The fall armyworm, Spodoptera frugiperda, is a major pest native to the Americas that has recently invaded the Old World. A whole‐genome sequencing (WGS) approach was used to identify mutations associated with resistance to insecticides and Bt proteins in 150 individuals of S. frugiperda collected from China, Malawi, Uganda and Brazil. This approach revealed three amino acid substitutions (A201S, G227A and F290V) of the acetylcholinesterase‐1 (ace‐1) in the four geographical populations of S. frugiperda, which are known to be associated with organophosphate resistance. A novel Cry1F resistance allele in the ABCC2 gene was identified from the Brazilian population but absent in the invasive populations (see pages 627‐638). Photo provided by Prof. Run‐Zhi Zhang.
