Última Genetic analysis of greenbug populations of Schizaphis graminum (Hemiptera: Aphididae) from Argentina and Chile based on enzyme variability Rev. Soc. Entomol. Argent. Saldúa,Luciana; Tacaliti,María S.; Tocho,Erica; Dixon,Anthony F. G.; Castro,Ana M.. Twenty-nine Schizaphis graminum (Rondani) populations and sixty clones collected from very contrasting regions of Argentina and Chile were investigated electrophoretically. A high degree of enzymatic polymorphism was found. The enzymatic structure was described for the esterase system, finding nine different loci. Latitudinal stratification was determined and populations were associated into three groups, according to the latitude they were collected from. The 90% of loci resulted polymorphic in the first group and 100% of loci were polymorphic in the rest. Observed heterozygosity was lower than expected. No group had fixed alleles according to Fsr values; group one had a slight heterozygous excess, while the other groups showed slight positive Fsr values,...
