Judge Rules that EPA Neonicotinoid Registrations Violated Endangered Species Act

(Beyond Pesticides, May 11, 2017) On Monday, a federal judge in California ruled that the U.S. Environmental Protection Agency (EPA) violated the Endangered Species Act (ESA) when it issued 59 neonicotinoid insecticide registrations between 2007 and 2012 for pesticide products containing clothianidin and thiamethoxam. The original lawsuit against EPA, Ellis v. Housenger, was filed in March 2013, by beekeeper Steve Ellis and a coalition of other beekeepers and environmental groups, including Beyond Pesticides. The 2013 lawsuit focused on the EPA’s failure to protect pollinators from dangerous pesticides and challenged EPA’s oversight of the bee-killing pesticides, clothianidin and thiamethoxam, as well as the agency’s practice of “conditional registration” and labeling deficiencies. According to George Kimbrell, Center for Food Safety’s legal director and the lead plaintiffs’ counsel, “This is a vital victory. Science shows these toxic pesticides harm bees, endangered species and the broader environment. More than fifty years ago, Rachel Carson warned us to avoid such toxic chemicals, and the court’s ruling may bring us one step closer to preventing another Silent Spring.” The judge presiding over the case rejected claims by pesticide producers and their supporters that the plaintiffs failed to establish a causal link between the pesticides and the […]

Study Finds Neonicotinoids in Water Straight from the Tap

(Beyond Pesticides, April 5, 2017) A new study, Occurrence of Neonicotinoid Insecticides in Finished Drinking Water and Fate during Drinking Water Treatment, has detected neonicotinoids, a class of insecticides known for their detrimental effects on bees, in treated drinking water. This marks the first time that these insecticides have been found in water sourced straight from the tap. Federal regulators have not yet addressed safe levels of neonicotinoids in drinking water, so at this point, any detection of these chemicals is cause for concern. The study authors “report for the first time the presence of three neonicotinoids in finished drinking water and demonstrate their general persistence during conventional water treatment.” Drinking water samples “collected along the University of Iowa treatment train” over a seven week period, May through July, 2016 directly after corn and soy planting, find three neonicotinoids, clothianidin, imidacloprid, and thiamethoxam at levels ranging from 0.24 to 57.3 ng/L (nanogams per liter). The University of Iowa tap water is run through a water treatment plant that uses conventional treatment methods.  In contrast, the Iowa City water treatment methods (granular activated carbon filtration) result in substantially lower levels of the neonicotinoids. Additionally, the researchers found that extensive transformation of clothianidin […]

EPA Finds Risks to Bees from Neonicotinoid Insecticides, Fails to Act Accordingly

(Beyond Pesticides, January 17, 2017) On January 12, 2017, the U.S. Environmental Protection Agency (EPA) released major risk assessment documents on  pollinator exposure to bee-toxic neonicotinoid insecticides finding no significant risks, despite the large and growing body of science identifying the pesticides’ hazards. In the documents, EPA identifies risks posed to bees by several neonicotinoid insecticides, but suggests that no restriction on uses are imminent. In another decision meant to protect bees from acutely toxic pesticides, the agency is scaling back its original proposal in deference chemical-intensive agricultural interests. EPA’s long awaited pollinator assessments for the neonicotinoids: clothianidin, thiamethoxam, and dinotefuran, much like the 2016 pollinator assessment release for imidacloprid, identifies risks to bees from the agricultural applications (foliar, soil and seed) of these chemicals, including from pesticide drift. Observed effects include decline in worker bees, and subsequent declines in brood and pollen stores in the colony. EPAâ€s assessments continue to focus on honey bees, with cursory mention of wild, native bees. Once again, the assessments did not consider risks from exposures to contaminated water, guttation droplets, or soil, with EPA stating that, “The Agency lacks information to understand the relative importance of these other routes of exposures and/or to quantify potential risks […]

EPA Announcement on Bee-Toxic Pesticides At Odds with Latest Independent Science on Neonicotinoids

(Beyond Pesticides, January 13, 2016) Just prior to the U.S. Environmental Protection Agency (EPA) announcement on January 12 that several neonicotinoid insecticides “do not pose significant risks to bee colonies,” the preprint version of a new review of neonics identified the range of lethal and sublethal effects of the chemicals on non-target organisms.  The review, The Environmental Risks of Neonicotinoid Pesticides: a review of the evidence post-2013, authored by Dave Goulson, PhD, and Thomas James Wood, a PhD candidate, concludes that studies published since the 2013 European Food Safety (EFSA) published risk assessments show even greater risks. The EFSA assessment, which led to a moratorium on neonicotinoid uses, found that certain neonics on specific flowering crops pose a high risk to bees. With reference to the 2013 EFSA risk assessment conclusions as their baseline, the researchers summarize the difference in risk for certain categories, including: “Risk of exposure from and uptake of neonicotinoids in non-crop plants. Uptake of neonicotinoids by non-target plants was considered likely to be negligible, though a data gap was identified. Many studies have since been published demonstrating extensive uptake of neonicotinoids and their presence in the pollen, nectar and foliage of wild plants. Exposure from non-target plants clearly represents a Greater […]

Rusty Patch Bumblebee Officially Listed as an Endangered Species

(Beyond Pesticides, January 12, 2017) Yesterday marked a monumental event in the fight against pollinator declines, as the rusty patched bumblebee became the first bee species to officially be declared endangered by the U.S. Fish and Wildlife Service (FWS). According to FWS, endangered species designations are made when a species is “in danger of becoming extinct throughout all or a portion of their range.” Tom Melius, Service Midwest Regional Director for FWS, stated in a press release that, when it comes to this determination, “[FWS’s] top priority is to act quickly to prevent extinction of the rusty patched bumble bee. Listing the bee as endangered will help [the agency] mobilize partners and focus resources on finding ways right now to stop the decline.” Listed yesterday in the Federal Register, the ruling will go into effect February 10, 2017. This is a victory for environmental groups who have fought to protect the rusty patched bumble bee from widespread threats, such as habitat loss and pesticide use. According to FWS, the rusty patched bumble bee was once widespread across the United States and parts of Canada, but declined dramatically in the 1990s.  Since then, their populations have dwindled and their overall decline is estimated at 91 […]

Delaware Pollinator Protection Plan, Like Other State Plans, Fails to Eliminate Bee-Toxic Pesticides

(Beyond Pesticides, December 8, 2016) On Monday, the Delaware Department of Agriculture (DDA) released its Managed Pollinator Protection Plan, which allows for the continuation of widespread pesticide use in landscapes across the state. The plan includes voluntary strategies for farmers, beekeepers, landowners and pesticide applicators, but fails to include any recommendations for reducing or eliminating toxic pesticide use. DDA resorts to recommending approaches that include “best management practices,” strategies to increase pollinator forage on public and private lands, and advocating for the use of Driftwatch, an online initiative that focuses on pesticide drift. Driftwatch is a voluntary effort run by the non-profit, Fieldwatch, which, according to its website, was created by Purdue University Agricultural and Biological Engineering and Agricultural Communications departments and  Purdue University Cooperative Extension Specialists  “to help pesticide applicators and specialty crop growers communicate more effectively to promote awareness and stewardship activities to help prevent and manage drift effects.” Like other state pollinator protection plans,  there is little mention of pesticides, despite the fact that neonicotinoids (neonics) are highly toxic, persistent and systemic pesticides that have been widely implicated as a leading factor in pollinator decline. According to environmentalists and beekeepers, little meaningful action has been taken to […]

Canadian Environmental Groups Sue to Stop Bee-Toxic Pesticide Use

(Beyond Pesticides, July 12, 2016) Canadian environmental organizations sued the  Canadian Pest Management Regulatory Agency (PRMA) last week in a bid to overturn the approval of two neonicotinoid pesticides linked to the decline of honey bees and wild pollinators. The move comes amid growing awareness, action, and scientific evidence linking this widely used class of insecticides to the global decline of pollinator populations. The lawsuit, filed  by Ecojustice on behalf of  The David Suzuki Foundation, Friends of the Earth Canada, Ontario Nature, and the Wilderness Committee, argues that pesticide products containing two neonicotinoids, clothianidin and thiamethoxam, are unlawfully registered in Canada. The groups allege that PMRA failed to ensure that it had the data necessary to determine the environmental risks, particularly those concerning pollinators, posed by the chemicals. “The PMRA has taken a see-no-evil, hear-no-evil, speak-no-evil approach by repeatedly registering these neonicotinoid pesticides without important scientific information on their risks to pollinators,” said Charles Hatt, staff lawyer at Ecojustice. Under Canada’s Pest Control Products Act, PMRA must have “reasonable certainty” that a pesticide will not cause harm to the environment before it is registered. The groups also note that several thiamethoxam-based products have been registered by the agency for years […]

Study Finds Neonicotinoids Cause Compound-Specific Harm to Bumblebees

(Beyond Pesticides, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

Native Bees Found to Have Residues of Pesticides Linked to Their Steep Decline

(Beyond Pesticides, November 12, 2015) The U.S. Geological Survey (USGS) recently performed the first-ever study of pesticide residues on native bee populations and found that they are exposed to neonicotinoid insecticides, as well as other pesticides, at significant rates. This study digs deeper into a question  that was previously considered by a researcher who  studied chemical-intensive  apple orchards and linked a steep decline in wild or native bees to the application of pesticides. The USGS study  broadens understanding about the effects of toxic pesticides to native bee species, expanding field research that has principally focused on managed honey bee populations. The study tested for 122 different pesticides including bifenthrin, atrazine and chlorpyrifos, a chemical for which the U.S. Environmental Protection Agency (EPA) recently proposed to revoke all food tolerances in response to  a court-ordered deadline. According to study findings, 72% of bees tested positive for pesticide residues, raising concerns for the potential for unintended pesticides exposures where land uses overlap or are in proximity to one another.   Residues of pesticides found in bees in the study include  thiamethoxam, clothianidin, and imidacloprid, all of which are highly toxic neonicotinoids, a class of chemicals that have been linked to the global […]

EU Food Safety Watchdog Confirms Neonicotinoids Harmful to Bees

(Beyond Pesticides, August 28, 2015) The European Union’s food safety agency confirmed Wednesday that foliar spraying of neonicotinoids (neonics), the widely-used bee-toxic insecticides, poses a risk to bees, bolstering previous research that led to a two-year moratorium on the chemicals in the EU. The European Food Safety Authority (EFSA), which guides EU policymakers, said leaf spray containing three neonicotinoid pesticides — clothianidin, imidacloprid, and thiamethoxam — could harm bees. Previous research found that these chemicals pose a risk as seed treatments or granules, which prompted the European Commission to limit their use in  December 1, 2013. The use of the three neonicotinoid substances in seed or soil treatments is prohibited in the European Union for crops attractive to bees and for cereals other than winter cereals except in greenhouses. “They (the EFSA conclusions) confirm that the Commission was correct to take precautionary measures in 2013,” a Brussels-based EU executive said in a statement. Neonicotinoids have been found by  a growing body of scientific literature  to be linked to honey bee and pollinator decline. Recently, a  study  performed by the Food and Environment Research Agency (FERA) in the United Kingdom provides evidence confirming the link between neonicotinoid pesticides and continually increasing […]

Meeting Records Expose Industry’s Influence in UK’s Neonic Emergency Use Decision

(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 […]

UK Approves Emergency Application for Neonicotinoid Seed Treatment Use Despite Moratorium

(Beyond Pesticides, July 24, 2015) An emergency application was approved by the UK Department for Environment, Food, and Rural Affairs (DEFRA) on Wednesday that allows  farmers to use neonicotinoid seed treatment on 5 percent of oilseed rape crop (known as canola in the U.S.) this summer to control a flea beetle infestation. The emergency use, which has been granted for 120 days, allows growers to use Bayer CropScience’s Modesto (clothianidin) and Syngenta’s Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals knowns as neonicotinoids, which have been linked to pollinator decline. The request was the second one for the National Farmers Union (NFU) after the first request for a nationwide lifting of the two-year moratorium on neonicotinoid use was rejected. The NFU said it was “frustrated” at having to put in an application for a smaller area. There have been numerous attempts to shroud the application process in secrecy. DEFRA told its expert committee on pesticides (ECP) to halt its  normal practice of publishing the minutes  of meetings at which the neonicotinoid applications were discussed, in order to avoid “provoking representations from different interest groups.” Additionally, according to the Guardian, the UK government […]

Research Finds Bees Prefer Foods Treated with Bee-Killing Insecticides

(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 […]

Portland, Oregon to Vote on Neonic Ban on City Property

(Beyond Pesticides, March 27, 2015) Portland, Oregon is considering a ban on neonicotinoids, a class of insecticides linked to bee deaths, from use on city property. If the measure passes, Portland will join a long list of towns and communities, including Eugene (Oregon),  Skagway (Alaska),  and, in Washington State, Thurston County,  Seattle, and Spokane. Under the proposed ordinance, city officials would not be permitted to use or buy neonicotinoids or similar pesticides on city lands or in city buildings and would urge stores to label products, such as plants and seeds treated with neonicotinoids. The proposal also applies to city contractors. Additionally, the proposed ban on neonicotinoids and neonicotinoid-like insecticides would not apply immediately to two city rose gardens. Officials say the rose midge, a pest, is difficult to eradicate with the insecticide. Instead the city will look for an alternative method using a pilot project at Peninsula Park in North Portland to test alternative non-toxic insecticides. That proposal would be phased in with a deadline of December 2017 to eliminate all neonicotinoid-based products. The proposal cites seven separate bumble bee incidents in Oregon related to the application of neonicotinoids on trees since June 2013, documented by the state’s Department […]

Oregon Bans Four Bee-Killing Insecticides on Linden Trees

(Beyond Pesticides, March 6, 2015) Last Friday, Oregon enacted a new rule which bans the use of four types of bee-killing insecticides, including  imidacloprid, clothianidin, thiamethoxam and dinotefuran, regardless of application method on linden trees and other Tilia species. The four insecticides that are now illegal to spray on Tilia trees are all in the neonicotinoid chemical class which are implicated in pollinator decline, and represents a step forward in protecting bees. However, Tilia trees are not the only route of exposure that bees and other pollinators have to neonics, which are currently applied to fields across the U.S. as seed treatment. The rule comes at the request of the Oregon Department of Agriculture (ODA) following several bee-kill incidents in Oregon since June 2013, when more than 50,000 bumblebees were killed after dinotefuran was sprayed on trees in a shopping mall parking lot in Wilsonville, Oregon. After the incident in Wilsonville, ODA initially placed restrictions on two of the chemicals, dinotefuran and imidacloprid on Tilia trees, and the state launched a task force to look at protections for pollinators. The group came out with a range of recommendations including increased outreach and education about bees and support for bee habitat […]

100+ Businesses Urge Obama Administration to Suspend Bee-Toxic Pesticides

(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 […]

Over 100 Scientists Call for Action on Bee-Toxic Pesticides

(Beyond Pesticides, November 26, 2014) Last week, over 100 scientists from diverse disciplines released a letter citing the growing body of scientific evidence that neonicotinoids and other systemic pesticides harm bees, and called on leaders of President Barack Obama’s Pollinator Health Task Force to quickly take action on pesticides to protect and promote healthy populations of bees and other pollinators. The letter was submitted in response to the recent “listening sessions” hosted by U.S. Environmental Protection Agency (EPA) and the U.S. Department of Agriculture (USDA). These sessions were held by the agencies to  collect public  feedback  on federal efforts on pollinator protection, and the Task Force convened to develop a National Pollinator Health Strategy. In June, the White House issued a Presidential Memorandum directing federal agencies to  join the  Pollinator Health Task Force, led by USDA, to develop pollinator health solutions. The 108 scientists ””whose areas of expertise include entomology, agronomy, ecology, ecotoxicology”” called on Task Force co-chairs, EPA Administrator Gina McCarthy, and USDA Secretary Tom Vilsack, to place a moratorium on the use of neonicotinoid pesticides in the U.S., and increase investment, research and funding for growers to adopt alternatives. In the letter, the scientists note that, “While gaps […]

Pesticides Impair Bees’ Immune Function, Pure Pollen Diet Has Positive Effect

(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 […]

USDA To Provide Additional $4 million for Honey Bee Habitat, No Mention of Pesticides

(Beyond Pesticides, October 31, 2014) Without any mention of the role of pesticides in bee decline, or emphasis on organic practices to help pollinators, Agriculture Secretary Tom Vilsack announced Wednesday that more than $4 million in technical and financial assistance will be provided to help farmers and ranchers in the Midwest improve the health of honey bees. The announcement renews and expands on a $3 million pilot investment last spring to create pollinator-friendly habitat in five Midwestern states. The effort responds to the Presidential Memorandum, which directs USDA to expand the acreage and forage value in its conservation programs. The Memorandum, issued at the close of National Pollinator Week 2014, directed federal agencies to establish a Pollinator Health Task Force, and tasked agency leads at the U.S. Department of Agriculture (USDA) and U.S. Environmental Protection Agency (EPA) to develop a pollinator health strategy within 180 days that supports and fosters pollinator habitat. “The future of America’s food supply depends on honey bees, and this effort is one way USDA is helping improve the health of honey bee populations,” Vilsack said. “Significant progress has been made in understanding the factors that are associated with Colony Collapse Disorder and the overall health […]

EPA Finds Neonicotinoid Seed Treatments To Be of Little or No Benefit

(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 […]

Emory University To Ban Neonicotinoids from Campus

(Beyond Pesticides, September 10, 2014) As bee and other pollinator populations continue to decline around the world, with clear evidence pointing to neonicotinoid pesticides as a prime cause, Emory University announced last week that it will be eliminating the use of this controversial class of chemicals from its campus, joining institutions and  communities like University of Vermont Law School, Spokane  (Washington),  Eugene (Oregon), and Shorewood (Minnesota). Neonicotinoids are a class of insecticides that share a common mode of action that affects the central nervous system of insects,  affecting the organisms’ ability to function. These systemic pesticides, which move through the plant’s vascular system and express themselves through pollen and nectar, include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. A continually growing body of science has implicated neonicotinoids, which are applied to or incorporated into seeds for agricultural, ornamental and garden plants, as a key factor in recent global bee die-offs. Beekeepers across the country reported losses of 40 to 90 percent of their bees last winter. The implications of this loss are staggering —one in every three bites of food is reliant on bee pollination, and pollinators make possible  $20-30 billion of annual U.S. agricultural production. Last week, Emory […]

Vermont Law School Becomes First BEE Protective Campus!

The university joins an expanding list of communities across the country to take action to protect pollinators in the absence of federal regulation, including Eugene, OR,   Spokane, WA, and most recently, Shorewood, Minnesota. “We are very pleased that Vermont Law School has taken the lead on going neonic-free, and hope other universities and communities will follow suit,” said Nichelle Harriott, Senior Staff Scientist at Beyond Pesticides. Neonicotinoids are a class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. These systemic pesticides, which  move through the plant’s vascular system and express themselves through pollen and nectar,  include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. A growing body of science has implicated neonicotinoids, which are applied to or  incorporated into seeds for agricultural, ornamental  and garden plants, as a key factor in recent global bee die-offs. Beekeepers across the country reported losses […]

Midwest Waterways Contaminated with Persistent Neonicotinoid Pesticides

(Beyond Pesticides, July 25, 2014) A new U.S. Geological Survey (USGS) study published yesterday found neonicotinoid pesticides persistent and prevalent in streams throughout the Midwestern United States. The study is the first to investigate the presence of neonicotinoids on a wide-scale level in the Midwest. While neonicotinoid use has increased throughout the country, the Midwest in particular has seen a dramatic increase over the last decade. The use of clothianidin, one of the chemicals studied, on corn in Iowa alone has approximately doubled in just two years, from 2011 and 2013. Neonicotinoids are chemically similar to nicotine and are pesticides that are toxic to a broad range of insect pests. They are also known as systemic pesticides, which are pesticides that spread throughout the entire plant structure, making everything from roots to pollen toxic to organisms that come in contact with it. As a result, neonicotinoids have been linked to the global disappearance of honey bees and other nontarget organisms, such as earthworms, birds, and aquatic invertebrates. USGS scientist Kathryn Kuivila, Ph.D., stated, “Neonicotinoid insecticides are receiving increased attention by scientists as we explore the possible links between pesticides, nutrition, infectious disease, and other stress factors in the environment possibly […]
