In this study, the development of imidacloprid and acetamiprid resistance in Myzus persicae populations and the relationship between neonicotinoid resistance and esterase enzyme were investigated in seven Myzus persicae populations which is collected from greenhouse pepper production areas in 2018. In order to determine the resistance ratios of aphid populations against the insecticides, 1 control and 6 doses were used. Each insecticide dose was used in 3 replicates and 25 adult female individuals were used in each replication. For imidacloprid, the highest and the lowest resistance ratios were found to be 6.88 and 3.19-fold, in K-4 and D populations, respectively. For acetamiprid, the highest and the lowest resistance ratios were found to be 7.35 and 2.72-fold, in K-1 and E-2 populations, respectively. Also, highest and lowest esterase activities were found to be 2.60 and 1.75 mOD min-1 mg-1 in K-4 and E-2 populations, respectively. According to the results of this study, imidacloprid and acetamiprid resistance determined in some Myzus persicae populations may be related to esterase enzyme. However, detailed studies are required to establish a clear relationship between resistance and enzyme.
