Aryl hydrocarbon receptor (AhR) enhances insect resistance to insecticides by regulating the detoxification network. Our previous studies have confirmed that overexpressions of cytochrome P450 monooxygenases (P450s) and glutathione S-transferases (GSTs) are involved in lambda-cyhalothrin resistance in Cydia pomonella. Here, we report that CpAhR regulates the expression of GST and P450 genes, thus conferring resistance. Expression patterns indicated that the expression of CpAhR was highly induced by lambda-cyhalothrin exposure and upregulated in a lambda-cyhalothrin-resistant population. RNA interference (RNAi) of CpAhR decreases the expression of key resistance-related genes (CpGSTe3, CpCYP9A121, and CpCYP9A122) and the activity of the GST enzyme, reducing the tolerance to lambda-cyhalothrin. Furthermore, β-naphthoflavone, a novel agonist of AhR, was first proven to be effective in increasing CpAhR expression and larval tolerance to lambda-cyhalothrin. These results demonstrate that CpAhR regulates the expression of key detoxifying genes and GST activity, resulting in the development of resistance to lambda-cyhalothrin in C. pomonella.

“…C. pomonella is a destructive pest of pome fruits worldwide that causes a great loss of both quality and yield, and the use of chemical insecticides has been considered the most effective and direct control measure [3,34,35]. It has been demonstrated that prolonged exposure to insecticides inevitably leads to the problem of an increase in insecticide resistance, which causes almost all pests will be uncontrollable again, including C. pomonella [7,36,37].…”

Transcription factor aryl hydrocarbon receptor (AhR) can enhance insect resistance to insecticides by regulating the detoxification metabolic network. Our previous studies have confirmed that overexpression of cytochrome P450 monooxygenases (P450s) and glutathione S-transferases (GSTs) are both involved in lambda-cyhalothrin resistance in Cydia pomonella. In this study, we report that AhR regulates GSTs thus conferring lambda-cyhalothrin resistance in C. pomonella. Spatiotemporal expression patterns indicated that AhR gene of C. pomonella (CpAhR) was highly expressed in the Malpighian tubules of larvae. Moreover, the expression of CpAhR was induced by lambda-cyhalothrin exposure and was up-regulated in a lambda-cyhalothrin-resistant population. RNA interference (RNAi) of the expression of CpAhR could effectively decrease the relative expression level of CpGSTe3 and enzyme activity of GSTs, but not P450s, further reducing the tolerance of larvae to lambda-cyhalothrin. Furthermore, β-naphthoflavone (BNF), a novel agonist of AhR, can effectively increase the expression of CpAhR and the activity of the GSTs enzyme, resulting in the enhancement of larvae tolerance to lambda-cyhalothrin. These results demonstrate that lambda-cyhalothrin exposure can effectively activate the expression of CpAhR and increase GSTs enzyme thus leading to the development of resistance to lambda-cyhalothrin, which enriches the theory of insecticide resistance regulation in C. pomonella.
