The specificity of parasitic interaction depends on the adaptations of both the host and the parasite. Over time, these interactions evolve and change as a result of an “arms race” between host and parasite, and the resulting species-specific adaptations may be maintained, perpetuating these interactions across speciation events. With speciation and species sorting over time, complex systems of interactions evolve. Here, we elucidate some of these interactions using the aphids (Hemiptera: Aphididae) of Churchill as a model system. We analyzed these interactions by testing for two patterns in host-specificity: monophagy and phylogenetic clustering. We defined monophagy as one species feeding upon a single host plant species, an association which is driven by arms races in morphology, chemical resistance/tolerance, and camouflage; this pattern was observed in 7 of 22 aphid species. Secondly, we observed three separate cases where groups of closely related aphid species fed upon individual plant species ... : Aphid dataAccession, collection and sequence data for the aphids associated with this publication.

Each plant species targeted in our study had three DNA barcode gene regions (ITS2, rbcLa, and matK; Hollingsworth et al. 2009) represented with the exception of Larix laricina, which lacked a matK sequence. For each plant species, and each gene region, the highest quality sequence (longest sequence containing the lowest number of ambiguous bases) was selected. The three genes were concatenated using FaBox (Villesen 2007), ...
