Il presente elaborato analizza l’impiego della tecnologia a RNA interferente (RNAi) quale alternativa sostenibile ai fumiganti di sintesi, in linea con le strategie europee Farm to Fork e Green Deal che prevedono crescenti restrizioni normative sull’uso dei pesticidi nell’Unione Europea. L’obiettivo centrale dello studio è valutare l’applicabilità del silenziamento genico tramite dsRNA nella protezione dei prodotti cerealicoli, con un focus specifico sulla gestione di Tribolium castaneum. Nella prima parte del lavoro, viene esaminato il pathway molecolare dell'RNAi e le basi biologiche che rendono tale insetto un modello ideale per il silenziamento sistemico. Successivamente, vengono analizzati i vantaggi in termini di biosicurezza e specificità d’azione, affrontando al contempo le barriere fisiologiche e biochimiche che ne condizionano l'efficacia. In conclusione, l'analisi evidenzia il potenziale dell’RNAi come strumento di precisione per la difesa delle derrate, sottolineandone i vantaggi in termini di biosicurezza alimentare e le criticita’ tecniche che ne ostacolano l’applicazione su larga scala.

Abstract
This paper analyzes the use of RNAi technology as a sustainable alternative to synthetic fumigants, in line with the European Farm to Fork and Green Deal strategies, which entail increasing regulatory restrictions on pesticide use in the European Union. The central objective of the study is to evaluate the applicability of dsRNA gene silencing in the protection of cereal crops, with a specific focus on the management of Tribolium castaneum. The first part examines the molecular pathway of RNAi and the biological basis that makes this insect an ideal model for systemic silencing. Subsequently, the advantages in terms of biosafety and specificity of action are analyzed, while addressing the physiological and biochemical barriers that limit its effectiveness. Ultimately, the analysis underscores the potential of RNAi as a precision tool for food protection, emphasizing its advantages in terms of food safety and the technical challenges that hinder its large-scale application.| File | Dimensione | Formato | |
