New records of non-native Coleoptera in Italy

Abstract

In the last decades, climate change and globalisation have been exacerbating the introduction of non-native beetles worldwide. Due toits peculiar territory, climate and geographical position in the middle of the Mediterranean Basin, Italy is one of the European countries with the highest number of intercepted, adventive and established non-native beetles, some of which are invasive. In this perspective, producing new faunistic records and continuously updating reliable and easily accessible distributional data is a fundamental step in investigating and potentially preventing further species introduction. The aim of this contribution is to report and discuss new faunistic records of non-native Coleoptera in Italy. For some species, new records enlarge the previously-known distribution (e.g. the ambrosia beetles Anisandrus maiche (Kurentzov, 1941) and Cnestus mutilatus (Blandford, 1894) or the click beetle Monocrepidius posticus (Eschscholtz, 1829)), while for others (e.g. the scarab beetle Archophileurus spinosus Dechambre, 2006), data confirm their establishment and highlight a possible expansion phase. The false powderpost beetles Ptilineurus marmoratus (Reitter, 1877) and the longhorn beetle Xylotrechus chinensis (Chevrolat, 1852) are two new additions to the Italian fauna, while the establishment of the monotomid beetle Monotoma americana Aubé 1837 is confirmed.

New evidence on the spread in Catalonia of the invasive longhorn beetle, Xylotrechus chinensis, and the efficacy of abamectin control

“…Soon afterwards it was reported as established in Greece, southern France and the region of Valencia in Spain (see Sarto i Monteys et al 2021 for comprehensive details of sites and literature). On June 10, 2023 it was found for the first time in Italy, at Prevalle, as well as at Muscoline (June 23) and Roè Volciano (July 2), all in the province of Brescia (Lombardy) (Ruzzier et al 2023). Later, during July 2023, the Plant Health Service of Lombardy conducted visual inspections on mulberry trees in nine municipalities of this province: Salò, Roè Volciano, Gavardo, Prevalle, Muscoline, Puegnago sul Garda, San Felice del Benaco, Manerba del Garda and Calvagese della Riviera, observing signs of infestation in all of them but the last two.…”

Simultaneous detections of Olenecamptus bilobus (Fabricius, 1801) (Cerambycidae, Dorcaschematini) in Europe

“…Europe, given its importance and central role in the world economy for at least the past three centuries, has a long history of non-native cerambycidae introductions (e.g. Cocquempot and Lindelöw (2010) , Lupi et al (2013) , Rassati et al (2016) , Maestre del Peral and Bahillo de la Puebla (2017) , Binazzi et al (2019) , Arias and Torralba-Burrial (2020) , Ruzzier et al (2020) , Ruzzier et al (2023) ). In recent decades, this trend of introduction has been shifting mainly towards species of East Palearctic and Oriental origin with some capable of developing adventitious populations on the European territory (e.g.…”
