Native or Invasive? The Red-Haired Pine Bark Beetle Hylurgus ligniperda (Fabricius) (Curculionidae: Scolytinae) in East Asia

Abstract

The red-haired pine bark beetle, Hylurgus ligniperda (Fabricius), is one of the most rapidly spreading invasive forest insects. Originally from Eurasia, it has subsequently been introduced to Oceania, North, and South America. Yet, the status of H. ligniperda in East Asia is ambiguous. Here, investigation and analysis were conducted on the beetle in China, South Korea, and Japan. New occurrences in China and South Korea were recorded by field surveys and the expansion of H. ligniperda spreading in East Asia was analyzed. The results show that H. ligniperda is likely an invasive species in East Asia, initially invading Japan, then South Korea. Now it has invaded and successfully colonized Shandong province, China. Furthermore, the species has spread rapidly and it is now widely distributed in South Korea and Japan.

Distribution, Invasion History, and Ecology of Non-native Pine Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern South America

“…In this sense, invasions of new regions might originate from previously invaded regions -i.e., "bridgehead effect", (Bertelsmeier and Keller 2018)-. To better understand the invasion history and pathways of pine bark beetles in South America, more detailed studies are needed, analyzing for example, interception history of the species in international wood packaging material and reconstructing the invasion histories of established populations based on genetic analysis (Lin et al 2021;Turner et al 2021).…”

Cosmopolitan Scolytinae: strong common drivers, but too many singularities for accurate prediction

“…A dataset of Scolytinae species known to have spread beyond geographical barriers (across seas or oceans in this study) was constructed (Suppl. material 1), including any species distributed across at least one barrier (hereafter designated as "Scolytinae with an invasion history" -SIH), irrespective of its area of origin which is often difficult to delimit (see, for example, Lin et al 2021). The list includes all the Scolytinae species from the EPPO study (EPPO 2020;Grousset et al 2020), as well as the species introduced into North America, New Zealand and Europe, listed respectively by Haack (2001Haack ( , 2006, Brockerhoff et al (2006) and Kirkendall and Faccoli (2010).…”
