Japanese beetle spreads through northern Italy's vineyards as pest moves southward

The Japanese beetle has advanced through northern Italy's vineyards and orchards, according to AP News. The pest, Popillia japonica, was documented on vine leaves in Pont Saint Martin, in the Valle d'Aosta region, on 9 July 2026. Farmers in the region are frustrated by the infestation, which threatens both wine production and fruit crops across the agricultural districts of the Alps.

The beetle's northward spread has been tracked for months, but its arrival in established wine country marks a new phase of the invasion. The insect feeds on the leaves, flowers and fruit of hundreds of plant species, causing significant agricultural damage. Valle d'Aosta's wine and apple industries are among Italy's most important, and the pest's presence there signals the vulnerability of central Italian agricultural regions to the same threat.

For Marche, the beetle's advance carries real economic consequence. The region's agricultural districts—particularly in the inland provinces of Pesaro-Urbino and Macerata—depend on fruit, vegetable and wine production. Shoe-making and furniture-making may dominate the regional economy, but agriculture remains a significant employer and export earner. If the Japanese beetle continues its southward march at the pace documented in recent months, Marche's orchards and vineyards could face infestation within one to two seasons, threatening crop yields and labour-intensive harvest operations.
