The effect of sublethal doses of flupyradifurone on the life table and esterase enzyme of Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae)

Abstract

The aim of this study was to determine the effect of two different sublethal doses (LC10 and LC30) of flupyradifurone on the life table and esterase enzyme of Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae). The experiments were conducted in 2022 in Isparta University of Applied Sciences laboratory and climate rooms in 2022 as 1 control + 2 sublethal doses. For the life table, control, LC10 and LC30 doses were established as 30, 25 and 30 replications, respectively. Female and total lifespan of M. persicae adults exposed to LC10 concentrations of flupyradifurone were significantly shortened. Daily and total numbers of the offsprings decreased at both LC10 and LC30 concentrations. Furthermore, these negative effects on the aphid were revealed as a lower intrinsic rate of increase (r), net reproductive rate (R0), finite rate of increase (λ) and fecundity (F). Based on the obtained data, flupyradifurone seems to suppress the population growth of M. persicae. It was determined that esterase enzyme activity involved in pesticide detoxification did not change in populations exposed to two different sublethal doses of flupyradifurone and unexposed (control). It is thought that this study facilitates the understanding of the lethal and sublethal effects of flupyradifurone on aphid performance.
