The thesis studies the effectiveness of different phytosanitary treatments in controlling the presence of Scaphoideus titanus, the vector parasite of Flavescence dorée of grapevine, using longitudinal data collected by CREA from experimental vineyards. A marginal model with a hierarchical structure based on generalized mixed effects models (GLMM) was built to estimate the average effect of the treatment, taking into account intra-vineyard dependence and inter-annual variability. The GLM model and the marginal model were also developed and compared.
La tesi studia l'efficacia di diversi trattamenti fitosanitari nel controllare la presenza di Scaphoideus titanus, il parassita vettore della Flavescenza dorata della vite, utilizzando dati longitudinali raccolti dal CREA da vigneti sperimentali. È stato costruito un modello marginale con una struttura gerarchica basata su modelli a effetti misti generalizzati (GLMM) per stimare l'effetto medio del trattamento, tenendo conto della dipendenza intra-vigna e della variabilità inter-annuale. Sono stati sviluppati e confrontati anche il modello GLM e il modello marginale.

Abstract
The thesis studies the effectiveness of different phytosanitary treatments in controlling the presence of Scaphoideus titanus, the vector parasite of Flavescence dorée of grapevine, using longitudinal data collected by CREA from experimental vineyards. A marginal model with a hierarchical structure based on generalized mixed effects models (GLMM) was built to estimate the average effect of the treatment, taking into account intra-vineyard dependence and inter-annual variability. The GLM model and the marginal model were also developed and compared.| File | Dimensione | Formato | |
