Super-kdr mutation M918L and multiple cytochrome P450s associated with the resistance of Rhopalosiphum padi to pyrethroid.

Field-evolved resistance to pyrethroid insecticides has been found in R. padi. The M918L (super-kdr) mutation in the VGSC was documented for the first time in field samples obtained from an important wheat-growing area. The super-kdr mutation, as well as metabolic resistance mediated by P450 genes, was determined to contribute to the lambda-cyhalothrin resistance in R. padi. © 2020 Society of Chemical Industry.
