Tutte le colonie di api della Svizzera sono affette da malattie croniche, avverte l’apicoltore Peter Neumann. “Se gli apicoltori non intervengono, tra uno o due anni tutte le colonie saranno morte”.
Le api sono infettate dall’acaro Varroa, afferma Neumann in un’intervista trasmessa venerdì da CH Media. “Ci sono altri virus che non hanno nulla a che fare direttamente con l’acaro. Nel complesso, le colonie sono così indebolite che anche i virus normalmente non dannosi rappresentano un pericolo.
Per migliorare la situazione, spiega l’esperto, sono necessarie tre cose: una maggiore e migliore informazione per gli apicoltori e il pubblico in generale, lo sviluppo di metodi di protezione per tutte le api e, per le api mellifere, una ricerca intensiva su una strategia sostenibile contro l’acaro Varroa.
