Main research question
The proposed Euphresco project aims to consolidate the European studies conducted so far, and, with collaboration from North American researchers, devise a generic trapping technique for Agrilus jewel beetles. It is expected that the project could also contribute to the development of monitoring tools for specific American Agrilus species (e.g. A. anxius, A. bilineatus, A. auroguttatus) and for specific European Agrilus species (e.g. A. biguttatus, A. viridis, A. sulcicollis, A. sinuatus).
The response of native species to a range of green-coloured traps will be studied; all traps, with or without decoy insects, will be compared in Belgium under different conditions. The best trap type will then be equipped with lures. The same trap type, equipped with either lures, will also be deployed in North America, in order to assess its value for the monitoring of A. planipennis and other local species.
The remaining work packages are drawn up with the aim of providing practical tools for future monitoring of target Agrilus spp. by NPPO inspectors, researchers and other people who, in the course of their professional activities, may discover damage from Agrilus spp. (e.g., foresters, fruit tree growers, …).
It is expected that the Agritrap project would contribute to the more global Euphresco project towards the designing of monitoring tools on both sides of the Atlantic. An additional expected outcome for Belgium will be a contribution to our knowledge of the distribution and phenology of local Agrilus species and the identification of sites in the country suitable for monitoring quarantine Agrilus species.
