A simply and rapid method was established for determining acetamiprid residues in fruits through the experiment by gas chromatography. Sample were extracted, cleaned up, derivatived and subjected to gas chromatography with ECD detection. The lowest detectable concentration in fruits samples were 0.005 mg/kg. Sample recoveries ranged from 74.60 to 99.70%. The coefficients of variation from 3.12 to 7.76%.
