摘要

In the third paper devoted to the complex of aphid species closely related to Dysaphis devecta (Walker), an attempt of the phylogenetic analysis of the complex on the basis of all the available data was made. This complex may have originated from a small-sized specialized species with the entire life cycle occurring on Mains. Further development occurred in two ways: intensification of specialization to woody plants and appearance of forms alternating woody and herbaceous plants in their development.Subsequent evolution of the complex included an adaptation to new herbaceous host plants and intensified specialization to them. The process of adaptation to a new host was modeled in Shaposhnikov's experiment. In this experiment, a new form, approaching the species rank, was obtained.
