How do grasshoppers change into locusts?

In English, the term “locust” is used for grasshopper species that change morphologically and behaviourally on crowding, forming swarms that develop from bands of immature stages called hoppers. The change is referred to in the technical literature as “density-dependent phenotypic plasticity”.

This makes locusts deadly for agriculture. As they travel, they leave behind a trail of thousands of hectares of destroyed crops.

How do locust die?

Locusts in the solitary phase occupy and breed in smaller regions. The last major plague, from 1986 to 1989, hit North Africa and the Middle East. Many swarms died while crossing the Atlantic; some reached the Caribbean. Once identified, an area is sprayed with chemicals to kill locusts before they can gather.

What kills locusts naturally?

In Somalia, which has large grazing areas, FAO is instead helping the country use biopesticides. They consist of spores of the fungus Metarhizium acridum, which produces a toxin that kills only locusts and related grasshoppers.
