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.
Highlights
Invasions of adventitious pests are a great problem of our time caused by globalization processes leading to wide transport communication between continents, states and regions
The aim of this research was to study some issues of phenology, biological features, and divergence of C. ciliata species, which is widespread in the South of Russia on the basis of phytosanitary monitoring and analysis of the variability of the molecular genetic structure and genetic similarity of various geographical samples from the plane lace bug population in Krasnodar Krai
As a result of the studies, the biological and phenological features of the plane lace bug were studied in the central zone of Krasnodar Krai in 2018-2019
Summary
Invasions of adventitious pests are a great problem of our time caused by globalization processes leading to wide transport communication between continents, states and regions. The study of alien insect species becomes a matter of environmental and economic security of countries, because many of them cause huge damage to agriculture and forestry, destroy local ecosystems [1]. The plane lace bug (Corythucha ciliata Say) is a natural inhabitant of North America. The species spread to other European countries: Croatia, Slovenia (1972), South of France (1975), Hungary (1976) South Austria (1983), Switzerland (1983), the former Czechoslovak Republic (1986), Bulgaria (1986), Greece (1988) [4]. In 2002, an invasive pest was first detected in China, in the Hunan province, afterwards it spread to 11 provinces and concentrated along the Yangtze River basin [5]. In 2014 the bug colonies were found on plane trees in the Republic of South Africa (Cape Town) [6]
