‘Make noise and don’t panic’: India tries to ward off locust invasion

Delhi braces for swarm while farmers in badly-hit north play loud music and honk car horns to try to prevent decimation of fields

Residents of Delhi are bracing themselves for a possible invasion of locusts, which have been ravaging areas in the north of the country.

A change in wind direction could save the city, but Dr K L Gurjar, deputy director of the Locust Warning Organisation, has warned residents to be prepared to make a lot of loud noise so that instead of settling, they keep flying and fly past the city. And don't panic".
