Abstract
A comparison between QuEChERS and other pesticide extraction procedures for honey and honey bee matrices is discussed. Honey bee matrix was extracted by solvent based procedure whereas solid phase extraction was the protocol for the honey matrix. The citrate buffered QuEChERS method was used for both matrices. The methods were evaluated regarding cost (equipment and reagents), time, accuracy, precision, sensitivity and versatility. The results proved that the QuEChERS protocol was the most efficient method for the extraction of the selected pesticides in both matrices. •QuEChERS is the most economical and less time-consuming procedure.•SPE and solvent-based extraction procedures show equivalent recoveries to QuEChERS.•QuEChERS can be used to extract pesticide residues from both matrices.

6) Dissolve the extract obtained from the honey bee samples in acetone, up to 2 mL, for GC analysis
The LOQs were determined in pure solvent and in spiked honey and honey bees samples
Summary
Enrique Simób , Yolanda Picóa a Environmental and Food Safety Research Group (SAMA-UV), Research Center on Desertification (CIDE, UVCSIC-GV), Faculty of Pharmacy, University of Valencia, Av. QuEChERS can be used to extract pesticide residues from both matrices. QuEChERS approach for the extraction of pesticide residues in honey and honey bee matrices [8_TD$IF][1,2,3]. 1) Weigh 5 g of honey or honey bees into 50 mL centrifuge tubes and add 7.5 mL of water, 10 mL of acetonitrile, 6 g of MgSO4 and 1 g of NaCl. Homogenize the mixture immediately and centrifuge for 5 min at 300 rpm.
