AB  - The dissipation of flonicamid in Honeysuckle and transfer pattern from 
      Honeysuckle to its tea infusion were investigated. Flonicamid was applied on 
      Honeysuckle crop at two dosages, 60 g of active gradient per hectare (g a.i. 
      hm(-2)) and 180 g a.i. hm(-2) (recommended and triple the recommended) in Fenqiu, 
      Henan Province in 2015 and 2016. Gas Chromatography-Electron Capture Detector 
      (GC-ECD) detection methods were developed for the analysis of flonicamid residues 
      in honeysuckles and its infusion. The recoveries in both honeysuckles and its 
      infusion ranged from 81.5 to 101.7% with relative standard deviations (RSDs) of 
      3.2-9.1%. The dissipations of flonicamid in Honeysuckle were found to follow the 
      first order kinetics with half-life ranging between 2.8 and 3.2 d. After 
      recommended dose pesticide application, contents of flonicamid residues were 
      lower than theoretical maximum residue limit (tMRL). Flonicamid residues can 
      easily transfer from Honeysuckle to its tea infusion and transfer rates of 
      flonicamid decrease with the brewing temperature reduction or the brewing times 
      increase. These results are helpful to establish maximum residue limit and 
      develop guidance on the appropriate and secure use of flonicamid in Honeysuckle.
