After searching for 50 years, scientists finally have discovered new mosquito repellents that beat DEET for warding off those pesky, disease-carrying insects. The stuff seems like a dream come true. It makes mosquitoes buzz off three times longer than DEET, the active ingredient in many of today's bug repellents. It does not have the unpleasant odor and it does not cause DEET's sticky-skin sensation. But there's a fly in the ointment. The odds are against any of the new repellents finding a...

U.S. scientists say they've created new mosquito repellents that perform better than DEET, the most used chemical to repel the disease-carrying insects. U.S. Department of Agriculture researchers said their new repellents work three times longer than DEET, eliminates DEET's unpleasant odor and don't cause DEET's sticky-skin sensation. But scientists caution the new repellents might never find a place on store shelves. Ulrich Bernier, the USDA's lead researcher for the repellent study, said...

After searching for more than 50 years, scientists finally have discovered a number of new mosquito repellents that beat DEET, the gold standard for warding off those pesky, sometimes disease-carrying insects. The stuff seems like a dream come true. It makes mosquitoes buzz off three times longer than DEET, the active ingredient in many of today's bug repellents. It does not have the unpleasant odor of DEET. And it does not cause DEET's sticky-skin sensation. But there's a fly in the...

HARRISBURG, Pa., Aug. 11 /PRNewswire-USNewswire/ -- State Health Secretary Everette James today reported this year's first confirmed human case of West Nile virus in Pennsylvania. The individual is a 21-year-old woman from Luzerne County. "The number of cases of West Nile disease has declined significantly in the past five years but this season's first case is a reminder that the disease is still out there," Secretary James said. "You can take precautions to protect yourself from this...

The active ingredient in many insect repellents, N,N-Diethyl-3-methylbenzamide, known as DEET, may harm the central nervous system, French researchers said. Vincent Corbel from the Institut de Recherche pour le Developpement in Montpellier and Bruno Lapied of the University of Angers, both in France, led a team of researchers that investigated the toxicity of DEET. We've found that DEET is not simply a behavior-modifying chemical but also inhibits the activity of a key central nervous...

A study released on Wednesday warned that one of the world's most common insect repellents acts on the central nervous system in the same way as some insecticides and nerve gases, AFP reported. Researchers say moderate use of the chemical compound deet is most likely safe, but experiments on insects, as well as on enzymes extracted from mice and human neurons, showed for the first time that it can interfere with the proper functioning of the nervous system. Many experts are urgently calling...

DEET, the active ingredient in many insect repellents, has been found to be neurotoxic in insects and mammals, French researchers reported Tuesday. Because of their finding, researchers are saying more investigations are needed quickly to either confirm or dismiss potential neurotoxicity to humans, the researchers said in a news release. We've found that DEET is not simply a behavior-modifying chemical but also inhibits the activity of a key central nervous system enzyme, acetycholinesterase,...

Experts say more than half of the states in the U.S. now have mosquitoes that are known to spread dengue fever. A new report by the Natural Resources Defense Council showed that two types of mosquitoes capable of transmitting the dengue fever virus are invading Southern and Mid-Atlantic states, creating conditions more favorable for an outbreak. An estimated 173 million Americans live in counties that now contain one or both of the mosquito species, a problem that could escalate with global...

WINNIPEG, Canada, June 30 /PRNewswire/ -- Every summer, the bloodsuckers send Canadians swatting and running for cover. And for good reason. More than just creatures with an annoying buzz, mosquitoes inflict bites that hurt, itch and cause human flesh to swell and redden. An even more serious consequence of the mosquito bite: West Nile Virus. While many Canadians warily use conventional bug repellents--ones with harsh and controversial chemicals that can sting eyes and irritate...

BALTIMORE, June 16 /PRNewswire/ -- The 2009 monsoon season will soon arrive in the Asian territories and culicine mosquito populations are expected to increase. "These mosquitoes may carry the virus that causes Japanese Encephalitis (JE), which kills 10-15,000 people each year," warned Fran Lessans, CEO of Passport Health, the largest provider of travel medical services in the U.S. A new vaccine called Ixiaro(R) has been approved by the FDA, and is ready for distribution in the United States....
