Characterization of field-evolved resistance to pyridalyl in a near-isogenic line of diamondback moth, Plutella xylostella.

Considering that no relevant effects of synergists or oxidative metabolism were observed in NIL-PY, and that pyridalyl resistance results in significant fitness costs compared with IVF-S, further research will be conducted on the mechanism of target-site resistance. © 2020 Society of Chemical Industry.
