(Beyond Pesticides, July 27, 2012) A Connecticut state Department of Energy and Environmental Protection study has detected residues of mosquito control pesticides in lobsters pulled from Long Island Sound. Using new testing technology that can detect small concentrations of substances, ten lobsters were tested for three common mosquito control chemicals: malathion, methoprene, and resmethrin. Positive results were found in the organ tissue of one lobster for methoprene and three lobsters for resmethrin. The results present the first scientific evidence that pesticides may be affecting lobsters in the Sound and are likely to further anger the Connecticut lobstering industry which, for years, has been pointing to mosquito pesticides as a likely cause of a serious decline in the lobster population of the Sound, but has been met with resistance. Late summer declines in the Sound’s lobster population have been alarmingly common throughout much of the last decade, devastating fishers and the local economy that depends on them. A number of factors have been blamed, but the lobstering community has increasingly been pointing to mosquito pesticides for several reasons. Some, such as methoprene, have a tendency to sink to the bottom of the ocean water, where lobsters live and feed. Additionally, lobsters […]

(Beyond Pesticides, July 24, 2012) This past weekend, the State of Massachusetts undertook what is thought to be its largest aerial spraying of pesticides covering nearly 400,000 acres and 21 communities. By using the pretext of a new emergency, the state improperly evaded Clean Water Act protections according to Public Employees for Environmental Responsibility (PEER). PEER has asked for a federal investigation. The massive spraying was triggered by the trapping of mammal-biting mosquitos which tested positive for Eastern Equine Encephalitis (EEE) on July 9th. On July 17th, the state Department of Public Health declared a pest emergency to justify aerial spraying over Bristol and Plymouth Counties through September 30, 2012. The spraying took place July 20th, 21st, and 22nd. Typically, aerial spraying of pesticides requires a federal pollution discharge permit but the permit may be dispensed with if the application is done “less than ten days after identification of the need for pest control” — a requirement violated in this case. In addition, PEER charges that the state knew it would conduct aerial spraying in this area for months and is inappropriately using an emergency declaration to avoid the need for a permit. The permit is not merely red tape, […]

(Beyond Pesticides, June 27, 2012) One county in New Jersey is getting serious about combating mosquitoes this season. Instead of relying on pesticide spraying, which has been shown to not be effective, the Cape May County Department of Mosquito Control is employing 10,000 tiny shrimp-like crustaceans that will eat their way through mosquito larvae in the county’s swamps, roadside ditches and small pools. The latest weapon in the battle against mosquitoes is barely visible. The crustaceans, known as copepods, are cousins to crayfish and water fleas, and do not get much bigger than two millimeters. They are voracious predators of mosquito larvae. New Jersey recently delivered 10,000 of the tiny shrimp-like crustaceans to Cape May County. They are already being used to fight mosquitoes in Bergen, Passaic, and Morris counties. Ocean County is next on the delivery list and six other counties will follow. “The days of driving a truck down the street and spraying pesticides are long gone. These copepods can pick up where fish leave off,” according to Administrator Robert Kent, of the state Office of Mosquito Control. Natural Predators as a Solution for Mosquito Control New Jersey has used mosquitofish, fathead minnows, killifish, bluegill and other fish […]

(Beyond Pesticides, June 14, 2012) Across the U.S., some communities are responding to the threat of mosquito-transmitted West Nile virus (WNv) with aerial insecticide spray programs. This method of mosquito management is widely considered by experts to be both ineffective and harmful due to the hazards associated with widespread pesticide exposure. Given the lack of evidence that adulticides (insecticides that target adult mosquitoes) reduce or prevent mosquito-borne incidents or illnesses, public health and environmental advocates question the decision to resort to indiscriminate spraying. Studies have shown that aerial spraying for adult mosquitoes is greatly ineffective (as little as 1% of mosquitoes will be hit, according to Cornell University entomologist David Pimentel). Pesticides like those typically used in aerial sprayings against mosquitoes, including synthetic pyrethroids and organophosphates, have been linked to numerous adverse health effects including asthma and respiratory problems, dermatological reactions, endocrine disruption, chemical sensitivities, and cancer. These chemicals can also be harmful or fatal to non-target wildlife, including pollinators like the honeybee. Further, pesticides that kill mosquitoes also kill their predators, leading to fewer biological checks on mosquito populations than without spraying. Here are some of the areas currently, or soon to be spraying insecticides intended to kill adult […]

(Beyond Pesticides, May 22, 2012) The Spanish-based Inesfly company announced recently its plans to release commercially pesticide encapsulated paint, Inesfly 5A IGR, containing two neurotoxic organophosphates (OPs), chlorpyrifos and diazinon, and the insect growth regulator (IGR), pyriproxyfen, which it hopes will combat malaria in sub-Saharan Africa. The company’s owner Pilar Mateo, PhD, calls her product “a vaccine for houses and buildings” and explains that because the insecticides are released slowly from the paint, it remains effective for two to four years. This formulation of Dr. Mateo’s paint could not be registered for use in the U.S. because both indoor residential uses of chlorpyrifos and diazinon have been banned because of risks posed to children’s health, although the company has another formulation that substitutes pyrethroids for the organophosphates. Though probably well-intentioned —Dr. Mateo has already invested $6 million of her family’s money and $12 million in grants from nonprofits, on research, creating educational programs about hygiene, and donating paint to more than 8,000 homes in Latin America and Africa””the product puts the people it is supposed to protect from disease at risk for other health problems. Organophosphate insecticides have been linked to a host of neurodevelopmental problems, especially in children. Because […]

(Beyond Pesticides, February 15, 2012) California mosquito control agencies are charging that new NPDES permitting regulations would eliminate West Nile virus fogging and jeopardize public health. In response, the state of California has proposed to scale-back pesticide regulations, easing rules on fumigating adult mosquitoes. This is in spite of the high risk for further degradation of already contaminated surface waters in the state, and contrary to the stipulations and protections set out in the Clean Water Act. The current federal National Pollutant Discharge Elimination System (NPDES) permit, which recently went into effect after much resistance from the pesticide and agriculture industry and intensive lobbying efforts in Congress, does not authorize the discharge of biological and residual pesticides or their degradation by-products to waters of the U.S. that are impaired by the same pesticide active ingredients or any pesticide in the same chemical family. ”˜Impaired waters’ are polluted waters, i.e. those waters not meeting water quality standards pursuant to section 303(d) of the Clean Water Act (CWA). The NPDES permit is authorized under the CWA to require pesticide applicators to apply for permits before applying pesticides on or near surface waters. This process involves keeping records of pesticides used and monitoring […]

(Beyond Pesticides, October 7, 2011) Commercial lobster fishers operating in Long Island Sound off the coast of Connecticut have begun to suspect that the mosquito killing chemical methoprene, sprayed by neighboring New York State as part of its West Nile virus (WNv) control program, is contributing to widespread deaths of lobsters in the sound. Believing that a large amount of the chemical flowed into the sound in late summer due to heavy rains from Hurricane Irene, the lobster fishers are asking New York to follow Connecticut’s example and switch its WNv control method to the less toxic bacillus thuringiensis. Late summer declines in the sound’s lobster population have been alarmingly common throughout much of the last decade, devastating fishers and the local economy that depends on them. A number of factors have been blamed, but the lobstering community has increasingly been pointing to mosquito pesticides for several reasons. Methoprene has a tendency to sink to the bottom of the ocean water, where lobsters live and feed. Additionally, lobsters are a distant cousin of mosquitoes, and the methoprene acts on them in much the same way that it does the insects. Finally, the western part of the sound was the hardest […]

(Beyond Pesticides, September 10, 2010) The Department of Health (DOH) of the Republic of the Philippines recently launched a strategy against Dengue Fever, favoring integrated pest management (IPM) strategies over pesticide sprays. The campaign, called D.E.N.G.U.E. stands for D – daily monitoring of patient’s status, E – encourage intake of oral fluids like oresol, water, juices, etc, N — note any dengue warning signs like persistent vomiting and bleeding, G — give paracetamol for fever and NOT aspirin, because aspirin induces bleeding, U — use mosquito nets and E — early consultation is advised for any warning signs. Health Secretary Enrique Ona also reiterated that the most effective way to prevent and fight dengue is still by practicing the DOH’s ”˜4-S’ strategy consisting of Search and destroy, Self-protective measures, Seek early treatment and Say no to indiscriminate fogging. The new D.E.N.G.U.E. strategy has been devised by the DOH to educate the public on home treatment of mild dengue cases. This is to also help decongest hospitals by giving an assurance that not all dengue cases require hospital confinement but can be managed at home using the strategy. Secretary Ona is educating the public that many dengue cases, if mild, can […]

(Beyond Pesticides, May 13, 2010) Recent tests find that mosquitoes that are insensitive to DEET, the pesticide commonly used to repel the pesky flying insect, can pass this characteristic as a genetic trait onto their offspring. The findings are published in the May 3 edition of the journal Proceedings of the National Academy of Sciences. In order to hunt for blood, female mosquitoes use their antenna to locate humans; however, according to researchers, DEET temporarily destroys an insect’s sense of smell by hindering the function of certain odor receptors. The researchers observed which insects bit DEET-treated human arms and discovered that a gene alteration prohibited a sensory cell on the bugs’ antennae from detecting the chemical. “There is something in the antenna they use to smell that reacted differently,” Dr. Nina Stanczyk of Rothhamstead Research, an agricultural research center in the U.K., told the Toronto Star. Scientists studied one species of DEET-insensitive mosquitoes, the Aedes aegypti, a species that carry the diseases yellow fever and dengue fever. When mutated females were bred with males of unknown sensitivity in tests, the quantity of mosquitoes that were insensitive to DEET rose from 13 to 50 percent in one generation. Though scientists are […]
