L’uso degli oli essenziali per la lotta agli infestanti delle derrate alimentari si rivela un’alternativa promettente agli insetticidi chimici. Questa tesi raccoglie gli studi effettuati mettendo in luce vantaggi e svantaggi del loro utilizzo, le modalità d’azione e le tecnologie usate. Gli oli essenziali si sono rilevati efficaci e vantaggiosi in termini di sostenibilità ed efficacia, mostrando però problematicità dovute alla loro variabilità chimica nel tempo, all’odore e alla possibile resistenza che potrebbero indurre. Esercitano la loro efficacia attraverso meccanismi come l'inibizione di enzimi chiave e la riduzione della detossificazione nei parassiti, aumentando così la loro azione insetticida. Tecnologie innovative, come le nanoemulsioni, sono state sviluppate per migliorare la solubilità e la stabilità degli oli essenziali, ottimizzando la loro applicazione. Tuttavia, la commercializzazione di biopesticidi a base di oli essenziali è ostacolata dalla complessità nella standardizzazione e dai processi di approvazione.

Abstract
The use of essential oils for controlling food pests represent a promising alternative to conventional chemical pesticides. This thesis collects the studies carried out highlighting the advantages and disadvantages of their use, the methods of action and the technologies used. Essential oils have proven to be effective and advantageous in terms of sustainability and effectiveness, however they present some problems due to their chemical variability over time, the odor and the possible resistance they could induce. They exert their efficacy through mechanisms such as the inhibition of key enzymes and the reduction of detoxification in pests, thus increasing their insecticidal action. Innovative technologies, such as nanoemulsions, have been developed to improve the solubility and stability of essential oils, optimizing their application. However, the commercialization of essential oil-based biopesticides is hampered by the complexity of standardization and approval processes.File | Dimensione | Formato | |
