Novel genotypes often arise during biological invasions, but their role in invasion success has rarely been elucidated. Here we examined the population genetics and behavior of the fungus, Leptographium procerum, vectored by a highly invasive bark beetle, Dendroctonus valens, to determine whether genetic changes in the fungus contributed to the invasive success of the beetle-fungal complex in China. The fungus was introduced by the beetle from the United States to China, where we identified…

Chemical Signals of Vector Beetle Facilitate the Prevalence of a Native Fungus and the Invasive Pinewood Nematode

The results suggest that the vector beetles promote Sporothrix sp.

The symbiotic complex of Dendroctonus simplex: implications in the beetle attack and its life cycle

Investigation of the bacterial and fungal microbiota of this beetle pest throughout its ontogeny by high-throughput sequencing indicates that a symbiotic association between the eastern larch beetle and some of these microorganisms takes place and that this D. simplex symbiotic complex is helping the insect to colonize its host tree and survive the conditions encountered.

Does cryptic microbiota mitigate pine resistance to an invasive beetle-fungus complex? Implications for invasion potential

It is demonstrated that cryptic microbiota mitigates native host plant phenolic resistance to an invasive symbiotic complex, suggesting a putative mechanism for reduced biotic resistance to symbiotic invasion.

Landscapes drive the dispersal of Monochamus alternatus, vector of the pinewood nematode, revealed by Whole-genome resequencing

It is highlighted that human-mediated transport via roads was likely to be the main factor leading to the long-distance invasion of M. alternatus, whereas non-host landscapes could suppress the spread of this species and may be useful to control the PWD dispersed by M. alternateatus.

Fungal associates of an invasive pine-infesting bark beetle, Dendroctonus valens, including seven new Ophiostomatalean fungi

Seven of the undescribed taxa collected during surveys of the red turpentine beetle’s fungal associates were further characterised based on their morphological characteristics and multi-gene phylogenies, enhancing the ability to accurately assess and predict the risks of invasions by these and related fungi.

The complex symbiotic relationships of bark beetles with microorganisms: a potential practical approach for biological control in forestry.

The latest scientific discoveries in multipartite symbiosis have unravelled unexpected opportunities in bark beetle pest management, which are discussed in this article.

Laurel Wilt in Natural and Agricultural Ecosystems: Understanding the Drivers and Scales of Complex Pathosystems

The rapid spread of laurel wilt in the United States is due to an efficient vector, X. glabratus, and the movement of wood infested with the insect and pathogen, which severely constrain the disease’s management in forest ecosystems and avocado production areas.

First Record of A New Microsporidium Pathogenic to the Eucalyptus Snout Beetle in Brazil

Findings provide insights on the natural occurrence of this novel pathogen for potential use in biocontrol of this invasive pest in Eucalyptus plantations in Brazil, and prompts the design of conservative or augmentative strategies for the establishment of this microsporidium in field populations for sustainable management of eucalyPTus snout beetles.

Seed wasp invasions promoted by unregulated seed trade affect vegetal and animal biodiversity.

Seeds of Douglas-fir, true cedars, true firs and wild roses were sampled all over Europe, and the relative importance of the native and invasive chalcid species was assessed as well as their specific impact on seed yield.



Complex interactions among host pines and fungi vectored by an invasive bark beetle.

It is raised the possibility that interactions among the fungal associates of D. valens and their pine hosts in China may confer advantages to these strains of L. procerum and, by extension, to the beetles themselves, which may enhance invasion by the beetle-fungal complex.

The role of phytopathogenicity in bark beetle-fungus symbioses: a challenge to the classic paradigm.

It is suggested that, rather than playing a supporting role for the host beetle (tree killing), phytopathogenicity performs an important roles for the fungi and may mediate competitive interactions among fungi and support survival and efficient resource capture in living, defensive trees.

Interactions among Scolytid bark beetles, their associated fungi, and live host conifers.

Scolytid bark beetles that colonize living conifers are frequently associated with specific fungi that are carried in specialized structures or on the body surface, suggesting that there is mutual benefit to the fitness of both beetles and fungi.

Assessing the virulence of four bark beetle-associated bluestain fungi using Norway spruce seedlings

In inoculation of seedlings seems to be a reliable, inexpensive and convenient bioassay for determining the virulence of bark beetle-associated bluestain fungi, which agrees largely with results from a previous mass inoculation study using the same isolates inoculated into 40-year-old Norway spruce trees.

The red turpentine beetle, Dendroctonus valens LeConte (Scolytidae): an exotic invasive pest of pine in China

An exotic invasive pest of pines, the red turpentine beetle, Dendroctonus valens LeConte (Scolytidae) (RTB), was first detected in Shanxi Province, northern China, in 1998 and has spread to three adjacent provinces, causing unprecedented tree mortality.

Increased genetic variation and evolutionary potential drive the success of an invasive grass

The results show that repeated introductions of a single species may inadvertently create harmful invaders with high adaptive potential, and multiple immigration events may trigger future adaptation and geographic spread of a species population by preventing genetic bottlenecks and generating genetic novelties through recombination.

Response to Host Volatiles by Native and Introduced Populations of Dendroctonus valens (Coleoptera: Curculionidae, Scolytinae) in North America and China

The responses of D. valens to various monoterpenes are investigated across a wide range of sites across North America and one site in China, and the resulting information is used to develop an optimal lure for monitoring populations of D., valens throughout its Holarctic range.

Reduced genetic variation and the success of an invasive species.

Using microsatellite markers, it is shown that a population bottleneck has reduced the genetic diversity of introduced populations, and this loss is associated with reduced intraspecific aggression among spatially separate nests, and leads to the formation of interspecifically dominant supercolonies.

Red Turpentine Beetle, Dendroctonus valens LeConte (Coleoptera: Scolytidae), Response to Host Semiochemicals in China

Abstract The response of the introduced red turpentine beetle, Dendroctonus valens LeConte, to host semiochemicals in Shanxi Province, China, was distinctly different from that reported in previous

Pathogenicity of Leptographium Species Associated with Loblolly Pine Decline.

Freshly lifted seedlings and 21-year-old trees of loblolly pine were wound-inoculated with Leptographium species recovered from the soil and/or roots of trees with Loblolly decline symptoms in central Alabama and L. lundbergii were the most aggressive and may pose the greatest threat to lobl Polly pines.
