First records of the brown marmorated stink bug Halyomorpha halys (Stål, 1855) (Heteroptera, Pentatomidae) in Russia, Abkhazia, and Georgia

Abstract

The brown marmorated stink bug Halyomorpha halys (Stål, 1855) is recorded for the first time from Russia (Khosta and Adler districts of the city of Sochi), Abkhazia (Pitsunda), and Georgia (Khobi Municipality). Outbreaks of H. halys populations were detected in all of these regions in October 2016. More than a hundred specimens congregated for overwintering were collected in Sochi during two days. According to the personal communications of the local people, the species appeared in Sochi not later than in 2013, and in Georgia not later than in 2015. It must have been brought to Sochi from Europe (from Italy) with planting material of ornamental plants for landscaping the XXII Olympic Winter Games. Thereafter it spread to Abkhazia and Georgia. Additional steps to identification of H. halys are provided for the keys to the true bugs of the European part of the former USSR (Kerzhner and Jaczewski, 1964).
