Emerald Ash Borer (EAB), Agrilus planipennis, is a beetle that originates from East Asia. Upon invasion to North America in the early 2000s, it killed untold millions of ash trees. In European Russia, EAB was first detected in Moscow in 2003 and proved to have the potential to also kill native European ash (Fraxinus excelsior). The beetle has since...

International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated fungi and insects is needed. We present records of endophytic fungi and insects in twigs of 17 angiosperm and gymnosperm gene...

https://www.mdpi.com/journal/forests/special_issues/invasive_tree_pathogens Dear Colleagues, Forest ecosystems throughout the world are increasingly affected by changing climate, international trade and transport systems. Growing global trade has facilitated the introduction of numerous new tree pathogens into new regions. The focus in a lot of forest research is on modern mechanisms for prevention and management of potential invasions of forest pathogens as well as mitigating the impact of invasive pathogens within forest ecosystems. Less knowledge is available on the biological and chemical control of invasive pathogens. The prevention and control of new invasions is a promising tool to improve forest health in the face of increased climate warming. The emergence of a new invasive forest pathogen appears to demand resources for developing countermeasures, such as breeding resistance programs, development of fungicide, and biocontrol agents. Therefore, there is an urgent need to introduce and synthesize the information that illustrates the impacts of invasions of tree pathogens, their biology, forest management, control measures and their interactions, as well as methods to predict, assess and mitigate these impacts. This Special Issue welcomes studies that consider the recent advances in the development of different measures to prevent the entry and expansion of invasive forest pathogens including their biology, monitoring, epidemiology, ecology, diagnostics, and disease management and control. Thus, this Special Issue promotes the dissemination of knowledge in forest protection for the preservation of diversity and resilience of forest ecosystems. Studies conducted in forests and laboratories, as well as theoretical approaches and literature reviews, are of interest. We encourage studies from broad research topics related to invasive forest pathogens. Dr. Kateryna Davydenko Dr. Ari M. Hietala Guest Editors
