“…Of the ca. 350 species of bark beetles (Coleoptera: Curculionidae) known to occur in Western Europe [12], 42 species live only or mainly on Mediterranean conifers, and are mostly associated with pines [13]. Although some species are endemic and have restricted distribution, others are found in several countries or in the entire Mediterranean basin, including primary forest pests such as pine shoot beetles (Coleoptera: Curculionidae) of the genus Tomicus, which are known plausible vectors of F. circinatum [14].…”

“…Other noteworthy bark beetles in the Mediterranean zone are Ips and Orthotomicus species, many of which have been associated with high pine mortality or reduced forest health following drought episodes or forest fires [13]. Species associated with pine mortality include Ips sexdentatus (Börner, 1776) [31][32][33][34][35], Ips acuminatus (Gyllenhal, 1827) [36], and Orthotomicus erosus (Wollaston, 1857) [37,38].…”

Pine pitch canker (PPC), caused by the pathogenic fungus Fusarium circinatum (Nirenberg and O' Donnell), is a serious threat to pine forests globally. The recent introduction of the pathogen 2 of 34 to Southern Europe and its spread in Mediterranean region is alarming considering the immense ecological and economic importance of pines in the region. Pines in forests and nurseries can be infected, resulting in severe growth losses and mortality. The pathogen is known to spread in plants for planting and in seeds, and results from recent studies have indicated that F. circinatum may also spread through phoretic associations with certain insects. With this review, we aim to expand the current understanding of the risk of insect-mediated spread of PPC in different parts of Europe. Through the joint action of a multinational researcher team, we collate the existing information about the insect species spectrum in different biogeographic conditions and scrutinize the potential of these insects to transmit F. circinatum spores in forests and nurseries. We also discuss the impact of environmental factors and forest management in this context. We present evidence for the existence of a high diversity of insects with potential to weaken pines and disseminate PPC in Europe, including several common beetle species. In many parts of Europe, temperatures are projected to rise, which may promote the activity of several insect species, supporting multivoltinism and thus, further amplifying the risk of insect-mediated dissemination of PPC. Integrated pest management (IPM) solutions that comply with forest management practices need to be developed to reduce this risk. We recommend careful monitoring of insect populations as the basis for successful IPM. Improved understanding of environmental control of the interaction between insects, the pathogen, and host trees is needed in order to support development of bio-rational strategies to safeguard European pine trees and forests against F. circinatum in future.

“…In contrast, most species from the parental clade Ipini are bark beetles, highly specific to their host trees (Wood 1982), with little or no known relationship with fungi, and the fungi isolated from them are usually non-specific commensals (Yamaoka et al 1997, Kopper et al 2004). This indicates that Premobiini are an independent origin of the ambrosia symbiosis within a bark beetle clade (Alamouti et al 2007, Alamouti et al 2009, Lieutier et al 2016. A comparative analysis of Premnobiini and its sister taxa, and a contrasting analysis of similarly evolved ambrosia clades, could illuminate how these specific associations evolve.…”

“…Introduction. Health condition of Scots pine (Pinus sylvestris L.) stands worsens in recent decades in many regions, including northern (Siitonen 2014) and southern countries (Lieutier et al 2016, Pineau et al 2017, as well as Belarus (Sazonov et al 2017) and Ukraine (Borodavka et al 2017, Meshkova andBorysenko 2017).…”

The aim of the research was to reveal the features of Scots pine stands decline in Zhytomyr (Central) Polissya using the case of Korostyshiv Forest Enterprise. The investigations included statistical and comparative analysis of the database of forest fund of the State Association "Ukrderzhlisproekt", the data of forest pathological survey of pine stands in Korostyshiv Forest Enterprise and reports on sanitary felling in 2014-2017. Bark beetles (72.4-95.8 %), fungal diseases (0.4-9.1 %) and weather conditions (3.5-27.5 %) were the main causes of Scots pine decline. A high proportion of pure Scots pine stands and the stands over 50 years old are the main predisposing factors of forest decline. Abnormal increase in air temperature and a decrease in Selyaninov's Hydro-thermal Coefficient to the level of Steppe zone were inciting factors of forest decline, and bark beetles were a contributing factor to it. K e y w o r d s : Scots pine (Pinus sylvestris L.), forest decline, Selyaninov's Hydro-thermal Coefficient, forest composition, age structure, relative density of stocking. *
