Viticulture is one of the most important sectors of the Italian agricultural economy, but it is increasingly threatened by the introduction and spread of invasive alien phytophagous insects. Among these, Popillia japonica Newman stands out for its high invasive potential, polyphagous feeding habits, and ability to cause significant damage to several crops, including grapevine. This thesis analyzes the biological characteristics, geographical distribution, damage, and the main control strategies for this species, with particular emphasis on viticulture. A further section focuses on the economic impact of the infestation, highlighting the increase in management costs, production losses, and the need for timely and integrated pest management strategies. The findings confirm that Popillia japonica represents a serious threat to viticulture, making it essential to adopt a pest management approach based on prevention, continuous monitoring, and the integration of multiple control methods in order to ensure both productive and environmental sustainability.
La viticoltura rappresenta un comparto di primaria importanza per l’economia agricola italiana, ma è sempre più esposta ai rischi derivanti dall’introduzione e dalla diffusione di fitofagi alloctoni. Tra questi, Popillia japonica Newman, si distingue per l’elevato potenziale invasivo, la polifagia e la capacità di arrecare danni significativi a diverse colture, compresa la vite. La presente tesi analizza le caratteristiche biologiche, la diffusione geografica, i danni e le principali strategie di contenimento di questa specie, con particolare attenzione al contesto viticolo. Un’ulteriore sezione è dedicata all’impatto economico dell’infestazione, evidenziando l’aumento dei costi di gestione, le perdite produttive e la necessità di strategie integrate e tempestive. I risultati dell’analisi confermano che Popillia japonica costituisce una minaccia concreta per la viticoltura, rendendo indispensabile un modello di difesa basato su prevenzione, monitoraggio costante e integrazione di più strumenti di controllo, in un’ottica di sostenibilità produttiva e ambientale.

Abstract
Viticulture is one of the most important sectors of the Italian agricultural economy, but it is increasingly threatened by the introduction and spread of invasive alien phytophagous insects. Among these, Popillia japonica Newman stands out for its high invasive potential, polyphagous feeding habits, and ability to cause significant damage to several crops, including grapevine. This thesis analyzes the biological characteristics, geographical distribution, damage, and the main control strategies for this species, with particular emphasis on viticulture. A further section focuses on the economic impact of the infestation, highlighting the increase in management costs, production losses, and the need for timely and integrated pest management strategies. The findings confirm that Popillia japonica represents a serious threat to viticulture, making it essential to adopt a pest management approach based on prevention, continuous monitoring, and the integration of multiple control methods in order to ensure both productive and environmental sustainability.| File | Dimensione | Formato | |
