Preparing for invasion: novel techniques for early detection of emerald ash borer (Agrilus planipennis) and discovering resistance traits in host plants.

Project description

Discovering detection methods and plant resistance in European forests

Ash trees (genus Fraxinus) are an important hardwood tree common in forests, parks, and streets in the northern hemisphere. They are also under threat and are being attacked by the emerald ash borer (EAB, Agrilus planipennis). This non-native insect causes mortality of trees in eastern Europe, that will potentially kill tens of millions of ash trees, as has happened in the United States. To prevent the spread of EAB in western Europe, urgent research action is needed. The EU-funded EMERALD project aims to perform innovative, multidisciplinary research combining new techniques, molecular biology, analytical chemistry, and other fields, to find resistance traits in ash trees and formulate early detection methods to slow and potentially stop EAB invasion in European forests.

Objective

Ash trees (Fraxinus spp.) in Europe are threatened by two alien invasive organisms; a deadly fungal pathogen Hymenoscyphus fraxineus that has been causing a slow, steady decline in Europe’s ash population, and emerald ash borer (EAB; Agrilus planipennis), a buprestid beetle that is quickly killing trees in eastern Europe, and moving west. There are fears that EAB will follow the same path as it did recently in USA – killing millions of ash trees, unless active research is undertaken to prevent the spread of EAB and protect the ash resource. EMERALD is a multidisciplinary and innovative project that approaches this invasion through the combination of molecular biology, analytical chemistry, sensor technology, insect ecology, and tree physiology to understand host-pest interactions and improve the options for integrated pest management in European forests. In this project, naïve and a co-evolved ash species will be investigated to understand their attractive volatile chemistry and influence on EAB’s behaviour and host preference (antixenosis), differences in host chemical defenses that either promote or deter EAB performance (antibiosis), and the confounding effect of H. fraxineus in relation to both interactions. Novel early detection tools will be developed including new lure traps and molecular assays based on optimized environmental DNA protocols of samples filtered from stem flow and canopy foliage, and portable loop mediated isothermal amplification (LAMP) to achieve point-of-use and real-time detection of EAB. The training-through-research will diversify and expand the skillset of the applicant, while also providing reciprocal teaching and new insights for the host unit. The results of this project will have tremendous value for European stakeholders and the general public for those concerned with saving the economically and ecological valuable ash in urban and rural forested environments by developing an arsenal of tools to manage the impending EAB invasion.
