Scientists discuss improved biopesticides for locust control in West Africa

Two Virginia Tech scientists contributed by invitation to an international scientific meeting called by Abdoulaye Wade, president of Senegal, to identify strategies for the control of the ongoing locust outbreak in West Africa. Last year, locusts stripped fields of crops and trees of foliage across several countries, causing severe income and food supply loss. Larry Vaughan, associate pro...

Six million Africans face famine because of locusts, drought

With locusts and drought having destroyed crops and stripped grazing land for six million people across West Africa, small farmers have started selling livestock cheaply and eating the seed corn they should plant during next month's expected rains, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said today. "The combined effect of drought and locust attack, pa...

UN successfully tests 'green' pesticide against locusts

A new method for manipulating macromolecules has been developed by researchers at the University of Illinois at Urbana-Champaign. The technique uses double-stranded DNA to direct the behavior of other molecules. In previous DNA nanotechnology efforts, duplex DNA has been used as a static lattice to construct geometrical objects in three dimensions. Instead of manipulating DNA alone into s...

Locusts' built-in 'surface analysis' ability directs them to fly overland

Swarms of millions of locusts have, since Biblical times and until our very own day, been considered a "plague" of major proportions, with the creatures destroying every growing thing in their path. Until now, it was thought that the directions of these swarms were predominantly directed by prevailing winds. Now, Hebrew University of Jerusalem scientists have shown that a physiological tra...

Ancient trans-Atlantic swarm brought locusts to the New World

Somewhere between three and five million years ago, a massive swarm of locusts took off from the west coast of Africa and made an unlikely voyage across the Atlantic Ocean to colonize the New World, says an international team of researchers. Using genetic evidence from more than 20 species of locusts, scientists from the Universities of Toronto, Arizona, Maryland, Cornell University and th...
