To investigate the presence of nitenpyram in kiwifruit, a field experiment was conducted in six kiwifruit producing regions in China. A modified quick, easy, cheap, effective, rugged and safe method (QuEChERS) method based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed for the determination of nitenpyram in kiwifruit. Quantitative detection was performed by LC-MS/MS in multiple reaction monitoring (MRM) mode under positive-ion electrospray ionisation. The proposed method is linear and accurate in the range of
