(Beyond Pesticides, August 23, 2022) Bees exposed to systemic insecticides become disoriented and cannot walk straight, showing evidence of brain damage in areas that coordinate movement, according to research published in Frontiers in Insect Science. Although scientific studies and regulatory determinations have already provided ample evidence implicating systemic insecticides like the neonicotinoids and sulfoxaflor with pollinator danger and decline, new research continues to fill in the remaining gaps. “Here we show that commonly used insecticides like sulfoxaflor and the neonicotinoid imidacloprid can profoundly impair the visually guided behavior of honey bees,” said lead author Rachel H Parkinson, PhD, a scientist at the University of Oxford. “Our results are reason for concern because the ability of bees to respond appropriately to visual information is crucial for their flight and navigation, and thus their survival.” Honey bees rely on landmarks, the direction of sunlight, and wide-field visual motion to orient themselves in a landscape, find nectar and pollen, and bring it back to the hive. While sunlight provides a compass, wide-field visual motion helps bees adjust speed and altitude, and determine where they are relative to known landmarks. Worker bees use this innate ability to reorient themselves to food or their hive […]

(Beyond Pesticides, June 14, 2022) The ringleader of a pesticide smuggling operation conducted across the United States border with Mexico has been sentenced to eight months in prison by a U.S. District Court Judge. According to a press release by the U.S. Attorney’s Office for the Southern District of California, Sofia Mancera Morales used individuals recruited over social media Bovitraz and Taktic, pesticide products banned in the US that pose hazards to pollinators and cancer risks to humans. “In exchange for ill-begotten profits, this cavalier smuggling operation was more than willing to risk the public’s health and the honeybee industry, which is critical to pollinating our food supply,” said U.S. Attorney Randy Grossman. While the Department of Justice deserves praise for this enforcement action, health and environmental advocates say that more must be done to stop illegal pesticide sales. A quick search for the two pesticide products in question brings up webpages, including well-known sites like Etsy.com, where the same illegal pesticides cited in this case are currently being sold to U.S. consumers. Over Facebook, Ms. Morales offered to pay individuals between $40-150 per package of pesticide products they delivered across the border. Those recruited were instructed to open a […]

(Beyond Pesticides, June 7, 2022) Bumblebee colonies exposed to low levels of the weed killer glyphosate are unable to adequately regulate nest temperature, imperiling the next generation of bumblebees and long-term colony growth and survival. This latest finding, published this month in the journal Science, is a stark reminder that a pesticide does not have to kill an animal outright in order to create effects that ultimately result in death and population declines. “Sublethal effects, i.e. effects on organisms that are not lethal but can be seen, for example, in the animals’ physiology or behaviour, can have a significant negative impact and should be taken into account when pesticides are approved in future,” said Anja Weidenmüller, PhD, of the University of Konstanz, Germany. With regulators at the U.S. Environmental Protection Agency (EPA) refusing to adequately account for sublethal impacts, and myopically focused on the acute effects of pesticide exposure, bumblebee populations in the United States are in free fall and require urgent protective action. To better understand how glyphosate exposure affects bumblebee colony growth and brood (young larval bee) development, researchers first split colonies in two. One side of the colony was fed sugar water containing 5mg/liter of glyphosate, while […]

(Beyond Pesticides, March 25, 2022) Recent coverage by The Guardian of the U.S. Environmental Protection Agency’s (EPA’s) plan — to extend the registration of several demonstrably harmful neonicotinoid insecticides — compels Beyond Pesticides to identify, once again, the agency’s failures to enact its core mission. That mission is “to protect human health and the environment,” and to ensure that “national efforts to reduce environmental risks are based on the best available scientific information.” EPA has undertaken a review of the registration of several members of the neonicotinoid (neonic) family of pesticides and, despite the agency’s own findings of evidence of serious threats to pollinators, aquatic invertebrates, and other wildlife, it issued interim decisions on these neonics in January 2020 that disregard the science on the pesticides’ impacts. EPA appears to be prepared to finalize these registrations late in 2022; this would, barring further action, extend the use of these harmful compounds for 15 years. Neonics are used widely in the U.S., both on crops to kill sucking insects, and as seed treatments with the same goal for the developing plant. These insecticides are systemic compounds, meaning that once applied, they travel to all parts of a plant through the vascular […]

(Beyond Pesticides, January 28, 2022) Do city dwellers, who typically have smaller-sized greenspaces on their lots, have any role to play in supporting pollinators? Absolutely, according to a recent study of Bristol, England residential gardens. The researchers find that the amount of “floral resource” — the abundance of actual blooms, which translates roughly to amount of nectar production — varies widely across gardens and yards, and that small urban gardens and greenspaces are actually some of the most pollinator-friendly resources. The study notes that that several factors influence how well these resources provide food for pollinators, most important among which are pollinator-friendly management practices. Beyond Pesticides notes that there are multiple resources in the U.S. on making gardens and greenspaces “friendly” and useful to pollinators, including its own BEE Protective guidance on garden and landscape management, and that employing organic management practices is critical. The researchers hope to “develop evidence-based management recommendations to support pollinator conservation in towns and cities.” Their paper, published in the Journal of Applied Ecology, reports that the size of the Bristol gardens they studied actually had minimal relationship to the amount of nectar produced by the plants in them. There are factors beyond size that determine the […]

(Beyond Pesticides, December 10, 2021) In a win for pollinators, a California Superior Court has issued a ruling that sulfoxaflor, a systemic pesticide that is “field legal” but “bee lethal,” can no longer be used in the state. The suit was brought by the Pollinator Stewardship Council and the American Beekeeping Federation. The ruling of the Superior Court of the State of California for Alameda County finds that the argument of the petitioners — that sulfoxaflor approval decisions by the California Department of Pesticide Regulation (DPR) violated the California Environmental Quality Act (CEQA) — is valid. Eliminating this highly bee-toxic pesticide from use in the state is expected to protect not only native bees and other pollinators (including Monarch butterflies in early Spring), but also, the many millions of managed-colony bees that are transported to California for pollination of almond and other crops. The suit was filed against DPR, Corteva inc., Dow Agrosciences LLC, the Siskiyou County Department of Agriculture, and James E. Smith as Siskiyou County Agricultural Commissioner. Having found for the petitioners’ request for a Writ of Mandate (a court order requiring a lower court or public authority to perform its statutory duty), the court instructed the petitioners to […]

  (Beyond Pesticides, November 24, 2021) On Thanksgiving, thank you for being a part of Beyond Pesticides and sharing and contributing to the vision necessary to protect the web and fragility of life. We believe that there is no time like Thanksgiving to think about how we can more effectively join together as families and communities across divisions and different points of view to find a common purpose in protecting the health of the environment and all that inhabit it. Unfortunately, there are a host of pesticides, genetically engineered materials, and others in conventional Thanksgiving foods that not only impact human health, but threaten the environment. With far too many adverse health and ecological effects associated with toxic chemicals, organic practices are viable solutions to mitigate pesticide contamination and subsequent exposure. Read on as we consider the range of challenges we must confront, and the solutions that can bring us all together. The Climate As climate impacts grow, an increase in uses of synthetic pesticides in agriculture is likely — because of waning efficacy (pesticide resistance) of these compounds, and mounting pest pressure (i.e., increasing insect population and metabolism). Production of pesticides contributes to greenhouse gas emissions gas (e.g., nitrous […]

(Beyond Pesticides, November 19, 2021) Thanksgiving offers an opportunity for people to come together and give thanks for the bounty of an organic harvest. Unfortunately, many Thanksgiving meals are produced by chemical farming practices that utilize hazardous pesticides, genetically engineered (GE) crops, and petroleum-based synthetic fertilizers. These inputs, apart from being unnecessary, degrade ecosystems and affect the health of consumers and agricultural workers alike. It’s never too late to start a new tradition – for this year and into the future, make your Thanksgiving feast sustainable by going organic. Now, more than ever, it’s important to go organic: For Our Own Health Going organic drastically reduces the amount of pesticide in a person’s body. Although Thanksgiving is generally no time to think about dieting, we’ll aim to make it instructive: recent research finds that one of the biggest health benefits of the Mediterranean Diet comes when you go organic. Compared to individuals on a Mediterranean diet filled with chemically farmed foods, those that ate organic had 91% lower pesticide residue. This finding is backed up by a considerable body of prior research. A 2015 study based on self-reported food intake found that those who eat organic generally have much lower […]

(Beyond Pesticides, October 18, 2021) The most recent science on pesticides raises serious health and environmental effects associated with pesticide use for lawn and landscape management. While the data is often not assembled in one place, updated factsheets bring together the science on the 40 commonly used pesticides used for conventional landscape management. Governors have the authority to stop the use of these hazardous materials that are used on parks and playgrounds, either by executive order or through their work with their state legislature, and transition land management to organic practices. Tell your governor to stop hazardous pesticide use on state lands and transition to organic land management. The new factsheets document with scientific citations a wide range of diseases and ecological effects linked to pesticides. The underlying analysis supporting the adverse health and environmental effects identified in the factsheets are based on toxicity determinations in government reviews and university studies and databases. What do the factsheets disclose? Of the 40 most commonly used lawn and landscape pesticides, in reference to adverse health effects… 26 are possible and/or known carcinogens 24 have the potential to disrupt the endocrine (hormonal) system 29 are linked to reproductive effects and sexual dysfunction 21 […]

Health and environmental effects disclosed on factsheets to guide community decisions on lawn and landscape management that do not poison people and contaminate the environment. WASHINGTON, D.C. (October 14, 2021) — Today, the national environmental and public health group Beyond Pesticides is releasing its health and environmental effects factsheets for “40 Commonly Used Lawn Pesticides,” updating and expanding on previous factsheets on 30 pesticides. These comprehensive factsheets documents with scientific citations a wide range of diseases and ecological effects linked to pesticides. The underlying analysis supporting the adverse health and environmental effects identified in the factsheets are based on toxicity determinations in government reviews and university studies and databases. What do the factsheets disclose? Of the 40 most commonly used lawn and landscape pesticides, in reference to adverse health effects, 26 are possible and/or known carcinogens, 24 have the potential to disrupt the endocrine (hormonal) system, 29 are linked to reproductive effects and sexual dysfunction, 21 have been linked to birth defects, 24 are neurotoxic, 32 can cause kidney or liver damage, and 33 are sensitizers and/or irritants. Regarding adverse environmental effects, 21 are detected in groundwater, 24 have the ability to leach into drinking water sources, 39 are toxic to […]

(Beyond Pesticides, August 23, 2021) “Biopesticides”—widely regarded as an alternative to chemical pesticides and hence given a special status in regulation—need a better definition. “Biopesticide” is generally poorly understood, and defined differently by various entities and stakeholders. The term can be misleading and mixes contradictory approaches. It is troublesome when we continue to look for product replacements or substitutions for agricultural practices that are clearly ineffective, and in the process avoid the changes necessary to transition to organic practices, which represent the real, long-term solution to concerns among chemical-intensive farmers that they are losing pesticides in their arsenal, either to organism resistance or regulatory restrictions. The U.S. Environmental Protection Agency (EPA) uses the following definition for “biopesticides”: Substances that interfere with mating, such as insect sex pheromones, as well as various scented plant extracts that attract insect pests to traps (and synthetic analogs of such biochemicals); Microbial pesticides consisting of a microorganism (e.g., a bacterium, fungus, virus or protozoan) as the active ingredient; Plant-Incorporated-Protectants (PIPs), pesticidal substances that plants are genetically engineered to produce. Tell EPA it’s time to redefine “biopesticide.” It is deceptive and misleading. The definition should not include genetically modified organisms or synthetic analogs of naturally occurring […]

(Beyond Pesticides, May 14, 2021) In a prime example of cart-before-the-horse, greenwashing, or perhaps “beewashing,” a British company has badly missed the mark in its latest attempt to market a product while “doing good” and generating goodwill with customers. As The Guardian reports, Marks & Spencer, the giant United Kingdom (UK) retailer, is releasing 30 million managed honey bees into rural British landscapes in what the company is promoting as an effort to support biodiversity and the beekeeping sector. However, according to experts and environmental advocates, unleashing that many honey bees may well actually harm both wild native bees and honey bees themselves. Critics of the move say this means that wild bees will likely face fiercer competition for already inadequate food sources. Beyond Pesticides adds that these honey bees have been dispatched to the same pesticide-contaminated habitats in which existing bee populations of all kinds face harmful exposures — exacerbating issues surrounding pollinator decline rather than solving them. Marks & Spencer’s Twitter marketing promotes the project in this way: “Did you know that bees contribute to a third of the food we eat? At M&S, we’re introducing more than 30 million bees to our Select Farms to help protect the […]

(Beyond Pesticides, May 7, 2021) Soil health is one of the linchpins on which the food production that sustains human life — as well as biodiversity, pollinator health, and carbon sequestration — depend. A recent meta-review of nearly 400 studies finds that, in 71% of the cases reviewed, pesticides kill or otherwise harm soil invertebrates that contribute mightily to soil health. In their paper, “Pesticides and Soil Invertebrates: A Hazard Assessment,” published in Frontiers in Environmental Science in early May, the researchers write, “A wide variety of soil-dwelling invertebrates display sensitivity to pesticides of all types . . . [These results] support the need for pesticide regulatory agencies to account for the risks that pesticides pose to soil invertebrates and soil ecosystems.” Beyond Pesticides, which has long reported on impacts of pesticides on soil health, concurs with that conclusion, and adds that the real solutions to noxious pesticide impacts lie in the adoption of  regenerative organic approaches to all land management because they obviate any need for petroleum-based toxic chemical controls. The term “pesticide” can refer to myriad kinds of chemical treatments — including antimicrobials, disinfectants, rodenticides, and others — but in the agricultural and land management realms, primarily means insecticides, […]

(Beyond Pesticides, April 13, 2021) A new study is making it increasingly clear that current laws are not protecting wild, ground nesting bees from the hazards of neonicotinoid insecticides. According to research conducted under a grant from the U.S. Department of Agriculture’s Sustainable Agriculture Research and Education (SARE) projects, Blue Orchard Mason Bees (Osima spp) are at particular risk from pesticide-contaminated soil they use to create their nest. Authors of the study note that with honey bees already in decline, pollination services provided wild managed bees like Mason bees are growing in importance. “Wild bees such as Osmia are becoming increasingly popular as managed pollinators in many systems, as there is growing concern that honeybees may not be able to continue to meet the increasing demands of agricultural pollination if these trends continue,” the study reads. The study looked at three overarching threats to mason bee populations, aiming to identify risks from pesticide contaminated soil used as a nest, effects on larvae exposed to contaminated soil, and whether female mason bees could determine the difference between contaminated and uncontaminated soil. “Imidacloprid is a neonicotinoid, which is a group of pesticides that are highly toxic to bees,” said Christine Fortuin, PhD, […]

(Beyond Pesticides, March 3, 2021) Earlier this week, pesticide regulators in the commonwealth of Massachusetts voted to restrict outdoor consumer uses of neonicotinoid insecticides. The move is the result of sustained advocacy from broad coalition of individuals and organizations focused on protecting pollinators and ecosystem health. While advocates are pleased that the Pesticide Board Subcommittee made Massachusetts the first state in the country to restrict neonicotinoids through a regulatory process, they note this is only the first step in eliminating these hazardous insecticides. “This marks an incremental victory which took us 6 years to land, and it only happened because of immense, ongoing grassroots action and legislative allies who are willing to hold state regulators accountable,” said Martin Dagoberto, Policy Director of the Northeast Organic Farming Association, Mass. Chapter in a press release. “We still have a monumental endeavor ahead if we are to reduce toxins and rein in the toxic influence of the chemical lobby,” Mr. Dagoberto added. Advocates had been pushing the legislature to pass An Act to protect Massachusetts Pollinators, sponsored by pollinator champion Representative Carolyn Dykema, since 2014. Following several failures by state lawmakers to bring the bill over the finish line, efforts in 2019 resulted […]

(Beyond Pesticides, August 6, 2020) New research finds that a decline in wild pollinator abundance, notably wild bees, limits crop yields in the U.S., according to the study, “Crop Production in the USA Is Frequently Limited by A Lack of Pollinators.” The study results, published in the journal Proceedings of the Royal Society B, find the annual, national average value of wild bee pollination for the most economically important and pollinator-dependent crops is approximately $1.5 billion, with the total value of all U.S. pollinator-dependent crops equaling $50 billion annually. The United Nations states that 75% of the 115 top global food crops depend on insect pollination, with one third of all U.S. crops dependent on pollinators, according to the U.S. Department of Agriculture (USDA). However, research finds that many insect populations are declining by half with a third threatened by extinction, including managed and wild pollinators, mainly due to habitat fragmentation, climate change, and extensive pesticide use. With the global reliance on pollinator-dependent crops increasing over the past decades, a lack of pollinators threatens food security and stability. The researchers in the study note, “Our findings show that pollinator declines could translate directly into decreased yields or production for most of the crops studied, […]

(Beyond Pesticides, July 28, 2020) With honey bees around the world under threat from toxic pesticide use, researchers are investigating a new way to track environmental contaminants in bee hives. This new product, APIStrip (Adsorb Pesticide In-hive Strip), can be placed into bee hives and act as a passive sampler for pesticide pollution. Honey bees are sentinel species for environmental pollutants, and this new technology could provide a helpful way not only for beekeepers to pinpoint problems with their colonies, but also track ambient levels of pesticide pollution in a community. According to a study published by an international team of researchers, APIStrip has the potential to detect 442 pesticides as well as their primary break down products at levels lover than parts per billion. The strip, comprised of polymer, is what scientists describe as “a bee-proof, in-hive passive sampler.” Current methods of sampling honey bee hives for contaminants is time-consuming, requiring removal of bees, pollen, honey or beeswax, and can result in significant hive disturbance. This new method was piloted by citizen-science beekeepers, and according to researchers proved to be a simple and effective tool that any interested citizen-scientist could employ. Passive sampling of environmental contaminants by citizen scientists […]

(Beyond Pesticides, June 23, 2020) Next-generation systemic insecticides, billed by the agrichemical industry as “safer for bees” than neonicotinoids, have been found to stress and kill honey bees. As reported, a study by researchers at Oregon State University in the journal PLOS One, sulfoxaflor and flupyradifurone (in the products Transform and Sivanto, respectively) were found to increase apoptosis (cell death) and increase oxidative stress in exposed honey bees. The study indicates that, “With the recent Environmental Protection Agency (EPA) approval for use of both flupyradifurone and sulfoxaflor, and with the growing concern regarding pollinator health, it is important to better understand any potential negative impacts (especially sub-lethal) of these pesticides on bees.” However, this statement begs the question ‘why these two new bee-toxic pesticide were approved by EPA in the first place.’ This process is familiar and frustrating to those who continue to fight against the decline of pollinators: the chemical industry introduces and EPA approves new toxic pesticides marketed as “safer” to the specific problem caused by its older products, only to find out through independent and academic research that the problem is not solved in the least. Researchers conducted two exposure assessments: one six-hour long study, and another […]

(Beyond Pesticides, May 27, 2020) Research published last week in the journal Scientific Reports uncovers new ways that neonicotinoid (neonic) insecticides hamper the growth and development of honey bee colonies. As new data on the link between neonics and pollinator declines continues to flow from academic institutions, the U.S. Environmental Protection Agency (EPA) has re-opened the public comment period on its proposal to renew the registration of these highly toxic insecticides. The present study, led by German scientists at Goethe University Frankfurt am Main, uses new video techniques to observe the behavior of honey bees behind a glass-pane hive. Researchers filmed their study from start to finish, focusing on the effect of chronic sublethal doses of the neonciotinoids clothianidin and thiacloprid. Colonies were fed these chemicals in a sugar syrup over the course of three weeks in May and June. Even at low levels, scientists found significant changes to brood rearing and development, and the behavior of nurse bees. Nurse bees play a pivotal role in honey bee colonies. These young worker bees clean out old brood cells (where larvae develop), feed larval bees after a queen lays its eggs, and finish by capping a brood cell with wax. Within […]

(Beyond Pesticides, April 9, 2020) Honey bees (Apis mellifera) remain in severe decline, with U.S. beekeepers losing 30% of their managed colonies each year. A Texas A&M University (Dr. Juliana Rangel’s laboratory)  study provides evidence that chemical-intensive farming practices contaminate honey bee hives with pesticides that cause developmental delays. Researchers found that toxic pesticides adversely affect honey bee queen physiology and worker bee performance. Moreover, pesticides exacerbate the health risks associated with the declining honey bee population. When maturing honey bees’ exposure to pesticides is limited, there is an improvement in honey bee queen health and colony behavior. In agricultural settings, honey bees are exposed to an amalgamation of pesticides. AAFC and Texas A&M researchers determined which pesticides (miticides, insecticides, and fungicides) are commonly used in combination and then used those pesticide combinations to expose honey bees to field-realistic doses in the lab: tau-fluvalinate and coumaphos, amitraz, or chlorothalonil and chlorpyrifos. Researchers cultivated maturing honey bee queens in plastic cups coated with either pesticide-free or pesticide-contaminated beeswax. Honey bee queens were transferred into hives upon maturation and bred naturally. Researchers measured their egg-laying frequency along with worker bee entourage size. Post-reproduction, scientists performed a bioassay (a measurement of substance potency or concentration effects on living cells) on […]

(Beyond Pesticides, February 21, 2020) Last week in Minnesota, state Representative Jean Wagenius introduced measure H.F. 1255 that would give cities the opportunity to ban local use of bee-lethal pesticides. This is the latest in a series of attempts to fight state pesticide preemption, an industry-promoted law that prevents localities from restricting pesticide use more stringently than the state. In the face of inaction at the federal and state levels, advocates and legislators in Minnesota are attempting to regain local control to help save their declining, Midwestern pollinators. Representative Wagenius says about the measure, “Minnesotans should be able to protect pollinators if they want to. We value local control in this state, and we always have.” H.F. 1255 will allow cities to opt into a blanket ban of pesticides determined by the Environmental Protection Agency (EPA) to be hazardous to bees. Pesticides with an EPA bee-advisory box are listed on the state’s Department of Agriculture website and referred to as “bee-lethal” by Minnesota legislators. Patrick Hanlon, director of environmental programs for the city of Minneapolis, says cities would work with Department of Agriculture, businesses, and residents that might be impacted by these restrictions before enacting the bill. Local advocates have […]

(Beyond Pesticides, January 28, 2020) The practice of coating seeds with insecticides, now widely adopted as a result of the agrichemical industry, has created increasingly toxic conditions for pollinators foraging on US cropland, finds a study published in Scientific Reports by Penn State University scientists. The data finds that even as overall volume of insecticide use has decreased, the total “bee toxic load” – a term branded by researchers – has increased markedly due in large part to the use of hazardous seed coatings. The switch from one toxic chemical to another is indicative of a chemically-driven agricultural system that, in order to reverse insect, pollinator and bird declines, must undergo rapid changes over the next several decades. Researchers used information from multiple US databases to determine regional patterns in pesticide use and corresponding toxicity loads to pollinators. Thus the term “bee toxic load” was determined by combining the area of land where insecticides were applied with the total toxicity of the particular insecticide used. To compare the impact of changes in the mode of action of the insecticides used, toxicity data was separated between oral and contact toxicity.    Findings indicate that from 1997-2012, contact bee toxic load remained […]

(Beyond Pesticides, December 10, 2019) Thousands of fox, coyote, and other carnivores will continue to be poisoned to death by hydrogen cyanide after the Trump Administration’s Environmental Protection Agency (EPA) re-approved the use of M-44 “cyanide bombs” earlier this month. Cyanide bombs are essentially small, poison-filled land mines baited with food and placed on rural land with the intent of killing predators that prey on grazing livestock.  “EPA is blatantly ignoring its fundamental duty to protect the public, our pets and native wildlife from the cruel, lethal impacts of cyanide bombs lurking on our public lands,” said Kelly Nokes, an attorney with the Western Environmental Law Center (WELC). “We will continue to hold our federal government accountable to the law, and will continue our fight for a ban on M-44s once and for all.” After denying a petition to ban the products last year, the agency delayed a decision to reregister M-44s in response to over 20,000 public comments, 99.9% of which opposed renewal, according to an analysis by the Center for Biological Diversity and WELC. Despite overwhelming public opposition, EPA Administrator Andrew Wheeler is renewing the products with only minor changes to the labels that govern their use. The […]
