(Beyond Pesticides, July 27, 2016) In South America, Colombia has officially declared an end to its Zika epidemic. The country, which previously had the highest cases of suspected Zika virus infection after Brazil, with a total of more than 99,721 people infected since September 2015 have registered a drop in the number of infections to 600 new cases a week, down significantly from a peak of more than 6,000 cases a week in February, according to health officials. Fernando Ruíz, M.D., Deputy Minister of Health and Service Provision in Colombia, said the numbers signaled that the epidemic had given way to an endemic phase of the disease, in which it continues to be present but spreads much more slowly. This news arrives following the publication of Zika Virus Disease in Colombia —Preliminary Report, which suggests that infe ctions late in pregnancy may pose less risk to the fetus than widely feared. The report follows thousands of women in Colombia who have had symptoms consistent with Zika virus disease during pregnancy to try to better understand the risk the virus poses. At the time of the report, the country had only seven official cases of microcephaly, a birth defect marked by […]

(Beyond Pesticides, July 26, 2016)  Health Canada’s Pest Management Regulatory Agency (PMRA) announced this week it will cancel certain  formulations  of boric acid-based pesticides. The announcement reflects the latest science showing that certain products, such as those in dust formulations or open baits, put residents at inhalation and ingestion exposure risk, respectively, to the naturally occurring element  boron and borate compounds. PRMA’s decision  is part of the Health Canada’s registration review of boric acid, which, like that of the U.S. Environmental Protection Agency (EPA), is conducted every 15 years. PRMA is cancelling the following uses of boric acid and similar compounds All domestic dust formulation products All domestic granular formulation products Domestic solution formulation products, with the exception of enclosed bait stations and spot treatment with gel formulations For other uses, PRMA has amended label requirements to better protect handlers and users of the pesticide. For example, the agency will update label directions to specify that boron products can only be applied to areas inaccessible to children and pets. Jane Philpott, Minister of Health in Canada said in a press release, “even natural ingredients like boric acid can pose a risk to Canadians. That’s why Health Canada looks at all […]

(Beyond Pesticides, July 11, 2016) The Centers for Disease Control and Prevention (CDC) and the U.S. Environmental Protection Agency (EPA) announced last Wednesday, July 6 that Zika is spreading rapidly in Puerto Rico, and recommends aerial spraying of the toxic pesticide Naled for mosquito control, much to the dismay of many area farmers, activists and concerned citizens who feel that the decision was made without consultation or information provided to the local population. Aerial spraying of pesticides have long been used for mosquito control, but many experts believe that these methods fail to sufficiently manage mosquito populations, increase pesticide resistance, and kill other species that would have acted as a natural predator to mosquitoes. Many experts  agree that combating mosquito-borne diseases should include good surveillance and scientific understanding for controlling mosquito populations, including a focus on  eliminating or managing  breeding areas,  utilizing  biological controls, exclusion from indoor environments with screening, and repellents. An efficient mosquito management strategy emphasizes public awareness, prevention, and monitoring methods. However, if these methods are not used properly or in time, communities must determine if they should risk exposing vulnerable populations to potentially harmful diseases caused by mosquitoes or to chronic or deadly illnesses caused by […]

(Beyond Pesticides, May 27, 2016) Oxitec, a self-described pioneer in using advanced genetics to control target  insects, has petitioned the U.S. Food and Drug Administration (FDA) to grant emergency approval of genetically engineered (GE) mosquitoes to fight the spread of the Zika virus. Oxitec has proposed a trial to determine the efficacy of their self-limiting mosquitoes for the control of Aedes aegypti, a type of mosquito known to transmit the Zika virus, in Key Haven, Monroe County, Florida. However, some in the environmental community are concerned about the possible non-target effects of releasing these genetically modified mosquitoes into nature and urge additional research in the lab. The plan for a release of these GE mosquitoes has been in the works for a while. In February 2015, it was reported that the Florida Keys Mosquito Control District (FKMCD) was working alongside Oxitec to release these GE mosquitoes, but, at the time, the plan had not yet been finalized. A change.org petition against the release garnered over 146,000 signatures and continues to grow, with numbers around 168,000 to this date. In February 2016, Oxitec submitted a draft environmental assessment to FDA, and a month later, FDA published a preliminary finding of no […]

(Beyond Pesticides, May 19, 2016) Using fear without facts, Congress is yet again attempting to gut Clean Water Act (CWA) provisions that protect waterways and communities from excessive pesticide pollution. In a move that was blasted by House Democrats this week, HR 897  (which was introduced as the Reducing Regulatory Burdens Act of 2015) was renamed the  Zika Vector Control Act, despite the fact that the bill does not actually do anything to address the threat of Zika. The legislation was defeated Tuesday on a suspension vote, 262-159, however the bill will be going to the Rules Committee on Monday, with anticipated House floor activity on Tuesday, May 24. (Take action: urge your representative to oppose HR 897.) “In a brazenly political act, the Republican leadership is trying to mask gutting the Clean Water Act as having something to do with fighting Zika,” Drew Hammill, spokesman for House Minority Leader Nancy Pelosi (D-CA), said in a statement to The Hill. “This bill has nothing to do with Zika and everything to do with Republicans’ relentless special interest attacks on the Clean Water Act,” he said. “It will do nothing to stem the growing threat of the Zika virus.” The bill […]

(Beyond Pesticides, February 4, 2016) According to a study published in Oxford University Press, entitled High Levels of Resistance in the Common Bed Bug, bed bugs have developed resistance to neonicotinoids (neonics). Neonics have become one of the most widely used active ingredients to control bed bugs since the insects’ have exhibited  resistance to other chemicals, including synthetic pyrethroids.  Troy Anderson, Ph.D., entomologist at Virginia Tech and Alvaro Romero, Ph.D., entomologist at New Mexico State, studies found higher neonic  efficacy for neonics used on lab bed bugs as compared with bed bugs found in domestic settings. With the resurgence of bed bugs across the U.S., exterminators have relied heavily on insecticides to manage the pesky pests, despite questions about efficacy due to resistance, and viability of alternative, non-toxic solutions. To test the tolerance and ineffectiveness of pesticides used on bed bugs, Drs. Anderson and Romero used four popular neonics (imidacloprid, acetamiprid, dinotefuran, thiamethoxam) to compare their effectiveness in wild and isolated bed bug populations. Bed bugs isolated in a lab died quickly from a small amount of neonics, however, those same chemical treatments used on bed bugs found in Cincinnati and Michigan were ineffective. The isolated group of bed bugs […]

(Beyond Pesticides, February 3, 2016) Speaking to The Guardian, a leading Kenyan entomologist warns that spraying pesticides will fail to deal with the Zika virus. Just recently the World Health Organization (WHO) declared the virus a public health emergency over growing concerns that the virus is linked with microcephaly. Aerial and ground applications of pesticides have long been used for mosquito control, but many believe that these methods fail to sufficiently control mosquito populations, promote resistance and kill other species that would have acted as a natural predator to mosquitoes. Dino Martins, PhD, a Kenyan entomologist in an interview with The Guardian said that while pesticides can reduce the population of  flying adult mosquitoes that transmit the virus, they will fail to deal with the epidemic that threatens to become a global pandemic, and warns that spraying landscapes is extremely dangerous.  “It is a quick fix but you pay for it. You kill other species that would have predated on the mosquitoes. You also create a mosaic of sprayed and unsprayed low densities of chemicals that fosters the rapid evolution of resistance.” Mosquitoes have very short life cycle (a week or less), increasing the probability that each succeeding generation is […]

(Beyond Pesticides, November 13, 2015) Research finds that sound waves could combat the Asian citrus psyllid, an insect that has been devastating Florida orange groves, and possibly reduce the need for pesticides. The Asian citrus psyllid carries a bacteria that causes “citrus greening,” an incurable disease with symptoms that include yellow shoots, uneven discolored patches, and deficiencies with the production of chlorophyll, green pigment found within plants. To stem the spread of the disease  —which is responsible for an estimated $3.63 billion in lost revenue from orange juice for the state of Florida from 2006-2012— researchers at the U.S. Department of Agriculture (USDA) and University of Florida (UF) are developing vibration traps that hijack psyllid mating calls to locally bring their populations under control. “We’re trying hard to cut down on use of pesticides in orange groves, partly because we are worried they’ll build up resistance to pesticides, and that will make things even worse,” said Richard Mankin, Ph.D., a research entomologist with USDA. He presented  findings  on acoustic disruption at the meeting of the American Acoustical Society  last month in Jacksonville. When a male Asian psyllid is looking for a mate, he situates himself on a twig and alerts […]

(Beyond Pesticides September 9, 2015) A young Florida boy and his family are reeling after a routine termite treatment resulted in a devastating outcome. Ten-year-old Peyton McCaughey of Palm City, Florida has been in the hospital for weeks following a severe reaction to chemicals used to fumigate his family’s home. According to news reports, the  fumigation was performed by Sunland Pest Control, a subcontractor of Terminix. The Florida Department of Agriculture has since issued a “Stop Work Order” while it  investigates the company in collaboration with the Environmental Protection Agency (EPA) and the state Department of Health. After returning to their home hours after the Terminix subcontractor told them it was safe to enter, the whole family became very ill. While the parents and the 7-year-old daughter recovered, the young boy’s condition continued to worsen. “He was having some uncontrollable muscle movements, couldn’t stand up, couldn’t speak, so they took him to a local walk-in and the doctor quickly recognized it was probably poisoning from a treatment,” said Peyton’s uncle, Ed Gribben. Current reports indicate that the boy has likely suffered brain damage and has lost all muscle control, rendering him unable to stand or speak. He remains in a […]

(Beyond Pesticides, August 20, 2015) Just as children go  back to school, research  finds that lice in 25 of 30 states in a  U.S. study have developed resistance to common over-the-counter treatments like permethrin, calling into questions the justification for exposing children to a neurotoxic and carcinogenic pesticide and elevating the need to consider nontoxic alternatives. The  research was presented Tuesday at the 250th National Meeting and Exposition of the American Chemical Society (ACS), by Kyong Yoon, Ph.D., of Southern Illinois University, Edwardsville. Classified as a synthetic pyrethroid insecticide, permethrin is “likely carcinogenic” and a suspected endocrine disruptor, immunotoxic, neurotoxic, and highly toxic to fish, aquatic animals, and bees. Dr. Yoon and his colleagues describe the threefold mutations that lice have developed over time due to the constant use of synthetic pyrethroid insecticides. This new finding builds on his team’s previous research, which found that 99.6% of lice are resistant to chemical treatment, adding weight to the fact that chemical treatments not only are unnecessary given effective least-toxic alternatives, but also are not able to provide the lice control that manufacturers claim. “We are the first group to collect lice samples from a large number of populations across the U.S.,” […]

(Beyond Pesticides, August 19, 2015) Local fogging for  mosquito control turned tragic for a Palo Alto, California beekeeper who lost hundreds of honey bees from his backyard hives. The beekeeper, who also produces organic honey, now fears his honey is contaminated. The fogging, which occurred last month, was in response to positive tests for West Nile virus in mosquito samples. Many mosquito control pesticides are toxic to honey bees and given the declining populations of pollinators, vector control officials are being asked to carefully consider the risks associated with pesticide spraying. According to the local NBC affiliate, beekeeper Rondolph Tsien believes he was not given sufficient time to protect his bees from the mosquito fogging and, despite trying to cover his hives with a tarp to protect his bees from drifting pesticides, many were lost. A mosquito sample tested positive for West Nile virus about one mile from Mr. Tsien’s home, putting his property in the catchment area for fogging. Mr. Tsien worries the surviving bees will produce contaminated honey that can no longer be labeled organic. A Santa Clara County Vector Control representative stated during an interview that the county uses  an “extremely low dose” of pesticides during fogging […]

(Beyond Pesticides, July 8, 2015)  Last week, after decades of review and known toxic hazards, especially to children, the Environmental Protection Agency (EPA) accepted a proposed cancellation for  a number of indoor uses (including food establishments) and tolerances of propoxur, a carbamate insecticide known for its toxic effects to  children. EPA has received a Section 6(f) request under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) from the registrant of propoxur to voluntarily cancel certain uses of the carbamate insecticide. The request from the manufacturer, Wellmark International, requests cancellation of  indoor aerosol, spray and liquid formulations of propoxur, indoor crack and crevice use, and all use in food-handling establishments.  EPA previously agreed to an April 1, 2016 phase out of propoxur in pet collars, but has continued to leave open these other avenues of exposure. The agency will begin accepting comments on its  proposal once it has been published in the Federal Register, which is expected to occur within 10 days of the prepublication signature date. It should be noted that EPA engages in lengthy negotiations with pesticide manufacturers, as is the case with propoxur (see recent announcement on chlorpyrifos), rather than pursuing rigorous regulatory standards through its cancellation or […]

(Beyond Pesticides, June 24, 2015) The International Agency for Research on Cancer (IARC) has found that there is some evidence in experimental animals that the popular herbicide, 2,4-D, is linked to cancer and now classifies it as a Group 2B, “possibly carcinogenic to humans.” IARC also classified lindane, used commonly in the U.S. as a topical lice treatment, in Group 1,“carcinogenic to humans” based on sufficient evidence in humans with the onset of non-Hodgkin lymphoma (NHL). These latest cancer findings come just months after the agency classified the world’s most widely used herbicide, glyphosate (Roundup), as “probably carcinogenic to humans,” raising public concerns on the lack of action from U.S. regulators. This month, 26 experts from 13 countries met at the World Health Organization’s (WHO) IARC in Lyon, France to assess the carcinogenicity of the insecticide lindane, the herbicide 2,4-D, and insecticide DDT. The findings are published in the Lancet. The new IARC findings come months after the agency classified glyphosate, the ingredient in the popular Roundup weed killer, as a Group 2A “probable” carcinogen, citing sufficient evidence of carcinogenicity based on laboratory studies. This decision sparked renewed calls for the U.S. Environmental Protection Agency (EPA) to take action on […]

(Beyond Pesticides, June 12, 2015) Without input from or notification to the public, Cornell University  has released genetically engineered (GE) diamondback moths at its  agricultural experiment station in Geneva, New York. The university is testing a new way to  control agricultural  pests, much to the dismay of environmentalists. The moths, which are engineered to be autocidal (self-killing), pose a possible threat to the certification of organic farmers and create environmental risks. Environmental groups such as Food and Water Watch, Center for Food Safety, and Friends of the Earth, among others, sent a letter expressing concern over the U.S. Department of Agriculture (USDA)’s assessment process, which neglected to address  the possibility of moth movement past the trial area, and the impacts that diamondback moth declines will have on their natural predators and the larger ecosystem. These groups are recommending that  all outdoor trials be stopped until more information is available. Cornell has partnered with Oxitec, a self-described  pioneer in using advanced genetics to control target  insects. They plan on controlling the population growth of these GE moths through their genetic design that kills the moth  in the larval stage on plants. Normally, these larvae feed on crops such as broccoli and […]

(Beyond Pesticides, May 26, 2015) A study led by Purdue University Entomology Professor Michael Scharf, Ph.D. finds that small doses of imidacloprid, a neonicotinoid pesticide, can halt the normal functioning of termite behavior, leaving colonies vulnerable to disease and eventual death. While this effect may be celebrated by the pesticide industry as a victory for termite control, it has serious implications for the use of imidacloprid and other neonicotinoid pesticides on all eusocial insects, such as ants and bees. Eusocial insects thrive as a colony, working, living and sometimes even fighting diseases as one organism, rather than as many individuals existing together. Termites, specifically, exhibit a remarkable resistance to many diseases because they engage in social grooming, clearing pathogens off of one another. Other examples of eusociality can be found in ant and bee colonies. Ant colonies create foraging trails and engage in cooperative transport, where they create long chains of ant individuals to form a whole assembly line to transport food back to the colony and work as one to carry large prey that would not be otherwise attainable. Honeybee colonies send out foragers to report back with the location of plentiful food sources so that other bees know […]

(Beyond Pesticides, April 20, 2015) New details emerged last week after a Canadian volunteer group, Pesticide Free Alberta (PFA), received records from the City of Edmonton regarding ground and aerial application of Dursban 2.5, a restricted insecticide (in both Canada and the US), in close proximity to residential areas to kill off mosquito larvae. The coordinator of PFA, Sheryl McCumsey, fought for months for the data to be released. Health Canada does not recommend using Dursban in areas where children will be exposed, such as homes, parks, school grounds or playing fields, but the City of Edmonton justifies the use of the product by its label language, citing that it can be used in industrial areas. These areas often end up bordering residential neighborhoods and natural lands, such as parks. The active ingredient in Dursban is chlorpyrifos, a neurotoxic insecticide that has been linked to many detrimental health and environmental effects, such as endocrine disruption, reproductive and birth effects, toxicity to birds, bees and aquatic wildlife.In the US, the Environmental Protection Agency (EPA) and Dow AgroSciences restricted the sale and use of most home, lawn and garden product due to its health risks for children. However, it is still used […]

(Beyond Pesticides, March 11, 2015)   The White House’s recommendations for pollinator-friendly landscaping at federal facilities are “largely unachievable,” according to trade groups AmericanHort and the Society of American Florists. The groups believe that growing plants that attract and feed honey bees, wild bees, butterflies and other pollinators without a reliance on persistent, systemic and toxic pesticides that can harm them is “not a viable recommendation.” This comes in spite of several initiatives already taken by nurseries across the country to limit or restrict the use of systemic neonicotinoid pesticides on nursery and ornamental plant production. Last fall, the White House Council on Environmental Quality (CEQ) announced new guidelines for federal agencies to incorporate pollinator friendly practices at federal facilities and on federal lands. Critical to pollinator health within these guidelines is a requirement that agencies should “[a]cquire seeds and plants from nurseries that do not treat their plants with systemic insecticides.” Further, the document states that, “Chemical controls that can adversely affect pollinator populations should not be applied in pollinator habitats. This includes herbicides, broad spectrum contact and systemic insecticides, and some fungicides.” Concurrent with CEQ’s announcement, the General Services Administration (GSA) also stated it is in the process […]

(Beyond Pesticides, February 26, 2015) Yesterday, the Environmental Protection Agency (EPA) granted Florida citrus growers an emergency exemption to use the bee-killing pesticide clothianidin to control Asian Citrus Psyllid (ACP), a pest that causes “citrus greening,” a devastating citrus plant disease. Clothianidin, which is not currently registered for use on citrus, is part of a class of neurotoxic, systemic insecticides called neonicotinoids, which have been implicated in global honey bee declines and suspended in the European Union. “EPA needs to assist in stopping the deadly use of pesticides that harm bees, butterflies, and birds with sustainable practices, rather than imperil pollinators with its decisions,” said Jay Feldman, executive director of Beyond Pesticides, a health and environmental advocacy group. He continued, “We understand the immediate chemical needs of chemical-intensive agriculture for increasingly toxic and persistent chemicals, but urge EPA to help stop the treadmill, lest it allow irreversible harm to the environment, biodiversity, and human health.” Beyond Pesticides is urging EPA to require that growers adopt a management plan in order to apply clothianidin. “Ultimately, EPA should be requiring growers to adopt integrated organic systems to manage pests, as a part of an emergency permit,” said Mr. Feldman. Read Beyond Pesticides’ […]

(Beyond Pesticides, February 3, 2015) Officials in the Florida Keys are seeking approval from the U.S. Food and Drug Administration (FDA) to release a wave of mosquitoes that have been genetically engineered to produce offspring whose larvae are unable to survive. The plan to introduce these mosquitoes has been met with intense skepticism by local residents. A change.org petition against the release has garnered over 146,000 signatures to date. Florida Keys Mosquito Control District (FKMCD) officials have been planning the release alongside British biotechnology company Oxitec, which has already conducted similar experiments with the genetically engineered (GE) mosquitoes in Brazil and the Cayman Islands. Websites for Oxitec and the FKMCD assert that the GE aedes aegypti mosquitoes will significantly lower the numbers of the disease spreading insects, and reduce the need to spray insecticides. Opponents counter that the introduction of the modified mosquitoes is unacceptably risky, as there has been little research on possible non-target effects of the novel insect, and current control methods and public education have been successful at controlling exotic diseases. Opportunity for public comment to FDA and the U.S. Centers for Disease Control and Prevention is likely to occur in the near future. Behind the Technology […]

(Beyond Pesticides, August 28, 2014) It’s back to school time again, which for many of our readers and parents across the country means the unnerving possibility of hazardous pesticide exposure at school from well-intentioned but misguided attempts to create a germ and pest-free environment. Because children face unique hazards from pesticide exposure due to their small size and developing organ systems, using toxic chemicals to get rid of pests and germs harms students much more than it helps. Fortunately, parents and teachers have many options for safer techniques and strategies to implement a pest management program at schools without relying on these toxic chemicals. Additionally, schools can further their students’ education beyond the lessons of the text book by providing habitat for wildlife and growing organic food in a school garden.  By going organic, your child’s school can become a model for communities across the nation. Beyond Pesticides has put together this back-to-school checklist of programs and steps you can take to ensure that you are sending your kids back to a healthier and safer environment. Get Organized and Improve Your School’s Pest Management Program Whether you’re a parent, community activist, landscaper, school administrator or employee, use these steps to […]

(Beyond Pesticides, July 28, 2014) New research from Michael Skinner, Ph.D.’s laboratory out of Washington State University finds that —yet again”” exposure to pesticides may have devastating consequences for future generations. The study, “Pesticide Methoxychlor Promotes the Epigenetic Transgenerational Inheritance of Adult-Onset Disease through the Female Germline,” published in PLOS ONE, finds that gestating rats exposed to the pesticide methoxychlor develop a higher incidence of kidney disease, ovary disease and obesity in offspring spanning three generations. The incidence of multiple diseases increased in the third generation or “great-grandchildren.” This study suggests that ancestral exposures to methoxychlor over the past 50 years in North America may play a part in today’s increasing rates of obesity and disease. The epigenetic changes observed were specific to methoxychlor exposure and, according to researchers, may prove to be valuable biomarkers for future research on transgenerational disease. For people exposed to the pesticide, Dr. Skinner says his findings have implications such as reduced fertility, increased adult onset disease and the potential to pass on those conditions to subsequent generations. “What your great-grandmother was exposed to during pregnancy, like the pesticide methoxychlor, may promote a dramatic increase in your susceptibility to develop disease, and you will pass […]

(Beyond Pesticides, July 21, 2014) According to figures released by the British Government last week, over 60% of the county’s bread supply is tainted with pesticide residues. This is a shocking increase from numbers recorded in 2001, which found 28% of bread to be tainted. According to the Department for Environment, Food and Rural Affairs (Defra) Expert Committee on Pesticides Residues in Food (PRIF), 2,951 bread samples were tested. According to a Pesticide Action Network UK report, a majority of the reoccurring pesticides were glyphosate and chlormequat. Glyphosate is an herbicide that can lead to non-Hodgkin’s Lymphoma, genetic damage, cancer, reproductive issues, liver damage, and endocrine disruption as well environmental damage such as water contamination and harmful effects to amphibians. Unfortunately, very little research has been done on what the effects can be on humans. Chlormequat, the second most-commonly found pesticide in British bread, is a plant growth regulator. A study conducted by the UN’s Food and Agriculture Organization (FAO) linked Chlormequat to developmental toxicity in animals. Very little research has been performed assessing the public health impact of this pesticide. In the U.S., it is only allowed for use on ornamental plants. Pan UK spokesman Nick Mole said, “The […]

(Beyond Pesticides, July 18, 2014) After years of struggling to combat the rise of Lyme disease in the region, Loudoun County, Virginia has decided to forgo the spraying of a hazardous pesticide in public parks in favor of public education and continued surveillance of park lands. Controversy over spraying arose back in 2012 when Loudoun began ramping its spray program to manage ticks, often the carrier of the disease. Loudon County used the pesticide Talstar, which contains the active ingredient bifenthrin, a neurotoxic chemical whose use raises public health and product efficacy concerns, as documented by the Centers for Disease Control and Prevention. Beekeepers expressed concern that spraying would greatly damage their bee colonies, as bifenthrin is highly toxic to bees, while conservationists were concerned with the chemicals leaching into waterways and killing aquatic life. At the same time, some researchers point out that there was no evidence that spraying the chemical would reduce the number of Lyme disease infections. After years of debate and data analysis,  David Goodfriend, M.D., M.P.H, director of the Loudoun County Health Department, said that the county’s Lyme Disease Commission’s recommendation was to not spray any of the properties. The recommendation was based on two […]
