corso della stagione vegetativa 2022 è stato eseguito un monitoraggio nell’area di Valdobbiadene per rilevare la distribuzione spazio-temporale di Scaphoideus titanus e altri eventuali vettori di fitoplasmi. È stata creata una rete di punti sui quali venivano osservati campioni fogliari, trappole cromotropiche e esemplari caduti mediante frappage. I dati sono stati elaborati per individuare aree di aggregazione dei vettori che corrispondono a eventuali focolai.

Abstract
During the growing season 2022 we studied the phenology and the spatial and temporal distribution of Scaphoideus titanus, the main vector of the phytoplasma associated to the “Flavescence dorée” disease. The study was conducted in vineyards comprised in two areas of the municipality of Valdobbiadene (Treviso). The data confirmed the presence of aggregation spots of nymphs of S. titanus, and the prolonged occurrence of different development stages during the growing season.File | Dimensione | Formato | |
