Генетическая вариабельность аборигенных и инвазивных видов тлей родов Macrosiphum Pass. и Brachycaudus Van der Goot

Abstract

The study of genetic structure of populations of aphid of genera Macrosiphum and Brachycaudus in Belarus and Armenia was carried out. Methods for analysis of non-coding (STR) and highly conserved (COI) DNA were used to compare the level of genetic variability of invasive and aborigine populations. It was shown that the genetic variability within populations of M. rosae and M. knautiae was not high, despite the significant geographical remoteness. The samples from Belarus were more variable than samples that samples collected in Armenia. The invasive populations of B. divaricatae from Belarus had a lower level of genetic variability in comparison with the aborigine forms from Armenia.
