The invasion of the Japanese beetle, Popillia japonica, threatens the entire agricultural sector, urban landscapes, and the biodiversity in invaded areas. Climate suitability puts at risk an area ranging from the Atlantic to the Black Sea, and from the Mediterranean to Great Britain and Southern Scandinavia. The H2020 Project IPM-Popillia will make detection, identification, and monitoring of the new pest faster, more efficient and less labour intensive. IPM-Popillia will unveil the drivers and mechanisms determining success or failure of an invasive species’ population development. IPM-Popillia will provide an “IPM-Toolbox” for sustainable control of the invasive pest in Europe
