FAO released map for locust movement direction, says less likely to reach South India , Bangladesh , Nepal . So far Locust movement of Spring-bred immature adult groups and swarms that arrived in Rajasthan from the west continued to move east in the eastern portion of the state and to the central states of Madhya Pradesh and Maharashtra.
As of 26 May Locust movement, at least one swarm had reached to the northeast of Bhopal. Much of these movements were associated with strong westerly winds from Cyclone Amphan in the Bay of Bengal. Control operations are underway. Several successive waves of invasions can be expected until July in Rajasthan with eastward surges across northern India as far as Bihar and Orissa followed by westward Locust movement 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.
While in Maharastra Swarms of locusts that had entered Katol and Parseoni in Nagpur district of Maharashtra over the last four days might move towards Ramtek city though it is difficult to predict their exact flying course, a senior agriculture department official said on Wednesday. An official from Maharashtra spoke to a leading newspaper
“These swarms are moving towards Ramtek or Mouda (in Nagpur district).
However, one cannot say for sure where the swarms of locust will descend.
They might fly in the direction of Ramtek or might change the course, as they fly as per flow of wind,” Bhosale said.
Citing challenges in tracking the course of locusts, he said they get properly spotted when they descend on trees during night time.
“We have to identify possible villages where these swarms would fly to.
Our team gets information about the movement of locust through drones or social media, but many times its villagers who inform us,” he said.
Bhosale said his department is also assessing the loss caused to crops by the locust which devour on any vegetation.
