Abstract

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.

Highlights

Myzus persicae (Sulzer) (Hemiptera: Aphididae), known as green peach aphid, is a pest that causes significant crop loss in vegetables, tobacco, fruit and ornamental plants worldwide
The highest resistance rate for acetamiprid was determined in the K1 population with 7.35 fold and the lowest resistance rate was found in the E2 population with 2.72 fold
Among the M. persicae populations, a lower level of resistance to acetamiprid was detected in E1 and E2 populations

Summary

Introduction

Myzus persicae (Sulzer) (Hemiptera: Aphididae), known as green peach aphid, is a pest that causes significant crop loss in vegetables, tobacco, fruit and ornamental plants worldwide. This pest, harms the plant by absorbing its sap and releases a sweet-sticky substance during feeding. M. persicae resists environmental pressures as a result of the high genetic diversity achieved through sexual reproduction. It is active throughout the year especially in areas with homogeneous conditions such as greenhouse production areas and can cause great damage by increasing the population density with parthenogenetic reproduction. M. persicae is one of the most important aphid pests in the world because of its host diversity, mechanism of damage, life cycle, as well as its ability to spread rapidly, transmit viral diseases and develop resistance to insecticides (Pavela 2018)
