Milioni di api morte, intere popolazioni spazzate via in una sola giornata. È una moria anomala, molto anomale e senza precedenti, quella descritta dagli apicoltori del comune di Zäziswil, nell'Oberland bernese. Da venerdì scorso, giorno in cui sono stati segnalati i primi insetti morti, un terzo delle loro arnie - e in particolare quelle vicine ai frutteti - è stato decimato. Vista la situazione, gli apicoltori temono ora per la sopravvivenza stessa delle popolazioni e puntano il dito contro i pesticidi usati nei campi.
Piccole, instancabili lavoratrici minacciate
Non si esclude un tragico errore. Nei prossimi giorni campioni di foglie ma anche di insetti saranno analizzati per capire cosa abbia provocato la moria.
