Locusts reach national capital outskirts; south, west Delhi on high alert

With swarms of locusts descending on neighbouring Gurugram, Delhi Environment Minister Gopal Rai on Saturday asked the national capital's south and west districts' administrations to remain on high alert, said officials.

According to an official who attended the meeting, the minister was informed that a small swarm of locusts has also reached the Asola Bhatti area in South Delhi.

The Agriculture Department has been asked to issue a detailed advisory to all district magistrates and sub-divisional magistrates to deal with a possible locust attack in Delhi.

The minister also asked Forest Department to play DJs, beat drums and dhols to repel the swarms of locusts, the official said.

Rai also asked officials of the Agriculture Department to make field visits to areas close to Gurgaon.

The development secretary, divisional commissioner, director, agriculture department and district magistrates of South Delhi and West Delhi attended the meeting, the official said.

Earlier in the day, the skies over many parts of Gurgaon turned dark as swarms of locusts descended on the town.

The migratory pests, however, are likely to spare the national capital for now, said officials.

The swarms of locusts, spread across two kilometres, moved from west to east. They entered Gurgaon around 11.30 am, K L Gurjar of the Locust Warning Organisation, the Ministry of Agriculture, told PTI.

The pests, he said, were headed towards Faridabad and Palwal in Haryana.

Alarmed at the invasion by locusts, which settled on trees, rooftops and plants, many residents of Gurugram shared videos from their high-rise perches.

In May, India battled a devastating desert locust outbreak. The crop-destroying swarms first attacked Rajasthan and then spread to Punjab, Gujarat, Maharashtra and Madhya Pradesh.

According to experts, broadly four species of locusts are found in India -- desert locust, migratory locust, Bombay locust and tree locust. The desert locust is considered the most destructive.

It multiplies very rapidly and is capable of covering 150 kilometers in a day.

This insect, a type of a grasshopper, can eat more than its body weight. A one square kilometer of locust swarm containing around 40 million locusts can in a day eat as much food as 35,000 people.

Experts blame the growing menace of desert locusts on climate change. They say breeding of locusts is directly related to soil moisture and food availability.
