description Locusta migratoria Overview
Locusta migratoria, commonly known as the migratory locust, is a grasshopper belonging to the Acrididae family. It’s notable for its capacity to form massive swarms, posing significant agricultural threats across Africa, Asia, and Australia. These swarms have been recorded for millennia, impacting human populations and food security. The species belongs to the Gomphocerinae subfamily and is particularly prevalent in the Palearctic region.
Researchers and agricultural professionals studying pest management and swarm behavior utilize this locust as a key subject of study.
help Locusta migratoria FAQ
What is the geographical range of the Locusta migratoria?
The Locusta migratoria, or migratory locust, has an incredibly vast geographical range that spans across Africa, Asia, and Australia. It is the most widely distributed locust species in the world. Different subspecies have adapted to these varied continents.
How does Locusta migratoria affect Australian agriculture?
In Australia, the Australian plague locust, a relative of Locusta migratoria, periodically forms massive swarms that cause severe agricultural damage. Locusta migratoria itself is more prominent in Africa and Asia, but the family's swarming behavior poses a consistent threat globally. They can consume massive amounts of crops and vegetation.
What is the difference between solitary and gregarious phases of Locusta migratoria?
In its solitary phase, Locusta migratoria behaves like a typical harmless grasshopper, but under crowded conditions, it shifts to a gregarious phase. In this swarming phase, they change color, become highly social, and form massive plagues. This transformation is an evolutionary adaptation to limited resources.
How long have Locusta migratoria swarms been documented?
Swarms of Locusta migratoria have been recorded for millennia, with historical accounts appearing in ancient texts. They have been a persistent agricultural threat to human civilizations throughout recorded history. Their swarms are among the oldest known natural disasters.
