Abstract: In response to the challenges of growing insecticide resistance in piercing-sucking pests and the limitations of traditional chemical control methods, the research and application status of RNA interference (RNAi) technology in the green management of piercing-sucking pests was systematically reviewed. First, the mechanism of RNAi and its technical adaptability to the feeding behavior of piercing-sucking pests were elaborated. Next, key target genes validated in major pest groups, such as aphids, whiteflies, and planthoppers, as well as their interference effects, were summarized. The core bottlenecks hindering the industrialization of this technology were then analyzed, including issues such as dsRNA delivery efficiency, potential pest resistance, production costs, and environmental safety, along with corresponding optimization strategies. Finally, the application prospects of RNA-based pesticides and RNAi transgenic crops in future agricultural green pest management systems were discussed.

Key words: RNA interference, piercing-sucking pests, target gene(s), pest control, RNA-based pesticides
