    pesticides are often effective in controlling mosquito larvae before they hatch repeated use of these pesticides has raised serious environmental and health concerns Aedes aegyti feeding This mosquito is one of the most important vectors of arbovirus infections especially dengue and yellow fever throughout the tropics Photo courtesy Wellcome Trust DEET is a chemical N N diethyl meta toluamide used as the active ingredient in many insect repellent products First developed by the U S Army in 1946 it is now widely used around the world but may have toxic effects Some persons who used products containing a high concentration such as 50 or 75 percent of DEET or who were exposed to excessive amounts of DEET experienced rashes blisters and skin and mucous membrane irritation In a few cases of overdose and misuse brain effects encephalopathy and seizures occurred in children says the U S Agency for Toxic Substances and Disease Registry A recent study by Duke University pharmacologist Mohamed Abou Donia details a list of neurological harms caused by DEET and other conventional insecticides from memory loss to tremors to slurred speech The study also found DEET caused brain cell death and severe behavioral changes in rats These problems have highlighted the need for new strategies for mosquito larval control says Chang adding that scientists are increasingly turning to more benign natural chemicals to ward off mosquitoes and other pests Larvicidal activity is judged with a measurement called LC50 The LC50 value is the concentration that kills 50 percent of mosquito larvae in 24 hours Chang explains Lower LC50 translates into higher activity because it takes a lower concentration to kill larvae in the same amount of time All four compounds had LC50 values of less than 50 parts per million ppm with cinnamaldehyde showing the strongest activity

    the pesticide free foothills Guillette had the children draw stick figures at various developmental stages The organic kids drawings are round sloppy but robustly human looking The children of pesticide farmers drew figures that looked eerily unfinished and disjointed There was a street fair at 118th Street selling produce the day of the Beyond Pesticides Conference at Riverside Church in Manhattan A nice little irony considering that the conference opened with a real time video of spray trucks cruising the Bronx trailing plumes of Anvil that enveloped sidewalks including the produce stands that line New York s city streets The footage captured by videographer Roy Doremus showed people choking and holding up their collars to their mouths as the truck passed by This is when you might start to think twice not only about your own body but the apple that John Stossel said was safe any produce found with traces of Sumithrin Anvil 10 10 s active ingredient could be subject to sanctions such as seizure or injunction by the FDA said city Assembly member Scott Stringer when he saw the tape Yet there is no law on the books that says officials must notify sidewalk stands like these or even sound a warning telling people to get off the streets during spraying It would be a totally different scenario if they would do this at 3 4 in the morning said Doremus Yet the spraying started before midnight on a balmy August Friday night The conference closed with a speech by the event s big draw presidential candidate Ralph Nader Consumer advocate Nader was a little late getting to the podium that Saturday night Riverside Church was filled with Greens One red haired Nader supporter pushed her way to the third pew wearing a T shirt that read Bush and Gore make me wanna Ralph A woman across from her whispered I m just here to see Ralph A woman in front of them both who had been knitting a potholder the entire four hours of the conference responded I m here to ask him where he was last year when they sprayed Malathion Nader s sermon was a little groggy a little hit and miss for the feature speaker at a pesticides conference but coherently in line with the consumer advocacy slant he s pushed for 35 years Corporate science pervades the whole area of evaluation of technology on health and safety he said It s driven by the political power of the Monsanto or the DuPont It demands confidentiality And it s driven overwhelmingly by the profit message The conclusion It is a rather lethal combination Nader said when you combine the political power of these companies to get their ways in Washington with the profit driven motive the whole process is rigged in favor of more and more chemical application The public is also an indispensable pawn in reinforcing the corporate profit loop In facing pesticide spraying there is a certain resignation that affects a

  • Attached is a good article from Newsday about the efficacy of WNV mosquito spraying
    lethal virus is transmitted In the absence of stronger evidence advocates of spraying argue that the relatively low rate of severe human illness this year there have been no deaths in New York State in 2000 from West Nile and just seven last year demonstrates that insecticides along with public education and efforts to eliminate mosquito breeding sites is keeping most people safe even as the virus spreads geographically We ve always said there s no way we could break the transmission cycle in nature and stop this virus from spreading without doing a lot more spraying than would be acceptable to the public said Dr Stephen Ostroff a senior CDC official who is coordinating a nationwide effort to control the virus So our perspective on the use of pesticides is that we re trying to reduce the risk of illness to humans and there s no question that we ve succeeded One could argue that the number of human cases would have been low anyway even without spraying We ll never know the answer to that and I don t necessarily want to know because I m not going to recommend that local communities put people at risk by not using all of the appropriate control measures Critics and supporters of insecticide spraying agree on one thing It s not the most efficient way to control mosquitoes Studies have consistently shown that on average less than one tenth of 1 percent of the millions of droplets released from a helicopter or plane during a typical spraying run actually hits a mosquito according to Cornell s Pimentel who believes spraying is nonetheless justifiable in some circumstances In addition he said if there are numerous trees buildings or other obstructions in the area the spray cloud will almost certainly miss large areas of the target zone including mosquitoes inside buildings For those reasons and others the consensus among experts is that educating the public about how to avoid being bitten eliminating breeding sites and killing larval mosquitoes with less toxic sprays before they take wing are all more efficient than trying to kill adult mosquitoes with pesticides But health officials in New York City Nassau Suffolk and other local governments around the region said even though they emphasized preventative measures this spring by midsummer their surveillance efforts were showing that many mosquitoes and birds around the region were infected often in densely populated areas At that point they said spraying was the best control option left The debate over whether they made the right choice is especially complicated because it s so difficult to measure or even define a successful pesticide application It s just not a straightforward thing to measure the efficacy of a large spray because weather and other conditions can vary so much from place to place and from hour to hour said Dominick Ninivaggi who heads the mosquito control program in Suffolk County the most extensive in New York State Local health officials say they have undertaken
