How common are locust plagues?

Locusts occur in many parts of the world, but today locusts are most destructive in subsistence farming regions of Africa.

Now, of the ten plagues, the eighth one was that of locusts. Moses warned the Pharaoh that God will send so many locusts that they will “cover each and every tree of the land and eat all that is there to be eaten”. Every time the Pharaoh refused, a fresh plague was inflicted upon his kingdom.

What do locusts?

Locust Diets Large swarms of locusts can completely strip the foliage and stems of plants such as forbs and grasses. Some species consume a variety of plants, while others have a more specific diet. They often eat dry plant matter on the ground and will forage for weak or dead grasshoppers when plant food is scarce.

Are Locusts dangerous?

Locusts aren’t very dangerous when solitary or in small groups, but their behaviour changes when they transform from ‘solitary phase’ into ‘gregarious phase’, and start forming ‘swarms’. … A one-km swarm with about 40 million locusts can consume what 35,000 people do in a day.

What is causing locust swarms?

When desert locusts meet, their nervous systems release serotonin, which causes them to become mutually attracted, a prerequisite for swarming. The initial bands of gregarious hoppers are known as “outbreaks”, and when these join together into larger groups, the event is known as an “upsurge”.

Now crops can be sprayed with insecticides from vehicles or aeroplanes. Scientists are trying to improve the control of locusts, by preventing or dispersing swarms. Farmers and scientists also link to try to predict when a swarm will appear, so that controls can be introduced earlier.

The wet conditions have persisted, creating ideal bug breeding conditions. Once they enter the gregarious phase, a generation of locusts can multiply twentyfold every three months.

How a single locust becomes a plague?
