Japanese beetle advances through northern Italy's vineyards and orchards, frustrating farmers
- Shiny green Japanese beetles have swarmed parts of northern Italy, chewing leaves on orchards and terraced vineyards and threatening grape ripening and historic sites.
- The pest feeds on 300+ plant species and its larvae damage lawns and roots; farmers say some harvests are already reduced or lost in the Po Valley.
- Authorities are using pheromone traps, pesticides and even microscopic parasites to attack larvae, but the beetles spread easily by travel, making containment difficult.
