"We are walking on locust carpets," Coldiretti said in a statement.
The locusts have destroyed 2,500 hectares (6,200 acres) of agricultural land in the province of Nuoro, between the towns of Ottana and Orani.
Coldiretti fears it may be too late for this year's crop, but preventative measures should be put in place for next year.

The invasion of the tropical grasshoppers has been described by experts as the worst in the region in 60 years.
