“…WCR has been introduced to the EU from North America (Miller et al, 2005), where it is native and widespread. It was first detected near Belgrade (Serbia) in 1992, but has since spread across the continent (Hummel, 2003;Kiss et al, 2005a;Boriani et al, 2006;Ciosi et al, 2008;Gray et al, 2009;Meinke et al, 2009), resulting in well-established populations in approximately 19 European countries (EC, 2012). 5 It is expected that this invasive pest species will expand further in the EU (Hemerik et al, 2004;Moeser and Vidal, 2005;Ciosi et al, 2011;Aragón and Lobo, 2012).…”
