Evidence for gene flow and local clonal selection in field populations of the grain aphid (Sitobion avenae) in Britain revealed using microsatellites
Article Abstract:
The genetic analysis of Sitobian avenae samples collected from a field in Britain at small spatial scales is described. It is found that field samples display a high level of genotypic heterogeneity (variable clone composition) due to clonal selection and the suction trap genotypes sample are found slightly different from the field samples, indicative of the inclusion of genotypes from plant hosts other than winter wheat or genotype-biased emigration from the field.

Genetic structure and clonal diversity of an introduced pest in Chile, the cereal aphid Sitobion avenae
Article Abstract:
The genetic diversity of Sitobion avenae in Chile with microsatellites, considering the impact of reproductive mode, interaction with host plants and introduction on aphid population structure is examined. The identity of the genotypes found in Chile is compared with that of clones that were monitored in earlier surveys of Sitobion avenae populations in Western Europe.
