(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 […]

 (Beyond Pesticides, January 20, 2016) Aldi SĂĽd, the German supermarket chain with stores in the U.S., has become the first major European retailer to ban pesticides toxic to bees, including the neonicotinoids imidacloprid, clothianidin and thiamethoxam, from fruits and vegetables produced for their stores. Aldi has requested suppliers comply at the earliest possible time. In light of the growing pollinator crisis and due to public pressure, retailers in Europe and the U.S. are slowly beginning to make the switch away from bee-toxic pesticides. Beginning January 1, suppliers of fruits and vegetables to Aldi suppliers will have to ensure that their cultivation practices do not include the following eight pesticides identified as toxic to bees (thiamethoxam, chlorpyrifos,  clothianidin, cypermethrin, deltamethrin, fipronil, imidacloprid and sulfoxaflor) to meet  the new requirement. According to a press release from Greenpeace, the chemicals are used on various commodities in Europe  —thiamethoxam (used in lettuce and endive), chlorpyrifos, clothianidin (used in kohlrabi, herbs, Brussels sprouts, head cabbage, cauliflower and kale), cypermethrin (leek, head cabbage and leguminous vegetables), deltamethrin (cauliflower, peppers, eggplant, zucchini, cucumber, pea, head cabbage, tomato and lettuce),  imidacloprid (applied to apples, peaches, apricots and lettuce). Sulfoxaflor was recently granted regulatory approval in Europe, despite calls […]

(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 […]

(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 […]

(Beyond Pesticides, August 6, 2015) On July 28, the California Department of Pesticide (DPR) released a statement announcing recent sanctions for six California import firms who repeatedly violated pesticide regulations. Since December of last year, these six firms have been selling imported products that have been tainted with pesticides not approved for production or sale in the United States, including DDE, imidacloprid, chlorpyrifos, and the long-banned endosulfan. The fines range from $10,000 to $21,000. The six firms responsible for selling fruits and vegetables containing illegal pesticide residues are: Top Quality Produce, Inc. 623 Vineland Avenue, La Puente, CA 91746 will pay $10,000. On 5 separate occasions, the company sold produce such as Longan imported from Thailand, Burdock Root imported from Taiwan and Lychees imported from China with illegal pesticide residues. The produce was sold between November 2013 and July 2014. Yi Bao Produce Group, 3015 Leonis Blvd, Vernon CA 90058, will pay $15,000. On 7 separate occasions, the company sold produce imported from China such as Ginger, Taro Root, Longan and Fragrant Pear with illegal pesticide residues. The produce was sold between March 2013 and September 2014. Primary Export International Inc. 143 Mitchell Ave., South San Francisco, CA 94080, will […]

(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 5, 2015) In a major  victory for the environment and health, the Washington state Department of Ecology (Ecology) and oyster growers association agreed to withdraw a permit allowing the use of the neonicotinoid insecticide imidacloprid to control burrowing shrimp in oyster beds in Willapa Bay and Grays Harbor. The decision was reached in large part due to vocal public outrage over the plan, as consumers, environmental organizations, and prominent local chefs spoke out against the spraying. “One of our agency’s goals is to reduce toxics in our environment,” said Ecology Director Maia Bellon in a News Release published by the agency over the weekend. “We’ve heard loud and clear from people across Washington that this permit didn’t meet their expectations, and we respect the growers’ response.” In an article published in the Seattle Times Friday, the largest shellfish producer in country, Taylor Shellfish, announced it will not treat its oyster beds with imidacloprid in response to numerous calls, emails, and social media comments made by its customers. “Our customers spoke loud and clear today, and that speaks volumes to us,” said Bill Dewey, spokesman for Taylor Shellfish. Given Taylor Shellfish’s size, it is likely that the Willapa/Grays […]

(Beyond Pesticides, April 29, 2015) Much to the dismay of activists and concerned local residents, the Washington Department of Ecology (Ecology) approved a permit for the use of imidacloprid (a neonicotinoid) to combat a growing native population of burrowing shrimp that threatens valuable shellfish (oyster) beds in Willapa Bay and Grays Harbor in Washington state. Imidacloprid is known to be toxic to bees but is also toxic to aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. The shellfish industry is important to the Pacific Northwest, injecting an estimated $270 million or more into the region’s economy, and providing jobs for many. Washington’s tidelands, especially those in Willapa Bay, have been particularly productive for more than 100 years. However, according to shellfish growers, the burrowing shrimp (ghost shrimp, Neotrypaea californiensis,  and mud shrimp, Upogebia pugettensis) undermines the industry. The creatures burrow into shellfish beds, making the beds too soft for shellfish cultivation. Their burrowing churns the tidelands into a sticky muck, smothering the oysters. After several years of deliberations and studies, Ecology identified imidacloprid as its  preferred choice for eradicating the shrimp. According to the agency, imidacloprid disrupts the burrowing shrimps’ […]

(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 […]

(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 […]

(Beyond Pesticides, February 27, 2015) New research from the University of Minnesota presents some of the first evidence linking the bee-killing insecticides known as neonicotinoids to monarch butterfly deaths. The study finds that milkweed plants, which monarch butterflies need to survive, may also retain neonicotinoids from nearby plants, making milkweed toxic to monarchs. Monarch population numbers have fallen by 90% in less than 20 years. This year’s population was the second lowest since careful surveys began two decades ago. The critical driver of monarch decline  is the loss of larval host plants in their main breeding habitat, the midwestern Corn Belt. Monarchs lay eggs exclusively on plants in the milkweed family, the only food their larvae will eat. University of Minnesota entomologist Vera Krischik, Ph.D. fed butterflies milkweed plants treated with the neonicotinoid insecticide known as imidacloprid in amounts that might typically be found on backyard plants. While adult monarchs and painted lady butterflies were not affected, which, according to Dr. Krischik, indicates the ability of the adults to detoxify, the larvae of both species of butterflies died. During the course of the study, larvae fed on the treated plants for seven days. “For the monarch, nobody was left that […]

(Beyond Pesticides, January 23, 2015) Pesticide-centered Program Approved Despite 30,000 Opposition Letters. Eleven groups, including Beyond Pesticides and the City of Berkeley, sued the California Department of Food and Agriculture yesterday over the agency’s approval of a statewide “pest management” plan that allows pesticide spraying on schools, organic farms and residential yards, including aerial spraying over homes in rural areas. California regulators approved the program despite tens of thousands of public comment letters calling for a less toxic approach that would protect the vitality and resilience of the state’s food system and the economic interests of organic farmers. “Environmental review laws are there to prevent abuses,” says Jay Feldman, Executive Director of Beyond Pesticides, “Agencies cannot make unilateral decisions to ignore mandatory health and environmental safety standards.” “The state offers no evidence to support its conclusion that this pesticide-centered program will have no effect on our health,” said Debbie Friedman, cofounder of MOMS Advocating Sustainability. “As a parent, I am particularly disturbed that health risks of pesticide residues for children aged two and under are dismissed based on the absurd reasoning that infants spend most of their time indoors.” The approved program allows the state to use, without any additional […]

(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 12, 2014) The Oregon Department of Agriculture (ODA) has issued two civil penalties totaling $16,000 in connection with a pesticide application of imidacloprid, a chemical in the neonicotinoid class of insecticides connected to widespread bee decline, this summer that resulted in the death of nearly 1,000 bees at a Eugene apartment complex. Although ODA is taking actions to address pollinator protection, the frequent and continued occurrence of pesticide-related bee deaths indicates that current laws still fall woefully short of preventing these incidences. ODA’s Pesticide Program conducted an investigation that determined that Glass Tree Care and Spray Service, Inc. and its pesticide applicator violated Oregon’s pesticide control law through gross negligence. ODA is authorized to issue a civil penalty of up to $10,000 for violations that are the result of gross negligence, the maximum in this case issued to the company, a commercial pest control  operator based in Eugene. In addition, the applicator, James P. Mischkot, Jr., was issued a $6,000 civil penalty. When the incident in Eugene occurred, the trees were in full bloom and attracting pollinators.  In this case, ODA determined that the company and its applicator knew or should have known of this standard of […]

(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, 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 […]

(Beyond Pesticides, September 4, 2014) Beekeepers in Ontario, Canada are tired of losing bees and have decided to take matters into their own hands by filing a class action lawsuit against two makers of neonicotinoids. According to The Globe and Mail, the lawsuit alleges that Syngenta and Bayer CropScience were negligent in the design, sale, manufacture, and distribution of neonicotinoid pesticides and this negligence caused the plaintiffs, Sun Parlor Honey and Munro Honey, to suffer $450 million in damages. These alleged damages are based on losses from damaged or lost bee colonies, decreased honey production, lost profits, and unrecoverable costs ””all because of neonicotinoids. 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 of neonicotinoids systemic nature, pre-treatment practices, and other factors these dangerous pesticides have been linked to the global disappearance of honey bees and other non-target organisms, such as earthworms, birds, and aquatic invertebrates. For honey bees, the impacts have been astounding, with […]

(Beyond Pesticides, August 14, 2014) Pesticides are not the first thing to pop into mind when peering into a hot mug of steaming, pale green or murky black tea first thing in the morning. A recent report published by Greenpeace India announced the results of an investigation that tested for pesticide residues in branded tea. The verdict? Nearly 94% of the tea samples tested contained at least one of 34 different pesticides, while over half contained a toxic cocktail of more than 10 different pesticides. The residues found include DDT, which was banned for use in agriculture in India since 1989, and endosulfan, which was banned in 2011 by the Indian Supreme Court. Over half of the 49 samples contained illegal pesticides — either those that are not approved for use in tea cultivation or exceeded recommended limits. These pesticides include ones that have been long banned from agriculture and use in tea cultivation (DDT and triazophos), suspected mutagens and neurotoxicants (monocrotophos), and insecticides associated with the global decline in bee populations (neonicotinoids like thiacloprid and thiamethoxam). The most frequently detected pesticides include thiamethoxam (78%), cypermethrin (73%), acetamiprid (67%), thiacloprid (67%), DDT (67%), deltamethrin (67%), dicofol (61%), imidacloprid (61%), and […]

(Beyond Pesticides, August 11, 2014) Vermont Law School announced Friday that its campus is going neonicotinoid pesticide-free, making it the first higher-education campus in the country to earn official recognition from the  BEE Protective Campaign, led by Beyond Pesticides and Center for Food Safety. 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.

Jul
(Beyond Pesticides, July 23, 2014) New Zealand’s Environmental Protection Authority is stepping up its requirements for a higher level of scientific evidence regarding the safety and effects of neonicotinoids -pesticides linked to bee decline- before considering them for approval. Just last month, the Authority declined an application of thiamethoxam, a neonicotinoid, for use as a seed treatment, citing risks to bees. The decision follows a recent worldwide integrated assessment of research into systemic pesticides that concludes that neonicotinoid insecticides pose a serious risk to birds, honey bees and other pollinators, and a wide range of invertebrates, including earthworms. The international analysis of 800 peer-reviewed scientific reports confirms concerns of beekeepers and environmental groups throughout the world that long-term exposure to systemic pesticides at low, sublethal levels could be harmful to bees and a factor in declining bee populations. While it is unclear what these new stringent requirements are, the Authority, which works with New Zealand’s Beekeepers Association on the issue, already confirmed specific restrictions to products containing neonicotinoids to minimize the risk to insect pollinators. These restrictions include the prohibition of the use of neonicotinoids in areas where bees are foraging, or on plants and trees while they are in […]

(Beyond Pesticides, July 11, 2014) In addition to previous research on the direct impacts of pesticides on pollinators and other beneficials, a recent study published by Dutch scientists establishes an additional indirect link between neonicotinoid use and insect-eating birds. The report, which came out on Wednesday, provides evidence that neonicotinoids, a class of systemic pesticides, are indirectly hurting larger creatures by reducing insect prey populations such as mosquitoes and beetles. Researchers found that in certain areas of the Netherlands where water is contaminated with high concentrations of imidacloprid, a commonly used neonicotinoid, bird populations tend to decline by an average of 3.5 percent every year. Further analysis found that this spatial pattern of decline appeared only after the introduction of imidacloprid to the Netherlands in the mid-1990s, even after correcting for land-use changes that have been known to affect bird populations in farmland. “To our surprise we did find a very strong effect on birds”, said lead author of the study, Caspar Hallmann, a Ph.D. student from Radboud University in the Netherlands, to Reuters. In fact, according to the study, which was published in the journal Nature, nine of 15 bird species studied only eat insects and all feed insects […]

(Beyond Pesticides, June 25, 2014) Following last week’s celebration of “National Pollinator Week” and a presidential memorandum mandating federal action on bees, the first wide-scale scientific analysis has been released that links  two classes of pesticides  to declining bee populations. Twenty-nine scientists representing many disciplines reviewed over 800 peer-reviewed publications  on the impacts of systemic pesticides, and are recommending  more restrictions on neonicotinoid pesticides. This report is the single most comprehensive study of  neonicotinoids ever  undertaken. The “Worldwide Integrated Assessment (WIA)” ”” undertaken by the Task Force on Systemic Pesticides ”” documents significant harms to bees and ecosystems. While some aspects of this report have been broadly acknowledged  before (e.g. risks to honey bees), some, including risks to earthworms, birds and aquatic invertebrates, have not. The analysis focuses not only on impacts to particular  organisms and habitats, but also on  biodiversity and ecosystem impacts, taking a holistic view of pesticide effects. The scientists are calling for new, dramatic restrictions on bee-harming pesticides in the United States and beyond. The report  finds that the current regulatory system has failed to consider the full  range of pesticide effects. “This report should be a final wake up call for American regulators who have […]

(Beyond Pesticides, June 19, 2014) The city of Spokane, Washington is inching ever closer to a ban on neonicotinoid pesticides, a class of chemicals that has been linked to the global disappearance of honey bee populations. If the ban passes, Spokane will soon be part of a growing movement to protect pollinators. The Spokane City Council will be voting on the neonicotinoid ordinance this Monday, June 23.
