Fusarium circinatum, the causal agent of pine pitch canker (PPC), is currently one most important threats Pinus spp. globally. This pathogen known in many pine-growing regions, including natural and planted forests, can affect all life stages trees, from emerging seedlings to mature trees. Despite importance PPC, global distribution F. circinatum poorly documented, this problem also true hosts within countries that are affected. The aim study was review with a particular focus on Europe. We...
Summary Dothistroma needle blight ( DNB ) caused by septosporum and pini is a damaging disease of pine in many countries. The led to the abandonment planting susceptible Pinus species parts Africa, Asia, Australasia, Europe North America. Although can be effectively controlled using copper fungicides, this chemical only routinely applied forests New Zealand Australia. Other management tactics aimed at making conditions less favourable for development, such as thinning or pruning, may...
Pines are major components of native forests and plantations in Europe, where they have both economic significance an important ecological role. Diseases pines mainly caused by fungal oomycete pathogens, can significantly reduce the survival, vigor, yield individual trees entire stands or plantations. Pine pitch canker (PPC), Fusarium circinatum (Nirenberg O’Donnell), is among most devastating pine diseases world, example emergent invasive disease Europe. The effects microbial interactions...
Monitoring the structure parameters and damage to trees plays an important role in forest management. Remote-sensing data collected by unmanned aerial vehicle (UAV) provides valuable resources improve efficiency of decision making. In this work, we propose approach enhance algorithms for species classification assessment vital status stands using automated individual tree crowns delineation (ITCD). The can be potentially used inventory identifying health regional-scale areas. proposed ITCD...
A large proportion of the insects which have invaded new regions and countries are emerging species, being found for first time outside their native range. Being able to detect such species upon arrival at ports entry before they establish in non-native is an urgent challenge. The deployment traps baited with broad-spectrum semiochemical lures ports-of-entry other high-risk sites could be one early detection tool. Rapid progress identification semiochemicals cerambycid beetles during last 15...

As a result, 126 taxa from six subfamilies were established, as follows: Prioninae (four taxa), Lepturinae (43 Necydalinae (two Spondylidinae (seven Cerambycinae (31 taxa) Lamiinae (39 taxa). In this study, two new records for ( Stenurella nigra Xylosteus spinolae ) localities or additional information 24 cerambycid reported. belong to 18 zoogeographical categories seven...
European forests are threatened by increasing numbers of invasive pests and pathogens. Over the past century, Lecanosticta acicola, a foliar pathogen predominantly Pinus spp., has expanded its range globally, is in impact. acicola causes brown spot needle blight, resulting premature defoliation, reduced growth, mortality some hosts. Originating from southern regions North American, it devastated USA's states early twentieth 1942 was discovered Spain. Derived Euphresco project...
The longhorn beetles fauna of Pirin Mountains, Bulgaria, was studied, based on literature data and original material. As a result, 100 taxa from five subfamilies are listed for the area, as follows: Prioninae (7 taxa), Lepturinae (31 Spondylidinae (9 Cerambycinae (28 taxa) Lamiinae (25 taxa).This study presents two new records Mts.

Summary Dothistroma needle blight ( DNB ), caused by septosporum and pini , brown spot BSNB Lecanosticta acicola are some of the most serious damaging foliar diseases pines Pinus spp.). is reported for first time from Ireland Portugal confirmed Black Sea coast Russia (Krasnodar region, Sochi). It has also been recovered first, only, site in Latvia 4 years after efforts to eradicate it were undertaken. on sylvestris radiata . was found Comunitat Valenciana, Spain, as causal agent disease...
The winter and summer phenological forms of the pine processionary moth ( Thaumetopoea pityocampa ) were recorded in two adjacent sites region Asenovgrad, South Bulgaria. In land Muldava village (at foot Rhodopes at 290 m a.s.l.), typical form was established, while found vicinity Dobrostan (on northern slopes 1200 a.s.l.). calculated air fly distance between both villages is 9.3 km. 2019, funnel automatic pheromone traps – CapTrap® installed to obtain information about...
Massaria disease caused by the fungal pathogen Splanchnonema platani (anamorph Macrodiplodiopsis dermazieresii ) was found for first time in winter of 2023 on fallen branches plane trees ( Platanus × acerifolia park ‘Rupite’, southwestern Bulgaria. In 2023-2024, symptoms were ornamental green city areas Yambol, Gabrovo, Stara Zagora and Sofia.

Over the last ten years, Bulgaria's forest areas have been under almost year-round fire activity, severely impacting Natura 2000 sites: Managing forests and maintaining traditional links between people nature in mountain sites is becoming increasingly challenging. However, National Methodology for determining risk of fires (proposed 2016) applicable only at regional administrative level (NUTS 3). This study motivated by actual need an approach a toolbox that can accurately assess wildfires,...
A comparative analysis of growth rate and health condition 54 Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) provenances was conducted at the age 24 years. The provenance test established in 1990 with 3-year-old (3+0) seedlings planted a 2 × m plot design two replications. which were studied originated from North America separated into coastal, continental Western Cascade groups. In 2011 terms height, diameter breast height stem volume. assessed by evidence symptoms degree defoliation...
Fusarium circinatum Nirenberg & O’Donnel is listed among the species recommended for regulation as quarantine pests in Europe. Over 60 Pinus are susceptible to pathogen and it also causes disease on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) genera such Picea Larix. The European Food Safety Authority considers probability of new introductions—via contaminated seeds, wood material, soil growing substrates, natural means human activities—into EU very likely. Due early detection,...
Dothistroma septosporum, the primary causal agent of needle blight, is one most significant foliar pathogens pine worldwide. Its wide host and environmental ranges have led to its global success as a pathogen severe economic damage forests in many regions. This comprehensive population study elucidated historical migration pathways reveal Eurasian origin fungus. When over 3800 isolates were examined, three major clusters revealed: North America, Western Europe, Eastern with distinct...

Intensive forest afforestation with native pine species was developed in the 1960s on degraded and deforested lands region of Eastern Rhodopes (south-eastern Bulgaria). Severe damage by wet snow registered coniferous forests March 2015. In following years, bark beetle attacks were broken felled fresh wood. As a result, infestation spots appeared plantations. period 2019–2021, caused beetles assessed State Forestry Kirkovo (the Rhodopes, south-eastern An integrated approach using data...
In 2020 and 2021, chalcidoid parasitoids (Hymenoptera, Chalcidoidea) of bark beetles in pine ( Pinus spp.) plantations were studied Bulgaria. Samples (cuttings stems branches) trees infested by collected from seven sylvestris P. nigra From each sampling plot, five cuttings placed photoeclectors laboratory conditions (18-22ºC). Emerged regularly gathered fixed ethanol. Six parasitoid species - Dinotiscus colon , Metacolus azureus M. unifasciatus Rhopalicus quadratus R. tutela (Chalcidoidea:...
Abstract For non-native tree species with an origin outside of Europe a detailed compilation enemy including the severity their attack is lacking up to now. We collected information on native and attacking trees, i.e. type, extent time first observation damage for 23 important trees in 27 European countries. Our database includes about 2300 synthesised records (synthesised per biotic threat, country) from over 800 species. Insects (49%) fungi (45%) are main observed threats, but also...
