Abstract: This study analyzes the characteristics of registered and valid insecticides for red imported fire ant（Solenopsis invicta）control in China, aiming to provide a theoretical basis for scientific prevention and control, insecticide development, and optimization of registration management. By retrieving all registered insecticides targeting red imported fire ants from the China Pesticide Information Network, an analysis was conducted on their temporal distribution, formulation types, active ingredients, toxicity classifications, active ingredients and application methods. Key findings reveal that as of October 2025, a total of 91 registered insecticides for red imported fire ant control were retrieved. The number of registered insecticides increased significantly since 2008, while the validity period was shortened from 20 years to 5 years. The formulation composition of these insecticides is predominantly bait（74.73%）and powder（17.58%）. In terms of active ingredients, indoxacarb（36.89%）and hydramethylnon（15.53%）are dominant, highlighting issues of homogeneity and a notable shortage of bio-pesticide applications. The formulation structure of these insecticides is characterized by simplification（approximately 80%）. Furthermore, inconsistencies and oversimplification were observed in the descriptions of application methods in the registration documents. Based on the findings, recommendations include enhancing the scientific combination of bait and contact insecticides, accelerating the development of waterproof baits and diversified compound products, and promoting the research and application of bio-pesticides. Additionally, establishing a pre-review mechanism at the registration management level, standardizing application descriptions, and implementing dynamic efficacy evaluations are suggested to comprehensively improve the overall effectiveness of red imported fire ant control.
