Abstract：ObjectiveTodeterminetheresiduesof6neonicotioidsinWolfberyandevaluatetheriskofchronicdietaryintake basedontheresidues.Methods Theresidualamountofneonicotinoids in12batchesofWlfberywasdeterminedbyQuEChERS-Ultra-high PerformanceLiquid Chromatography-Tandem Mass （UPLC-MS/MS），and thepesticide transferrate was investigated by fourextractionmethods.Thedietaryriskwasevaluatedaccordingtomaximumresiduelimit（MRL）andchronicdietaryintakeriskformula.ResultsNeonicotinoidpesticidesweredetectedinallthe12batchesof Wolfbery，includingdinotefuran，thiamethoxam， clothianidin，imidacloprid，acetamiprid and thiacloprid. The detection rateswere 8.3% ， 83.3% ， 75.0% ， 100% ， 100% and （20号 16.7% ，respectively. The transfer rates were 43.0% ， 97.0% ，62. 5% ， 42.8% ， 81.9% and 4.6% ，respectively. All neonicotinoid pesticide residues did not exceed MRL value，and %ADI value was less than 1% .Conclusion Although the detection rate of 6 neonicotinoids in 12 batches of Wolfberry was higher，the dietary risk was lower.
