Xylosandrus compactus, a new forest pest in Italy

Abstract

The black twig borer Xylosandrus compactus, an ambrosia beetle native to Asia, was recorded for the first time in Europe in 2011 in central Italy. This paper reports the progressive dispersal of this invasive species in many Italian regions (Campania 2011, Tuscany and Liguria 2012, Lombardy 2015, Lazio and Sicily 2016, Emilia Romagna 2018, Veneto 2019) and other European countries (France 2015, Spain and Greece 2019). The main features of the biology and ecology are reported, and the infestation symptoms and the produced damages are descripted, as well. An updated list of the potential host-plants is also provided. Finally, protocols for the pest control are suggested.
