Rowe, Carol Anne.

Phylogenetic position of Pterocommatinae and Cavariella , and implications for the origins of host alternation in aphids. - 40 p.

Major Professor: Carol D. von Dohlen.

Thesis (M.S.)--Utah State University, 2003.

The phylogenetic relationships of Cavariella and Pterocommatinae within Aphididae were reexamined using sequences of mitochondrial cytochrome oxidase II plus tRNA-Leucine plus partial cytochrome oxidase I (COII + trnL), and nuclear elongation factor-1alpha (EF1alpha). Independent and combined analyses were performed under unweighted parsimony and maximum likelihood criteria. Shimodaira-Hasegawa likelihood ratio tests were also employed to test for statistically significant differences between: (1) the tree topologies obtained from the analyses in this study; and (2) topologies supporting the traditional phylogenetic hypotheses based upon morphological data. These analyses recovered various relationships contradicting the current morphology-based phylogeny: (1) a highly supported sister relationship of Pterocommatinae to Cavariella; (2) paraphyly of Myzinae and Anuraphidinae, as well as paraphyly in some genera within Dactynotinae; and (3) support for the sister relationship of Pterocommatinae/ Cavariella/Liosomaphis to the remaining macrosiphines. There was also evidence within Aphididae for an evolutionary rapid radiation and multiple origins of host-alternation.
