<p>RNA interference (RNAi) has emerged as a promising strategy for controlling insect pests, offering precise and environmentally sustainable alternatives to traditional pest control methods. By introducing double-stranded RNA (dsRNA) that specifically targets essential genes involved in pest survival, RNAi disrupts gene expression in target organisms. Various delivery methods, including topical application, transgenic plants, and nanoparticles, have been developed to enhance the effective administration of dsRNA. However, RNAi faces several challenges, including off-target effects, species-specific variations in efficacy, and the potential for resistance development. Despite these obstacles, ongoing research is focused on addressing these issues and improving the efficiency of RNAi-based pest control approaches. Future prospects for RNAi in insect pest management include advancements in delivery technologies, the identification of novel target genes, and the integration of RNAi with complementary pest control strategies. In conclusion, RNAi represents a potential long-term and targeted solution for insect pest control. Continued research and technological advancements are driving its adoption and expanding its application in agriculture and forestry globally. This review provides an in-depth analysis of RNAi mechanisms, evaluates current strategies, highlights the challenges faced, and explores the future directions for its use in insect pest management.</p>
