Most studies in this field have relied on single-method approaches, which are prone to overconfidence and lack sufficient validation across repeated trials, raising concerns about their robustness. To address these limitations, this research explores the use of polysaccharide encapsulation as a sustainable and efficient strategy for controlling insect pests in food storage, with a focus on enhancing the stability and efficacy of essential oil-based treatments. Myrtus communis essential oil was primarily composed of α-pinene (43.94%). Encapsulation efficiency reached 35.7%, with a loading capacity of 3.65%. The encapsulated oil caused 100% mortality and complete emergence inhibition in C. ferrugineus adults. Date kernel solution showed moderate attractancy (Class III), while the essential oil and microcapsules performed better (Class IV). Encapsulated oils minimally affected semolina properties, whereas crude oil reduced protein by 2.32%, decreased ash by 10.98%, and increased moisture by 2.56% after 45 days. This study highlights an innovative and sustainable approach for valorizing date pit waste by extracting polysaccharides and incorporating them into encapsulation processes, offering a dual benefit of waste management and the development of eco-friendly bio-pesticides. This strategy provides a practical solution for formulating effective pest control agents, demonstrating the potential of resource-efficient practices in agricultural applications.
