Fly model previously used to pinpoint genetic variance in toxicity of chemotherapeutic agent As Rachel Carson predicted 50 years ago in her groundbreaking book Silent Spring, crop pests are capable of outwitting the chemical compounds known as xenobiotics that are devised to kill them. This development of resistance to insecticides is a serious problem because it threatens crop production and thereby can influence the availability and costs of many foods as well as the economy. To...

Study Finds Market Forces Influence The Value Of Bat-provided Services
2014-02-04 10:21:10

University of Tennessee at Knoxville Services provided by Mother Nature, such as pest control from insect-eating bats, are affected by market forces like most anything else in the economy, a University of Tennessee, Knoxville, study finds. The study's results have implications for biodiversity conservation efforts. Researchers from UT and the University of Arizona, Tucson, studied how forces such as volatile market conditions and technological substitutes affect the value of pest...

Corn that contains proteins that protect it from insect damage has been grown in the U.S. since the mid-1990s. Known as Bt corn, because the proteins are derived from a bacterium called Bacillus thuringiensis, these plants have been widely grown by farmers. While Bt corn has been highly effective against the European corn borer, it has been less so against the western corn rootworm, which has been documented to show resistance to the Bt proteins. In a new article in the Journal of...

Secret Of Cattle Ticks' Resistance To Pesticide Unlocked
2013-10-07 14:17:27

University of Glasgow Scientists have discovered how a tick which transmits devastating diseases to cattle has developed resistance to one of the main pesticides used to kill it. Approximately 80% of cattle around the world, mostly in the tropics and sub-tropics, are exposed to the cattle tick – Rhipicephalis microplus – which can cause anaemia, reduced rate of growth and death, resulting in a major economic impact on farmers. Prevention of disease is through frequent treatment...

Evolution Fights Back Bioengineered Crops

April Flowers for redOrbit.com - Your Universe Online Since 1996, farmers across the globe have planted more than a billion acres of genetically modified corn and cotton that have been engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis, or Bt for short. Organic farmers used Bt proteins in sprays for decades to kill a number of devastating pests because the proteins are considered environmentally friendly and harmless to humans. Some scientists, however,...

Pyramid Strategy For Biotech Crops Not A Silver Bullet
2013-03-31 06:12:50

Brett Smith for redOrbit.com - Your Universe Online Genetically engineered crops that are designed to be pest resistant may not be as effective as previously thought, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). First grown in 1996, the pest-resistant plants produce toxins from the bacterium Bacillus thuringiensis, or Bt for short. Deemed safe for human consumption, Bt crops increase yields and reduce the need for pesticides that can damage the...

On Contact Solutions (OnContactSolutions.com), a supplier of green products to the hospitality industry, now warrants the efficacy of Cimi Shield, a revolutionary soybean extract spray that is non-toxic, kills Bed Bugs on contact and prevents Bed Bug infestations for one year. When appropriately applied, Cimi-Shield is guaranteed to prevent future infestations by leaving a residual that lasts for 12 months, destroying the bugs that hatch or arrive after treatment. Miami, FL (PRWEB) March 19,...

What do cancer cells, weeds, and pathogens have in common? They all evolve resistance to the treatments that are supposed to eliminate them. However, researchers developing the next generation of antibiotics, herbicides, and anti-cancer therapeutics rarely come together to explore the common evolutionary principles at work across their different biological systems. The new American Academy of Microbiology report "Moving Targets: Fighting Resistance in Infections, Pests, and Cancer" concludes...

A new discovery promises to allow expanded use of a mainstay biological pest control method, which avoids the health, environmental and pest-resistance concerns of traditional insecticides, scientists are reporting. The advance toward broadening applicability of the so-called sterile insect technique (SIT) appears in the journal ACS Synthetic Biology. Luke Alphey and colleagues explain that the Lepidoptera, a large family of insects with a caterpillar stage, cause widespread damage...
