This study focuses on the development and validation of a detection method for indoxacarb residues in three major vegetable crops, Chinese cabbage, cabbage, and tomato, which are widely cultivated worldwide. The method was rigorously validated through field trials and dietary risk assessment. A strong linear response was observed for indoxacarb at the concentrations of 0.0005 - 0.25 mg/L, with a limit of quantitation of 0.01 mg/kg. The half-life of indoxacarb ranged from 4.61 to 6.89 days in Chinese cabbage, 3.06 to 6.21 days in cabbage, and 2.28 to 3.46 days in tomato. The terminal residues were
