Abstract excerpt

The greenbug, Schizaphis graminum, is an aphid species that consists of races that can be separated based on morphology, life histories, cytogenetics, mitochondrial DNA RFLPs and virulence to plant cultivars. Variation in the greenbug rDNA multigene family was studied to determine the extent to w...
