Main research question/goal
This research project, part of the transnational EUPHRESCO network, further develops the ILVO expertise on the Little Cherry Disease. The project aims to share the know-how surrounding distribution, epidemiology and diagnostics with a large group of international stakeholders. In concrete terms, the project consortium is working on better and more standardized detection of the disease, taking into account the large variability of the two viruses involved that cause the disease. We map how intensively the disease occurs regionally in Europe (epidemiology) and which factors play a role in the distribution (which vectors? Which reservoir plants, other than Prunus species in the fruit and floriculture sector? Which cultivation practices, etc.). Little Cherry Virus or LChV can cause economic and ecological damage. For example, contaminated sweet and sour cherry cherries produce much less and extremely small fruits. 

Research approach
ILVO collects a series of European LChV isolates via an extensive existing scientific network, and by extension also some non-EU isolates that are subject to EU quarantine legislation. Research on this increases the knowledge about the spread, the complexity, and variability of the disease. At the same time, we will broaden the choice and efficiency of the existing detection methods, for example by exchanging experience inside and outside the research consortium, but also through a comparative test between laboratories. This will help to standardize the detection method, together with the knowledge about the variability of both viruses (LChV-1 and LChV-2). 

We expect our recommendations for diagnostics to lead to an EPPO standard. In countries where the disease was not followed up until recently this improved diagnosic technique could lead to a first determination, discovery of other viruses, and/or variants of the known little cherry viruses that play a role in this disease. The project contributes to an international policy on complementary knowledge in PRA studies (Pest Risk Assessment) and status maps. The sensitization surrounding the EU-wide dissemination and management of LChV will also get a boost.
