Aphids represent pests that attack countless crops and are able to stay on weeds, being these excellent hosts. Its importance lies in being one of the main vectors of virus and few give importance to study their taxonomy. In the state of Coahuila there in no information about the diversity of aphids, despite the importance they represent to the state's agricultural crops. In the present study were made weekly collections for a year from August 2009 to August 2010, in the southeast of Coahuila on weeds and crops in the region. The material was collected from the above ground parts, stems, roots, f lowers depending of the location. The material was processed in the taxonomy laboratory from UAAAN for further taxonomic analysis. Were determined 21 genera and 27 species, the dominant species was Macrosiphium euphorbiae in a wide range of crop and weed hosts, followed by Aphis spiraecola; both of agricultural importance for transmitting viruses to crops. These species were collected from 22 species of host plants. The family Asteraceae represented the main host, a total of 27 species of aphids, 11 were collected from hosts of this family. Following in order of importance the families Poaceae, Apiaceae, Cruciferae, Roseaceae, Polygonaceae, Solanaceae being these the most representative.
