New Delhi: As per the locust status Bulletin of 27th May, 2020 in Pakistan and Iran by Food and Agriculture Organization (FAO), adult locusts are forming groups and small swarms in spring breeding areas in Baluchistan, Indus Valley (Pakistan) and southern coast and parts of Sistan-Baluchistan. These infestations will move to the summer breeding areas along the Indo-Pakistan from Cholistan to Tharparkar.

In India, Spring-bred immature adult groups and swarms continued to move east and to the central states of Madhya Pradesh and Maharashtra. Much of these movements have been associated with strong westerly winds from Cyclone Amphan.

Several successive waves of invasions can be expected until July, 2020 in Rajasthan with eastward surges across northern India as far as Bihar and Orissa followed by westward movements and a return to Rajasthan on the changing winds associated with the monsoon. These movements will cease as swarms begin to breed and become less mobile. Swarms are less likely to reach south India, Nepal, and Bangladesh.
