Scolytinae (Coleoptera: Curculionidae) are one of the most successful groups of invasive species. They are generally moved among continents transported within live plants, timber and wood-packaging materials. The damages caused by these insects, of economic and ecological relevance, can be caused both by the direct action of burrowing within host p...

The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) on non‐coniferous hosts, which total 6495 known species. Most species attack apparently healthy, weakened or dead trees, either feeding on the phloem (‘bark beetles’ subgroup) or on fungi inoculated into the sap...

Curculionidae Scolytinae are one the most successful groups of invading insects worldwide and amongst the most important wood-boring Coleoptera introduced to Europe.These beetles are generally moved among continents within live plants, timber, containers, pallets and wood-packaging materials, and their introduc- tion may result in substantial econo...

Baited traps are a basic component of both specific and generic surveillance programs targeting wood-boring beetles at risk of introduction to new habitats because of global trade. Among the numerous protocols developed over the years for generic surveillance of longhorn beetles, jewel beetles, and bark and ambrosia beetles is the simultaneous use...

Tribes Coriacephilini, Corthylini, Cryphalini, Ernoporini, Trypophloeini, Xyloctonini, and Xyloterini (Coleoptera: Curculionidae; Scolytinae) include spermophagous, phloeophagous, and xylomycetophagous species. Besides direct damage caused by burrowing into host plant tissues, some species are vectors of aggressive pathogens causing plant dieback a...

A large proportion of the insects which have invaded new regions and countries are emerging species, being found for the first time outside their native range. Being able to detect such species upon arrival at ports of entry before they establish in non-native countries is an urgent challenge. The deployment of traps baited with broad-spectrum semi...

Xyleborini is the largest tribe of Scolytinae accounting for about 1300 species worldwide; all species are primarily xylomycetophagous, developing on symbiotic fungi farmed in plant woody tissues. Xyleborini wood-boring action, associated with the inoculum of symbiotic fungi, can lead, sometimes, to the emergence of host plant dieback, wood damage...

Background: Bark and ambrosia beetles (Coleoptera, Scolytinae) are amongst the most important wood- boring insects introduced to Europe. During field investigations conducted between 2019 and 2021 in different countries and regions of Europe, many exotic species have been recorded providing new and relevant data. New information: Dryoxylon onohara...

Citrus Longhorn Beetle (CLB), Anoplophora chinensis (Coleoptera: Cerambycidae) is a highly polyphagous species native to eastern and south‐eastern Asia. In 2000, an outbreak of A. chinensis was detected in Lombardy Region (Italy). In 2017, an extensive trapping experiment was conducted at three infested sites in order to evaluate the effectiveness...

The Walnut Twig Beetle (WTB), Pityophthorus juglandis Blackman, is a small bark beetle native to Mexico and Southwestern USA recorded for the first time in Europe (NE Italy) in 2013. WTB attacks walnut ( Juglans spp.) and wingnut trees ( Pterocarya spp.) and is the vector of Geosmithia morbida Kolarík et al., a pathogen causing the thousand cankers...

The Asian Longhorn Beetle (ALB), Anoplophora glabripennis (Coleoptera: Cerambycidae), is an important and extremely polyphagous wood-boring beetle native to Asia. In the 1990s, ALB was accidentally introduced into North America and Europe. In 2009, a large ALB infestation was found in the Veneto Region (north-eastern Italy), in the municipality of...

The number of introductions of alien insect has been increasing in the last decades, primarily transported in shipping containers. The attraction of light of different wavelengths (white, infrared, ultraviolet, and red) applied on sticky traps was tested for the development of new traps for hitchhiker insects. The addition of en-tomological glue an...

Bark and ambrosia beetles are commonly moved among continents within timber and fresh wood-packaging materials. Routine visual inspections of imported commodities are often complemented with baited traps set up in natural areas surrounding entry points. Given that these activities can be expensive, trapping protocols that attract multiple species s...

Insects are one of the most successful groups of invasive species, and the number of new introductions has been increasing in the last decades. Insect invasions are affected mainly by the increase in international trade, as most of them travel across the world inside shipping containers. The effectiveness of sticky light traps was tested for the in...

Longhorn beetles are among the most important groups of invasive forest insects worldwide. In parallel, they represent one of the most well‐studied insect groups in terms of chemical ecology. Longhorn beetle aggregation‐sex pheromones are commonly used as trap lures for specific and generic surveillance programs at points of entry and may play a ke...

Longhorn and jewel beetles are often moved intercontinentally within woody materials. The common use of hardwoods in solid wood-packaging requires e cient trapping protocols for broadleaf-associated species. We tested the e ect of lure (ethanol vs multi-lure), trap color (green vs purple), and trap height (understory vs canopy) on the longhorn and...
