Weevils and Bark Beetles (Coleoptera, Curculionoidea). Chapter 8.2

Abstract

We record 201 alien curculionoids established in Europe, of which 72 originate from outside Europe. Aliens to Europe belong to fi ve families, but four-fi fths of them are from the Curculionidae. Many families and subfamilies, including some species-rich ones, have few representatives among alien curculionoids, whereas some others are over-represented; these latter, Dryophthoridae, Cossoninae and specially Scolytinae, all contain many xylophagous species. Th e number of new records of alien species increases continuously, with an acceleration during the last decades. Aliens to Europe originate from all parts of the world, but mainly Asia; few alien curculionoids originate from Africa. Italy and France host the largest number of alien to Europe. Th e number of aliens per country decreases eastwards, but is mainly correlated with importations frequency and, secondarily, with climate. All alien curculionoids have been introduced accidentally via international shipping. Wood and seed borers are specially liable to human-mediated dispersal due to their protected habitat. Alien curculionoids mainly attack stems, and half of them are xylophagous. Th e majority of alien curculionoids live in human-modifi ed habitats, but many species live in forests and other natural or semi-natural habitats. Several species are pests, among which grain feeders as Sitophilus spp. are the most damaging.

Distribution of Tomicus destruens (Coleoptera: Scolytinae) mitochondrial lineages: phylogeographic insights and niche modelling

“…In this study, we consider the entire Mediterranean Basin, comprising the areal of T. destruens, excluding the Macaronesian region, where it is considered to be an alien species (Sauvard et al 2010). We have considered a total of 45 sites where T. destruens was present, in accordance with Horn et al (2006) and our samples (Fig.…”

Temporal and interspecific variation in rates of spread for insect species invading Europe during the last 200 years

“…The predatory Harlequin ladybeetle, Harmonia axyridis, has invaded most of Europe since its discovery in 1991 in Belgium (Brown et al 2011 ). Several species associated with palm trees, such as the palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae) and the palm moth, Paysandisia archon (Lepidoptera: Castniidae), have also expanded their ranges rapidly across the Mediterranean Basin since the early 2000s (Sauvard et al 2010 ;Lopez-Vaamonde et al 2010 ), as did the gall makers, Ophelimus maskelli and Leptocybe invasa (Hymenoptera: Eulophidae) , and the psyllids, Acizzia jamatonica and Glycaspis brimblecombei (Hemiptera: Psyllidae; Mifsud et al 2010 ;Bella and Rapisarda 2013 ) associated with Eucalyptus. In contrast, for unknown reasons some species have not spread at all since their establishment, despite apparently favourable conditions.…”

“…In contrast, for unknown reasons some species have not spread at all since their establishment, despite apparently favourable conditions. An example is the poplar-feeding ambrosia beetle, Megaplatypus mutatus (Coleoptera: Curculionidae) that was reported in 2000 in southern Italy (Sauvard et al 2010 ).…”

A new subgenus of the weevil genus Otiorhynchus Germar, 1822 (Coleoptera: Curculionidae: Entiminae) for a new species from Mediterranean Turkey associated with the carob tree, Ceratonia siliqua L. (Fabaceae)

“…Astrin et al (2012) record C. siliqua as a host for three species of Cryptorhynchinae (Curculionidae): Echinodera incognita (Hoffmann, 1956), Echinodera ibleiensis Stüben, 2003, andKyklioacalles maroccensis (Stüben, 2001). Mifsud & Colonnelli (2010) (Sauvard et al 2010). Friedman & Freiberg (2007) report findings of two apionids on C. siliqua in Israel, Kalcapion semivittatum (Gyllenhal, 1833) and Taeniapion rufescens (Gyllenhal, 1833), but both develop on other plants and are definitely occasional feeders on or visitors of the carob tree.…”
