Swarms have devastated crops and have caused famines and human migrations. More recently, changes in agricultural practices and better surveillance of locust breeding grounds have allowed control measures at an early stage. Traditional locust control uses insecticides from the ground or air, but newer biological control methods are proving ...
Swarms can travel 5 to 130 km or more in a day. Locust swarms can vary from less than one square kilometre to several hundred square kilometres with 40 to 80 million individuals per square kilometre. 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.
Albert's swarm was an immense concentration of the Rocky Mountain locust that swarmed the Western United States in 1875. It was named after Albert Child, a physician interested in meteorology , who calculated the size of the swarm to 198,000 square miles (510,000 km 2 ) by multiplying the swarm's estimated speed with the time it took for it to ...
Locust are historically known for wiping out fields of crops in a day. Locust have the ability to eat up to their own body weight in a single day. [ 13 ] Individuals gather in large groups called swarms, these swarms can range up to 80 million individuals that stretch 460 square miles. [ 13 ]
This is a list (alphabetized by binomial species name) of locust species of the taxonomic family Acrididae capable of density-dependent phase polyphenism and swarming behavior, potentially inflicting massive damage to crops.

Locusta migratoria migratorioides, commonly known as the African migratory locust, is a subspecies of the migratory locust family Acrididae. It occurs in most of Africa south of the Sahara Desert, but its main breeding ground, and the original source of most plagues, is on the floodplains of the Niger River in West Africa.
A bystander in Al Khobar, Saudi Arabia, captured the moment when swarms of locusts coated the sky above him on Feb. 21. According to National Geographic, locusts are sometimes solitary insects ...
