Abstract： China is the world's largest vegetable producer，but frequent pest outbreaks severely constrain the sustainable development of this industry. Over-reliance on chemical pesticides has led to issues such as pesticide resistance，environmental pollution，and food safety concerns， driving an urgent need for green pest prevention and control technologies. Biological control， as a core strategy， has achieved significant progress. However， traditional methods employing natural enemies， entomopathogens， and biogenic pesticides still face challnges in field application regarding efficacy stability，cost-effectiveness，and compatibility with modern agriculture. Against this background，RNA interference（RNAi） technology，characterized by its high target specificity，novel mode of action，and designability，offers a new direction for precision pest management. This paper systematically reviews the recent research progress on major biological control methods for vegetable pests in China，analyzing the advantages and limitations of these techniques，and places particular emphasis on elucidating the unique potential and unresolved challenges associated with RNAi technology. It highlights that the organic integration of RNAi technology with traditional biological control approaches （such as the conservation and utilization of natural enemies，and enhancement of microbial agents） to develop synergistic and integrated strategies represents a key direction for achieving sustainable integrated pest management for vegetable pests. The aim is to provide a scientific reference for the development of ficient，environmentally friendly，and sustainable new systems for vegetable pest control.
