“…The first record of X. germanus in Russia was from Krasnodarsk Krai, in the southwestern region of Russia, in 2001 [42]. The occurrence of X. germanus in the Russian far east, near Vladivostok, was later reported by Sweeney et al [43]. Empirical data support that X. germanus is likely established in the Russian far east, but additional collection efforts are required from Krasnodarsk Krai in the southwestern region of Russia.…”

The black timber bark beetle Xylosandrus germanus (Blandford) is an invasive ambrosia beetle that originates from Southeast Asia and has become successfully established within Europe and North America. Herein, we provide a review of the spread and distribution of this tree and timber pest species across Europe, before and after 2000, along with a review of its habitat preferences. Since the spread of X. germanus across Europe has accelerated rapidly post-2000, emphasis is placed on this period. X. germanus was first recorded in Germany in 1951 and since then in 21 other European countries along with Russia. Ethanol-baited traps were deployed in oak, beech, and spruce forest ecosystems in the Western Carpathians, Central Europe, Slovakia, to characterize the distribution and habitat preferences of this non-native ambrosia beetle. Captures of X. germanus within Slovakia have been rising rapidly since its first record in 2010, and now this species dominates captures of ambrosia beetles. X. germanus has spread throughout Slovakia from south-southwest to north-northeast over a period of 5–10 years, and has also spread vertically into higher altitudes within the country. While living but weakened trees in Europe and North America are attacked by X. germanus, the greatest negative impact within Slovakia is attacks on recently felled logs of oak, beech and spruce trees, which provide high quality timber/lumber. We suggest that the recent rapid spread of X. germanus in Central Europe is being facilitated by environmental changes, specifically global warming, and the increasing frequency of timber trade. Recommendations for the management of X. germanus in forest ecosystems are proposed and discussed, including early detection, monitoring, sanitary measures, etc.

“…Thirdly, until recently, when there were no pheromone lures, collecting bark and ambrosia beetles by an axe and chisel was a more difficult and uncertain task than today, especially for rare species. Eloquent is the fact that almost all the data obtained after 1980 on the presence of T. laeve in different places were obtained using traps baited with synthetic attractants [19,21,35,37,44,52,53]. Even in countries with a very rich entomological tradition, there is relatively little historical data.…”

Trypodendron laeve Eggers, 1939 is a species of ambrosia beetle much less known than the other three Trypodendron species occurring in Europe. Its status (native or alien) in Central Europe has been a subject of debate over the past two decades. In Romania, the species was discovered in 2008 and the aim of the research presented in this paper was to investigate its distribution in the Carpathians, mainly at high altitudes (>800 m), in tree stands with Norway spruce (Picea abies [L.] H. Karst). Panel intercept traps baited with synthetic pheromone for Trypodendron lineatum (Olivier, 1795) were used in the spring of 2015, at 31 locations. Adults of T. laeve were caught in 20 of them. Additional observations were made within some studies using similar baits and T. laeve specimens were caught in eight locations. T. laeve was always trapped together with T. lineatum, and at some locations also together with T. domesticum (Linnaeus, 1758) and T. signatum (Fabricius, 1787). In all traps, fewer specimens of T. laeve were caught compared to T. lineatum. The species has a widespread distribution in the mountain regions, within forests composed of native tree species and generally located far away from commercial routes. There, it occurs together with other native species of the same taxonomic genus. It seems to be more abundant at high altitudes, but overall its populations are less abundant than those of T. lineatum.

“…In 2015, CFIA inspectors implemented two new semiochemical sets in order to target different insect taxa. The first semiochemical (i.e., General Longhorn) was attractive to longhorned beetles in the Spondylidinae [57] and Lamiinae subfamilies [70] but, could also capture various bark and ambrosia beetles, due to the addition of ethanol [58]. The second semiochemical set (Pine Sawyer) was attractive to Monochamus (longhorned beetles) species from North America, Europe, and Asia [47,59,60] but the inclusion of ethanol and alpha-pinene also makes it attractive to bark and ambrosia beetles.…”

“…Semiochemicals are communication chemicals to induce inter-or intraspecific interactions between organisms (e.g., decaying trees produce a kairomone that attracts bark beetles) [53]. They have been extensively studied for their ability to attract specific insects [47,[54][55][56][57][58][59][60], especially for monitoring particular groups of beetles and the microorganisms associated with them. With the advances associated with next-generation sequencing (NGS), scientists have used the power of metagenomics for the diagnosis of phytoviruses [42], fungi, and oomycetes [61], and the detection of exotic fungi on asymptomatic live plant material imported into Canada [62].…”

Understanding ecological interactions is a key in managing phytopathology. Although entomologists rely mostly on both traditional molecular methods and morphological characteristics to identify pests, next-generation sequencing is becoming the go-to avenue for scientists studying fungal and oomycete phytopathogens. These organisms sometimes infect plants together with insects. There are many relationships yet to be discovered and much to learn about how these organisms interact with one another. Considering the growing number of exotic insect introductions in Canada, a high-throughput strategy for screening those insects is already implemented by the Canadian Food Inspection Agency (CFIA). However, no plan is deployed to investigate the phytopathogenic fungal and oomycete species interacting with insects. Metagenomics analysis was performed on the preservation fluids from CFIA’s insect traps across Canada. Using the Ion Torrent PGM technology and fusion primers for multiplexing and indexing, community profiling was conducted on the different semiochemicals used in the insect traps and the various areas where these traps were placed. Internal transcribed spacer 1 (fungi and oomycetes) and adenosine triphosphate synthase subunit 9-nicotinamide adenine dinucleotide dehydrogenase subunit 9 spacer amplicons were generated. Although direct links between organisms could not be established, moderately phytopathogenic fungi (e.g., Leptographium spp. and Meria laricis) and oomycetes (mainly Peronospora spp. and Pythium spp.) unique to every type of semiochemical were discovered. The entomopathogenic yeast Candida michaelii was also detected. This project demonstrated our ability to screen for unwanted species faster and at a higher scale and throughput than traditional pathogen diagnostic techniques. Additionally, minimal modifications to this approach would allow it to be used in other phytopathology fields.
