(Beyond Pesticides, July 31, 2015) New information has surfaced regarding the role of agrochemical giants Bayer and Syngenta in the United Kingdom (UK)’s recent decision to temporarily allow the use of neonicotinoid seed treatment on oilseed rape crop. A record of the meeting, involving the UK government’s expert committee on pesticides (ECP) and industry representatives, had previously been suppressed. The newly released record of the meeting shows that Bayer and Syngenta were the only external representatives asked to answer the ECP’s questions. The emergency use, which has been granted for 120 days, allows growers to use Bayer’s Modesto (clothianidin) and Syngenta’s Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals known as neonicotinoids  (neonics), which have been  linked  to pollinator decline. These pesticides are associated with  decreased learning,  foraging  and navigational ability in bees, as well as increased vulnerability to pathogens and parasites as a result of suppressed bee immune systems. Used widely in agriculture as seed treatment for various crops, foraging bees, in the absence of their native habitat, are exposed to fields of poison where even pollen and nectar are contaminated. In addition to toxicity to bees, neonicotinoids have been shown […]

(Beyond Pesticides, July 28, 2015) Data published from the Harvard School of Public Health reveals  neonicotinoids (neonics), a class of chemicals implicated in the global decline of honey bees and other pollinators, in over 70% of both pollen and honey samples collected throughout the state of Massachusetts during months when bees are most actively foraging. The results of this study have grave  implications for pollinator health, as even minute, near-infinitesimal doses of neonics can cause sublethal impacts that compromise the health of entire bee colonies. The Harvard study, led by Chensheng (Alex) Lu, PhD, and published in the Journal of Environmental Chemistry, took monthly honey and pollen samples from 62 volunteered bee hives between April and August 2013. The 219 pollen and 53 honey samples were then analyzed for the presence of eight neonic insecticides. Every month, in every location, researchers found neonics in the pollen and honey collected by bees. In total, 73% of pollen samples and 72% of honey samples contained at least one neonicotinoid at levels which could result in sublethal harm. While previous studies have tested the presence of neonics at a single point in time, this is the first study to show the long-term persistence […]

(Beyond Pesticides, July 13, 2015) Many factors have been identified in bee and other pollinator decline across the globe, including loss of habitat, disease, and pesticides. A  new study from researchers in North American and Europe finds that the  changing climate also plays a vital role in decreasing bee habitat and thus reducing populations. The study reports that North American and European bumble bees are unable to colonize new warmer habitats north of their historic range, while simultaneously disappearing from the southern portions of their range. Published in Science, the study,  Climate change impacts on bumblebees converge across continents,  which is a comprehensive look at 67 bumblebee species and their territories over the last century, finds that many North American and European bumblebees have retreated from the southern edge of their historic ranges (away from the equator). While other species of animals have been able to adapt to climate change by expanding their habitats, bumblebees have not shifted to warming northern climes and are experiencing shrinking distributions in the southern ends of their range. The rusty patched bumblebee (Bombus affinis), for instance, has disappeared from parts of the southeastern U.S. Bumblebees are also retreating to higher elevations, shifting upward by […]

(Beyond Pesticides, June 30, 2015) As the Monarch butterfly suffers serious decline, the U.S. Environmental Protection Agency (EPA) is considering  the role of  herbicides in killing the iconic species’ food source, milkweed, and developing an action plan that may fall short. The agency identified possible action that it may take to slow the Monarchs’ decline in a document released last week entitled Risk Management Approach to Identifying Options for Protecting the Monarch Butterfly (Monarch Approach document). EPA’s approach to Monarch conservation comes shortly after the White House released its National Pollinator Health Strategy, intended to “reverse pollinator losses and help restore populations to healthy levels.” The U.S. Fish and Wildlife Service is also in the midst of conducting a review of the Monarch butterfly to determine whether the species is eligible for protection under the Endangered Species Act. The number of Monarchs reaching their winter breeding grounds in Mexico has fallen by 90% in less than 20 years. This year’s population was the second lowest since surveys began two decades ago. The critical driver of this decline has been linked to the loss of milkweed, the only plant on which Monarchs will lay their eggs, along their migration route, which […]

(Beyond Pesticides, June 29, 2015) A recent study has provided supporting evidence to previous work showing that sublethal doses of imidicloprid, a toxic neonicotinoid insecticide, impairs olfactory learning in exposed honey bee workers. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have experienced ongoing and rapid population declines. The science has become increasingly clear that pesticides (especially the neonicotinoid class of insecticides), either acting individually or synergistically, play a critical role in the ongoing decline of honey bees and wild pollinators. Neonicotinoids can be persistent in the environment, and have the ability to translocate into the pollen and nectar of treated plants. “Honeybees need to learn to associate nectar reward with floral odor. One of the main reasons why flowers produce odor is so that this odor can be learned by pollinators and used to repeatedly visit the same flower species. Without this repeat visitation, pollination does not occur. We showed that a neonicotinoid pesticide, at sublethal doses, harms this odor memory formation,”  Chinese Academy of Science’s Ken Tan, who led the study, told CBS News in an email interview. Published in Nature on June 18, 2015, the study finds that “adults that ingested […]

(Beyond Pesticides, June 24, 2015) The International Agency for Research on Cancer (IARC) has found that there is some evidence in experimental animals that the popular herbicide, 2,4-D, is linked to cancer and now classifies it as a Group 2B, “possibly carcinogenic to humans.” IARC also classified lindane, used commonly in the U.S. as a topical lice treatment, in Group 1,“carcinogenic to humans” based on sufficient evidence in humans with the onset of non-Hodgkin lymphoma (NHL). These latest cancer findings come just months after the agency classified the world’s most widely used herbicide, glyphosate (Roundup), as “probably carcinogenic to humans,” raising public concerns on the lack of action from U.S. regulators. This month, 26 experts from 13 countries met at the World Health Organization’s (WHO) IARC in Lyon, France to assess the carcinogenicity of the insecticide lindane, the herbicide 2,4-D, and insecticide DDT. The findings are published in the Lancet. The new IARC findings come months after the agency classified glyphosate, the ingredient in the popular Roundup weed killer, as a Group 2A “probable” carcinogen, citing sufficient evidence of carcinogenicity based on laboratory studies. This decision sparked renewed calls for the U.S. Environmental Protection Agency (EPA) to take action on […]

(Beyond Pesticides, June 22, 2015) Two new studies raise concerns over the connection between the use of fungicides and the declining overall health of bee colonies. While  the use of neonicotinoid insecticides has been established as a  primary contributor  to declining pollinator populations, these new studies shine a light on the use of fungicides and the negative impacts their use has on overall bee health. The first study was performed after a group of local farmers asked researchers at the University of Wisconsin to assess whether it was safe to spray fungicides on crops while they are in bloom and bees are foraging. Because insecticides, like neonicotinoids, are meant to kill insects, researchers have performed numerous studies on how the use of these insecticides may harm beneficial insects as well as those they are intended to target. Fungicides, however, are not meant to kill insects, so the relationship between their use and effects on bee populations is relatively unstudied. Researcher Hannah Gaines Day, Ph.D., an entomologist at the University of Wisconsin, cautions that her team’s study, which involved five bumblebee colonies kept in field enclosures where flowers were sprayed with field-realistic doses of chlorothalonil, a  common fungicide, was small and […]

(Beyond Pesticides, June 16, 2015) France’s Ecology Minister Segolene Royal announced Sunday a  call to  stop  the sale of the popular Monsanto herbicide Roundup (glyphosate) from garden centers. The announcement comes just a couple of  months after the active ingredient, glyphosate, was classified in March as “probably carcinogenic to humans” by the United Nation’s International Agency for Research on Cancer (IARC). “France must be on the offensive with regards to the banning of pesticides,” Royal said on French television. “I have asked garden centers to stop putting Monsanto’s Roundup on sale” in self-service aisles, she added. The announcement comes after a request by French consumer association CLCV (Consumption, Housing and Environment – Consommation, Logement et Cadre de vie)  to French and European officials to stop selling glyphosate-based products to amateur gardeners. Royal also announced last week that from January 2018 onwards, phytosanitary products —used to control plant diseases— would only be available to amateur gardeners “through an intermediary or a certified vendor.” Glyphosate is touted as a “low toxicity” chemical and “safer” than other chemicals by EPA and industry and is widely used in food production and on lawns, gardens, parks, and children’s playing fields. However, IARC’s new classification of […]

(Beyond Pesticides, June 1, 2015) Last week, the Environmental Protection Agency (EPA) released a proposal intended to create “physical and temporal space” between bees and toxic pesticides. While touted as monumental progress on bee health by the agency, the reality is that the proposal will only result in modest changes to pesticide labels. EPA’s new rules contain only a temporary ban on foliar applications of acutely bee-toxic pesticide products, including neonicotinoid class insecticides, during bloom and when a beekeeper is on site and under contract. The proposal doesn’t address the widespread contamination and detrimental effects of these toxic, systemic (whole plant poisons) chemicals that will continue to occur even during the temporary prohibition. Media reports have generally overstated the implications of the proposal, applauding the “new” restrictions, and labeling the small portion of agricultural land that is affected  as “pesticide-free zones,” which couldn’t be further from the truth. The restrictions are not anything new — EPA pesticide labels already prohibit applications while in bloom where bees are foraging. Neal Bergman, a commercial beekeeper in Missouri, said in a statement to the St. Louis Post-Dispatch that the proposal is “basically enforcing label guidelines,” further highlighting the fact that EPA has failed […]

(Beyond Pesticides, May 27, 2015) As summer approaches, local stores continue to set the pace for protecting pollinator populations from the harms of neonicotinoid pesticide use. In southern Maine, Kittery Ace Hardware joins Eldredge Lumber and Hardware in its efforts to actively seek alternatives to  pesticides that contain  neonicotinoids and other toxic pesticides by consciously stocking their shelves with organic compatible products as opposed to lawn and garden products that contain toxic chemicals. This shift by local stores like Eldredge and Kittery highlights the role retailers can play in responding to community concerns over dangerous pesticide use, and indicates their desire to be part of the solution when it comes to protecting pollinators. Local stores’ increasing  attention to local concerns over a common problem is  juxtaposed with  big box hardware stores’ response to neonicotinoid concerns that respond to public pressure with vague language, drawn out or nonexistent timelines, and failure to take a stance on overwhelming scientific evidence that neonicotinoids cause harm to pollinator populations. As more national retailers respond to public pressure to ban neonicotinoid-containing products, it becomes clear that local, small-scale efforts to stock shelves with alternative products offer a better and more concrete approach to stopping neonicotinoid […]

(Beyond Pesticides, May 26, 2015) A study led by Purdue University Entomology Professor Michael Scharf, Ph.D. finds that small doses of imidacloprid, a neonicotinoid pesticide, can halt the normal functioning of termite behavior, leaving colonies vulnerable to disease and eventual death. While this effect may be celebrated by the pesticide industry as a victory for termite control, it has serious implications for the use of imidacloprid and other neonicotinoid pesticides on all eusocial insects, such as ants and bees. Eusocial insects thrive as a colony, working, living and sometimes even fighting diseases as one organism, rather than as many individuals existing together. Termites, specifically, exhibit a remarkable resistance to many diseases because they engage in social grooming, clearing pathogens off of one another. Other examples of eusociality can be found in ant and bee colonies. Ant colonies create foraging trails and engage in cooperative transport, where they create long chains of ant individuals to form a whole assembly line to transport food back to the colony and work as one to carry large prey that would not be otherwise attainable. Honeybee colonies send out foragers to report back with the location of plentiful food sources so that other bees know […]

(Beyond Pesticides, May 14, 2015) For the first time on record, summer losses of managed honey bee colonies have exceeded winter losses, according to preliminary results of the annual survey released yesterday by the Bee Informed Partnership, the U.S. Department of Agriculture (USDA) and the Apiary Inspectors of America. This is the second highest annual loss recorded to date: beekeepers lost a total of 42.1 percent of the number of colonies managed over the last year (total annual loss, between April 2014 and April 2015), which is up from 34.2 percent for the previous year. On the same day that this survey was released, the  U.S.  House Agriculture Subcommittee on Horticulture, Biotechnology and Research held a hearing on pollinator health, but failed to advance policy solutions that would protect pollinators from the unnecessary use of pesticides. “What we’re seeing with this bee problem is just a loud signal that there’s some bad things happening with our agro-ecosystems,” Keith Delaplane, PhD at the University of Georgia and one of the co-authors of the study told Phys.Org. “We just happen to notice it with the honeybee because they are so easy to count.” About two-thirds of the beekeepers responding to the survey […]

(Beyond Pesticides, May 1, 2015)  A recent success in grassroots activism  comes through Tracy Madlener, a mother of two, who got  her neighborhood in Laguna Hills, California to eliminate the use of Roundup, a widely-used weedkiller. The International Agency for Research on Cancer (IARC), an intergovernmental agency forming part of the World Health Organization (WHO) recently classified Roundup’s active ingredient, glyphosate, as carcinogenic in people based on animal studies. The classification is technically “probably carcinogenic to humans (Group 2A),”  sufficient evidence of carcinogenicity based on laboratory studies. Gravely concerned, Ms. Madlener began her mission to eliminate the use of toxic  Roundup in her neighborhood, with some help from Beyond Pesticides, sharing her progress on a new Facebook page ”˜How to Create a Toxic-Free Community’  along the way. Just five days in she posted a video blog about getting started: organizing, sending emails, making a to-do list, and making phone calls for research purposes. She also built up a network and informed  others in the area, contacted other moms doing similar work to ban harmful chemicals in their areas for advice, spoke with landscapers to  suggest healthier options, researched environmentally- and health-conscious alternatives to Roundup for local use, and made folders […]

(Beyond Pesticides, April 24, 2015) Two new studies reporting on the adverse effects of neonicotinoids on bees were published Wednesday in the journal Nature, adding to a growing body of scientific literature linking the controversial class of pesticides to the global decline in bee populations. The conclusions reached by the two studies find that not only does neonicotinoid exposure result in reduced bee density, nesting, colony growth, and reproduction, but also that bees in fact prefer foods containing neonicotinoid pesticides despite their adverse effects. Neonicotinoids affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sublethal exposure that causes  changes in bee reproduction, navigation, and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees. Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites, and other diseases, and leading to devastating bee losses. In one study, “Seed coating with a neonicotinoid insecticide negatively affects wild bees,” Swedish scientists report that wild bees […]

(Beyond Pesticides, April 6, 2015) Last week, the city council of Portland, Oregon voted unanimously to ban the use of neonicotinoid insecticides on city-owned property because these pesticides are persistent in the environment, harmful to pollinators, and have been involved in acute bee kills in other areas of the state. Neonicotinoids affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sublethal exposure that causes  changes in bee reproduction, navigation, and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees.   Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites, and other diseases, and leading to devastating bee losses. Portland’s ordinance was spurred in part by the 2013 deaths of tens of thousands of bees as a result of the improper use of the neonicotinoids. Last month state officials banned  four   of the bee-killing insecticides, including   imidacloprid, clothianidin, thiamethoxam and dinotefuran from  use on  Linden  trees. In addition to […]

(Beyond Pesticides, March 16, 2015) Last week, a judge in Duesseldorf Regional Court ruled that the German branch of Friends of the Earth (BUND) has a right to speak out against chemical company giant Bayer CropScience’s neonicotinoid pesticide, thiacloprid, regarding its potential danger to bees. The court considered the allegations put forth by BUND to be a form of free speech, a protected right. Neonicotinoids, a class of insecticides, affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sub-lethal exposure causing changes in bee reproduction, navigation and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees. Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites and other diseases, leading to devastating bee losses. Thiacloprid is one of the seven most commonly used neonicotinoids. It is used to control sucking and biting insects in cotton, rice, vegetables, pome fruit, sugar beet, potatoes and ornamentals. Low doses of neonicotinoids are considered highly […]

Congress heeds call to action and introduces legislation as pressure mounts on White House Task Force to issue meaningful recommendations March 4, 2015 (Washington, DC)””A coalition of beekeepers, farmers, business leaders, environmental and food safety advocates rallied in front of the White House and delivered more than 4 million petition signatures today calling on the Obama administration to put forth strong protections for bees and other pollinators. This action anticipates the Pollinator Health Task Force recommendations, expected later this month. The task force, announced by the White House this past June, is charged with improving pollinator health through new agency regulations and partnerships. The assembled groups demand that the recommendations include decisive action on rampant use of neonicotinoids, a class of systemic insecticides scientists say are a driving factor in bee declines. The rally coincided with both a D.C. metro ad campaign and Representatives Earl Blumenauer (D-OR) and John Conyers’s (D-MI) reintroduction of the Saving America’s Pollinators Act, which would suspend the use of four of the most toxic neonicotinoids until the Environmental Protection Agency (EPA) conducts a full review of their safety. Representative Blumenauer, said, “Pollinators are not only vital to a sustainable environment, but key to a stable […]

The 33rd National Forum provides an opportunity to share the current science and policy information and discuss local, state, and national issues. The conference, including a tour in […]

(Beyond Pesticides, January 14, 2015)””More than 100 businesses, including Clif Bar, Nature’s Path, Organic Valley and Stonyfield, sent a letter to the White House yesterday urging it to immediately suspend pesticides linked to global bee declines in order to protect the nation’s food supply, environment and economy. The businesses, members of the American Sustainable Business Council (ASBC) and Green America’s Green Business Network, voiced concerns about the U.S. Environmental Protection Agency (EPA)’s delays in restricting neonicotinoids, the world’s most widely-used insecticides. Many of the 118 businesses that signed the letter sell products with ingredients or inputs that are dependent on pollination from bees and other pollinators, including fruits, vegetables, nuts, seeds, fiber (such as cotton) and hay (including alfalfa grown to feed livestock). The businesses call on the EPA to immediately suspend the registrations of neonicotinoids for agricultural uses, including seed treatments, as well as cosmetic and other unnecessary uses pending the results of pesticide re-evaluation. They also called for increased investments in green, fair and cutting-edge alternatives to neonicotinoids that support a prosperous and sustainable agricultural system. “We are very concerned about the continued and unsustainable losses of bees and other essential pollinators and what effects this will have […]

(Beyond Pesticides, November 5, 2014) New research from Pennsylvania State University reports that pesticides cause large changes in the expression of genes involved in detoxification, immunity and nutrition-sensing in bees, adding to previous research that has found that pesticides compromise bee immune function. This research also finds that bees with a diet of natural, high quality pollen exhibit greater resistance to pesticides’ deleterious effects than bees on an artificial diet. The new study, “Genomic analysis of the interaction between pesticide exposure and nutrition in honey bees (Apis mellifera),” finds that pesticide exposure can impact the expression of genes that are sensitive to diet and nutrition. The researchers, upon feeding honey bees either the miticidal pesticides, coumaphos or fluvalinate, for a period of seven days, noticed significant changes in 1,118 transcripts – or strands of RNA – in the experimental group. The transcripts include genes involved in detoxification, immunity, and nutrition. The authors report that there is substantial overlap in responses to pesticides and pollen-containing diets at the genetic level. Subsequent analyses demonstrate that pollen-based diets reduce the honey bees’ susceptibility to pesticide stress verses an artificial diet – e.g. a soy protein or no protein diet. Thus, the researchers note […]

(Beyond Pesticides, October 20, 2014) The U.S. Environmental Protection Agency released a report Thursday that soybean  seed treatments with neonicotinoid insecticides provide little or no overall benefits in controlling insects or improving yield or quality in soybean production. While pesticide manufacturer Syngenta has petitioned EPA to raise the allowable levels of another systemic pesticide thiamethoxam on a number of crops, EPA’s report confirms  scientific findings  that these chemical treatments are unnecessary and inefficacious. Widely used neonicotinoids, which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies and by beekeepers  as the major contributing factor in bee decline. The report concludes that not only is there no increase in soybean yield when compared to using no pest control at all, but also the potential benefit of neonicotinoid seed treatment is not likely to be large or widespread throughout the U. S. EPA also found that seed treatments fail to provide protection from target pests during critical times of plant activity, ultimately leading to the assessment that “much of the existing usage on soybeans is prophylactic in nature.” “This report demonstrates, yet again, the need for […]

(Beyond Pesticides, October 14, 2014) Though pollinators only account for about 10% of the production of food crops worldwide, pollinator decline could play a disproportionate role in affecting human health in regions that are already facing food scarcity, according to a new study. Global malnutrition overlaps with pollinator-dependent micronutrient production, published last month in the Proceedings of the Royal Society B. The study  examines regional differences in pollinator dependence of the micronutrient content in crops, revealing a significant overlap between this dependency and the severity of nutrient deficiency. Previous research has underscored the importance of pollinators to agriculture in the U.S., finding that their services are essential to crop yields,  A  May 2013 report by the U.S. Department of Agriculture (USDA)  found that one in three bites of food depends on pollination, mainly by honey bees, and that pollination is valued at $20 to $30 billion annually. For the study, scientists collected data on nutrient contents, pollination dependence and regional agricultural yields for more than 100 of the most common crops grown for global consumption. Combining that data with USDA nutritional information, they were able to determine that three essential nutrients were dependent on pollinators, vitamin A, iron and folate. […]

(Beyond Pesticides, September 16, 2014) In light of President Obama’s Memorandum directing federal agencies to take action on pollinator declines, groups and members of Congress are calling on the U.S. Environmental Protection Agency (EPA) to take meaningful steps to save our bees. In a letter to EPA, U.S.Representatives Earl Blumenauer (D-OR) and John Conyers (D-MI) are urging the agency to follow the lead of the U.S. Fish and Wildlife Service (FWS) and revise pesticide regulations to protect pollinators from exposure to bee-toxic neonicointoids. >>Ask Your Representative to Join the Call: Urge Your Member of Congress to Sign-on to the Blumenauer-Conyers Letter to EPA! Pollinators, including honeybees, bumblebees, butterflies, and other insects, play a critical role in our agriculture systems. More than 70% of America’s food sources are pollinated by bees and the worldwide economic value of bee”pollinated crops is as high as $125 billion per year. Since 2006, however, beekeepers have lost more than 30% of their hives annually””a huge threat to the vitality of our farms. Pollinators are a critical driver of healthy, nutrient-dense foods. One in three bites of food depends on honey bees and other pollinators, and without them food prices are sure to rise and some […]
