(Beyond Pesticides, February 7, 2018) New data from the California monarch butterfly count indicate that the western population of the species is continuing to decline at an alarming rate, with scientists and conservation groups pointing to man-made factors like logging, climate change, and herbicide use on genetically engineered (GE) crop fields as primary drivers. The annual California count of western monarch butterflies stationed volunteers at 262 sites, more than ever before, yet at 200,000 butterflies counted, the numbers nearly matched the lowest level recorded this decade, when only 145,000 butterflies were seen in 2012. The decline of these iconic butterflies demands swift action from lawmakers and regulators to protect their dwindling numbers. Dramatic declines in monarch populations mirror continuing declines in honey bees and other wild pollinator species. Species declines may be even broader than pollinators, affecting all insects in general. Research from Germany recently found that insect abundance declined 75% over the last 30 years, owing the results primarily to agricultural intensification. The western population of monarch butterflies – those found west of the Rocky Mountains – overwinter in coastal California forests. Throughout the warmer months, female butterflies will lay eggs only on milkweed, making these plants critical to […]

(Beyond Pesticides, January 31, 2018) Woolworths, one of Australia’s largest retailers, has decided to stop selling neonicotinoid products (neonics) linked to global declines in bee populations. This is the latest retailer in Australia to announce commitments to stop supplying the bee-toxic products. After thousands of Australians signed a petition calling on retailers to stop selling insecticides containing neonicotinoids, Woolworth announced it has, in fact, succumbed to public pressure and would join Bunnings Warehouse, Mitre 10 and Coles stores in pulling neonic products from their shelves. The week prior, retail chain Bunnings announced it would pull all items containing neonicotinoids from their shelves. Woolworth said it would stop selling the products by June 2018. The retail commitments come as a result of efforts launched by global consumer group SumOfUs that called on Australian retailers to stop selling insecticide products containing neonicotinoids, including the popular home and garden product, Confidor, which has been stocked by Woolworths and contains imidacloprid as the active ingredient. According to Australia’s The New Daily, about one-third of Australian fruit and vegetable crops are reliant on pollination. Speaking on the ban of neonic products, Katja Hogendoorn, PhD, of University of Adelaide, who researches the behavioral ecology and evolution of native bees, […]

(Beyond Pesticides, January 30, 2018) New data from the U.S. Geological Survey (USGS) reveals the year-round presence of neonicotinoids (neonics) in the Great Lakes – the world’s largest freshwater ecosystem. Neonics, which are highly toxic to aquatic organisms and pollinators, are prevalent in the tributaries of the Great Lakes with concentrations and detections increasing during planting season. This new data adds to burgeoning demand for a federal ban of these insecticides in order to safeguard vulnerable aquatic ecosystems and pollinators. The study, “Year-round presence of neonicotinoid insecticides in tributaries to the Great Lakes, USA,” sampled ten major tributaries to the Great Lakes from October 2015 to September 2016. Neonicotinoids were detected in every month sampled. At least one neonicotinoid was detected in 74 percent of the samples, with 10 percent of samples containing three neonicotinoids. The most frequently detected neonicotinoid was imidacloprid (53%), followed by clothianidin (44%), thiamethoxam (22%), acetamiprid (2%), and dinotefuran (1%). The detections of clothianidin and thiamethoxam are significantly correlated with the percentage of agricultural land use. Similarly, concentrations increased in the spring and summer months when the planting of neonic-coated seeds and broadcast applications are the highest. For instance, in the agriculturally dominated basin (corn and soybean) […]

(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 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 12, 2018) Honey bees display a concerning attraction to the herbicide glyphosate and the fungicide chlorothalonil at certain concentrations, new research from scientists at the University of Illinois (UIL) reveals. Results are reminiscent of a 2015 study published in the journal Nature, which found that honey bees display a preference for foods treated with neonicotinoids, a class of insecticides implicated in global pollinator declines. Since the crisis became public knowledge in 2006, managed honey bees have experienced unsustainable levels of colony loss, and one in four species of native bees in North America and Hawaii are at risk of extinction. This new research adds to growing concerns that, while neonicotinoids continue to play a primary role in the pollinator crisis, their elimination would still leave a myriad of other toxic chemical threats to the recovery of these critical species, upon which so much of our food supply relies. UIL scientists investigated honey bees’ preference for a range of pesticides as well as a number of naturally occurring chemicals that honey bees would likely encounter in the field. In the experiment, pollinators were put in a large enclosure and allowed to fly to different feeders stocked with either […]

(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 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 11, 2017) Tell the Natural Resources Conservation Service (NRCS) to substantially increase the amount of funding spent on the conservation of monarch butterflies and the restoration of their habitat, and to ensure that restored habitat is not poisoned with hazardous pesticides. Although the agency has taken some steps to protect monarchs –including the implementation of the Monarch Butterfly Habitat Development Project and support for the Monarch Butterfly Conservation Fund— last year’s NRCS expenditure of $4 million was insufficient to prevent the monarchs’ decline, and could not even begin stemming the loss of milkweed habitat. Restoring the monarch butterfly and its habitat will require a substantial contribution from the agricultural sector and strong leadership from the NRCS. Agricultural lands encompass 77% of all prospective monarch habitat, and thus are indispensable to reaching these goals. Monarch populations have fallen more than 80 percent over the last 20 years, and it is estimated that there is a 60 percent chance the multigenerational migration of these butterflies would completely collapse in the next 20 years. Milkweed, the only forage for monarch caterpillars, has decreased by 21 percent, especially in the Midwest, where agricultural fields and pesticide use have expanded. Scientists estimate […]

(Beyond Pesticides, December 8, 2017) Less toxic oil-based insecticides are showing promise for the treatment of bed bugs, according to a study published this month in the Journal of Economic Entomology. The common bed bug has seen a significant resurgence in the U.S., and with the pests found to be resistant to a broad range of modern, toxic insecticides, pest control operators are searching out new, safer ways to manage infestations. “So far there are no reports of resistance to these oils,” said study author Changlu Wang, PhD to Entomology Today. “It is very difficult for insects to develop resistance to them since they are not neurotoxins.” A range of 18 essential oils, concentrated liquids containing aromatic compounds derived from plants, were tested for their toxicity to bed bugs that were retrieved from an infested building in Indiana. Paraffin oil, a colorless and odorless mineral oil, as well as three silicone oils, similarly colorless and odorless oils used in various personal care products and medications, were also screened for their toxicity to bed bugs. Scientists observed the bed bugs in a laboratory setting for two weeks before moving to another round of experimentation. Of the 22 oils tested, paraffin oil […]

(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 5, 2017) Fungicides are likely playing an important role in the decline of North American bumblebee populations, according to new research published by a team at Cornell University. While overwhelming data continue to indicate that insecticides, particularly the neonicotinoid class of chemicals, are the leading factor in overall pollinator declines, Cornell scientists discovered that fungicides, in particular the chemical chlorothalonil, are likely compounding risk and toxicity for U.S. bumblebee species. As new studies continue to expand the chemical culprits in pollinator declines, calls for a wholesale change in agricultural practices toward more sustainable organic production are reinforced. Cornell researchers began their investigation by focusing on what land use factors had the most impact on eight bumblebee species, many of which have been declining in the U.S. Bumblebee species were sampled at nearly 300 sites in 40 states during the summer months, and at each of the sampling sites, landscape variables were characterized and quantified for land use (urban v rural), habitat (high vs low latitude), and pesticide (insecticide, fungicide, herbicide) usage. The strongest indicator of declining range within the selected bumblebee species was found to be overall fungicide use, with those in the northern U.S. undergoing the […]

(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 28, 2017) Bumblebees exposed to field-realistic levels of neonicotinoid insecticides have problems with “buzz pollination” that results in reduced pollen collection, according to new research published in Scientific Reports. This is the latest science to tease out the complex ways in which neonicotinoids interfere with these important pollinators, providing yet another reason to eliminate these highly toxic, systemic insecticides from the environment. Flowers that bumblebees pollinate require the insects to emit soundwaves, or ‘sonicate’ to release their pollen, and bumblebees must perfect their techniques over time in order to maximize the pollen they are able to collect. Researchers tested the effect of neonicotinoids on bumblebees’ sonication abilities by exposing them to field realistic doses of the insecticide thiamethoxam at rates of 2 parts per billion (ppb) and 10 ppb, and observing their ability to successfully collect pollen. A control group that never came in contact with thiamethoxam was also used to compare the progress of the exposed group. Lead author of the study, Penelope Whitehorn, PhD, indicated, “We found that control bees, who were not exposed to the pesticide, improved their pollen collection as they gained experience, which we interpreted as an ability to learn to buzz […]

(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 20, 2017) The pesticide industry is drafting legislation that threatens to remove provisions of the Endangered Species Act that protect species from pesticides. Tell your Congressional delegation to oppose all efforts to reduce endangered species protections from pesticides. The Endangered Species Act (ESA) is one of America’s most effective and important environmental laws. It represents a commitment to protect and restore those species most at risk of extinction. Recent polling shows 84 percent of Americans support the Endangered Species Act, and 87 percent agree that it is a successful safety net for protecting wildlife, plants, insects, and fish from extinction. Although many species –including the bald eagle, Florida manatee, and California condor— have been protected and brought back from the brink of extinction under the ESA, an estimated 500 species have disappeared in the past 200 years. An important provision of the ESA is the requirement that each federal agency that proposes to authorize, fund, or carry out an action that may affect a listed species or its critical habitat must consult with the U.S. Fish and Wildlife Service and National Marine Fisheries Service. In the case of pesticides, EPA is required to perform such a consultation if […]

(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 24, 2017) Over 75% of insect abundance has declined over the last 27 years, according to new research published by European scientists in PLOS One. The dramatic drop in insect biomass has led to equally dramatic pronunciations from highly respected scientists and entomologists. “We appear to be making vast tracts of land inhospitable to most forms of life, and are currently on course for ecological Armageddon,” study coauthor David Goulson, Ph.D. of Sussex University, UK, told The Guardian. “If we lose the insects then everything is going to collapse.” Looking at the range of mechanisms that could be driving this slow moving catastrophe, researchers could suss out only one plausible large-scale factor: agricultural intensification. The current study, which looked at 63 nature preserves located in Germany, follows a similar study released in 2013 that was conducted in a singular German nature preserve. That study, originally published only in German, but available translated by Boulder County Beekeepers, found that 75% of insect biomass declined in the Orbroich Bruch Nature Reserve in Krefeld, Germany from 1989 to 2013. That study was limited to a singular nature preserve, and while scientists who worked on the study described their results as […]

(Beyond Pesticides, October 23, 2017) Willapa Bay and Grays Harbor, with a number of unique ecosystems, and among the most important estuaries in the U.S, are once more in danger of being sprayed with the toxic neonicotinoid insecticide imidacloprid. A draft Supplemental Environmental Impact Statement (SEIS) produced by the Washington State Department of Ecology (Ecology) considers two options for spraying imidacloprid and one no-action alternative. Imidacloprid would be sprayed to kill the native burrowing shrimp in beds of commercial Japanese oysters. Tell Ecology to restore the bays instead of spraying them! Ecology’ssummary highlights: ⦁    Immediate adverse, unavoidable impacts to juvenile worms, crustaceans, and shellfish in the areas treated with imidacloprid and the nearby areas covered by incoming tides. ⦁    Limited impacts bay-wide, but significant uncertainty about the cumulative impacts and other unknown impacts, including those to other marine invertebrates and lifecycles. ⦁    Little direct risk to fish, birds, marine mammals, and human health. ⦁    Potential indirect impacts to fish and birds if food sources are disrupted. ⦁    Continued knowledge gaps about imidacloprid. Further research is needed. The SEIS fails to give adequate weight to the “knowledge gaps” it identifies, in some cases indicating that monitoring during use of imidacloprid could be used […]

(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 […]
