日本金龜子肆虐意大利北部葡萄园和果园

原产于日本的日本金龜子自2014年首次在米兰马尔彭萨机场附近被检测到后，已在意大利北部迅速蔓延1。这种害虫目前已侵入伦巴第、皮埃蒙特和瓦莱达奥斯塔地区1。

日本金龜子因缺乏天敌且食性广泛而构成严重威胁。该害虫的食谱涵盖超过300种植物和树木1，已被欧盟列为优先防治对象。农业游说团体Coldiretti的负责人Lorenzo Bazzana指出，在某些地区甲虫已摧毁了收成1。

米兰大学昆虫学家Daniela Lupi表示，虽然这种害虫对人类无危险，但生产量会大幅降低1。各地农民正面临严重损失，为应对这一挑战，相关方面正尝试通过引入寄生虫、信息素陷阱和农药等手段进行防控。

The Japanese beetle, a species native to Japan, is rapidly advancing through northern Italy, posing a serious threat to local vineyards and orchards 1. First detected near Milan's Malpensa Airport in 2014 1, the pest has since spread across Lombardy, Piedmont, and Valle d'Aosta 1.

The insect's wide-ranging appetite makes it particularly destructive. Its diet encompasses more than 300 plant and tree species 1, allowing it to damage diverse crops across agricultural regions. The European Union has designated it as a priority pest species due to its lack of natural predators in the region and its capacity for rapid proliferation 1.

The damage to local agriculture has been substantial. Lorenzo Bazzana, a representative of Coldiretti, the agricultural lobbying group, noted that in some areas the beetles have destroyed entire harvests 1. Daniela Lupi, an entomologist at the University of Milan, cautioned that while the insects pose no danger to humans, they will significantly reduce crop yields 1.

Authorities and researchers are pursuing multiple control strategies, including the introduction of parasitic insects, pheromone traps, and pesticides 1, though the beetle's continued spread underscores the challenge farmers face in managing this invasive species.
