“…They also provide valuable interception data that can be used to predict likely future introductions (Brockerhoff et al 2006a). This is especially the case for the introduction of insect pests of eucalypts, where confirmed pathways for most introductions are lacking.…”

“…For forest insect pests in general, two of the most common pathways of introduction are untreated wood products (Brockerhoff et al 2006a;Haack 2006;Skarpaas and Økland 2009) and live plant material (Kenis et al 2007;Roques et al 2009;Liebhold et al 2012). Because wood and barkassociated insects comprise only a minor proportion of eucalypt insect pests that have been introduced into new areas (Figure 3), the introduction of wood products is probably not a major current pathway for the introduction of these insects.…”

Increasing numbers and intercontinental spread of invasive insects on eucalypts

et al. 2016

Native to Australasia, Eucalyptus (sensu lato) is one of the most planted genera of trees in the world. However, the sustainability of Eucalyptus species as plantation trees in non-native areas is increasingly threatened by the introduction and spread of Eucalyptus-feeding insects fromAustralia. We examine patterns and potential trends with respect to the global spread of Eucalyptusfeeding insects. Likely pathways of introduction and drivers of the rapid distribution of these insects, as well as management options are considered. The rate of introductions is shown to have increased nearly fivefold since the 1980s. As a result, the number of non-native pests of eucalypts outside of Australia has doubled in less than three decades. Furthermore, the rate of secondary spread among continents has also increased. Surprisingly, we found no association between area planted and the number of pests or new introductions. Only a small number of countries have been the points of first detection outside the native range; these countries have acted as bridgeheads to other regions.Quarantine regulations aimed at reducing the spread of invasive organisms appear to be ineffective at a global scale, and pathways allowing these invasions to occur are poorly understood or unknown. An expanded suite of management options are needed to provide resilience against the rapid accrual and homogenization of eucalypt pests, thereby ensuring the sustainability of eucalypt forestry worldwide.

“…While tree pests often spread naturally and a number of ecological factors contribute to the abundance and extent of pests once established, human activities such as the movement of plants and wood products along trade routes play an important role in the international and national spread of pests (Gilbert et al 2003). The primary means through which forest pests are introduced into new environments previously free of infestation or disease are imports such as seeds, seedlings, tubers, and live plants (USDA 2005;Brasier 2008;EPPO 2012;Liebhold et al 2012) as well as wood and wood packaging (Haack 2001(Haack , 2006Brockerhoff et al 2006;Ciesla 2011;Stenlid et al 2011).…”

Part of the solution? Stakeholder awareness, information and engagement in tree health issues

The dangers posed to wooded environments from tree pests introduced by the expansion of international trade in live plants and the continued use of wood packaging in transporting materials have been widely accepted. A lack of awareness of the issues amongst key stakeholders involved in the movement of these materials can hamper an effective response as their unaltered behaviours continue to have unintended consequences. Better communication and engagement is needed to enrol this wider range of actors, such as plant buyers, traders and woodland owners, in preventative action or mitigation of tree pest impacts. However, as this review paper shows, current published evidence on awareness levels and effective engagement methods is limited, and lessons must be sought from research into other closely related issues such as invasive plants. We provide a summary of this available evidence, related to key stakeholder groupings, their levels of awareness and current modes of information provision and reception. It show what can at best be described as mediocre levels of awareness, and highlights the role of traditional media, such as television and newspapers, as sources of information. It further notes the urgent need for research to more fully map the tree health stakeholder landscape and to further our understanding of how to increase awareness and effect changes in behaviour.

“…Based on the current trend on the spread of invasive insect pests of forestry trees (Brockerhoff et al, 2006a;Tobin, 2015) (Haack et al, 2014) should assist in decreasing the rate of spread of these insects, although it is unlikely to completely stop such movement (Brockerhoff et al, 2006b). Though most Pissodes spp.…”

Department, Uruguay) are acknowledged for providing dead insect specimens. We also thank the two anonymous reviewers for their constructive suggestions and comments. AbstractDuring the first half of the twentieth century, two accidental cases of introduction of Pissodes weevils were recorded from the southern hemisphere. The weevils in South Africa were identified as the deodar weevil (Pissodes nemorensis) and those in South America as the small banded pine weevil (Pissodes castaneus). Wide distribution of the two species in their invasive range, general difficulty in identifying some Pissodes spp., and the varying feeding and breeding behaviours of the species in South Africa has necessitated better evidence of 1 species identity and genetic diversity of both species and population structure of the species in South Africa.Barcoding and the Jerry-to-Pat region of the COI gene were investigated. Morphometric data of the South African species was analysed. Our results confirmed the introduction of only one Pissodes species of North American origin to South Africa. However, this species is not P. nemorensis, but an unrecognized species of the P. strobi complex or a hybrid between P. strobi and P. nemorensis. Only P. castaneus, of European origin, was identified from South America. We identified ten mitochondrial DNA haplotypes from South Africa with evidence of moderate genetic structure among geographic populations. Terminal leader and bole-feeding weevils did not differ at the COI locus. A single haplotype was identified from populations of P. castaneus in South America. Results of the present study will have implications on quarantine, research and management of these insect species.
