Soybean aphid,<i> Aphis glycines</i>, field abundance from field collection and corresponding vgsc-h1 genotypes

Data collected for soybean aphid, Aphis glycines, on soybean, Glycine max, in field efficacy trials conducted at the Iowa State University Northwest Research Farm, Sutherland, IA in 2023. Comprised of field aphid abundance (counts) from 10 sampled plants before and after insecticidal treatments, and corresponding genotypes of aphids at the voltage-gated sodium channel subunit h1 gene (vgsc-h1) encoding amino acid changes from a methionine at the vgsc-h1 protein position 918 to either isoleucine (M918I) or leucine (M918L), a leucine to methionine substitution at the 925 position (L925M), and leucine to phenylalanine change at position 1014 (L1014F).
