Neonicotinoid Insecticides Found to Disrupt Insects’ Vision and Flying Ability

(Beyond Pesticides, April 19, 2019) Flying insects exposed to neonicotinoid insecticides or its breakdown products experience visual impairment and difficulty flying, according to a study published in the journal NeuroToxicology by researchers at the University of Saskatchewan, Canada. While at face value these impacts may sound non-lethal, any loss of fitness in the wild can make flying insects an easier meal for their predators. “Our findings suggest that very low doses of the pesticide or its metabolic products can profoundly and negatively affect motion detection systems that flying insects, such as locusts, grasshoppers and bees, need for survival,” said Jack Gray, PhD, an expert in neural control of animal behavior at the University of Saskatchewan. Researchers used locusts as proxies for other flying insects, as the visual processing in their brains is easy to track in laboratory settings. Moreover, as study co-author Rachel Parkinson notes, “Bees and other flying insects use similar neural mechanisms to process visual motion,” making the implications of this study applicable to a wide range of other airborne insects. And rather than simply focus on the effects of exposure to a single active ingredient, researchers also studied whether its breakdown products (metabolites) resulted in similar impairment. […]

Fish and Wildlife Service Sued for Failure to Disclose Use of Bee-Toxic Pesticides and GMO Crops in Wildlife Refuges

(Beyond Pesticides, April 12, 2019) The Center for Biological Diversity (CBD) announced on April 3 that it is suing the U.S. Fish and Wildlife Service (FWS) for its failure to release public records, despite multiple FOIA (Freedom of Information Act) requests, that would reveal on-the-ground impacts of FWS allowing use of neonicotinoids and genetically engineered (GE) crops in wildlife refuges. Last August, in yet another rollback of protections for wildlife, the environment, and public health, the Trump administration reversed a 2014 FWS decision to ban the use of neonicotinoids and GE crops in National Wildlife Refuges. If successful, the CBE lawsuit, filed in U.S. District Court for the District of Columbia, would compel the agency to provide the requested documents. This would allow the public, largely through the work of NGO (non-governmental organization) watchdogs, such as CBD and Beyond Pesticides, to understand what harms are being caused on the nation’s protected public lands by the administration’s reversal of the 2014 ban. Hannah Connor, a CBD senior attorney, said, “The goal of the lawsuit is to get them to comply with the Freedom of Information Act and produce the records that have been requested. . . . We aren’t asking them to […]

Take Action: Help Stop Pesticide-Treated Seeds from Poisoning the Environment

(Beyond Pesticides, March 25, 2019) EPA is using a regulatory loophole – the “treated articles exemption” – to allow systemic insecticides to be used in mass quantities, without regulating or labeling them as required under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). EPA does not currently assess adverse effects on the environment and public health caused by widespread use of neonicotinoid insecticides delivered through seeds coated with the insecticides, resulting in widespread exposure to one of the most environmentally damaging classes of chemicals on the market. Tell your Congressional delegation that EPA must fully regulate treated seeds to protect the environment and public health. Pesticide-coated seeds are now ubiquitous, yet their far-reaching impacts on wildlife and human health continue to go unregulated. The introduction and spread of seed-delivered pesticides to major field crops, beginning around 2003, caused a massive increase in total neonicotinoid use nationwide. As of 2011, 34 to 44% of soybeans and 79 to 100% of maize acres were planted with coated seeds, accounting for an astounding 35-fold increase in nationwide neonicotinoid use from baseline rates prior to 2003 (Douglas and Tooker, 2015). Alarmingly, because the national pesticide survey conducted by the National Agricultural Statistics Service fails to […]

Study Finds that Commonly Occurring Levels of Neonicotinoid Insecticide Harm White-tailed Deer

(Beyond Pesticides, March 22, 2019) A two-year study, published March 14,  finds that field-relevant contamination with the neonicotinoid insecticide imidacloprid causes reduced body weight and metabolism in white-tailed deer, and – in fawns – mortality. Remarkably, researchers uncovered imidacloprid levels in free-ranging deer a full 3.5 times higher, on average, than the levels in the animals treated in their experiment. These new findings add to the mounting evidence of the hazards posed by current patterns of neonicotinoid use, while evidence of benefits remains sparse. The study, published in Nature Scientific Reports, includes two years of data on the physiological and behavioral outcomes of imidacloprid contamination in 80 white-tailed deer housed in a South Dakota State University captive research facility. Notably, researchers were unable to entirely control imidacloprid levels in untreated deer, most likely due to background contamination from corn- and soy-based feed, and surrounding vegetation infiltrated by runoff from nearby agricultural fields. This background contamination altered, but did not compromise, the analysis. Researchers found that imidacloprid levels detected in the spleens of treated and control animals were significantly predictive of reduced thyroid hormone levels, shorter jawbones, lower activity levels, and higher fawn mortality. Lead authors Elise Berheim, Jonathan Jenks, PhD, […]

Not Just Bumble and Honey: Ground Nesting Bees Impaired by Neonicotinoid Exposure

(Beyond Pesticides, March 19, 2019) Research is beginning to explain how systemic neonicotinoid insecticides affect often overlooked species of ground nesting bees. While much of the current scientific literature has focused on the impacts of pesticides to bumblebees and honey bees, a study, Chronic contact with realistic soil concentrations of imidacloprid affects the mass, immature development speed, and adult longevity of solitary bees, recently published in Scientific Reports, confirms that wild, soil-dwelling bees are at similar risk. As policy makers consider ways to protect pollinators, this research finds that uncontaminated soil is an important aspect of ensuring the health of wild, native bees. “This is an important piece of work because it’s one of the first studies to look at realistic concentrations of pesticides that you would find in the soil as a route of exposure for bees,” said Nick Anderson, co-author of the study. “It’s a very under-explored route, especially for some of the more solitary species that nest in the ground.” In order to study the impact of neonicotinoids on ground nesting bees, researchers used orchard mason bees and leafcutter bees as proxies, as they are easier to gather and rear in the lab, and have a similar ecology […]

Pesticide Exposure Alters Gene Expression in Bumblebees

(Beyond Pesticides, March 13, 2019) A study on the impact of two neonicotinoid pesticides shows differential gene expression in bumblebees (Bombus terrestris) after exposure. Considering the current worldwide plight of insects, the authors of point to the cutting edge research as both a reason and a methodology to more carefully examine the effects of pesticides. “Caste- and pesticide-specific effects of neonicotinoid pesticide exposure on gene expression in bumblebees” was published in the journal Molecular Ecology in early March. Researchers fed variable colonies with clothianidin or imidacloprid-laced sucrose. They analyzed gene expression in the heads of worker bumblebees and colony queens using RNA sequencing (RNA-seq), inspired by biomedical techniques. This approach allowed for new insight on what genes and pathways are affected by neonicotinoid exposure. Study author Yannick Wurm, PhD, stated in a press release, “Our work demonstrates that the type of high-resolution molecular approach that has changed the way human diseases are researched and diagnosed, can also be applied to beneficial pollinators. This approach provides an unprecedented view of how bees are being affected by pesticides and works at large scale. It can fundamentally improve how we evaluate the toxicity of chemicals we put into nature.” Clothianidin had a stronger […]

Bee-Toxic Neonicotinoid Insecticide Exposure Linked to Hormone-Dependent Breast Cancer

(Beyond Pesticides, March 7, 2019) A publication in the journal Environmental Health Perspectives highlights findings from a recent study showing that environmental concentrations of the neonicotinoid insecticides thiacloprid and imidacloprid increase expression of a gene linked to hormone-dependent breast cancer. Authors of the featured study uncovered a pathway through which neonicotinoids stimulate excess estrogen production, known to occur during the development of progressive hormone-dependent breast cancer. In the words of the authors, “Our findings highlight the need for further research to assess the potential impacts of low-dose and chronic exposure to neonicotinoids on endocrine processes affecting women’s health.” The study, published in Environmental Health Perspectives in April 2018 by researchers at the University of Quebec, is not the first to point to a potential link between neonicotinoid exposure and breast cancer. A 2015 study by the same research group revealed that the neonicotinoids thiacloprid and thiamethoxam, along with the herbicide atrazine, induce similar effects in breast cancer cells. In both studies, exposure to neonicotinoids alter promoter activity to induce heightened production of the enzyme aromatase, which is known to stimulate estrogen production and thereby cancer cell proliferation. The recently published study, authored by Silke Schmidt, PhD, brings greater urgency to […]

Take Action: Saving America’s Pollinators Act Reintroduced in Congress

(Beyond Pesticides, March 4, 2019) Last week, U.S. Representative Earl Blumenauer (D-OR) reintroduced the Saving America’s Pollinators Act (H.R.1337) to cancel specific bee-toxic pesticides and establish a review and cancellation process for all pesticides that are potentially harmful to pollinators. The specific pesticides targeted in the bill include the systemic insecticides imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, sulfoxaflor, flupyradifurone, and fipronil. The bill also establishes requirements for review of other potentially bee-toxic chemicals by an independent pollinator protection board, and requires annual reports on the health and population status of pollinators. The bill creates a sustainable model for pollinator protection in the face of ongoing obstruction by an increasingly industry-influenced EPA. There are 29 cosponsors to date. The current bill is the fifth version of Saving America’s Pollinators Act (SAPA), which was first introduced by U.S. Representative Conyers (D-MI) in 2013. The newest version differs from previous bills in its bold definition of who should have responsibility for assessing harm to pollinators. SAPA 2019 calls for the establishment of a Pollinator Protection Board, to be composed of expert scientists, beekeepers, farmers, members of environmental organizations and other key stakeholders, nearly all of whom must not have any conflict of interest or affiliation […]

Take Action: Ask the Largest Food Retailer to Lead the Way and Stop Selling Food Grown with Pesticides

(Beyond Pesticides, February 26, 2019) Breakfast cereal, apples, applesauce and pinto beans made and sold by Kroger contain residues of toxic pesticides linked to a range of series health and environmental problems, according to a residue study by Friends of the Earth. This is alarming. Kid-friendly food like applesauce and Cheerios should not contain dangerous pesticides. Kids are the most vulnerable to these pesticides and shouldn’t be exposed to brain-damaging or cancer-causing pesticides when they eat their breakfast or snacks. The connection between pesticides and cancer, learning disabilities, and other diseases is supported by hundreds of studies in Beyond Pesticides’ Pesticide-Induced Diseases Database. These new tests, which corroborate numerous residue studies, mean that Kroger customers may be purchasing food with the intent of providing safe and healthy food for their families, but end up unknowingly exposing them to toxic pesticides. Join the national week of action by either delivering a letter to Kroger in person, or sending an email to Kroger Chief Executive Rodney McMullen. The pesticides found in Kroger’s food are harmful to human health and pollinators. Friends of the Earth found residues of cancer-causing glyphosate, brain-damaging organophosphates, and bee-killing neonicotinoid pesticides. Organophosphates can cause damage to children’s developing brains, including reduced IQ, loss […]

Adding to Residue Studies, Report Documents Toxic Pesticides in Common Foods Sold by Major Retailers

(Beyond Pesticides, February 13, 2019) Friends of the Earth (FOE) released a report last week again showing pesticide residues in the food supply. The report, Toxic Secret, found store and name brand foods produced and sold by the top four U.S. food retailers — Kroger (NYSE:KR), Walmart (NYSE: WMT), Costco (NYSE:COST) and Albertsons — contain residues of toxic pesticides linked to a range of serious health and environmental problems. Among the pesticides found is the herbicide glyphosate, confirming residue testing results found in numerous studies. Glyphosate, the active ingredient in Roundup, has has been detected in popular foods, including “100% pure” honey, Doritos, Oreos, Goldfish, Ritz Crackers, German beers, California wines, and UK bread. Glyphosate has been ranked as potentially cancer causing in humans and adversely affects the human gut microbiome. See Residue Testing Find More Glyphosate in Popular Cereals. The FOE study finds that oat cereals, apples, applesauce, spinach and pinto beans at the retailers contained detectable amounts of glyphosate, organophosphates and neonicotinoids. The average level of glyphosate found in cereal samples (360 parts per billion) was more than twice the level set by scientists at Environmental Working Group for lifetime cancer risk for children. The average level of glyphosate found in pinto beans (509 ppb) was more […]

Study Finds State Pollinator Protections Fall Short

(Beyond Pesticides, February 7, 2019) A new study, released in Environmental Science and Policy, systematically reviews all state-level pollinator protection acts passed since 2000 and makes a somewhat dim diagnosis: as a rule, state policies fall far below the mark for protecting invaluable ecosystem services and ensuring long-term, sustainable food production. Authors judge the legislation against a set of pollinator protection policy benchmarks established in 2016 by a group of scientists from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Citing the ten policy recommendations laid out by IPBES experts, researchers point to the failure of all enacted state policies to address three main target areas – (1) to improve genetically modified crop risk assessment, (2) to incentivize farmers to make the switch from agrochemical dependence to sustainable benefits from ecosystem services, and, critically, (3) to support diversified farming systems. Beyond Pesticides notes one additional missed target: (4) funding for research on organic, diversified, and ecologically intensified farming. The study includes a total of 109 state laws passed from 2000 to 2017, which authors tracked down by searching usa.gov and state legislative websites and by submitting requests to state librarians. To uncover common themes and patterns among these […]

Western Monarchs Experience Catastrophic Declines Over the Last Year

(Beyond Pesticides, January 16, 2019) Preliminary counts in California indicate the western monarch butterfly population dropped 86% from 2017 to 2018. The survey is a result of an annual effort by volunteer citizen scientists, organized by the nonprofit organization Xerces Society. If the trend from the initial sample (97 sites) holds true, the population of overwintering butterflies is estimated to be less than 30,000 – 0.05% of its historical size. Full and vetted results will be published in late January. To get an accurate count of monarch populations, volunteers follow a monitoring guide, which recommends beginning a count on a still, cool, and dry morning so that monarchs are still clustered together. Volunteers count a small cluster of monarchs and then extrapolate that number to arrive at a total for the larger cluster they’re observing. Citizen science has been crucial to understanding the decline of monarchs and insects worldwide. As covered by The New York Times, the current “Insect Apocalypse” has largely been documented by volunteers. The dismal numbers recorded this year are potentially disastrous, as the predicted extinction threshold for overwintering western monarchs is a population of 30,000. However this threshold, based on population densities needed for thermoregulation and mating […]

Settlement Bans Some Bee-Toxic Pesticides, Requires Public Comment Period on Testing All Pesticide Product Ingredients and Regulating Pesticide-Treated Seeds

(Beyond Pesticides, January 4, 2019) First, the good news: plaintiffs in a 2013 lawsuit against the Environmental Protection Agency (EPA) can allow themselves a small victory dance. In that suit, plaintiffs made a number of claims related to EPA’s failure to protect pollinators from dangerous pesticides, its poor oversight of the bee-killing pesticides clothianidin and thiamethoxam, and its practice of “conditional registration,” as well as labeling deficiencies. The parties in the suit negotiated a settlement, as directed by a federal judge (see below), that was signed in October 2018 and portends some positive movement in curtailing the use of some toxic pesticides [12 products, each of which contains chlothianidin or thiamathoxam as an active ingredient] that harm pollinators in particular, as well as other organisms and the environment. It also establishes a public process for EPA to consider requiring whole formulations of pesticide products during registration, and redefining EPA’s interpretation of law that allows seeds treated with bee-toxic pesticides to escape regulation as a pesticide. The suit was brought by a number of individual beekeepers and several organizations, including Beyond Pesticides, Center for Food Safety (CFS), Sierra Club, and Center for Environmental Health, and named as defendants Steven Bradbury, then-director of the […]

Take Action: Protect Biodiversity – Reinstate the Ban of Bee-Toxic Neonicotinoid Pesticides on Wildlife Refuges

(Beyond Pesticides, December 3, 2018) In August 2018, the Trump administration announced a reversal of a 2014 U.S. Fish and Wildlife (FWS) decision to ban neonicotinoid insecticides on National Wildlife Refuges. The administration’s action threatens not only pollinators, but contributes to the attack on biodiversity worldwide.  Tell Congress to protect biodiversity by insisting that the ban on neonicotinoid pesticides in wildlife refuges be reinstated. In 2014, FWS announced that all National Wildlife Refuges would join in the phase-out of neonics (while also phasing out genetically engineered crops) by January 2016. FWS “determined that prophylactic use, such as a seed treatment, of the neonicotinoid pesticides that can distribute systemically in a plant and can potentially affect a broad spectrum of non-target species is not consistent with Service policy. We make this decision based on a precautionary approach to our wildlife management practices and not on agricultural practices.” This move was not only intended to protect honey bees that have suffered average losses above 30% since 2006, but also the federally threatened and endangered pollinators that live in National Wildlife Refuges. However, it is not just pollinators who are affected. Recent research has found dramatic drops in overall insect abundance, leading entomologists to speak of an “insect apocalypse.” Various studies have found reductions of up to […]

Behavioral Effects in Bumblebees Linked to Neonicotinoid Insecticides

(Beyond Pesticides, November 28, 2018) Recent research out of Harvard University and published in the journal Science has demonstrated some of the mechanisms through which exposures to neonicotinoid pesticides harm bumblebee populations. The study found that exposure to imidacloprid, a neonicotinoid — the most widely used category of pesticides worldwide — directly impacts social behaviors in bumblebees. These behaviors have serious effects on the functioning and viability of bee colonies. In the research experiment, worker bees exposed to imidacloprid exhibited reduced general and nurturant activity, and a tendency to locate themselves at the periphery of the nest. The study noted decreased caretaking and nursing behaviors, which in turn harms productivity and thermal regulation in the colony. These tasks are important to colony development; impaired thermoregulation negatively affected the bees’ typical construction of an insulating wax canopy for the nest, and poor caretaking can affect brood growth. Investigators noted that, “Neonicotinoids induce widespread disruption of within-nest worker behavior that may conribute to impaired growth. . . . These changes in behavior acted together to decrease colony viability, even when exposure was nonlethal.” The authors also observed that many of these dysregulated behaviors were more pronounced at night than during sunlight hours, and […]

Neonicotinoids Found to Change Frog Behavior

(Beyond Pesticides, November 15, 2018) Neonicotinoids are widely known for their link to declining pollinator populations, but new research finds that the ill effects of these chemicals also extends to amphibian populations. In a study published late last month, scientists from the National Wildlife Research Center in Ottawa, Canada found that chronic exposure to real-world levels of the neonicotinoid imidacloprid limits the ability of juvenile wood frogs to escape a predator attack. This research adds additional evidence that neonicotinoids are harming aquatic food chains, and reinforces calls for U.S. regulators to follow the science and adequately restrict these toxic pesticides. Researchers investigated the impact of neonicotinoids on the post-tadpole life stage of wood frogs, which has been identified as critical to sustaining viable populations of the species. Rather than determine acute impacts that assess how lethal a pesticide is, scientists opted to observe how wood frog behavior changes as a result of chronic, real-world exposure scenarios. In particular, scientists sought to figure out whether exposure resulted in an altered behavioral response to the presence of a predator. As tadpoles, wood frogs were chronically exposed to real world levels of imidacloprid (1, 10, and 100 micrograms/liter), while others were left unexposed […]

Take Action: Tell Kroger to Stop Selling Food Grown with Toxic Pesticides

(Beyond Pesticides, October 15, 2018) As a leader in organic sales, it is critical that Kroger take additional expedited steps to increase the market share of organic food and eliminate the use of toxic pesticides harmful to public health and the environment. Kroger is among the major food retailers that sells food that has been grown with toxic pesticides, such as the extremely hazardous insecticide chlorpyrifos which causes neurological and brain damage in children. Kroger should immediately end its misleading and fraudulent advertising and labeling of food products as “natural” and replace these with certified organic products. In fact, by misleading consumers with “natural” labeling and advertising of food, Kroger supports chemical-intensive agriculture that poisons children, causes cancer, and threatens biodiversity through the use of toxic chemicals like chlorpyrifos, glyphosate, and neonicotinoids. This is unnecessary and unacceptable. Tell Kroger to stop selling food grown with toxic pesticides. Chlorpyrifos  is a highly neurotoxic organophosphate pesticide that is linked to neurologic developmental disorders in children. Exposure to even low levels of organophosphates like chlorpyrifos during pregnancy impairs learning, changes brain function, and alters thyroid levels of offspring into adulthood. EPA’s own assessment finds that children exposed to high levels of chlorpyrifos have developmental delays, attention problems, attention-deficit/hyperactivity disorder […]

Amsterdam Leads Bee Recovery Efforts by Banning Bee-Toxic Pesticides, Improving Habitat

(Beyond Pesticides, September 12, 2018) The city of Amsterdam, Netherlands is leading global bee recovery efforts by increasing its diversity of wild pollinator species, according to reporting and an analysis by NBC News. A new map published by the city identified 21 bee species not found in an earlier 1998 survey recorded by Amsterdam officials. The increase has been attributed to a range of pollinator-protective measures, including a ban on bee-toxic pesticides and the planting of native flowers, prioritized by the city government since the turn of the century. Local communities throughout the world can look to Amsterdam for policies and practices that will safeguard their own unique pollinator populations. The NBC News report notes several initiatives undertaken by the Amsterdam government. Many of these measures come out of a $38.5 million fund aimed at broadly improving environmental sustainability. “Insects are very important because they’re the start of the food chain,” said Geert Timmermans, an Amsterdam ecologist to NBC News. “When it goes well with the insects, it also goes well with the birds and mammals.” Insect and bee hotels are often installed in conjunction with the development of green roofs, which are encouraged for all new buildings. And parks […]

Study Finds Bumblebees Increasingly Attracted to the Pesticides that Kill Them

(Beyond Pesticides, August 31, 2018) Given the choice to forage on untreated or pesticide-contaminated food sources, bees will increasingly choose the pesticide, according to research published in Proceedings of the Royal Society B in late August. The data indicate that risks to pollinators grow, rather than wane, over time, making improved regulation over bee-toxic neonicotinoid pesticides even more climacteric. In essence, the study indicates that bees may be undertaking the human equivalent of chain-smoking themselves to death. Authors of the study note that numerous studies have been performed that subject bees to neonicotinoid-treated food, however this research generally allows pollinators to only forage on contaminated sources. While this provides important information on hazard criteria, it does not indicate risk of exposure. Positing the idea that pollinators may eventually seek to avoid neonicotinoid-contaminated nectar, researchers provided bumblebee colonies with a choice over the course of 10 days. At the start, the bees exhibited no discernable preference between toxic and nontoxic food. However, as time went on more and more bees fed from nectar laced with thiamethoxam, a widely used neonicotinoid. By the end of the experiment, food containing 2 parts per billion of the pesticide was eaten 10% more than in […]

Pesticides Contribute to Bird Declines, Threatening Forests, Crops, and Ecological Balance

(Beyond Pesticides, August 27, 2018) Beyond the visual and audial charms of some bird species, insect-eating birds play a significant role in controlling pests that can ruin crops or ravage forests. A meta-study by Martin Nyffeler, Ph.D. of the University of Basel in Switzerland finds that globally, birds annually consume 400-plus million metric tons of various insects, including moths, aphids, beetles, grasshoppers, crickets, and other arthropods (invertebrate organisms with exoskeletons, paired and jointed appendages, and segmented bodies, such as insects, crustaceans, and spiders). This research reviews 103 studies that examine the volume of insects consumed by various birds in seven of the world’s major biomes. In consuming such volumes of insects that can inflict damage on crops, trees, and other plants on which organisms may feed or otherwise depend, birds provide significant services to ecosystems, to denizens of habitats, and to human food system and economic interests; they also keep local ecosystems in balance. Threats to birds — and thus, to those ecosystem services — include those from pesticide use. Of the 10,700 known bird species distributed across the planet, more than 6,000 are primarily insectivorous. The study indicates that forest-dwelling birds consume the majority of insects (approximately 300 million metric […]

Canada Proposes to Phase-out Pesticides Linked to Bee Decline, Aquatic Risks

(Beyond Pesticides, August, 20, 2018) Health Canada’s Pest Management Regulatory Agency (PMRA) has announced a plan to phase out the outdoor use of two neonicotinoid insecticides — thiamethoxam and clothianidin — over three to five years, due to concerns about their effects on aquatic invertebrates. This comes after their 2016 proposal to phase out another neonicotinoid, imidacloprid, for the same concerns, but the proposal has not been finalized. In April, the European Union (EU) voted to ban the most widely used neonicotinoids, citing risks to bees. Earlier this year, PMRA proposed to phase out a number of uses of neonicotinoids in order to mitigate risks to pollinators. And now, after the Canadian agency initiated a special review based on a preliminary analysis of available information on the concentrations and frequency of detection of clothianidin in aquatic environment, the agency has proposed another round of phase-outs. The agency’s review focused on assessing potential risk to aquatic invertebrates exposed to clothianidin applied as a seed, foliar or soil treatment. The assessment finds that, in aquatic environments in Canada, clothianidin and thiamethoxam are both being measured at concentrations that are harmful to aquatic insects. These insects, according to the agency, are an important part of […]

Massachusetts Pollinator Advocates Vow to Advance Protections after Legislature Fails to Restrict Neonicotinoids

(Beyond Pesticides, August 9, 2018) Last week, the Massachusetts legislature failed to pass legislation that would have restricted the use of neonicotinoid pesticides in the state in order to protect sensitive pollinators, but advocates vow to campaign for a victory in the next legislative session. H. 4041, would have restricted neonicotinoid uses to certified applicators only. Massachusetts beekeepers lost 65 percent of honey bee hives this year, a rate 25 percent higher than the national average. H. 4041, An Act to Protect Massachusetts Pollinators, introduced in 2017, failed to make it to the floor before the end of the legislative session, which ended July 31. The bill gained the support of more than 100 Massachusetts scientists and academics who sent a letter to the Joint Committee on Environment, Natural Resources and Agriculture in support. Over 180 scientists, businesses, beekeepers, farmers, and conservationists formally endorsed this bill to restrict neonicotinoid use to licensed applicators. The Massachusetts County Beekeepers Association worked to organize an extensive grassroots advocacy movement in support of the bill. H.4041 would have placed “common-sense” restrictions on unlicensed use of neonicotinoids. It would require neonicotinoids to be used by licensed or certified applicators, and would also limit the use […]

Trump Administration Reverses Ban of Bee-Toxic Pesticides on National Wildlife Refuges, as California Confirms Neonicotinoid Pesticides Harm Bees

(Beyond Pesticides, August 7, 2018) At the same time that a new analysis by California’s Department of Pesticide Regulation (DPR) finds current neonicotinoid uses in the state expose bees to residue levels known to cause harm, the Trump administration has reversed a 2014 U.S. Fish and Wildlife (FWS) decision to ban neonicotinoids on National Wildlife Refuges. In 2014, newly passed state legislation required DPR to study the impacts of neonicotinoids (imidacloprid, thiamethoxam, clothianidin, and dinotefuran) and adopt control measures to protect sensitive pollinator health within two years. In its report, released last month, DPR finds the highest risk to bees is posed by use of two neonicotinoids, thiamethoxam and clothianidin, on cereal grains like corn, wheat, rice, and barley. The seeds of these crops are typically coated with neonicotinoids before planting, where residues persist in the pollen and nectar. Although these findings are not surprising and have been documented in the scientific literature, California’s analysis indicates neonicotinoids can cause much broader harm, including to pollinators commonly found on many types of vegetables, cereal grains, tree nuts, fruits and tobacco. Shortly after a decision in the Pacific Region, FWS announced that all National Wildlife Refuges would join in the phase-out of neonics (while also phasing out genetically […]
