TREATING CATTLE WITH INSECTICIDE - A NEW APPROACH FOR MALARIA CONTROL IN SOUTH ASIA (p 1837)
Insecticide treatment of livestock could be a new, cost-effective malaria-control strategy in south Asia, conclude authors of a study in this week's issue of THE LANCET. Indoor spraying of houses with insecticide - the standard method of malaria control in south Asia - is becoming prohibitively expensive to implement and new approaches are... view more...

Studies identify more effective treatment for malaria control during pregnancy in Africa
A review of previous studies indicates that two doses of a malaria preventive therapy during pregnancy provides substantial benefit to HIV-negative women in Africa, with more frequent dosing apparently necessary for HIV-positive women. view more (2007-06-20)

First global malaria map in decades shows reduced risk
About 35 percent of the world's population is at risk of contracting deadly malaria, but many people are at a lower risk than previously thought, raising hope that the disease could be seriously reduced or eliminated in parts of the world. view more (2008-02-26)
Whitefly spreads emerging plant viruses
A tiny whitefly is responsible for spreading a group of plant viruses that cause devastating disease on food, fiber, and ornamental crops, say plant pathologists with The American Phytopathological Society (APS). view more (2007-01-19)
In some cases, genetic resistance takes on a life of its own

Novel compounds show promise as safer, more potent insecticides
Research teams at Nihon Nohyaku Co., Ltd., Bayer CropScience and DuPont have developed two new classes of broad-spectrum insecticides that show promise as a safer and more effective way to fight pest insects that damage food crops. view more (2005-08-29)
Animal model of Parkinson's disease reveals striking sensitivity to common environmental toxins
In findings that support a relationship between agricultural chemicals and Parkinson's disease, two groups of researchers have found new evidence that loss of DJ-1, a gene known to be linked to inherited Parkinson's disease, leads to striking sensitivity to the herbicide paraquat and the insecticide rotenone. view more (2005-09-07)
Entomologists offer new hope for controlling malaria
Entomologists are bringing new hope of preventing malaria in tropical villages. Research published in the new issue of the Royal Entomological Society journal Medical & Veterinary Entomology could significantly improve the effectiveness of insecticide-treated mosquito nets. One paper (Guillet et al, Medical & Veterinary Entomology, 15(1),... view more... (2001-03-07)
Mosquito spray increases toxicity of pyrethroids in creek, study finds

Research team discovers hormone that causes malaria mosquito to urinate
Prior to coming to Nevada 16 years ago, David Schooley was a key figure at a small company in Palo Alto, Calif. that developed methoprene, an insecticide that halts the maturation of insect larvae to adults. view more (2005-08-25)
Biotech cotton provides same yield with fewer pesticides

Vaccine hope for malaria
One person dies of it every 30 seconds, it rivals HIV and tuberculosis as the world's most deadly infection and the vast majority of its victims are under five years old. view more (2007-05-24)
Researchers put the bite on mosquitoes
Few things sting like a mosquito's bite--especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well. view more (2008-01-17)
Vineyard weeds found to host Pierce's disease of grapes
New research just released in the September issue of Plant Disease suggests that weeds commonly found in California's wine country may enable the spread of Pierce's disease of grapes, one of the most destructive plant diseases affecting grapes. view more (2005-09-22)

Pesticides disrupt farmland bird food chains
Preliminary results are emerging from important new work on the indirect effects of agricultural pesticides on farmland birds in Britain. At the British Ecological Society`s Winter Meeting, at the University of Warwick on 18–20 December 2001, Tony Morris of the Royal Society for the Protection of Birds (RSPB) will present early evidence from... view more...

Most widely used organic pesticide requires help to kill
The world's most widely used organic insecticide, a plucky bacterium known as Bacillus thuringiensis or Bt for short, requires the assistance of other microbes to perform its insect-slaying work, a new study has found. view more (2006-09-26)
