Abstract

Intra- and interpopulation variation of occurrence of elytral ridge (neutral morphological character with the known genetic determination) in some populations of Harmonia axyridis from the Russian part of the species area was studied for the first time. Comparative analysis of the frequencies of the recessive allele r of a corresponding gene and the frequencies of recessive homozygotes in 32 samples from 16 localities has shown the lack of temporal and microgeographic variations of this trait. The character of its geographic variation con-firms the hypothesis advanced earlier on the basis of analysis of elytral pattern variation about the existence of two subspecies of H. axyridis and suggests the existence of a zone of secondary hybridization between them in the central part of the area.
