Worldwide distribution and theoretical spreading of Trichoferus campestris (Coleoptera: Cerambycidae) depending on the main climatic elements

Abstract

The velvet longhorned beetle, Trichoferus campestris (Coleoptera: Cerambycidae) is a serious wood‐boring pest that is a major threat to the phytosanitary condition of forests and orchards. Its worldwide expansion is a major concern for plant health. We have collected all bibliographical references, phytosanitary reports and authentic photographic evidence from entomological websites to determine the worldwide distribution of T. campestris. The theoretical directions of the spreading and actually occupied area of this arthropod pest were determined over the whole Holarctic range. Furthermore, the potential distribution area was calculated using cumulated temperature in the growing season averaged over 15 years both in the Palearctic and Nearctic regions. Holarctic expansion of the species, including the main parts of North America and Eurasia, is clearly indicated. Its populations occur in 29 countries to date, supported by documentation from 64 publications and 30 online forums. Its spread is continuously westward in the Palearctic; in the Nearctic, the spread was first southward from the Great Lakes region then eastward from Utah. The species has excellently adapted to circumstances of freight by ship and plane, as wood is often used, ensuring optimal conditions for the pest. In addition, the active spreading achieved by flying is an important factor contributing to its expansion. The primary criterion for controlling the species would be the introduction of a monitoring system in affected and exposed areas.

The first molecular insight into the genus Turanium Baeckmann, 1922 (Coleoptera: Cerambycidae: Callidiini) with a description of a new species from Middle Asia

“…One example could be velvet longhorned beetle, Trichoferus campestris-a relatively closely related (Cerambycinae: Hesperophanini) species with a similar bionomy, native to this region but, unlike Turanium, also to highly industrialized China, that is considered a serious wood-boring pest and one of the most rapidly spreading cerambycids (e.g. Grebennikov et al 2010;Dascălu et al 2013;Keszthelyi et al 2019).…”

Geographical dispersion of ragweed leaf beetle (Ophraella communa) based on climatic and biological characters in the Palearctic habitats

“…Papers about the theoretical spread of some insect species depending on climatological factors and biological constants as well as the windmediated spread in new habitats (Gui et al, 2012;Nathan et al, 2003) were recently published Keszthelyi, 2021;Keszthelyi et al, 2019;. According to Meng et al (2007).…”

Notes on the larval morphology of Trichoferus campestris (Coleoptera, Cerambycidae), a wood borer frequently intercepted in wood packaging material

“…were recorded between 1997 and 2017 (Krishnankutty et al ., 2020). Adults of T. campestris have been reported from many areas in the USA and Canada (Keszthelyi et al ., 2019; Krishnankutty et al ., 2020). Interestingly, records of infested trees appear to be scarce.…”

“…T. campestris has also been intercepted in imported wood or wood packaging material in France, Germany, Austria, the Czech Republic and Sweden (Keszthelyi et al ., 2019). Moreover, adults have been caught in trap surveys in ports in Italy and Austria (Pennacchio et al ., 2016; Hoch et al ., 2016).…”

“…Moreover, adults have been caught in trap surveys in ports in Italy and Austria (Pennacchio et al ., 2016; Hoch et al ., 2016). Populations of T. campestris exist in East and Central European countries, such as the Ukraine, Romania and Hungary; T. campestris is considered likely to have spread westward from Asia north of the Black Sea (Dascalu et al ., 2013; Keszthelyi et al ., 2019). T. campestris was placed on the EPPO A2 list (i.e.…”
