Millions of locusts swarmed the island, while the most affected areas were Nuoro, Ottana and Orani, according to Italian farmers association Coldiretti.

The locust invasion is the worst in the area in 60 years, local entomologist Ignazio Floris told Italian daily, La Stampa.

La Stampa reported that at least 12 farms have been affected by the invasion, leaving grazing pastures ruined and “little left to harvest”.

The plague has been linked to a recent rise in temperatures following months of cooler weather on the island, with many of the young insects emerging from uncultivated land.

Cultivating land for crops discourages the insects laying their eggs in the autumn and prevents them reaching maturity in the summer warmth.

“The locusts emerge on uncultivated land but then they go to cultivated land to eat,” Coldiretti said, adding that there is no current solution to the invasion.
