How Did The Desert Locust Lose Its Memory?
2014-01-14 10:59:40

Ciência Viva 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). These two very different “personas” are remarkable adaptations of a single genome to distinct environments. But apparently, this flexibility is even more impressive says Patricio Simōes, Jeremy Niven and Swidbert Ott from the Champalimaud Neuroscience...

Research Into Desert Locusts Discovers How Your Environment Shapes Your Thinking
2013-11-21 13:12:19

University of Leicester 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. Desert locusts are notorious for their devastating swarms. However, they do not always live in swarms — they switch between a lone living 'solitary phase' and a swarming 'gregarious' phase. The two phases differ profoundly in looks, behavior and in their life style. The new research from...

Satellite Imagery Helps North Africa Fight Locust Plagues

TechnologyNewsroom DMC International Imaging (DMCii) is helping The Algerian Space Agency (ASAL) to predict the spread of locust plagues across North Africa as part of a pro-active approach to tackle the destructive phenomenon using satellite imagery. Every year, North Africa is subjected to locust plagues that threaten to decimate crops and endanger countries´ food security. The satellite imagery is used to assess vegetation conditions, which helps to predict the locations of...

Locust Plague Devouring Madagascar, $41M Needed To Combat Infestation
2013-03-28 08:11:51

Lawrence LeBlond for redOrbit.com - Your Universe Online A plague has gripped Madagascar and a UN body says the country will need $41 million over three years to help fight off the infestation that has gripped more than half of the world´s fourth-largest island. The plague comes in the form of locusts, a term generally referring to the swarming phase of several species of short-horned grasshoppers. This plague has been increasingly threatening Madagascar´s crop production and...

WASHINGTON, July 20, 2012 /PRNewswire-USNewswire/ -- Following is the daily "Profile America" feature from the U.S. Census Bureau: (Logo: http://photos.prnewswire.com/prnh/20110428/DC91889LOGO) FRIDAY, JULY 20: HISTORIC BUG PROBLEM Profile America -- Friday, July 20th. Beginning on this date in 1874, the largest swarm of Rocky Mountain locusts ever recorded blackened the skies from the Dakotas to Texas and stripped farm fields in minutes. The swarm is estimated to have been 1,800 miles...

Low protein grasses, land management choices can make insect swarms likely to roam While residents of the United States and much of Europe think of locust plagues as biblical references, locust swarms still have devastating effects on agriculture today, especially in developing countries in Asia and Africa. In a study in the journal Science on Jan. 27, scientists from Arizona State University and the Chinese Academy of Sciences show that insect nutrition and agricultural land management...

New Insight Into Why Locusts Swarm
2011-12-20 10:33:36

Protein associated with learning implicated in causing grasshoppers to swarm 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. Desert Locusts are a species of grasshopper that have evolved a Jekyll-and-Hyde disposition to survive in their harsh environment. In their solitary phase, they avoid other locusts and occur in very low density. When the...

Literature and films have left us with vivid images of the grasshopper plagues that devastated the Great Plains in the 1870s. Although commonly referred to as grasshoppers, the infestations were actually by Rocky Mountain locusts. The Rocky Mountain locust became extinct in 1902, but their cousins, grasshoppers and Mormon crickets, today still cause an estimated $1.5 billion (2005 U.S. dollars) in damage to grazing lands in the American West. A long-running research project directed by...

Scientists reported that swarming locusts not only look different and act differently to solitary locusts; they also have much larger brains. Scientists at the University of Cambridge captured images of the results of dramatic changes inside the insects' heads. The team said the same locust could switch between a "solitary" and swarming phase. They reported their findings in Proceedings of the Royal Society B. "Normally locusts would avoid close contact with each other," Dr Swidbert Ott...

Farmers in eastern Australia are battling a plague of locusts, which have infested a 190,000 square mile stretch from central Queensland all the way south to the capital of Melbourne. "What we've got certainly is a very large and widespread infestation," Australian Plague Locust Commission (APLC) chief Chris Adriaansen told AFP reporters on Wednesday. "It's simply a reflection of the fact that we've had widespread rain across that entire area." According to Adriaansen, things have gotten so...

Red Locust, Nomadacris septemfasciata
2013-07-10 15:41:21

The red locust (Nomadacris septemfasciata) is a species of grasshopper that is native to Sub-Saharan Africa, where it prefers to swarm moist areas like seasonal floodplains. It can be found in areas with grain, its main food source, and areas with some tree cover. Adults are typically brownish-tan in color and can reach an average body length between 2.4 and 3.3 inches depending upon the sex, with females growing larger. Young individuals of this species can vary in color depending upon which...

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...
