L'inverno relativamente mite appena trascorso potrebbe aver favorito in Svizzera la proliferazione degli insetti sia nocivi, sia “buoni”.
A sostenerlo sono gli esperti dell’istituto Agroscope, stando ai quali con condizioni meteorologiche ideali questa primavera gli attacchi contro la vegetazione potrebbero essere particolarmente violenti. Non solo, dopo un inverno mite, i pidocchi adulti potrebbero diventare portatori di virus dannosi per i cereali.
Particolare attenzione, sottolineano i biologi, dovranno prestare gli amanti delle passeggiate nei boschi poiché le zecche, ma non solo, rischiano quest’anno di essere presenti in maggior numero e attive prima del solito.
