摘要

Mosquito-borne diseases represent a growing global health crisis, exacerbated by climate change and insecticide resistance. RNA interference (RNAi), a natural mechanism of gene silencing, offers a promising, target-specific alternative for mosquito control. This review explores the potential of RNAi to disrupt critical physiological processes, such as reproduction and disease transmission, thereby reducing vector populations and competence. We examine the mechanisms of RNAi, its application in combatting insecticide resistance, and recent advancements in delivery systems, including nanobody- and chitosan-based nanoparticles, which enhance the stability and uptake of double-stranded RNA (dsRNA) molecules. However, significant challenges remain, such as optimizing field-effective delivery methods and assessing potential off-target effects on non-target organisms. Continued innovation in RNAi technology is pivotal for developing sustainable and environmentally sound vector control strategies. This review synthesizes current research, highlighting the molecular insights, practical applications, and future directions for integrating RNAi into modern public health initiatives.
