First report of Halyomorpha halys in Croatia
In 2017, Halyomorpha halys (Hemiptera: Pentatomidae – formerly EPPO Alert List) was observed for the first time in Croatia. The first specimen (1 female) was incidentally found on 2017-01-15 in a flat in the city of Rijeka (major seaport in Croatia). In the same flat, a male specimen was found on 2017-02-25. In May 2017, more H. halys specimens (1 female, 3 males) were collected using a sweep net on Ailanthus altissima trees growing near the building concerned in Rijeka. A genetic analysis has shown that the Croatian specimens belonged to a haplotype that is found within nearby Italian and Hungarian populations of H. halys.
