The RAPD‐PCR technique was used to determine genetic distances among different taxa of aphids. Seven primers were selected from 20 primers and used for cluster analysis based on the data of Nei's genetic distance (D). The results showed that the genetic distances between families, subfamilies, genera, species and populations (within species) are 0.5663 ± 0.0689, 0.4586 ± 0.02142, 0.3816 ± 0.0375, 0.2975 ± 0.0627 and 0.0433 ± 0.0222, respectively. The results may be helpful in the study of aphid's population differentiation and identification of aphids, especially for closely related species at DNA level.
