THE FIRST RECORD AND THE BEGINNING THE SPREAD OF OAK LACE BUG, Corythucha arcuata (Say, 1832) (HETEROPTERA: TINGIDAE), IN SLOVENIA PRVI NALAZ I POČETAK ŠIRENJA HRASTOVE MREŽASTE STJENICE, Corythucha arcuata (Say, 1832) (HETEROPTERA: TIN-GIDAE), U SLOVENIJI Maja JURC, Dušan JURC Summary 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. KEY WORDS: invasive species, alien species, pedunculate oak, Quercus robur, Slovenia Introduction Uvod Corythucha arcuata (Say, 1832) (Heteroptera: Tingidae) originates from North America and has a wide geographical range in the USA and Canada (Drake and Ruhoff, 1965; Rabitsch, 2008). The first incidence of the pest in Europe was recorded in Italy in May 2000 in one of the parks near Milan. It is known to be widely distributed throughout northern Italy, in the Lombardy and Piedmont regions (Bernardinelli and Zandigiacomo, 2000). It was found in southern Switzerland in 2002 (Forster et al., 2005) and in Turkey in 2003 (Mutun, 2003). Within just five years, the species spread to a large part of Turkey, including nine provinces (Mutun et al., 2009). In 2012 its presence was confirmed in a few localities close to transport routes or within towns in Bulgaria (Dobreva et al., 2013) and in 2013 in Hungary, where it was reported in a very small and localized population (Csóka et al., 2013). In 2013 C. arcuata was found in lowland stands of Quercus robur L. in eastern Croatia (Hrašovec et al., 2013) and in Serbia, in the oak forests of Srem in Vojvodina (Pap et al., 2015). The main hosts of oak lace bug are oaks belonging to the white oak group. A more detailed list of host plants is reported by Drake and Ruhoff (1965), Osborn and Drake (1917), Drew and Arnold (1997) and Dobreva et al. (2013), and includes Quercus muehlenbergii Engelm., Q. alba L., Q. macrocarpa Michx., Q. prinoides Willd., and Q. prinus L., Q. rubra L. as well as the leaves of the following genera: Castanea, Acer, Pyrus, Malus and Rosa. In Europe the hosts of C. arcuata are Quercus petraea (Matt.) Liebl, Q. robur L., Q. pubescens Willd., Q. cerris L., Q. rubra L., Rubus idaeus L., Castanea sativa Mill. and Rosa canina L.
