(Beyond Pesticides, January 24, 2018) Poor nutrition coupled with exposure to a notorious class of insecticides known as neonicotinoids act synergistically to significantly reduce the survival of honey bees and their colonies, according to research published by scientists from University of California, San Diego (UCSD). This is the first study to delve into the real-world effects pesticide exposure can have on honey bees also subject to nutritional stress, a common occurrence in the wild. The outcome of this research highlights the weaknesses of the U.S. Environmental Protection Agency’s (EPA) testing regime for registering pesticides, which does not account for the complex ecology surrounding catastrophic declines in honey bee and other wild pollinator populations. UCSD scientists looked at two of the most popular neonicotinoids, chlothianidin and thiamethoxam, to investigate how realistic levels of exposure to the chemicals interacted with varying levels of available food. High and low levels of both chemicals, 1/5 and 1/25 of the LD50 (amount at which 50% of honey bees exposed would die) were added to sugar syrup solution containing a range of different nutrition levels. Sugar syrup, which mimics nectar and honey, is a critical source of carbohydrates for honey bees. The bees studied were either […]

(Beyond Pesticides, January 18, 2018) Research published in early January 2018 has shown that — despite a partial ban on neonicotinoid insecticides instituted in 2014 — 25% of British honey is still contaminated with residue of these “potent, bee-killing” pesticides. The partial ban, which extended to flowering crops, such as oilseed rape (from which canola oil is made), was instituted by the European Union (EU) in response to evidence of serious threats to bee populations. Samples for this study came from beekeepers and were each from a single location. After the partial ban went into effect, scientists had seen some reduction in the contamination rate of neonicotinoids in honey, from greater than 50% prior to the ban. This study demonstrates that these powerful pesticides nevertheless remain common in agricultural areas, posing serious threats to bees (and other pollinators). This discovery is likely to accelerate pressure on the EU to ban all outdoor use of neonicotinoids, with a vote coming perhaps as soon as in the next few months. “While the frequency of neonicotinoid contaminated samples fell once the EU ban was in place, our data suggest that these pesticides remain prevalent in the farming environment,” said Ben Woodcock, of the UK’s […]

(Beyond Pesticides, January 17, 2018) The organophosphate insecticides chlorpyrifos, malathion, and diazinon are likely to jeopardize the continued existence of endangered species and adversely modify their critical habitats, according to the newly released report from the National Marine Fisheries Service (NMFS). The insecticide cholorpyrifos, whose ban was rescinded by the Trump Administration last year, despite overwhelming evidence of neurological and brain damage to children, is once again being shown to be too toxic for continued use. Under Section 7 of the Endangered Species Act (ESA), any agency action requires a finding that it “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” The December 31, 2017 Biological Opinion from NMFS followed an ecological assessment that relied upon multiple lines of evidence to determine effects to species and their designated habitats. These include “the direct and indirect toxicity of each chemical to aquatic taxa groups (e.g. fish, mammals, invertebrates); specific chemical characteristics of each pesticide (e.g. degradation rates, bioaccumulation rates, sorption affinities, etc.); expected environmental concentrations calculated for generic aquatic habitats; authorized pesticide product labels; maps showing the spatial overlap of listed species’ habitats with pesticide use areas; […]

(Beyond Pesticides, January 16, 2018) In spite of findings that neonicotinoid (neonic) insecticides pose both acute and chronic risks to pollinators, aquatic life, and birds, the U.S. Environmental Protection Agency (EPA) is seeking comment that could support their continued use. Comments are due by February 20, 2018.  Tell EPA that neonics pose unacceptable risks to pollinators, aquatic life, and birds! And, ask your Congressional delegation push EPA to do the right thing. Last month, EPA released preliminary ecological (non-pollinator) assessments for the neonicotinoids clothianidin, thiamethoxam, dinotefuran, and the terrestrial ecological assessment for imidacloprid, finding that these pesticides pose both acute and chronic risks to aquatic life and birds. Treated seeds are identified as posing the highest dietary risks to birds, confirming previous research that neonics are highly hazardous not only to bees, but also, to birds, aquatic life, and other non-target organisms. However, EPA’s assessments also cover spray treatments. EPA opened the public comment period for these assessments on December 15, 2017. Along with outlining the risks identified in the assessments, the agency is especially requesting feedback on the benefits of continued use of the neonics on cotton and citrus crops, identified in last year’s pollinator assessments as posing risks to honey bees. […]

(Beyond Pesticides, January 11, 2018) A California court has halted a state program allowing pesticide spraying at schools, organic farms, and backyards across California because of inadequate public disclosure of the chemicals’ adverse effects. The California Department of Food and Agriculture’s (CDFA) statewide “pest management” program required no site-specific analysis of risks before the application of 79 pesticides, including some known to cause cancer and birth defects and to be highly toxic to bees, butterflies, fish and birds. Relating to the broad application of pesticide use allowances under the state’s required Program Environmental Impact Report (PEIR), issues of concern in the case included: i) a failure to conduct site-specific environmental impact asssessment, while allowing the “substantially similar” uses without environmental review; (ii) broad application of a PEIR to subsequent activities without a Notice of Determination ; (iii) includes an inadequate project description; (iv) a failure to adequately describe the baseline environmental conditions; (v) a failure to adequately analyze the Project’s environmental impacts (including biological, water, human health, and farming impacts); (vi) a failure to adequately analyze cumulative impacts; (vii) legally inadequate mitigation measures; (vii) a failure to consider a reasonable range of alternatives; and (viii) a failure comply with public agency consultation […]

(Beyond Pesticides, January 4, 2018) Last month, the U.S. Environmental Protection Agency (EPA) released the preliminary ecological (non-pollinator) assessments for the neonicotinoids (neonics); clothianidin, thiamethoxam, dinotefuran, and the terrestrial ecological assessment for imidacloprid, finding that these pesticides pose both acute and chronic risks to aquatic life and birds. Treated seeds are identified as posing the highest dietary risks to birds, confirming previous research that neonics are highly hazardous not only to bees, but to birds, aquatic life, and other non-target organisms. Released December 15, 2017, EPA opened the public comment period for these assessments until February 20, 2018. Along with the risks identified in the assessments, the agency is specially requesting feedback on the benefits of continued use of the neonics in cotton and citrus crops identified in last year’s pollinator assessments as posing risks to honey bees. EPA states, “We believe early input from the public will be helpful in developing possible mitigation options that may be needed to address risks to bees.” This despite evidence of long-term systemic exposures to non-target organisms that support a phase-out of these pesticides. EPA believes that neonicotinoids are crucial for the management of Asian citrus psyllid, an invasive pest that causes citrus greening, […]

(Beyond Pesticides, December 15, 2017) The Trump Administration’s pick to become the Environmental Protection Agency (EPA) Assistant Administrator for Chemical Safety and Pollution Prevention, Michael Dourson, PhD, has withdrawn his name from consideration after it became increasingly likely he would not pass Senate confirmation due to his deep connections to the chemical industry. In a letter obtained by the Associated Press, Dr. Dourson indicated his move “avoids unnecessarily politicizing the important environmental protection goals of Administrator Pruitt.” Health and environmental groups, including Beyond Pesticides, which launched a campaign against Dr. Dourson’s nomination, are pleased by the withdrawal announcement, but remained deeply concerned with the Trump administration’s continued propensity to promote industry interests and industry-backed nominees over real measures to safeguard environmental health and justice. Dr. Dourson’s withdrawal was predicated on reports in November that North Carolina’s two Republican Senators, Richard Burr and Thom Tillis, planned to vote against Dourson’s appointment.  North Carolina is the midst of a growing scandal implicating Chemours, a company spun-off from chemical giant DuPont in 2015, in widespread water contamination with the chemical GenX, used to make Teflon and other industrial products. Chemours operates a GenX production plant in Fayetteville, NC, and is accused of regularly […]

(Beyond Pesticides, December 14, 2017) Tests of waterways in the United Kingdom (UK) reveal rivers contaminated with neonicotinoids, the class of chemicals highly toxic to bees and aquatic invertebrates. And now, although neonicotinoids were banned from use on certain crops in the European Union (EU) in 2013, an EU vote to extend the ban has been delayed. The test results raise concerns over neonicotinoids’ impacts on waterways, especially to fish and birds. Under a new EU mandate -Water Framework Directive ‘Watch List’ initiative – the UK was required to monitor for all five commonly used neonicotinoids: imidacloprid, clothianidin, thiamethoxam, acetamiprid and thiacloprid. Twenty-three sites were sampled in 2016, 16 in England, four in Scotland, three in Wales and three in Northern Ireland. This is the first systematic testing of neonicotinoids in rivers in Britain. According to the results, half the rivers tested in England had either chronic or acute levels of contamination. Of the 23 rivers tested across Britain, all but six contain neonicotinoids. Eight rivers in England exceed recommended chronic pollution limits, and two are acutely polluted. Neonicotinoids are not only highly toxic to bees but also highly toxic to aquatic insects, which are a vital food source to […]

(Beyond Pesticides, December 6, 2017) Last week over 100 conservation and environmental groups urged the federal government to increase funding to protect and conserve monarch butterflies. These iconic butterflies, native to North America, have seen drastic declines in their populations. Surveys report over 80 percent reductions in populations over the last 20 years. Pesticide use, habitat loss, and climate change have all been identified as stressors to these butterflies. The groups, led by the Center for Biological Diversity, Defenders of Wildlife, and the Humane Society, sent a letter to the U.S. Department of Agriculture (USDA) to do more to help the imperiled butterfly. The letter requests the agency increase the allotment of conservation funds from $4 million- spent last year- to $100 million. The increase in funds is needed for efforts to increase milkweed habitat. In contrast, the government spent over $500 million on sage grouse initiatives to prevent that animal’s listing under the Endangered Species Act (ESA), even though the Trump Administration is seeking to overturn these initiatives. Currently, the agency has taken some steps to protect monarchs. These include the implementation of the Monarch Butterfly Habitat Development Project and support of the Monarch Butterfly Conservation Fund. But, according […]

(Beyond Pesticides, December 1, 2017) Ichneumonid wasps (family Ichneumonidae), are a widely distributed parasitoid wasp family within the order Hymenoptera. The name “ichneumonid” comes from Greek words meaning “tracker” and “footprint.” And females do indeed hunt for suitable “hosts” by first identifying the organism’s food source. Once a suitable host is found, females deposit eggs onto the unsuspecting insect larvae where, within ten days to several weeks, the Ichneumonid larva kills the host by feeding on its body fluids before it emerges. They are also known as “scorpion wasps” for the extreme length and curving motion of their segmented abdomens. Note: both adult males and females are stingless, and feed on nectar. The discovery of Ichneumonidae was so troubling to many that, in 1860, Charles Darwin wrote a letter to the American naturalist Asa Gray, saying: “I own that I [should wish to] see as plainly as others do…evidence of design and beneficence on all sides of us…I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice.” The parasitic behavior of Ichneumon wasps was […]

(Beyond Pesticides, November 30, 2017)  A French court suspended the license of two pesticide products citing their toxicity to bees. The products, Closer and Transform, both contain the active ingredient, sulfoxaflor, which is highly toxic to bees. The ruling overturned the decision by France’s health and environment agency, ANSES, to allow the use of the sulfoxaflor products. Sulfoxaflor use was also challenged in the U.S. by beekeepers concerned about its impact on already declining bee populations. Sulfoxaflor is a relatively new active ingredient whose mode of action is similar to that of neonicotinoid pesticides. Even though it has not been classified as a neonicotinoid, it elicits similar neurological responses in honey bees, with many believing that sulfoxaflor is a new generation of neonicotinoid. Its initial 2013  U.S. registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and the U.S. Environmental Protection Agency’s (EPA) inadequate review of the data. The court concluded that EPA violated federal law when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide may have on honey bee colonies. By vacating EPA’s unconditional registration of the chemical, sulfoxaflor could not be used […]

(Beyond Pesticides, November 22-23, 2017) As we sit with friends and family this Thanksgiving, let us appreciate how our delicious meal got to your table. The turkey, potatoes, stuffing, and cider all originated in fields far from our homes, and those working in those fields deserve our thanks. They deserve our thanks because many of these workers work long hours, under deplorable conditions, and are exposed to pesticides that put their health and that of their families at risk. So, as we enjoy our pumpkin pie, cranberry sauce, and apple crumble, remember all the hardworking farmworkers who have helped to bring our meal to the Thanksgiving table. At the same time, we give thanks for the environment that is so plentiful and nurturing of life, and remember the importance of pollinators and biodiversity in sustaining life. Celebrating Thanksgiving and looking toward another year coming to an end, provides an opportunity for us to remember to remain vigilant, and raise our voices against efforts to erode our environmental protections that safeguard human health and preserve biodiverse ecosystems. Thanking Farmworkers Farm work is hard and dangerous work. Each year millions of farmworkers, including seasonal and migrant workers, toil in fields across the […]

(Beyond Pesticides, November 15, 2017) Songbirds exposed to widely used insecticides fail to properly orient themselves for migration, according to a study published by Canadian scientists in Scientific Reports. With the organophosphate chlorpyrifos and the neonicotinoid imidacloprid applied to millions of acres of farmland throughout North America, this new research adds weight to arguments that pesticides are a likely cause in the decline of migratory bird populations. “Studies on the risks of neonicotinoids have often focused on bees that have been experiencing population declines. However, it is not just bees that are being affected by these insecticides,” said Christy Morrissey, PhD, biology professor at the University of Saskatchewan. Researchers captured 57 white crowned sparrows in northern Canada, and held them in an outdoor pen for roughly two weeks, during which time all the birds either gained or maintained their weight. The songbirds were then split into three groups, one exposed to imidacloprid, another to chlorpyrifos, and the last untreated and acting as a control. The imidacloprid and chlorpyrifos exposed groups were each further separated by exposing a portion to the insecticide at 10% of the lethal dose that would kill 50% of a given population (LD50), and another to 25% […]

(Beyond Pesticides, October 12, 2017) Honey throughout the world is contaminated with neonicotinoid insecticides, chemicals implicated in global decline of pollinator populations. The extent of contamination recorded in the new Science study —with the chemicals detected on every continent except Antarctica, even in honey produced in small isolated islands— is symptomatic of a world awash in toxic pesticides. The results call into question globalized mores that have permitted chemical insecticides to pervade the environment, and signal the need to transform pest management to integrated organic systems that respect nature. Neonicotinoids are systemic pesticides that are taken up by a plant’s vascular system and transported into the pollen, nectar, and guttation (drops of xylem sap) drops the plant produces. They are mobile in soil, so quantities of the chemical that are not taken up by plants after an application leach through the soil column into local waterways. Pollinators come into contact with these insecticides through their normal course of foraging and pollination. Out of 198 honey samples collected as part of a global citizen science project and subsequently tested by Swiss scientists, 75% of samples contained a measurable level of neonicotinoids. Broken down by region, North America represented the highest frequency […]

(Beyond Pesticides, October 11, 2017) Last week, the Natural Resources Defense Council (NRDC) filed a lawsuit challenging the U.S. Environmental Protection Agency’s (EPA) registration of neonicotinoid pesticides – acetamiprid, dinotefuran, and imidacloprid, and the agency’s failure to first consult with the U.S. Fish and Wildlife Service on the pesticides’ impact on threatened or endangered species. The lawsuit, filed in the U.S. District Court for the District of Columbia, challenges the failure of the federal government to evaluate the impacts of neonicotinoid pesticides (“neonics”) on threatened and endangered species, like the rusty patched bumble bee, the black-capped vireo, and the San Bruno elfin butterfly. The suit cites widespread presence of neonics in the environment which presents serious risks to wildlife across large portions of the country. It contends that they pose significant adverse consequences to threatened and endangered species. According to the lawsuit, because of toxicity and pervasive environmental contamination, NRDC is now challenging EPA’s registrations of pesticide products containing one of three main neonic active ingredients—acetamiprid, dinotefuran, and imidacloprid—and seeks vacatur of those registrations until EPA complies with the law. “The EPA ignored endangered bees, butterflies, and birds when it approved the widespread use of neonics,” said Rebecca Riley, a senior […]

(Beyond Pesticides, September 21, 2017) The First District California Court of Appeal issued an opinion Tuesday in a lawsuit challenging a California Department of Pesticide Regulation (DPR) decision to approve additional uses for two bee-killing pesticides without disclosing the impact on honeybees. Pesticide Action Network, Center for Food Safety, and Beyond Pesticides, represented by Earthjustice, filed the underlying lawsuit in 2014, seeking to halt DPR’s practice of approving ever more uses for neonicotinoid pesticides pending completion of the agency’s languishing scientific review of the evidence linking agricultural use of neonicotinoids to a global honeybee die-off. DPR began its scientific review in early 2009 after it received evidence that neonicotinoids are killing bees, but DPR has yet to complete its review or take meaningful action to protect bees. Instead, DPR has continued to allow increased use of neonicotinoids in California. “DPR acknowledged almost 10 years ago that neonicotinoids are killing bees, yet the agency has approved more and more uses for these toxic pesticides every year since,” said Earthjustice attorney Greg Loarie, who represented the groups. “It’s time for DPR to do its job and protect honeybees and the multi-billion dollar agricultural economy that bees make possible in this State.” At issue […]

(Beyond Pesticides, September 1, 2017) Tell your Governor to stop Monsanto from making false and deceptive claims about glyphosate (Roundup) –a pesticide that hurts workers. Because of its wide use by workers in parks, along utility and railroad rights-of-way, and on farms, use of Monsanto’s glyphosate results in more exposure than any other pesticide. Monsanto has developed and continues to grow its market for this product with false claims of the safety of the toxic chemical. Glyphosate is listed as a probable carcinogen by the International Agency for Research on Cancer (World Health Organization) and disrupts a pathway in humans necessary for healthy functioning of the gut microbiome. Meanwhile, Monsanto actively advertises and promotes its Roundup products as targeting an enzyme “found in plants but not in people or pets.” Act now to urge your Governor to act on false claims by Monsanto. Although EPA considers glyphosate to be “of relatively low oral and dermal acute toxicity,” symptoms workers could experience following exposure to glyphosate formulations include: swollen eyes, face, and joints; facial numbness; burning and/or itching skin; blisters; rapid heart rate; elevated blood pressure; chest pains, congestion; coughing; headache; and nausea. The additional ingredients in Roundup can be more toxic […]

(Beyond Pesticides, August 28, 2017) School policies must protect children from pesticides by adopting organic land and building management policies and serving organic food in cafeterias. At the start of the school year, it is critical for school administrators to make sure that students and teachers are learning and teaching in an environment where no hazardous pesticides are used in the school’s buildings or on playing fields. It is also essential that children have access to organic food in food programs and manage school gardens organically. Send a letter to your local officials urging them to tell school districts to adopt organic management and serve organic food to students. In addition, there are other things you can do: Whether a parent, teacher, student, school administrator, landscaper or community advocate, there are steps that should be taken to make sure the school environment is a safe from toxic chemicals, as the new school year begins. For Parents and Teachers: Because children face unique hazards from pesticide exposure due to their smaller size and developing organ systems, using toxic pesticides to get control insects, germs, and weeds can harm students much more than it helps. The good news is that these poisons are unnecessary, given the availability of […]

(Beyond Pesticides, August 24, 2017) Common pesticides used on canola crops significantly reduce bumblebee egg laying and may lead to local population extinction, according to new research published in the journal Nature by scientists at the Royal Holloway University of London. This is the latest study to investigate how neonicotinoids, insecticides linked to the global decline of pollinator populations, are changing the landscape that humans rely on for food production and other ecological services. Although this eye-opening study should be a wake-up call for regulators in the U.S., there is little indication that federal agencies tasked with protecting pollinators and the wider environment are willing to make changes that would affect the profits of multinational chemical companies. Researchers began their study by visiting canola fields in the United Kingdom that had been treated with neonicotinoids, observing the distribution of various bumblebee species. One of the most abundant species found is Bombus terrestris, a key pollinator and the most common bumblebee throughout Europe. Colonies of B. terrestris were then purchased commercially, and roughly 230 queens were successfully mated in the lab. In addition to pesticide exposure, scientists used length of hibernation as a variable in their experiment. This is because bumblebee […]

(Beyond Pesticides, August 23, 2017) The Center for Food Safety (CFS) filed a federal lawsuit to stop the U.S. Army Corps of Engineers from moving forward with an expansion of industrial shellfish aquaculture on the Washington state coast without any water quality or marine life protections from pesticide use and habitat loss. This is just the latest in efforts to protect sensitive coastal areas in Washington from shellfish farming that is contributing to increased pesticide use and environmental degradation. The lawsuit, filed in the U.S. District Court for the Western District of Washington earlier this month, challenges the U.S. Army Corps of Engineers (Corps) issuance of a nationwide permit (NWP 48), which, according to the suit, “greenlights a massive expansion of shellfish aquaculture with entirely inadequate protections.” The Corps has a duty to protect public water from adverse impacts, but potential environmental impacts have not properly assessed or considered, the suit claims, in violation of the Corps’ environmental protection mission. The lawsuit argues that the Corps, when it approved the Washington state permit, violated numerous environmental laws, including the Clean Water Act, National Environmental Policy Act, and Administrative Procedure Act. According to CFS, the permit issued will allow shellfish aquaculture acreage […]

(Beyond Pesticides, August 10, 2017)  New data released by the U.S. Department of Agriculture (USDA) earlier this month, indicating a slight increase in the number of honey bee colonies, is masked by beekeepers’ efforts to split hives in the face of losses. The USDA reports that Colony Collapse Disorder losses (CCD) are down 27% compared to the past year. While these numbers may seem to be a positive sign after over a decade of consistent pollinator declines, they are more indicative of a beekeeping industry that is using every available tactic possible to stay viable. With the continued use of highly toxic neonicotinoid insecticides in farms, gardens, and public spaces throughout the country, the long-term health honey bees and other pollinators continue to be in jeopardy. According to USDA’s National Agricultural Statistics Service (NASS), the number of beekeeping operations with five or more colonies reported a total of 2.89 million colonies in April 2017, a 3% increase from April 2016, when numbers stood at 2.80 million. News media such as Bloomberg hailed this report in an article headlined “Bees Are Bouncing Back From Colony Collapse Disorder.” However, a closer look into the numbers and beekeeper accounts reveals what is actually occurring. A more accurate […]

(Beyond Pesticides, August 2, 2017). August’s PolliNATION Pollinator of the Month is the Pollen Wasp! Pollen wasps, of the small subfamily Masarinae are the only “vegetarian” wasp in the family Vespidae., They feed solely on nectar and pollen, unlike their more aggressive Vespid wasp cousins. There are 300 species of pollen wasp from 14 genera spread across the globe, however, in the U.S., all 14 species of pollen wasps originate from the genus Pseudomasaris. Range Pollen wasps are found throughout the world, though they tend to concentrate in arid areas of southern Africa, and North and South America. They are not documented in the tropics or in Antarctica. In the United States, they can be found from Washington to as far south as New Mexico, and as far east as Nebraska. They are solitary pollinators who make their nests out of mud, often attached to branches, rocks, or hanging off ledges. Diet and Pollination Pollen wasps differ from their omnivorous Vespid wasp relatives by rearing their young on nectar and pollen, rather than other insects. They are the only Vespid species which do so. Their nests, made up of a mixture of soil and nectar, are usually comprised of 4-10 […]
