Latest Desert locust Stories
The desert locust (a type of grasshopper), much like Dr Jekyll/Mr Hyde, goes from being an innocuous solitary-living individual to become a voracious gregarious animal that destroys everything on its path (and back).
A team of scientists has shown how the environment shapes learning and memory by training locusts like Pavlov's dog to associate different smells with reward or punishment.
A plague has gripped Madagascar and a UN body says the country will need $41 million over three years to help fight off an infestation that has gripped more than half of the world’s fourth-largest island.
New research has found that a protein associated with learning and memory plays an integral role in changing the behavior of locusts from that of harmless grasshoppers into swarming pests.
Scientists reported that swarming locusts not only look different and act differently to solitary locusts; they also have much larger brains.
Scientists have shown for the first time that insects, like mammals, use vision rather than touch to find footholds.
Serotonin, a chemical that moderates behavior in animals, has been shown to change the aloof desert locust into partying fiends, British researchers said. The discovery, published Friday in the journal Science, could lead to methods of inhibiting the formation of locust swarms, The New York Times reported.
Researchers have linked the radical transformation of desert locusts â€“ from harmless, solitary creatures to gregarious, swarm-forming insects â€“ to the common brain chemical serotonin.
A team of scientists led by Iain Couzin of Princeton University and including colleagues at the University of Oxford and the University of Sydney believes it may finally have an answer to this enduring mystery..."Cannibalism"
Steve Simpson explains how his basic research on the behaviour of locusts has surprising ramifications for understanding a worrying human epidemic. Locusts have the extraordinary capacity to change from harmless grasshoppers into mass swarming pests.
The Migratory Locust (Locusta migratoria), is the most widespread species of locust. It occurs throughout Africa, Asia, Australia and New Zealand. It was once very common in Europe but has now become rare there. Because of the vast geographic area it occupies, which comprises many different ecological zones, numerous subspecies have been described. However, not all experts agree on the validity of some of these subspecies. Pigmentation and size of the migratory locust vary according to its...
