Abstract: Thysanoptera (thrips) are tiny but highly damaging agricultural pests. They feed on multiple plant tissues with rasping-sucking mouthparts and transmit numerous plant viruses, causing severe economic losses. The long-term overuse of chemical pesticides has intensified resistance evolution, the control effect of natural enemy insects on pests has weakened, and increased risks of environmental contamination and pesticide residues, moreover resulting in threatening ecological security and food quality safety. Therefore, exploring novel insecticidal resources and developing green control technologies are urgently needed. Following the logic of microbial resource screening and application evaluation, RNA interference technology routes, integrated control strategies, and industrialization challenges, this review summarizes recent progress in microbial pesticides and RNA interference technology for thrips management. It further synthesizes these studies in terms of action mechanisms, field adaptability, delivery efficiency, resistance management, and commercialization feasibility. Microbial pesticides show advantages in resource availability and commercial maturity, whereas RNA interference technology exhibits strong potential in target specificity and environmental safety. Future research work should focus on efficient strain discovery, stable dsRNA delivery, combined formulation development, and risk assessment frameworks, and develop a comprehensive integrated system strategy that combines microbial pesticides, RNA interference technology, and protection of natural enemies to achieve green governance and control of pests. This will provide theoretical support and technical path product guarantees for the sustainable control of thrips.
