The first record and the beginning the spread of oak lace bug, Corythucha arcuata (Say, 1832) (Heteroptera: Tingidae), in Slovenia

Abstract

Here we report the discovery of Corythucha arcuata in Slovenia in autumn 2016. Egg shells and molts of oak lace bug were found on the fallen leaves of Quercus robur in an oak forest in the village of Zakot near Brežice in the southeastern part of Slovenia. C. arcuata most likely spread to Slovenia from Croatia, where it was previously reported from the park at Lužnica Castle near Zaprešić, 14 km from the find in Slovenia, or as a hitchhiker on rail traffic running along the northern edge of infested forest. Further spread of C. arcuata to Krakovo oak forest was detected in the beginning of July 2017.
