Locusts Attack in India: Large swarms of Desert Locusts have entered India's Rajasthan through Pakistan in search of crops and greenery to satisfy their hunger. The locusts swarms began from Iran in 2019, migrating to Pakistan and now have entered India in Rajasthan, Punjab, Gujarat and Madhya Pradesh. These desert locusts have already infested areas of North & Central India and are slowly moving towards Uttar Pradesh, Delhi and Maharashtra.
While India is already battling the consequences of novel Coronavirus on its economy, locust attack or plague could further devastate its agricultural economy and risk India's food security. This is the worst ever locusts attack in last three decades. The Locust Warning Organisation has suggested for the use of drones for sprinkling chemicals in Rajasthan to kill the locust.
