Reduced neuronal sensitivity and susceptibility of the fall armyworm, Spodoptera frugiperda, to pyrethroids in the absence of known knockdown mutations.

Pesticide biochemistry and physiology - 1 Oct 2020

Abstract excerpt

Neurophysiological recordings were employed to quantify neuronal sensitivity to neurotoxic insecticides and assessed toxicity across field and laboratory fall armyworm (FAW) populations. Topical toxicity resistance ratios (RR) in field-collected FAW was 767-fold compared to laboratory strains and, importantly, a 1750-fold reduction in potency was observed for λ-cyhalothrin in neurophysiological assays.
