(Beyond Pesticides, May 3, 2013) Despite the groundbreaking decision in Europe earlier this week to protect honey bees by suspending the neonicotinoid pesticides shown to be highly toxic, the  U.S. Department of Agriculture (USDA) and the U.S. Environmental Protection Agency (EPA) released a report yesterday which fails to address the overwhelming scientific evidence of neonicotinoid-related bee death and decline. The report presents no long-term, sustainable solutions to address the current bee crisis. Instead, the report recommends further research on the role of pesticides in honey bee health, further highlighting the stymied pace of U.S. regulatory efforts. The report follows on the National Stakeholders Conference on Honey Bee Health, which was led by federal researchers and managers and Pennsylvania State University in October 2012. Stakeholders at the conference included industry, federal officials, scientists, beekeepers, and activists who discussed several factors pertaining to adverse pollinator heath. Parasites, disease, genetics, poor nutrition, and pesticide exposure were highlighted at the meeting as synergistic factors in the observable nationwide honey bee decline. The report recommends further research on the impacts of pesticides on bees at the colony level in the field, but does not capture the science connecting pesticides to adverse effects or the need […]

(Beyond Pesticides, April 30, 2013) A landmark decision by the European Commission on Monday means that bee-killing, neonicotinoid pesticides will experience a continent-wide ban in Europe for two years. A  15 Member States majority  supported the ban, with eight against, and four abstaining. European Health and Consumer Commissioner Tony Borg explains, “Since our proposal is based on a number of risks to bee health identified by the European Food Safety Authority (EFSA), the Commission will go ahead with its text in the coming weeks. I pledge to do my utmost to ensure that our bees, which are so vital to our ecosystem and contribute over €22 billion annually to European agriculture, are protected.” The ban comes several months after the EFSA released a report identifying “high acute risk” to honey bees from uses of certain neonicotinoid chemicals. The moratorium will begin no later than December 1 this year. “We’re happy to see the EU take a leadership role to remove from the market these chemicals associated with colony collapse disorder and hazards to bee health. We’ll continue to push the U.S. Environmental Protection Agency (EPA) through legal and advocacy means to follow-up with urgent actions needed to protect bees,” says […]

(Beyond Pesticides, April 17, 2013)  Beekeepers in Bulgaria are revving up protests calling for a moratorium on the use of pesticides hazardous to bees, with a nationwide demonstration scheduled for Earth Day on April 22. The beekeepers are citing European and Bulgarian studies saying that neonicotinoid pesticides harm the immune systems of bees, shortening their lives and aggravating the mass disappearance of bee colonies. At an April 10 march, beekeeper Hristo Stoikov told Bulgarian National Television that in the past three years close to 60 percent of the bee population had disappeared. If the government failed to act, Bulgaria would be left with no bees. Separate reports said that about 200, 000 bees died in Bulgaria in 2012, about 20 per cent of the country’s bee population. The Union of Bulgarian Beekeepers is citing European and Bulgarian studies saying that neonicotinoid pesticides harm the immune systems of bees, shortening their lives and aggravating the mass disappearance of bee colonies. Beekeepers are upset that in the most recent European Union (EU)-level vote on banning the use of three neonicotinoid pesticides — clothianidin, thiamethoxam and imidacloprid, Bulgaria was among countries that abstained. At the beginning of 2013, the European Commission asked […]

(Beyond Pesticides, April 15, 2013) British supermarket chain, Waitrose Limited, has made the decision to phase out the use of bee-toxic neonicotinoid insecticides across its supply chain. This is happening in lieu of strong regulatory changes expected by the European Union (EU). The company, which has more than 200 branches across the UK, told its fruit, vegetable, and flower suppliers that they would have until the end of 2014 to stop using neonictoinoids, in particular imidacloprid, clothianidin, and thiamethoxam. These restrictions, delineated in Waitrose’s new Seven Point Plan for Pollinators, will eventually extend to some of their commodities, including oil seed and corn; however, the company did not announce any timeline for this phase-out. The managing director, Mark Price, released a statement that said, “Waitrose aims to be a restorative retailer, putting back more than we take from the environment, and we believe our decision on the three formulations of neonicotinoids is appropriate until conclusive evidence is put forward about the effects of these three chemicals.” The move follows in the footsteps of other high profile garden centers, hardware stores, and DYI retailers that have already stopped supplying these harmful chemicals on their shelves. Nevertheless, Waitrose’s commitment to the pollinator […]

(Beyond Pesticides, April 10, 2013) In response to the United Kingdom (UK) blocking attempts to introduce a Europe-wide ban on the world’s most widely used insecticides – neonicotinoids, some members of parliament (MPs) from the environmental audit committee (EAC) chided their government last week for relying on “fundamentally flawed” studies and failing to uphold its own precautionary principle, saying that the UK must suspend the use of the pesticides linked to serious harm in bees. The UK environment secretary, Owen Paterson, must end his department’s “extraordinary complacency” and suspend the use of pesticides linked to serious harm in bees, according to a damning report from an influential cross-party committee of MPs. The UK is blocking attempts to introduce a Europe-wide ban on the world’s most widely used insecticides, neonicotinoids, arguing that the scientific evidence is inconclusive. But MPs on parliament’s green watchdog, the environmental audit committee (EAC), said the government was relying on “fundamentally flawed” studies and failing to uphold its own precautionary principle. The EAC report criticizes ministers and the Department for Food, Environment and Rural Affairs (Defra) for their “extraordinarily complacent approach to protecting bees”. The report calls on the government to impose a ban on imidacloprid, clothianidin […]

(Beyond Pesticides, April 9, 2013) Last Wednesday, close to a hundred people attended a public hearing at the Riverhead campus of Suffolk County Community College, sponsored by the Department of Environmental Conservation (DEC), to comment on the draft of the Long Island Pesticide Pollution Prevention Strategy. The strategy, which was released in January, is dramatically different than a draft plan DEC had released in 2011. The draft plan had initially received praise from environmental organizations for its “zero tolerance policy”  to ensure certain chemicals did not end up in Long Island’s drinking water. However, the revamped strategy fails to offer any meaningful protective measures or strong pesticide regulations. This is concerning, given trace amounts of metalaxyl, imidacloprid and atrazine have been repeatedly detected in test wells, along with 117 other pesticides detected in Long Island drinking water. State officials argued that pesticide levels in Long Island’s drinking water are far below federal standards. However, the pesticides that have been found in the drinking water have been linked to several health and environmental problems. Because of these health and environmental risks the Citizens Campaign for the Environment, a grassroots organization working in Long Island, has called for DEC to ban […]

(Beyond Pesticides, April 3, 2013)  Last week, Syngenta and Bayer CropScience proposed an action plan to forestall pending European Union (EU) restrictions on their neonicotinoid products that have been linked to global bee declines.  Stating that a ban on their products would not save hives, the plan focuses on implementing agricultural best management practices, planting habitat, and new research and development, all of which fail to seriously address the real problem that their products are highly toxic to bees. This new industry plan comes on the heels of the European Union (EU) stalemate on bee health, and after the EU food safety agency concluded that certain neonicotinoids pose unacceptable risks to bees. Public and regulatory scrutiny is now focused on the class of chemicals — neonicotinoids— linked to bee health decline. Neonicotinoids have been shown by numerous studies to adversely impact the health of  bees, as well as  birds and aquatic organisms. Beyond Pesticides, Center for Food Safety, and Pesticide Action Network North America joined beekeepers and other environmental and public health advocacy groups to sue the U.S. Environmental Protection Agency (EPA), calling for the suspension of the neonicotinoids, clothianidin and thiamethoxam. The science continues to document these […]

(Beyond Pesticides, March 29, 2013) Two studies released Wednesday support the findings of the European Food Safety Authority that neonicotinoid insecticides pose an unacceptable risk to bees. The pair of British studies indicate that neonicotinoids and miticides cause brain damage, compromising bee survival. The study, published in Nature Communications by researchers at the University of Dundee and Newcastle University, concludes that imidacloprid  and clothianidin, a commonly used insecticides on crops and plants, as well as the organophosphate miticide coumaphos, a treatment for Varroa bee mites, cause cognitive damage in bees. The research indicates that within 20 minutes of exposure to pesticides the neurons in the learning center of the brain stop firing, causing “epileptic type” hyperactivity. While the bees are still alive, the lobes of the brain fail to communicate with each other with obvious implications for their survival, Another study, published in the Journal for Experimental Biology by a team of Newcastle scientists, links imidacloprid and coumaphos to learning and memory impairment. The research indicates that brain damage from pesticides makes it more difficult for bees to forage and find food, and when they find the food they have trouble locating and returning to their hives. In sum, the […]

(Beyond Pesticides, March 18, 2013) The bee-killing neonicotinoid insecticides used for agriculture will continue to be used across the European Union (EU), as members failed to reach an agreement on the proposal to suspend their use on flowering crops over the next two years. The proposal had followed reports released by the European Food Safety Authority (EFSA), which found the continued use of neonicotinoids to be an unacceptable “high acute risk” to pollinators, particularly honey bees. However, three EU members opposed the plan to suspend, blocking the European Commission from attaining a qualified majority to adopt the proposed suspension. “The commission put the text to the vote and no qualified majority was reached, either in favor or against the text,” the European Commission said in a statement. Those opposing the proposal, notably UK and German Ministers, argued that more scientific evidence was needed as a suspension could cause disproportionate damage to food production, counter to research indicating bee declines also damage crop productivity. Pesticide companies Bayer and Syngenta have pressed hard following the EFSA report to effect this outcome. The decision, or lack thereof, runs contrary to a precautionary approach to ensuring healthy bees as critical for our food production […]

(Beyond Pesticides, February 12, 2013)  Is 2013 the year colony collapse disorder (CCD) begins impacting our food supply? According to the American Bee Journal, almond growers in California may not have access to the honey bee colonies necessary to pollinate this year’s crop. “We need 1.6 million colonies, or two colonies per acre, and California has only about 500,000 colonies that can be used for that purpose. We need to bring in a million more colonies but due to the winter losses, we may not have enough bees,” says Eric Mussen, PhD,  extension apiculturist at the University of California Davis (UC Davis) Department of Entomology. The problem, Dr. Mussen explains, is due to heavy losses this winter and less populous hives overall. Some beekeepers are reporting astonishing winter losses upwards of 90 percent, and in select cases complete colony loss. Honey production in 2012 was one of the worst years in the history of the United States, Dr. Mussen notes. Less honey means less food for overwintering bees, putting increased stress on colonies attempting to fight off the spread of CCD. CCD is the name given to the precipitous decline of honey bee populations around the world beginning in […]

(Beyond Pesticides, February 1, 2013) The European Commission announced yesterday its position against the use of neonicotinoid insecticides, pushing nations within the European Union (EU) to impose a two year suspension on their use. The proposal, put forward at a meeting of the Standing Committee on the Food Chain and Animal Health, would restrict the application of neonicotinoids as granules, seed-treatment or spray, on crops that are attractive to bees, particularly, sunflowers, rapeseed, corn, cotton, and cereal crops. Environmental groups say that this decision should signal the way forward for the U.S. Environmental Protection Agency (EPA) to suspend neonicotinoids in the U.S. “It’s a great thing,” said New York beekeeper Jim Doan, “I’m hoping that the EPA follows in their footsteps. While I recognize our government works differently, it says something that the European government has recognized the overwhelming data on the impact of these pesticides.” The announcement comes on the heels of research conducted by the European Food Safety Authority (EFSA) which indicated that three neonicotinoid insecticides””imidacloprid, clothianidin, and thiamethoxam, produced by Switzerland’s Syngenta and Germany’s Bayer, pose an unacceptable hazards to honey bees. In its report released January 16th, EFSA concludes that systemic contamination of neonicotinoid-treated crops, neonicotinoid […]

(Beyond Pesticides, January 17, 2013) The European Food Safety Authority (EFSA) yesterday presented its report which finds that the neonicotinoid class of insecticides poses unacceptable hazards to bees. The report concludes that certain crops treated with neonicotinoid chemicals –imidacloprid, clothianidin and thiamethoxam– are of “critical concern” for bee health. Beekeepers and environmental activists welcome these recent scientific findings that they say support a U.S. ban on these chemicals. According to Jay Feldman, Executive Director, Beyond Pesticides, “The EFSA report confirms what we have been asking EPA to recognize. Clothianidin and other neonicotinoids are highly toxic to bees, and should be banned by EPA and removed from the environment.” In its investigation, EFSA, which was tasked with assessing the risks associated with these chemicals to bee colony survival and development, found that systemic contamination of neonicotinoid-treated crops and contamination via dust place honey bees and the hives they return to at high risk. Exposure to contaminated dust pose a high risk to honey bees for all three neonicotinoids used on corn and certain other crops, as well as exposure to residues in nectar and pollen. High risks were also identified from exposure to guttation fluid from corn for thiamethoxam. EFSA considered […]

(Beyond Pesticides, December 19, 2012) The Congressional Research Service (CRS) issued its overview report, Bee Health: The Role of Pesticides, in response to a congressional request for more information on the connection between declines in bee populations, colony collapse disorder (CCD) and pesticides, particularly neonicotinoids. The 23-page report, dated December 11, 2012, summarizes the range of scientific studies and regulatory activities without offering a critique of what bee health advocates have identified as serious deficiencies in the regulatory review process and compliance with the pesticide registration law. The review gives equal standing to independent and industry science. The CRS report identifies a range of issues regarding: 1. Changes to managed and wild bee populations (indicating limited information); 2. Factors that are documented to impact bee health, including pesticides, pests and diseases, diet and nutrition, genetics, habitat loss, and beekeeper issues, highlighting that there are multiple exposure pathways that may work synergistically; 3. Scientific research on the role of pesticides; and, 4. Current research and regulatory activity regarding neonicotinoids, a neurotoxic insecticide impacting bees. The report reviews the ‘state of play’ on the issue of bee declines and finds that there are reported to be many factors that contribute to the […]

(Beyond Pesticides, December 14, 2012) Decision making advice by the Advisory Committee on Pesticides (ACP) and insecticide regulator, the Department for Environment, Food, and Rural Affairs (Defra), were harshly criticized on Wednesday by Members of Parliament (UK), as they discussed the problems associated with neonicotinoids, a group of neurotoxic insecticides linked to serious declines in bee and pollinator populations. The meeting was attended by Members of Parliament, members of the Advisory Committee on Pesticides, Lord de Mauley, the Parliamentary Under-Secretary of State, the Department for Environment, the Food and Rural Affairs and officials, bringing neonicotinoids and their impact on bees to the attention of the international community as well as at home. The discussion focused on the evidence used to make a decision on the allowance of neonicotinoids and plans for the future. ACP members indicated that evidence for future draft plans would be based on new studies developed in 2012 on the effects of neonicotinoids at the colony level, as well as the impact of neonicotinoids exposure in field tests, rather than in the lab. Research will likely fill the extant data gaps, the most important of which were identified by officials of Defra, the environmental regulatory agency in […]

(Beyond Pesticides, October 23, 2012) It’s a story we’ve heard for far too long. Research published yesterday in the journal Nature concludes that when bees are exposed to pesticides their colonies have a greater propensity to fail, again raising the urgent need for regulatory action to protect pollinators. This study adds to the body of science that shows toxic pesticide dependency in agriculture is undermining our food supply. Concerned citizens Take Action! Join us this Thursday, October 25th at Noon outside EPA Headquarters (340 12th St NW (12th and Pennsylvania Ave)) for a rally to tell EPA that it must act to protect pollinators now. The rally will feature speakers from various nonprofit and environmental organizations, commercial and urban beekeepers, film documentarians and more, including: Ӣ David Hackenberg, Commercial Beekeeper, PA Ӣ Jay Feldman, Executive Director, Beyond Pesticides Ӣ Peter T. Jenkins, Attorney/Consultant, Center for Food Safety Ӣ Jim Doan, Commercial Beekeeper, NY Ӣ Maryam Henein, Director “Vanishing of the Bees” Ӣ Meme Thomas, Baltimore City Beekeeper Ӣ Kevin Hansen, Director of “Nicotine Bees” and Sierra Club Representative The Nature study, “Combined pesticide exposure severely affects individual- and colony-level traits in bees,” followed 40 bumblebee colonies for four weeks.

(Beyond Pesticides, September 18, 2012) Take Action! On September 25, EPA will close its public comment period for the petition requesting the agency to suspend the bee-killing pesticide clothianidin. The U.S Environmental Protection Agency (EPA) has failed to recognize that pollinators face unique hazards from clothianidin, a neonicotinoid pesticide which is linked to disruptions in bee mobility, navigation, and feeding behavior. So far thousands of concerned beekeepers, gardeners, hobbyists and folks like you have told EPA to suspend clothianidin and protect pollinators now! Without your support, clothianidin’s effects on honey bees will continue to put beekeepers, rural economies, and our food system at risk. With one in three bites of food reliant on honey bee pollination, it’s imperative that we act now! Tell EPA to suspend the use of the bee-killer clothianidin and protect pollinators. See sample comments here. If you are having trouble submitting to the docket, click here. Background Colony Collapse Disorder (CCD) is the name given to the mysterious decline of honey bee populations around the world beginning in 2006. On average, the U.S. Department of Agriculture (USDA) reports that beekeepers have been losing over 30% of their honey bee colonies each year—but some are losing many […]

(Beyond Pesticides, June 25, 2012) The Canadian governmental authority responsible for pesticide registration has expanded its re-evaluation of neonicotinoid pesticides to include two additional compounds linked to honey bee deaths and Colony Collapse Disorder (CCD). Health Canada’s Pest Management Regulatory Agency (PMRA) announced on June 12 that it has added clothianidin and thiamethoxam and their associated products to its ongoing re-evaluation of imidacloprid. The re-evaluation of these pesticides will focus on resolving issues related to environmental risk and specifically the potential effects of neonicotinoids on pollinators. The re-evaluation will consider all agricultural uses of neonicotinoid insecticides, including soil applications, seed treatment, as well as foliar and greenhouse uses. The Canadian announcement follows France’s decision earlier this month to initiate its own review for thiamethoxam that could result in the cancelation of allowances for using the pesticide. Neonicitinoids are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar, and gutation droplets from which bees forage and drink. Neonicotinoids are particularly dangerous because, in addition to being acutely toxic in high doses, they also result in serious sublethal effects when insects are exposed to […]

(Beyond Pesticides, May 25, 2012) Biologists at the University of California at San Diego (UCSD) have discovered that a small dose of the commonly used neonicotinoid crop pesticide imidacloprid turns honey bees into “picky eaters” and affects their ability to recruit their nestmates to otherwise good sources of food. The results of the experiments, detailed in this week’s issue of the Journal of Experimental Biology (abstract), shed light on one of the main culprits suspected to be behind the recent declines in honey bee colonies and detail the particular ways that the substance impedes the functions of the colony. Since 2006, beekeepers in North America and Europe have lost about one-third of their managed bee colonies each year due to “colony collapse disorder.” While the exact cause is unknown, researchers believe pesticides have contributed to this decline. One group of crop pesticides, called “neonicotinoids,” has received particular attention from beekeepers and researchers. Neonicotinoids, including clothianidin and thiamethoxam, in addition to imidacloprid, are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. They are […]

(Beyond Pesticides, May 21, 2012) American farmers are growing increasingly more frustrated with the lack of commercially available seeds that have not been pretreated with pesticides. Farmers across the Midwest have called on federal officials this week to provide greater access to seeds without pesticide treatments. The request comes as scientists and beekeepers highlight the nearly pervasive use of neonicotinoids as seed treatments on corn as a critical factor in recent bee die-offs, including colony collapse disorder (CCD). Beekeepers from Minnesota to Ohio to Canada report large losses after their hives forage near treated cornfields. Scientists from Purdue University and a multi-year series of studies from Italy point to toxic dust, or neonicotinoid-contaminated powder from recently planted corn fields as key pesticide exposure pathways for bees. The request comes on the heels of a report aired by NBC Nightly News this week entitled “Bee Deaths Linked to Pesticides”, as well as recent reports of large bee kills in Ohio. “Farmers want to be good stewards and neighbors by purchasing seeds and growing corn that supports healthy honey bees and successful beekeepers,” said Doug Voss, a Minnesota corn farmer who also keeps beehives. We have a genuine concern with the majority […]

(Beyond Pesticides, April 3, 2012) Last week, the journal Science published two new studies linking neonicotinoid pesticide exposure to bee health. These two studies, one French, one British, add to a growing body of scientific literature and strengthen the case for removing pesticides toxic to bees from the market. The French study shows that pesticides interfere with honey bee brains, affecting their ability to navigate. The British research finds that pesticides prevent bumble bees from collecting enough food to produce new queens. These studies were released on the heels of an emergency legal petition by beekeepers and environmental groups, including Beyond Pesticides, that calls for the ban of the bee-killing pesticide clothianidin. Neonicitinoids are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. They are particularly dangerous because, in addition to being acutely toxic in high doses, they also result in serious sublethal effects when insects are exposed to chronic low doses, as they are through pollen and water droplets laced with the chemical as well as dust that is released into the […]

Feb
(Beyond Pesticides, February 28, 2012) A study by researchers at the University of Padova in Italy and published in the journal Environmental Science and Technology has confirmed the findings of previous research showing that honey bees are exposed to toxic neonicotinoid insecticides during spring seed planting. Neonicotinoids are known to be highly toxic to honey bees and, yet, are used on millions of acres through North America every year. These findings lend even greater urgency to the need to take these chemicals off the market and ensure the continued survival of honey bees and the essential pollination services that they provide for our food system. Neonicotinoids, including clothianidin, imidacloprid, and thiamethoxam, are most commonly applied by coating crop seeds with the chemical. When these treated seeds are planted, the chemical becomes part of the plants vascular system and stays in the plant for the duration of its lifetime, expressing itself in the pollen. Previously, it had been thought that bees were only exposed to these chemicals through pollen and water droplets from treated plants, which would occur later in the season once the plants had grown and bloomed. However, the Italian study shows that bees are actually exposed to high […]

(Beyond Pesticides, January 24, 2012) Research published this month in the online edition of the Bulletin of Environmental Contamination and Toxicology finds that the neonicotinoid pesticide imidacloprid contaminates surface waters in agricultural regions. Imidacloprid is a systemic pesticide, meaning it is taken up by a plant’s vascular system and expressed through pollen, nectar, and gutation droplets, and is highly toxic to bees, birds and aquatic organisms. The study, “Detections of the Neonicotinoid Insecticide Imidacloprid in Surface Waters of Three Agricultural Regions of California, USA, 2010—2011,” concludes that imidacloprid commonly moves offsite and contaminates surface waters at concentrations that could harm aquatic organisms following use under irrigated agriculture conditions. Researchers at the California Department of Pesticide Regulation collected 75 surface water samples from three agricultural regions of California and analyzed them for contamination with imidacloprid. Samples were collected during California’s relatively dry-weather irrigation seasons in 2010 and 2011. Imidacloprid was detected in 67 samples (89%); concentrations exceeded the U.S. Environmental Protection Agency’s (EPA) chronic invertebrate Aquatic Life Benchmark of 1.05 ĂŽÂĽg/L (micrograms per liter) in 14 samples (19%). Concentrations were also frequently greater than similar toxicity guidelines developed for use in Europe and Canada. A benchmark is a chemical concentration, specific […]

(Beyond Pesticides, January 11, 2012) On January 10, beekeepers from across the country gathered at a national conference, with environmental organizations at their side, to draw attention to the growing plight facing their industry —the decline of honey bees, a problem that has far reaching implications for the U.S. economy. The disappearance of the bees alerts us to a fundamental and systemic flaw in our approach to the use of toxic chemicals -and highlights the question as to whether our risk assessment approach to regulation will destroy our food system, environment, and economy. “Bees and other pollinators are the underpinnings of a successful agricultural economy,” said Brett Adee, Co-Chair of the National Honey Bee Advisory Board and owner of Adee Honey Farms. “Without healthy, successful pollinators, billions of dollars are at stake.” Many family-owned beekeeping operations are migratory, with beekeepers traveling the country from state-to-state, during different months of the year to provide pollination services and harvest honey and wax. Bees in particular are responsible for pollinating many high-value crops, including pumpkins, cherries, cranberries, almonds, apples, watermelons, and blueberries. So any decline in bee populations, health and productivity can have especially large impacts on the agricultural economy (see factsheet). Honey […]
