Locust swarms had infested 23 countries by April 2020. East Africa was the epicenter of the locust crisis—with Ethiopia, Kenya, Somalia, and Uganda among the affected countries. However, the locusts had traveled far, wiping out crops in Pakistan and damaging farms in Yemen, a fragile country already hit hard by years of conflict.
Early intervention to prevent large locust swarms is more successful than later action once swarms have built up. The means to control locust populations is now available, but organisational, financial, and political problems may be difficult to overcome. Monitoring is the key to early detection and eradication.
As locusts are a form of grasshopper that appear when grasshopper populations reach high densities, it was theorized that M. spretus might not be extinct, that "solitary phase" individuals of a migratory grasshopper might be able to turn into the Rocky Mountain locust given the right environmental conditions; however, breeding experiments using ...
The desert locust is a species of orthopteran in the family Acrididae, subfamily Cyrtacanthacridinae. [2] There are two subspecies, one called Schistocerca gregaria gregaria, the better known and of huge economic importance, located north of the equator, and the other, Schistocerca gregaria flaviventris, [9] [10] which has a smaller range in south-west Africa and is of less economic importance ...

In such circumstances, locusts increased very rapidly. By early 2004, the threat materialized as swarms of locusts started to form and move north into important agricultural areas in Morocco and Algeria, inflicting damage to crops.

Man, Toyota (NYS: TM) can't catch a break. Flooding in Thailand, a major manufacturing hub for several Japanese automakers, has led to new shortages of critical parts for both Toyota and rival ...
An adult locust can consume its own weight (several grams) in fresh food per day. For every million locusts, one ton of food is eaten. In Africa, the last serious widespread plague of L. m. migratorioides occurred from 1928 to 1942. Since then, environmental transformations have made the development of swarms from the African migratory locust ...
