The Popillia japonica, commonly known as the Japanese beetle, is causing concern in Lombardy, where damage to gardens and crops has been reported. The first signs of its presence emerged at the end of May, with a peak in adult specimens expected to decline only by mid-August. This beetle, native to Asia and first identified in Europe in 2014, is now widespread across almost all provinces in Lombardy, with the exception of Mantua. The regional councilor for Agriculture, Alessandro Beduschi, emphasized the importance of citizen collaboration in monitoring and controlling the infestation.
To address the issue, the Lombardy Region has activated a control network with 20 detection sites and a plan that includes 1,200 “attract and kill” devices to limit the spread of the Japanese beetle. Manual collection of the insects in private gardens is recommended, while the use of commercial traps is discouraged as they could exacerbate the situation. Although damage has so far been contained thanks to the measures implemented, it is crucial to maintain vigilance and follow the guidelines to prevent further problems related to this invasive species.
