Temporal Variation in Genetic Composition of Migratory Helicoverpa Zea in Peripheral Populations.

ABSTRACT: Migrant populations of Helicoverpa zea (Boddie) captured during 2002, 2005, 2016, and 2018 from Landisville and Rock Springs in Pennsylvania, USA were genotyped using 85 single nucleotide polymorphism (SNP) markers. Samples (n = 702) genotyped were divided into 16 putative populations based on collection time and site. Fixation indices (F-statistics), analysis of molecular variance, and discriminant analysis of principal components were used to examine within and among population genetic variation. The observed and expected heterozygosity in putative populations ranged from 0.317-0.418 and 0.320-0.359, respectively. Broad range of F_ST (0.0-0.2742) and F_IS (0.0-0.2330) values indicated different genotype frequencies between and within the po
