Molecular genetic analysis and phenology of the plane lace bug Corythucha ciliata Say (Hemiptera: Tingidae) in different parts of Krasnodar Krai

Abstract

The article presents the results of studying the phenology and dynamics of the number of plane lace bug Corythucha ciliata Say. RAPD analysis of geographic populations of plane lace bug from various parts of Krasnodar Krai revealed a high level of DNA polymorphism, genetic diversity, genetic similarity and the absence of significant differences between the samples for these indicators. It shows that the majority of the genetic variation (90.2 %) is intrapopulation, while the interpopulation variation accounts for 9.8 % of the total. A significant drift of genes was revealed between the populations of C. ciliata (Nm = 4.56) and a high degree of genetic similarity between them at the intraspecific level. The analyzed insect samples are concluded to be subpopulations of one plane lace bug population.
