“…In 2015, OLB entered Russia and was found in the Krasnodar city park [24]. Satellite images of the oak forests confirmed the OLB spread into the North-West Caucasus [43] and extended to the south of the European part of Russia [44][45][46][47]. In 2015, the first report of OLB in Romania was published.…”

This scientific paper examines the impact of climate change on the spread and survival of the invasive species Corythucha arcuata Say, 1832 (oak lace bug, or OLB) in Romania. The OLB is native to the Eastern USA and Canada, and in its native habitat, it coexists with minimal impact to the preferred host plant species Quercus. However, in Europe, the OLB in high density causes early defoliation, slowing tree growth. As Quercus spp. is a keystone species, the impact of the OLB on European forests is significant. This paper aims to address several gaps in knowledge about the OLB by presenting findings from a study conducted by the Lucian Blaga University of Sibiu (ULBS) in Romania. The study identified the species’ chronology of spread, ecology, ethology and biology of the species, in addition to foliage classification to determine the extent of attack. The study found a direct link between the temperature and the speed of the generational lifecycle. The findings support the thesis that climate change is enabling the healthy, rapid density growth of OLB, which is a danger to the Quercus spp. Further research is needed in the area of the thermal tolerance of the OLB, and the research conducted by the ULBS represents the first documented research into the thermal constant of the insect. The paper concludes that further research must be in the direction to understand how and where these insects survive during winter to find future management measures and identify chemical or biological methods as solutions to eradicate and stop the expansion of the invasion of the OLB, and the potential consequences for the Quercus sp.

This scientific paper examines the impact of climate change on the spread and survival of the invasive species Corythucha arcuata (Oak Lace Bug, or OLB) in Romania. The OLB is native to the Eastern USA and Canada, and in its native habitat, it coexists with minimal impact to the preferred host plant species Quercus.

As Quercus is a keystone species, the impact of the OLB on European forests is significant.

Aim. Study of the genetic variability of the pear lace bug Stephanitis pyri F. depending on geographical location and trophic specialization.Material and Methods. The object of the study was insect samples (n=60) from the natural population of the pear lace bug Stephanitis pyri F. (Tingidae: Heteroptera) in the Krasnodar Territory: in Krasnodar, Kropotkin and Novorossiysk. The collection of S. pyri bugs was carried out on model trees of domestic apple (Malus domestica Borkh) and sour cherry (Prunus cerasus L.). Molecular genetic analysis was carried out in several stages: sample preparation, DNA extraction, and diagnostics based on RAPD (random amplified polymorphic DNA)‐PCR (DNA amplification).Results. With the help of molecular genetic markers, the genetic variability of the pear lace bug in the Krasnodar Territory was studied. The indicators of genetic differentiation between geographic (Gst=0.209) and trophic (Gst=0.049–0.302) intrapopulation groups of S. pyri were calculated. The levels of variability were determined within geographic (79.1 %) and trophic groups (70.0–95.1 %), as well as between them – 20.9 % and 4.9–30 %, respectively. The influence of the food factor on the genetic diversity and differentiation of insect populations is shown through the example of the Kropotkin trophic group of bugs that prefer the sour cherry P. cerasus as the main food plant.Conclusion. A small effect of isolation by distance was noted, which was characterized by a weak dependence of geographical and genetic distances between the population groups of the pear lace bug. The influence of the nutritional factor on the genetic variability of phytophages populations has been established, as is confirmed by other researchers.
