The Delhi Forest Department is also considering covering the saplings in its nurseries with polythene to protect them against the attack.

The Delhi government has asked the concerned authorities to spray insecticides and pesticides on standing crops, vegetation, gardens and orchards to prevent a probable attack of desert locusts in Delhi.

In an advisory issued on Wednesday, Agriculture Department Joint Director AP Saini asked authorities to organise awareness programmes for the public and farmers to prevent the attack of locusts.

"As the swarm of locusts flies in daytime and rests during the night, it should not be allowed to rest at night," it said, asking authorities to carry out spraying of pesticides chlorpyrifos and malathion.

The Delhi Forest Department is also considering covering the saplings in its nurseries with polythene to protect them against the attack.

"It is not possible to cover the trees. We will at least cover the saplings in the nurseries," said Principal Chief Conservator of Forests Ishwar Singh. "Covering plants with polythene can also be counter-productive during this heat. So, we will do this only when we know for sure that the swarm of locusts is headed towards Delhi."

Singh said that in a city like Delhi, spraying of chemicals can be detrimental for environment.

"If we spray the vegetation, trees and plants with chemical in anticipation of a locust attack, we should also consider how dangerous it will be for the environment," he said, adding there are 14 lakh saplings in 14 government nurseries across Delhi.

India is battling the worst desert locust outbreak in recent times. The crop-destroying swarms first attacked Rajasthan and have now spread to Punjab, Gujarat, Maharashtra and Madhya Pradesh.

Experts say 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 kilometres in a day.

This insect, a type of a grasshopper, can eat more than its body weight. A one square kilometre 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.
