(ANSA) - Rome, May 5 - Bees are repopulating northern Italy thanks to a ban on new types of pesticides believed responsible for decimating them, the Italian Beekeepers Association announced on Tuesday. UNAAPI Chairman Francesco Panella said the return of the bees in the fields of northern Italy ``proved that their decimation is directly linked to the ban on neonicotinoids``introduced by the agriculture ministry last September.
