(Beyond Pesticides, November 12, 2015) The U.S. Geological Survey (USGS) recently performed the first-ever study of pesticide residues on native bee populations and found that they are exposed to neonicotinoid insecticides, as well as other pesticides, at significant rates. This study digs deeper into a question  that was previously considered by a researcher who  studied chemical-intensive  apple orchards and linked a steep decline in wild or native bees to the application of pesticides. The USGS study  broadens understanding about the effects of toxic pesticides to native bee species, expanding field research that has principally focused on managed honey bee populations. The study tested for 122 different pesticides including bifenthrin, atrazine and chlorpyrifos, a chemical for which the U.S. Environmental Protection Agency (EPA) recently proposed to revoke all food tolerances in response to  a court-ordered deadline. According to study findings, 72% of bees tested positive for pesticide residues, raising concerns for the potential for unintended pesticides exposures where land uses overlap or are in proximity to one another.   Residues of pesticides found in bees in the study include  thiamethoxam, clothianidin, and imidacloprid, all of which are highly toxic neonicotinoids, a class of chemicals that have been linked to the global […]

(Beyond Pesticides, November 05, 2015) Research  at  the University of California, Davis finds  that hedgerows, a line of shrubs and trees that form a boundary at the edges of farm fields, improve a farm’s ecology and reduce the need for pesticides. Hedgerows serve many other beneficial functions; they can provide ornamental and aesthetic value, sequester carbon, and be a source of food, and more. There is also evidence that they can be an effective barrier against spray drift, reduce soil erosion, and act as habitat corridors for forest plants in agricultural landscapes.  Hedgerows support biodiversity in the face of habitat decline, given fence row to fence row cultivation practices in agriculture, manicured lawns and landscapes, urban sprawl, and the use of broad spectrum pesticides that threaten the diverse organisms that make up a healthy ecosystem. Rachael Long, M.S., a farm advisor for the UC Cooperative Extension, tells Capital Public Radio, “We have Christmas berries, and  elderberry — which has these beautiful blueberries that a lot of birds really like. We have redbud which has terrifically bright red flowers in the spring. And also ceanothus which is California lilac which has blue flowers in the spring.” She adds that birds and […]

(Beyond Pesticides, October 29, 2015) One of the top entomologists at the U.S. Department of Agriculture (USDA) filed a whistleblower complaint against a  federal agency, citing unprofessional retaliation following the publication of a study linking neonicotinoid insecticides to the decline of monarch butterflies. Jonathan Lundgren, Ph.D., Senior Research Entomologist and Lab Supervisor for the Agricultural Research Service (ARS) in South Dakota, is fighting suspension for publishing research deemed “sensitive” by his USDA superiors. According to Jeff Ruch, executive director of Public Employees for Environmental Responsibility (PEER), which is providing legal services to Dr. Lundgren, this case underscores why legal protections for government scientists are sorely needed. Until recently, Dr. Lundgren worked for USDA for eleven years with great success, and his cutting edge research has drawn national attention and international recognition. In April of this year, Dr. Lundgren published a study in The Science of Nature that shows that clothianidin, a neonicotinoid seed treatment, kills monarch butterfly larvae in the laboratory. On August 3, 2015, USDA imposed a 14-day suspension against Dr. Lundgren for submitting the Science of Nature study and for a paperwork error in his travel authorization for his invited presentation about his research to a panel of […]

(Beyond Pesticides, October 28, 2015) On the heels of a recent federal court decision that rejected the U.S. registration of sulfoxaflor, which cited inadequate and flawed review of the science on the chemical’s toxicity to bees, European beekeepers filed complaint that that asks the European Court of Justice to take the same action. The complaint  asks the court to cancel sulfoxaflor’s authorization. Sulfoxaflor is a neonicotinoid-like chemical that, like neonicotinoids, is highly toxic to bees. Three of the most widely used neonicotinoids are currently under a two-year European-wide moratorium which began December 2013, due to concerns about risks to bee populations. European beekeepers, Bee Life European Beekeeping Coordination, the Italian National Beekeeping Union (UNAAPI), and PAN Europe, filed the complaint which cites a published  negative opinion on Dow AgroScience’s sulfoxaflor by the European Food Safety Authority (EFSA). According to EFSA, the pesticide is categorized as ”˜highly toxic to bees’ and it identified crucial toxicity data gaps, which according to the beekeepers, makes a proper risk assessment for bees impossible. Despite these facts, the European Commission’s Directorate-General for Health and Food Safety (DG Sante) and the EU member states authorized sulfoxaflor in July 2015, completely bypassing the pesticide regulation, the complaint […]

(Beyond Pesticides, October 26, 2015) Last week, Pop Weaver, the second largest popcorn supplier in the country, released an official statement on its commitment to “removing 50 percent of its neonicotinoid usage in 2016, 75 percent in 2017, with a long-term commitment of further reducing usage by working with agricultural universities and those companies supplying neonicotinoids to the seed industry.” Widely-used neonicotinoids (neonics), which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies  and by beekeepers  as the major contributing factor in bee decline. This commitment is a response to a campaign led by Center for Food Safety (CFS), which asked citizens to sign a petition asking Pop Weaver, and other large popcorn suppliers, to protect bees and other pollinators by phasing out the use of neonicotinoid-coated corn seed. Over 37,000 people have signed their petition. Americans eat, on average, 17.3 billion quarts of popcorn each year; each American eats about 68 quarts. According to CFS, there are roughly 40 insecticides currently registered for use as an active chemical on popcorn, including 3 bee-toxic neonicotinoid chemicals: clothianidin, thiamethoxam, and imidacloprid. Between  79 and 100 […]

(Beyond Pesticides, October 22, 2015) With increasing consumer concern about genetically engineered (GE) food, yesterday  the U.S. Senate Committee on Agriculture, Nutrition, and Forestry held a hearing,  entitled Agriculture Biotechnology: a Look at Federal Regulation and Stakeholder Perspectives, that critics called lopsided. Most witnesses characterized GE food as safe or side-stepped the issue of safety, as government witnesses refused to distinguish GE from conventional food and opposed food labeling. “This is the first time in 10 years we’ve had a hearing on biotech. I guess we’re a little late, but we’re here,” said chair of the committee, Senator Pat Roberts (R-KS). The ranking  minority member of the committee, Senator  Debbie Stabenow (D-MI)  said,  “Biotechnology is proven to be safe, beneficial, and I believe will play a major role in helping to solve these dual global challenges of climate change and global food security,” Central to the hearing is the the issue of labeling food products containing GE crops. Senator Stabenow called for the adoption of legislation on GE food labeling, presumably with language that will preempt the authority of states to adopt more stringent labeling standards. Senator Stabenow said that she wants labeling that “doesn’t stigmatize biotechnology.” The GE food […]

(Beyond Pesticides, October 20, 2015) Exposure to neonicotinoid (neonic) pesticides results in profound negative impacts to the health of honey bee queens, according to an international team of researchers led by Geoff Williams, MD, PhD, at the University of Bern in Switzerland. While most studies to date have investigated how neonics effect the health of individual workers or overall colony fitness, Dr. William’s study, Neonicotinoid pesticides severely affect honey bee queens, is one of the first to focus on the health of honey bee queens. Neither the European Union nor U.S. Environmental Protection Agency (EPA) study the impacts of pesticides on queen health before allowing a pesticide to market. The results of this research are particularly concerning, given widespread anecdotal evidence from beekeepers across the globe that ”˜poor quality queens’ are playing a role in bee declines. To test the impacts of these chemicals on queen honey bees, scientists exposed a sample of 29 queens to field-realistic levels of the neonics  clothianidian and thiamethoxam (1 parts per billion and 4 ppb respectively), and compared them to a population of 28 control queens, which were not treated with neonics. Both groups experienced similar environmental circumstances in terms of food availability, rearing […]

(Beyond Pesticides, October 15, 2015) A new study, published in Environmental Science & Technology, has found that wildflowers bordering fields that are treated with neonicotinoids contain a higher concentration of the bee-toxic pesticides than the actual treated fields, pointing out an often overlooked avenue of exposure for bees. Widely-used neonicotinoids, which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies  and by beekeepers  as the major contributing factor in bee decline. The study, titled Neonicotinoid Residues in Wildflowers, A Potential Route of Chronic Exposure for Bees, discovered neonicotinoid insecticides in wildflowers, including Hogweed and Poppy pollen (up to 86ppb and 64ppb, respectively). The study’s authors  found higher concentrations of neonicotinoids in wild flowers in field margins than in Oilseed rape flowers in the adjacent neonicotinoid treated crop — on average 15ppb vs. 3ppb.   They also found that more than 97% of the neonicotinoids being brought into the hive by honey bees are from wildflowers, while only 3% are  from the crop. Researchers have found  that chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee. In other words, these pesticides […]

(Beyond Pesticides, September 25, 2015) Neonicotinoid-treated seeds do not reduce crop damage from pests, adding to a growing body of evidence questioning the benefits of using these bee-toxic insecticides, according to a study  published in the journal BioOne. Widely-used neonicotinoids (neonics), which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies and by beekeepers  as the major contributing factor in bee decline. The study,  titled Impact of Western Bean Cutworm (Lepidoptera: Noctuidae) Infestation and Insecticide Treatments on Damage and Marketable Yield of Michigan Dry Beans, examines the relationship between western bean cutworm infestation and damage in dry beans, and the use of seeds treated with the neonicotinoid thiamethoxam, as well as soil treated with aldicarb, another systemic insecticide. Researchers have concluded that neither thiamethoxam nor aldicarb reduced cutworm damage. In fact, plots treated with these insecticides had a higher percentage of defects due to feeding by pests when compared to untreated plots, which researchers believed is  attributable to factors such as fewer natural enemies. There have been additional reports and studies published over the past few years questioning the benefits of neonic use. In […]

(Beyond Pesticides, September 18, 2015) Glyphosate’s harmful effects continue to accumulate, this time with evidence pointing to toxic and sublethal effects on bees. According to a new study conducted by German and Argentinian researchers, honey bees exposed to low levels of glyphosate have a hard time returning home. Glyphosate, the  controversial and toxic active ingredient in Monsanto’s Roundup, is an herbicide widely used on genetically-engineered (GE) crops as well as on parks and golf courses, for control of weeds and grasses. Along with neonicotinoids, which have been linked to worldwide bee decline by a growing body of science, glyphosate is just another chemical in the toxic mixture that bees and other non-target organisms are constantly exposed to in the environment. In the study, titled “Effects of sublethal doses of glyphosate on honeybee navigation” and published in the Journal of Experimental Biology, researchers evaluate the effects of recommended concentrations of glyphosate used in agricultural settings on honey bee navigation and found that a single exposure to a concentration of glyphosate within this range delays the return of the foraging honey bee to the hive. Flight trajectories were also affected after successive exposure to the herbicide, suggesting that the spatial learning process […]

(Beyond Pesticides, September 16, 2015) In a letter posted to the federal docket, the U.S. Department of Agriculture (USDA) states that it is opposed to U.S. Environmental Protection Agency’s (EPA) recent proposal to restrict pesticides highly toxic to bees on sites where managed bees are present, saying the measure “has not established the need for such a prohibition.” In its position, USDA  cites economic impacts to farmers and lack of a cost/benefit analysis. USDA’s critique of EPA’s proposal contrasts with a decision handed down last week by a federal court that ruled EPA should not ignore risk concerns for bees and rejected the registration of a pesticide known to be highly toxic to bees, highlighting a lack of collaboration and understanding between federal agencies in advancing  pollinator protection. USDA communicated its challenge to EPA despite the growing body of science on the hazards of neonicotinoid insecticides and findings in Europe that their restriction does not undermine crop productivity. Last May,  EPA announced a new proposal  to temporarily prohibit foliar applications of pesticides that are acutely toxic to bees during plant bloom and when managed bees are on site and under contract. The proposal received a mixed response, with many from […]

(Beyond Pesticides, September 11, 2015) On Thursday, the Ninth Circuit Court of Appeals unequivocally rejected the U.S. Environmental Protection Agency’s (EPA) unconditional registration of the systemic and bee-toxic pesticide sulfoxaflor. The Court concluded that EPA violated federal law and its own regulations when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide would have on honey bee colonies. The Court vacated EPA’s unconditional registration of the chemical, meaning that sulfoxaflor may no longer be used in the U.S. However, while the decision is good news for now, it still leaves the door open for sulfoxaflor’s future use once EPA obtains the necessary information regarding impacts to honey bees and re-approves the insecticide in accordance with law. The case is Pollinator Stewardship Council, American Honey Producers Association, National Honey Bee Advisory Board, American Beekeeping Federation, Thomas Smith, Bret Adee, Jeff Anderson v. U.S. EPA (9th Circuit U.S. Court of Appeals,  No. 13-7234). Dow AgroSciences (a Dow Chemical company)  joined  the case as an intervenor to support EPA. EPA initially proposed to conditionally register sulfoxaflor and requested additional studies to address gaps in the data regarding the pesticide’s effects on bees. A few months later, however, EPA unconditionally registered […]

(Beyond Pesticides, September 10, 2015) Last week, California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced that it intended to list glyphosate (Roundup) and three other chemicals as cancer-causing chemicals under California’s  Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Glyphosate  is a phosphanoglycine herbicide that inhibits an enzyme essential to plant growth. Under California law, Proposition 65 requires that certain substances identified by the International View postAgency for Research on Cancer (IARC) be listed as known cancer-causing chemicals. In March, a study by the IARC classified glyphosate as a Group 2A material, which means that the chemical is carcinogenic based on sufficient evidence of carcinogenicity in experimental animals. The agency considered the findings from an EPA Scientific Advisory Panel report, along with several recent studies in making its conclusion. However, industry supporters of glyphosate all over the globe are conducting their own studies to attempt to prove that it is not a carcinogen. These studies, like one by German Federal Institute for Risk Assessments (BfR), are based almost solely on industry science and classified industry reports, each of which might not consider critical variables. With more glyphosate-focused studies being released, the growing evidence […]

(Beyond Pesticides, September 4, 2015) Research into neonicotinoid insecticides, a class of bee-toxic chemicals, and their effects on bees, needs to be more comprehensive in order to better reflect their global use, concludes a recent review of the current literature. The authors of the review state that despite considerable research efforts, there are still significant knowledge gaps concerning the impacts of neonicotinoids on bees. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have experienced ongoing and rapid population declines. The science has become increasingly clear that pesticides (especially the  neonicotinoid class of insecticides), either acting individually or synergistically, play a critical role in the ongoing decline of honey bees and wild pollinators. Neonicotinoids can be persistent in the environment, and have the ability to translocate into the pollen and nectar of treated plants. The systematic review, titled Neonicotinoid Insecticides and Their Impacts on Bees: A Systematic Review of Research Approaches and Identification of Knowledge Gaps  and published in the journal PLoS ONE, took a look at over 200 primary research studies in order to identify knowledge gaps. While there is a growing body of science examining the impacts of neonicotinoid use, knowledge gaps need […]

(Beyond Pesticides, August 28, 2015) The European Union’s food safety agency confirmed Wednesday that foliar spraying of neonicotinoids (neonics), the widely-used bee-toxic insecticides, poses a risk to bees, bolstering previous research that led to a two-year moratorium on the chemicals in the EU. The European Food Safety Authority (EFSA), which guides EU policymakers, said leaf spray containing three neonicotinoid pesticides — clothianidin, imidacloprid, and thiamethoxam — could harm bees. Previous research found that these chemicals pose a risk as seed treatments or granules, which prompted the European Commission to limit their use in  December 1, 2013. The use of the three neonicotinoid substances in seed or soil treatments is prohibited in the European Union for crops attractive to bees and for cereals other than winter cereals except in greenhouses. “They (the EFSA conclusions) confirm that the Commission was correct to take precautionary measures in 2013,” a Brussels-based EU executive said in a statement. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and pollinator decline. Recently, a  study  performed by the Food and Environment Research Agency (FERA) in the United Kingdom provides evidence confirming the link between neonicotinoid pesticides and continually increasing […]

(Beyond Pesticides, August 26, 2015) A  study performed by the Food and Environment Research Agency (FERA) in the United Kingdom (UK) provides evidence of confirming the link between neonicotinoid pesticides and continually increasing honey bee colony losses on a landscape level. The study, Evidence for pollinator cost and farming benefits of neonicotinoid seed coatings on oilseed rape, was published in the Nature journal Scientific Reports. This is a significant study, as the UK government has always maintained that neonicotinoid pesticides do not threaten bees, and that honey bee losses are instead caused by the parasitic varroa mite, siding with industry arguments that pesticides are safe when used properly. However, this new study indicates otherwise, confirming a direct link between neonicotinoids and honey bee colony losses at a nationwide level. This study distinguishes itself from  a previous study in the U.S. that extrapolated real world neonicotinoid exposure levels  to  test hives by analyzing actual fields in a  long-term assessment. To a large degree, the new study addresses industry critics of the earlier study design who have tried to discount previous findings of bee decline associated with neonicotinoid use (see Beyond Pesticides’ Sowing the Seeds of Doubt, which addresses these industry myths). […]

(Beyond Pesticides, August 25, 2015) Last Friday, the City Council of Minneapolis, MN unanimously passed a resolution declaring Minneapolis a pollinator-friendly community and urging city residents to take steps to protect dwindling pollinator populations. A groundswell of public support from a wide range of local and national groups, including Beyond Pesticides, resulted in swift passage of the resolution, the latest in a long string of local government action to safeguard pollinators from harmful pesticides, as federal proposals fail to address the magnitude of the crisis. “With the passage of today’s resolution, Minneapolis is now doing its part in the global effort to protect and grow the pollinator populations,” Mayor Betsy Hodges said to CBS Minnesota. The resolution, introduced and written by Councilmember Cam Gordon, assigns a number of bee safe actions to various city departments. While the Health Department’s Environmental Services Unit will maintain a list of pollinator-friendly plants, the Community Planning and Economic Development Department and Property Services Division of the City Coordinator’s office will create habitat for local pollinators. The Minneapolis Public Works Department will pursue both increased bee habitat and adopt clear guidelines against the use of pesticides, including but not limited to systemic neonicotinoid  (“neonic”) insecticides, […]

(Beyond Pesticides, August 21, 2015) Neonicotinoid insecticides contaminate over half of urban and agricultural streams across the United States and Puerto Rico, according to a study released earlier this week by the U.S. Geographical Survey (USGS). Neonicotinoids (neonics) are bee-toxic insecticides that have been linked to the global decline in bee populations by a large body of science. The study, titled “First national-scale reconnaissance of neonicotinoid insecticides in streams across the USA” and published in Environmental Chemistry,  was conducted from 2011 to 2014 and spans 24 states and Puerto Rico. Researchers found that at least one of the six neonicotinoids tested by USGS researchers was found in more than half of the sampled streams. Detections of the  six  neonicotinoids varied:    imidacloprid  was found in 37 percent of the samples in the national study, clothianidin in 24 percent, thiamethoxam in 21 percent, dinotefuran in 13 percent, acetamiprid in 3 percent, and thiacloprid was not detected. Both urban and agricultural uses contributed to neonic concentrations in streams, with imidacloprid occurrence significantly related to the amount of urban land-use and clothianidin and thiamethoxam significantly related to the amount of cultivated crop. “In the study, neonicotinoids occurred throughout the year in urban streams […]

(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, August 12 2015) Last week, the City of Plattsburgh, New York, unanimously approved a policy that encourages city departments and city residents to reduce and eventually eliminate their use of toxic pesticides, such as neonicotinoids and glyphosate. In the same resolution, city residents and department heads are also encouraged to refrain from genetically modified organism (GMO) cultivation, though they recognize there is very little of that taking place within Plattsburgh city limits. While this policy can only be used to discourage the use of pesticides and GMOs, not implement an outright ban, due to preemptive New York state law that occupies the field of pesticide regulation, city officials are hopeful that they will be able to use their influence to implore the state of New York and U.S. legislators to take statewide and nationwide measures on the production of GMO crops and to curb the use of toxic pesticides. The language of the resolution, sponsored by Councilman Mike Kelly, cites the health of honey bees and other insects as one of the main reasons for encouraging citizens to refrain from the use of pesticides in the practice of lawn care and beautification. It also specifically names neonicotinoids as […]

(Beyond Pesticides, August 5, 2015) The United Kingdom (UK) is poised to harvest higher than expected yields of winter oilseed rape (canola) in its first neonicotinoid-free growing season since the European moratorium on neonicotinoids went into place in 2013. This bumper harvest comes amid the recent approval of an emergency exemption for neonicotinoid use on the crop in certain areas of the UK, and disproves the industry argument  that  the crop would falter without the use of neonicotinoids. Activists argue that these findings show there is ”˜no emergency’ for neonicotinoid use and that the current moratorium should remain in effect. The first harvest results of winter oilseed rape (canola) planted without neonicotinoid seed treatments have come in – and farmers are experiencing a better than usual crop. Figures for the first oilseed rape harvest since the European-wide ban on neonicotinoid pesticides was introduced show that the yield so far is higher than the average for the previous decade, when the chemicals were used on the majority of oilseed rape grown in the UK. Farmers Weekly, a leading multimedia information service for farmers and agricultural businesses, has reported that yields are up by as much as eight percent. The European Union […]

(Beyond Pesticides, August 4, 2015) Nearly every food available for purchase at the U.S. Congressional Dining Hall contains detectable levels of neonicotinoids (neonics), chemical insecticides implicated in the global decline of wild and managed pollinators. The results of a new study, performed by the American Bird Conservancy (ABC) and the Harvard T.H. Chan School of Public Health, reveals how reliance on these toxic chemicals can both directly and indirectly affect  our food supply. Authors of the study hope the results will build Congressional support for the Saving America’s Pollinators Act of 2015, which would suspend the use of neonics while an independent review analyzes the chemical’s effects to birds, pollinators, and other wildlife. Researchers for the study conducted two rounds of food testing, the first in January, and the second in May 2015. Approximately half of samples were taken from the House Longworth Cafeteria and half from Senate Dirksen Cafeteria in Washington, D.C. In total, 66 food samples were tested for the presence of neonicotinoids. Of that, 60, or 91% of samples tested positive for one neonic, and 47, or 71% of samples had two or more neonics present. “We were surprised to find that most foods contained multiple neonicotinoids, […]
