(Beyond Pesticides, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

(Beyond Pesticides, April 25, 2016) Last week, the City Council of Milwaukie, Oregon passed a resolution that halts the use of bee-toxic neonicotinoid insecticides on city government and public property,  joining the growing number of local governments protecting pollinators.  Neonicotinoids  (neonics) have been widely cited in the demise of both managed and wild bee and pollinator populations.  The resolution specifically  restricts city government agencies from purchasing plants and seeds that have been treated with neonicotinoids and other systemic insecticides and urges public and private landscapers and homeowners to plant bee-friendly habitats.  Clackamas County will join with the Mayor’s office and City Council of Milwaukie to adopt an Integrated Pest Management Plan that mirrors the resolution. In addition to these stipulations, the City of Milwaukie is using this resolution to: urge all businesses, homeowners, and homeowner’s associations operating within the City ensure no plants, seeds, or products containing neonicotinoids are purchased, sold, or used within the City; and to clearly and accurately label any plants or materials that have been treated with a neonicotinoid or neonicotinoid-like insecticide; require that commercial pest service providers performing services on behalf of the City provide landscape services that encourage pollinator populations and support pollinator services; […]

(Beyond Pesticides, April 22, 2016) Today is Earth Day! As honey bees and other pollinators continue to suffer from staggering global declines, Beyond Pesticides works year-round through the BEE Protective campaign, launched Earth Day 2013, to support nationwide local action aimed at protecting pollinators from pesticides. Pollinators are a vital part of the environment, a barometer for healthy ecosystems, and critical to the nation’s food production system. With one in three bites of food reliant on bees and other species for pollination, the decline of honey bees and other pollinators demands swift action. The BEE Protective campaign includes a variety of educational materials to help encourage municipalities, campuses, and individual homeowners to adopt policies and practices that protect bees and other pollinators from harmful pesticide applications and create pesticide-free refuges for these critical  organisms. In addition to scientific and regulatory information, BEE Protective also assists people and communities with  a model community pollinator resolution and a pollinator protection pledge. Insecticides, specifically neonicotinoids, have increasingly been linked to bee declines. These chemicals are used extensively in U.S. agriculture, especially as seed treatment for corn and soybeans. Agriculture is not the only concern however, as pesticide applications in home gardens, city parks, […]

(Beyond Pesticides, April 7, 2016) Last month, the U.S. Environmental Protection Agency (EPA) introduced the Safe Choice Program (not to be confused with Beyond Pesticides’ longstanding Safer Choice program), an overhauled labeling system created by Design for the Environment (DfE) that encourages consumers to seek out and use cleaning products that protect public health and the environment. Safer Choice uses the technical expertise of its DfE workgroup of EPA scientists to compare ingredients in the same functional class and thereby identify those ingredients with the lowest hazard profile. In order to earn a Safer Choice Standard label, products must have chemical ingredient formulations that “function in making the product work,” which allows formulators “to use those ingredients with the lowest hazard in their functional class.” Safer Chemical Ingredients are listed on EPAs website. “EPA’s Safer Choice program helps consumers find products that are productive and contain ingredients that are safer,” said EPA Mid-Atlantic Regional Administrator Shawn M. Garvin. “Products that carry the Safer Choice label have been carefully evaluated by EPA scientists to ensure they contain ingredients that are safer for both humans and environmental health.” The  Safer Choice Standard  and the  Criteria for Safer Chemical Ingredients  are protective and […]

(Beyond Pesticides, April 5, 2016) Populations of wild, ground-nesting bees grow smaller in areas where agricultural production is high, according to Cornell University researchers. Both wild and managed pollinators are experiencing global population declines that have been linked to a range of factors stemming from human activity, to habitat loss, the spread of parasitic mites and diseases, climate change, and significantly, the use of toxic, systemic pesticides. This study underscores the wide ranging threat that conventional agricultural practices pose to wild insect pollinators. Cornell researchers explore the relationship between intensive agricultural production and the size of ground-nesting Andrena nasonii bees. These charismatic pollinators dig tunnels in the ground up to three  feet deep in which they store honey and nectar, and ultimately lay a single egg. They forage on a variety of fruit crops, and are well known and important pollinators of strawberries. Thus, scientists brought their study to areas in New York with large strawberry plantations. Researchers discovered a significant, positive correlation between the decreased size of female A. nasonii bees and their proximity to intensively farmed strawberry plots. “Once we knew there was an effect of agriculture on the size of the bees, we took a random sample […]

(Beyond Pesticides, April 4, 2016) Pesticides widely used in rice paddies in Japan are harming  dragonflies. The study, conducted by researchers at Japan’s National Institute for Environmental Studies, finds that the insecticide fipronil significantly reduces the population of adult dragonflies, more so than any other pesticide treatment. The study, titled Fipronil application on rice paddy fields reduces densities of common skimmer and scarlet skimmer  and published in the journal Scientific Reports, investigated the impact of neonicotinoids, which have been linked to bee die-offs around the world, and chlorantraniliprole, which, like neonicotinoids and fipronil, is a systemic pesticide that is taken up by the plant and subsequently expressed in pollen, nectar, and guttation droplets. Plankton species were adversely  affected by clothianidin, a neonicotinoid, and chlorantraniliprole, but they recovered after concentrations of the chemicals decreased. Koichi Goka, Ph.D., a senior researcher at the institute, said nymphs living near the soil are particularly vulnerable to toxic chemicals, according to The Asahi Shimbun. “The density of insecticidal components in the water drops quickly after they are dissolved,” Goka said. “But such components long remain in the soil. Nymphs at the bottom of water could have been affected.” Dr. Goka is calling for more testing […]

(Beyond Pesticides, March 21, 2016) Last Thursday, Boulder County (CO) commissioners directed staff to draft up a plan to phase out genetically engineered (GE) crops on all farmland owned  by the county. The county’s current policy, adopted in 2011, allows tenant farmers to grow certain types of GE corn and sugar beets on land leased through Boulder County, and will remain in effect at least until the end of the year. The five-year policy old has frequently come under fire from individuals and environmental groups that challenge the safety of GE crop production systems, and their effect on human health, water quality, soil health, and the overall environment. The Boulder County commissioners heard  recommendations from the county’s advisory committees, including the county’s Croplands Policy Advisory Group, the Food and Agriculture Policy Group, and the Parks and Open Space Advisory Group. A public hearing was held on Feb. 29  also provided public input on whether to continue or change the current approval in Section 6.1 of the Boulder County Parks & Open Space Cropland Policy that allows for the use of certain genetically engineered (GE) crops on Open Space land. That approval expires on December 20, 2016. More than 100 people […]

(Beyond Pesticides, March 16, 2016) Another study, this time from researchers at the University of Guelph, finds that at very low levels the neonicotinoid pesticide thiamethoxam affects  the foraging behavior of bumble bees, changing their floral preferences, hindering their ability to learn and extract nectar and pollen. This study is one of many that detail the negative effects of pesticides on bees’ learning behavior and ability to pollinate essential crops. Pesticides, like the neonicotinoid class of insecticides, have been implicated in the global decline of pollinator populations, while advocates call for  limiting pesticide exposures to reverse population declines. According to the authors of this Canadian study, “Chronic exposure to a neonicotinoid pesticide alters the interaction between bumblebees and wild plants, “published in  the journal Functional Ecology, it is the first to explore how pesticides may impact the ability of bumble bees to  forage from common wildflowers that have complex shapes such as white clover and bird’s foot trefoil. The researchers found that bumble bees exposed to environmental levels of thiamethoxam (10ppb) took longer to collect pollen than unexposed bees, as well as foraged from different flowers. Importantly, this study reports that bumble bees that were not exposed to thiamethoxam are […]

(Beyond Pesticides, March 15, 2016) Executive agencies are falling short in their efforts to protect honey bees and other wild pollinators from catastrophic declines, according to a new report from the U.S. Government Accountability Office (GAO). GAO, an investigative agency that works on behalf of the U.S. Congress, was tasked by the Senate to evaluate the progress the Environmental Protection Agency (EPA) and U.S. Department of Agriculture (USDA) have made in their actions to address the multiple threats contributing to declining managed and wild pollinators. Since 2006, U.S. beekeepers have experienced unsustainable colony die-offs, averaging over 30% each year. Concurrent declines in wild and native pollinators are also occurring, though data on the magnitude of these losses have not undergone comprehensive scientific evaluation. While a range of factors, from habitat loss, to climate change, diseases, viruses, and parasites are all contributing to these declines, independent science has identified that pesticides, specifically a new class of systemic insecticides called neonicotinoids, are the major drivers of the crisis for both managed and wild bees. In fact, some studies show that the widespread exposure to neonicotinoids increases bees’ vulnerability to diseases, viruses, and mites. The GAO report recommends a number of action items […]

(Beyond Pesticides, March 7, 2016) A United Nation’s report, released late last month, has warns the world that many species of wild bees, butterflies and other pollinators are on a dangerous path toward extinction, and that the  food supply will suffer if the causes of these declines, many of them human-made, are not stopped. The report is based on  many different scientific studies. The scientists who led the assessment pointed to pesticides as one of the leading causes of pollinator decline, specifically, a class of toxic chemicals called neonicotinoids, which adversely affect the nervous system of insects. According to their press release, the assessment,  Thematic Assessment of Pollinators, Pollination and Food Production, is the first ever issued by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem  Services (IPBES). IPBES was founded in 2012 with 124 member nations to “form a crucial intersection between international scientific understanding and public policy making.” Before its release, the assessment attracted some controversy for including two representatives from the agrochemical industry, including Bayer CropScience and Syngenta, as lead authors. Even though the IPBES requires all lead authors to complete conflict-of-interest statements, some scientists and environmentalists expressed concern. Given the roll of agrochemicals in pollinator decline, […]

(Washington, DC, March 1, 2016) After pesticide manufacturer Bayer CropScience would not voluntarily remove from the market the insecticide flubendiamide, the U.S. Environmental Protection Agency (EPA) formally issued a Notice of Intent to Cancel the insecticide, citing its high toxicity to aquatic organisms. Bayer is embroiled in controversy over its neonicotinoid insecticides because, as systemic pesticides, they move through the entire plant and express the poison through pollen and nectar, indiscriminately killing bees and other pollinators and polluting waterways. Flubendiamide, a benzenedicarboxamide pesticide, is “locally systemic” within the plant’s leaves. EPA’s action today may take years of regulatory review and legal action while the pesticide remains on the market. EPA used the controversial conditional registration provision of federal pesticide law, when in 2008 it allowed flubendiamide on the market, despite outstanding environmental data. At the time, it struck an agreement that, if unreasonable adverse effects on the environment were found, Bayer would withdraw the chemical’s registration. Today’s action serves to exemplify the consequences of allowing potentially harmful substances onto the market without all the information necessary to issue a complete finding of environmental and public safety. Because of EPA’s long cancellation process, unless it takes the rare action of finding […]

(Beyond Pesticides, February 12, 2015) A new study published last week asserts a viral epidemic driven by parasitic mites is contributing to the global decline in bees, problematically underplaying the significant impact that bee-toxic neonicotinoid insecticides have on pollinator populations, as supported by a growing body of scientific literature, especially findings that show bees’ increased vulnerability to parasites and viruses. Researchers of the study, titled “Deformed wing virus is a recent global epidemic in honeybees driven by Varroa mites” and published in the journal Science, conclude that the deformed wing virus (DWV), which is typically transmitted through its main vector, the Varroa mite, is globally distributed and recently spread from a common source, European honeybee Apis mellifera. Lead researcher Lena Bayer-Wilfert, PhD, of the University of Exeter, said European bees are at the heart of the global spread of what she calls a “double blow” for colonies. “This is clearly linked to the human movement of honey bee colonies around the globe,” she told BBC News. Co-researcher Professor Roger Butlin of the University of Sheffield said DWV was a major threat to honey bee populations across the world with the epidemic “driven by the trade and movement of honeybee colonies.” […]

(Beyond Pesticides, February 2, 2016) Boulder, Colorado’s McGuckin Hardware is setting an example for hardware stores across the country by removing bee-toxic neonicotinoids from its store shelves, and working to reorient its customers toward natural, holistic practices. McGuckin’s change is the latest in a movement among local hardware businesses to take a stand against toxic pesticides that are harmful to pollinators and unnecessary to control problem pests. “We wanted to be one of the first to get rid of them,” said Steve Wilke, McGuckins marketing communications specialist in a piece published in Hardware Retailing, a newsletter run by the North American Retail Hardware Association. Local and national advocates are praising McGuckin’s shift away from products that harm pollinators. “People are very excited about the dramatic steps McGuckin’s has taken to get neonics out of our environment,” said David Wheeler of the local pollinator-advocacy organization Bee Safe Boulder. Bee Safe Boulder is a coalition of concerned Boulder residents that successfully fought for the passage of a pollinator resolution in the City of Boulder, Layfayette, and Boulder County, Colorado. The organization also has a project aimed at encouraging local retailers to stop selling plants coated in neonicotinoids; 18 retailers in the area, […]

(Beyond Pesticides, February 1, 2016) Last Wednesday, the city council of St. Paul, MN adopted a resolution to make the city more pollinator friendly by banning bee-toxic neonicotinoids and other pesticides “proven  to be harmful to pollinators” and require an  updating of its Integrated Pest Management (IPM) program, prioritizing non-chemical methods. The resolution recognizes that its authority to restrict pesticide use on private land  has been preempted by the State of Minnesota and then directs the city to encourage property owners within its jurisdiction to practice pollinator stewardship. Under the new resolution, St. Paul has committed to: Develop or update an IPM program that requires site inspections, monitoring and prevention strategies, an evaluation on the need for pest control, and when pest control is warranted the use of structural, mechanical, biological, organic, and other nonchemical methods will be utilized first. Eliminate the use of neonicotinoid insecticides, and other pesticides proven to be harmful to pollinators, on city grounds, with specific exceptions for golf course areas and certain athletic fields. Require all city departments with any inventory of materials containing neonicotinoids, and other pesticides proven to be harmful to pollinators, to discontinue their use and properly dispose of them unless a […]

(Beyond Pesticides, January 14, 2016) Bayer CropScience, revising its stance,  has decided to concur with the  Environmental Protection Agency’s (EPA) preliminary risk assessment of neonicotinoids and acknowledge the finding of harm to honey bees in certain crops. A spokesman for Bayer CropScience said the neonic-selling giant has reviewed the assessment and found it to be “quite good and scientifically sound,” according to a news report.  The Guardian  is reporting that Bayer will be proposing new protections for pollinators, however the company has not yet announced what the new protections will be. This is a stark turnaround from  Bayer’s statement last week, which said EPA’s assessment “appears to overestimate the potential for harmful exposures in certain crops, such as citrus and cotton, while ignoring the important benefits these products provide and management practices to protect bees.” Last week, EPA released its preliminary honey bee risk assessment for one of the most widely used neonicotinoids, imidacloprid, which is  linked to severely declining honey bee populations. The assessment found  harmful residues of the insecticide  in crops where the pollinators forage  and confirmed bees’ widespread and sustained exposure to the highly toxic and persistent chemical through poisoned pollen and nectar. Imidacloprid, like the other […]

(Beyond Pesticides, January 11, 2016) Scientists at Sussex University in the United Kingdom (UK) have found that bumble bees and honey bees are exposed to a harmful chemical cocktail when collecting pollen from wildflowers and hedgerows that border neonicotinoid-treated crops in UK farmland. After testing oilseed rape croplands during blooming season, these chemical cocktails were found to be mixed with fungicides and insecticides, and at concentrations much higher than expected.  According to the Soil Association, which supported the study, “These chemical cocktails could make the impact of neonicotinoids up to 1,000 times more potent than previously realized.” With at least 121 different agrochemicals detected in hive wax and pollen samples in the Unites States, most of which include systemic pesticides, it is becoming increasingly more important to study the synergistic effects of pesticides in and outside of farm land. The study focused on “determining which mixtures of commonly used fungicides occur alongside neonicotinoids” and found that all individual oilseed rape pollen samples contained at least six neonicotinoid and fungicide residues. To compare, three neonicotinoid and six fungicides were detected in wildflower pollen samples. While the wildflower contamination was expectedly lower than crop contamination, the rate of bee contamination paints a […]

(Beyond Pesticides January 8, 2016) This week the Center for Food Safety, on behalf of several beekeepers, farmers and sustainable agriculture and conservation groups, filed a lawsuit in federal court on Wednesday  charging  the Environmental Protection Agency (EPA) with a  failure to adequately regulate neonicotinoid insecticide seed coatings used on dozens of crops throughout the U.S. The suit alleges that EPA has illegally allowed millions of pounds of coated seeds to be planted annually on more than 150 million acres  nationwide, constituting a direct violation of the registration requirements established by  the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). Absent adequate assessment of the serious ongoing environmental harms associated with coated seed use, as well as failure to require the registration of coated seeds and enforceable labels on seeds bags, this lawsuit demands immediate action to protect beekeepers, farmers and consumers from the harms associated with neonicotinoid coated seeds. Neonicotinoids are a class of insecticides that share a common mode of action that affects the central nervous system of insects, resulting in disorientation, paralysis and death. Neonicotinoid pesticides are tied to  recent pollinator declines by an ever-growing body of science. Just this week EPA released a preliminary honey bee risk […]

(Beyond Pesticides, January 7, 2016) A long-awaited U.S. Environmental Protection Agency (EPA) preliminary honey bee risk assessment, released yesterday, for one of the most widely used pesticides linked to severely declining honey bee populations confirms harmful residues of the chemical in crops where the pollinators forage, including citrus and other crops.  While EPA finds the insecticide imidacloprid, a neonicotinoid or neonic pesticide, at various levels in crops, the assessment confirms bees’ widespread and sustained exposure to the highly toxic and persistent chemical through poisoned pollen and nectar. EPA’s assessment failed to address risks posed to wild bees and widespread exposure through soil and water. [See  docket with EPA documents, for which EPA has set a 60-public comment period.] “We cannot incorporate highly toxic and persistent chemicals into virtually all agricultural crops and ornamental plants without detrimental impacts on large populations of bees, butterflies, and birds and other organisms important to a healthy ecosystem on which life depends,” said Jay Feldman, executive director of Beyond Pesticides, a science and advocacy group based in Washington, DC. “Even low level exposures to bees over vast acreage represent an unsustainable threat,” he continued. Other toxic pesticides in the neonicotinoid class of insecticides have been […]

(Beyond Pesticides, December 3, 2015) Last month, the European Commission and member states approved the new pesticide flupyradifurone. The department, known as Directorate-General for Health and Food Safety, authorized the approval of the pesticide, which is an insecticide in  the chemical class  butenolides. Bayer Crop Sciences, the creator of flupyradifurone, touts the insecticide as a “safe” alternative to neonicotinoids (neonics), although both neonics and butenolides are systemic, persistent, and acutely toxic to adult honey bees. Already launched in the United States, Mexico, Nicaragua, Guatemala, Honduras, and the Dominican Republic, advocates are pointing to the hasty nature of flupyradifurone’s approval and the lack of scientific research supporting its use. Flupyradifurone, marketed as “Sivanto prime” in Europe, is approved for use in the EU on sucking pests that feed on fruits and vegetables as well as specialty crops such as hops.  It is also approved for use in seed coatings. The chemical is neurotoxic and can inhibit nicotinic acetylcholine receptors (nAChR) in the nervous system. Neonicotinoids, widely  criticized for their harmful effects on bees,  affect the nervous system in the same way. Matthias Haas, Ph.D., Global Project Manager at Bayer CropScience says, “It combines efficacy and convenience for the grower with excellent […]

(Beyond Pesticides, November 19, 2015) French scientists say that they have found the “missing link” between laboratory studies and field studies that assess the adverse effects of neonicotinoid (neonic) insecticides on bees. The study, published in Royal Society Journal Proceedings B, evaluates the effects of neonics on honey bees in field trials. After 15 years of research into the effects of neonicotinoids on bees, researchers had identified a gap between the results of toxicity assessments on individual bees in the laboratory and  impacts seen at the colony level in the field. The new two-year study made two discoveries: First, they found that field exposure to thiamethoxam combined with imidacloprid contamination is associated with a significant excess mortality in individual free-ranging bees.  Second, while colonies appeared to be able to compensate for the excess mortality and preserve population size and honey production, this was done at the expense of a change in brood laying patterns. Thus, this study provides an explanation for the “missing link” in the discrepancies between labs studies and field studies, where the former establishes harmful and fatal effects that had yet to be replicated in real-life conditions. Because the bees responded to the increased mortality with selective […]

(Beyond Pesticides, November 19, 2015) Thanksgiving offers an opportunity for family and friends to eat, drink and be thankful for the bounty of the organic harvest. Unfortunately, conventional Thanksgiving meals are more common, which include a host of pesticides, genetically engineered foods, and can affect  the health of consumers and agricultural workers alike. Read below to find out why now, more than ever, it’s important to go organic, and how you can combat the shortcomings of conventional agriculture with an organic Thanksgiving Day feast. Now, more than ever, it’s important to go organic. The most widely used weedkiller, glyphosate, has been classified as a probable carcinogen to humans, based on laboratory animal studies. Glyphosate, produced and sold as Roundup by Monsanto, is touted as a “low toxicity” chemical and “safer” than other chemicals by EPA and industry and is widely used in food production and on lawns, gardens, parks, and children’s playing fields. However, IARC’s recent classification of glyphosate as a Group 2A “probable” carcinogen finds that glyphosate is anything but safe. According to IARC, Group 2A means that the chemical is probably carcinogenic to humans based on sufficient evidence of carcinogenicity in experimental animals. The agency also notes that […]

(Beyond Pesticides, November 16, 2015) Bayer CropScience, the manufacturer of neonicotinoid pesticides that are linked to severe decline in pollinator populations, is expected to pay fines to multiple countries in Europe for wine grape damages associated with another of its pesticides. Citing “atypical symptoms” resulting from the use of a relatively new fungicide, Bayer initially sent out a warning to wine growers to cease use of their product. Now, Bayer is collecting data and assessing how much it will offer to wine growers for the damages its product has caused. European grape growers, including vineyards in Austria, France, Germany, Italy, Luxembourg and Switzerland, have reported deformed leaves and lower yields after using Moon Privilege, also known as Luna Privilege in some markets, from the German company’s CropScience unit. In Switzerland, losses are estimated at 80 million Swiss francs ($83.73 million), as reported by marketing group Swiss Wine to Reuters. Swiss Wine’s general secretary estimates harvest losses totaling 6.65 million kilos (14 million pounds) of grapes in 2015, or about  4.85 percent of 2014’s crop. It is also estimated that wine makers have lost approximately six million bottles of wine, with  Pinot Noir grapes and Chasselas, a white wine grape, hardest […]
