An insecticide resistance test was conducted on western flower thrips (Frankliniella occidentalis) populations collected in greenhouse pepper cultivation fields in 12 regions of Korea to 10 different insecticides belonging to 8 chemical classes (Acrinathrin 5.7% SC, Acetamiprid 5% SL, Dinotefuran 10% SL, Spinetoram 5% WG), Abamectin 1.8% EC, Emamectin benzoate 2.15% EC, Chlorfenapyr 5% EC, Cyclaniliprole 4.5% EC, Fluxametamide 9% EC, Flometoquin 10% SC). A susceptible population cultured in laboratory was also included in the study to enable comparison of resistance, and insecticide responses based on resistance ratios. The resistance ratio differed according to region and insecticides. Acrinathrin showed high resistance rates in all regions. On the other hand, Fluxametamide, and Flometoquin showed low resistance ratios in most local populations.
