Abstract
The aphid genus Uroleucon (Aphididae: Aphidinae: Macrosiphini) is a diverse group of about 230 species feeding mainly on Asteraceae as host plants and found globally in most temperate regions. However, the origins of the South American species are unknown, as are the relationships of these taxa to northern hemisphere Uroleucon species. This study seeks to establish the relationships between Uroleucon aphids native to South America and their North American and Eurasian counterparts using genetic data. We will use phylogenetic analysis of cytochrome c oxidase subunits 1 and 2 mitochondrial genes as well as the elongation factor 1α nuclear gene to reconstruct the relationships of all sampled species. We will use the phylogeny to statistically date the divergence of the South American Uroleucon from the northern species, and to hypothesize the intercontinental movements that may have founded the ancestors of the South American lineages.
