La città di Zurigo intensifica la lotta alla popolazione di coleotteri giapponesi (popillia japonica), scoperta per la prima volta a Nord delle Alpi a Kloten la scorsa estate. I campi da calcio della città verranno coperti con teloni per diversi mesi, dopo che le misure precedenti non sono riuscite a sradicare il parassita, che a Sud delle Alpi è già presente dal 2017.
La copertura dei campi da calcio dell’agglomerato urbano è una delle misure più importanti contro il coleottero giapponese, hanno dichiarato martedì le autorità di Zurigo ai media. Le aree erbose rimarranno coperte fino alla fine della stagione di volo dei coleotteri, a fine estate.
Secondo gli esperti, il terreno dei campi da calcio è infestato dalle larve di questi parassiti. Coprendo queste superfici, le larve, diventate coleotteri, non possono più volare via.
Allarme per il coleottero giapponese
