Abstract: Cyantraniliprole is one of the novel anthranilic diamide insecticides designed to target at the insect ryanodine receptor and has been used widespread in many vegetables especially melon. To ensure that only permitted levels of cyantraniliprole are consumed, the high selective and sensitive determination method is required. In this work, the combination of QuECHERs with HPLC-UV is proposed for the determination of Cyantraniliprole in melon. The insecticide was spiked into the melon samples prior to analysis, extracted by using QuEChERS, and determined by HPLC/ UV. The important parameters that affect the QuEChERs efficiency were investigated. NaCl was the best partitioning salt with the highest recovery ( 129. 77- 140.89 percent, RSD 4.51 percent) while Florisil (60-100 mesh) was the sorbent, which provided chromatograms with less interference and the mean recoveries obtained were within 1 29. 19-111. 66 percent (RSD 7. 10 percent). Under the optimized conditions, the proposed extraction method provided higher sensitivity compared to the traditional solvent extraction method. The LOD and LOQ for Cyantraniliprole were determined to be 0.1374 and 0.4580 ppm respectively. Moreover, the matrix effect was evaluated and the matrix-matched calibration method was applied.
