Smith, P. T., K. Krager, J. T. Cronin and S. Kambhampati. 2002. Mitochondrial DNA variation among host races of Eurosta solidaginis Fitch (Diptera: Tephritidae). Molecular Phylogenetics and Evolution 25: 372-376.


Eurosta solidaginis Fitch (Diptera: Tephritidae) induces galls on two species of goldenrod (Compositae) in the northern regions of the United States. Recent studies have demonstrated that E. solidaginis is comprised of two host races that differ in adult emergence times, mate preference, and host preference. Sequencing analysis was used to characterize two mitochondrial gene fragments: (1) NADH1 dehydrogenase (ND1: 539bp) and (2) cytochome oxidase II + tRNA-Lys + tRNA-Asp (CO2KD: 396bp) from sympatric host-associated populations of E. solidaginis in North Dakota. DNA sequence analysis indicated that two genetically distinct lineages exist among E. solidaginis from North Dakota that correlated with host plant association.
